Debian Lenny to Debian Squeeze upgrade problems

- by Roland Soós

Hi! Yesterday I made a dist-upgrade on my Debian Lenny server. I thought it will be easy as an usual upgrade, but it's not. I got a lot of problem after the update: # apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: linux-image-2.6-amd64 : Depends: linux-image-2.6.32-5-amd64 but it is not installed E: Unmet dependencies. Try using -f. Then I tried the suggestion: # apt-get -f install Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following packages were automatically installed and are no longer required: libio-compress-base-perl libatk1.0-0 libts-0.0-0 libmime-types-perl libc-client2007b libgtk2.0-common libxfixes3 libgsf-1-common hicolor-icon-theme libfile-remove-perl libxcomposite1 libltdl3-dev libneon27 libmd5-perl libwmf0.2-7 libilmbase6 libatk1.0-data djvulibre-desktop libdirectfb-1.0-0 fam libxinerama1 libcroco3 libopenexr6 libgsf-1-114 libmail-box-perl libdjvulibre21 openssl-blacklist librsvg2-2 libio-compress-zlib-perl libsysfs2 libbeecrypt6 libxdamage1 libobject-realize-later-perl libuser-identity-perl libgtk2.0-bin libxi6 libxcursor1 portmap libxrandr2 libgtk2.0-0 Use 'apt-get autoremove' to remove them.

Tuning performance of Ubuntu 10.04 on Compaq Evo W4000.

- by Fantomas

Hi, I got this computer free and installed Ubuntu 10.04 on it + updates, plus followed the following tutorial all the way: http://www.unixmen.com/linux-tutorials/937-things-to-do-after-installing-ubuntu-1004-lts-lucid-lynx I love the Docky which comes with it, but the computer has been running rather slowly. The System: kernel 2.6.32-22-generic Gnome 2.30.0 (I like Gnome!) Memory: 1GB Processor: Intel (R) Pentium (R) 4 CPU 1700 MHz (needless to say, it is 32 bit). I think I dedicated 128 Mb to video memory while installing, but cannot find this setting now. I did also install an NVidia driver for the 3D card, so I probably want to reclaim that memory back. I want to trim the fat but I also want to keep some of the sex appeal of Ubuntu 10.04. I will gift this computer to a friend, who will use it for Internet, music, videos, word processing, Skype and instant messaging - he is non-technical, so this hardware and Linux should work for him; I just need to speed it up while keeping the good software and having a nice UI. I sort of know my way around Linux, but not that well. Feel free to ask me to run particular commands if you want more info. For starters, here are the services below. Which ones can I kill and how? What else can go? There is no need to run ssh or ftp or http or ntp servers. As I said before, this computer is for non-technical person. There is also absolutely no bluetooth or wireless networking needed - it will feed off a regular ethernet cable. What I do not want to do is reinstall some other distro or recompile a kernel. I want to make it 80% perfect spending 20% of the energy :) Thanks! $ service --status-all [ ? ] acpi-support [ ? ] acpid [ ? ] alsa-mixer-save [ ? ] anacron [ - ] apparmor [ ? ] apport [ ? ] atd [ ? ] avahi-daemon [ ? ] binfmt-support [ - ] bluetooth [ - ] bootlogd [ - ] brltty [ ? ] console-setup [ ? ] cron [ + ] cups [ ? ] dbus [ ? ] dmesg [ ? ] dns-clean [ ? ] failsafe-x [ - ] fancontrol [ ? ] gdm [ - ] grub-common [ ? ] hostname [ ? ] hwclock [ ? ] hwclock-save [ ? ] irqbalance [ - ] kerneloops [ ? ] killprocs [ - ] lm-sensors [ ? ] module-init-tools [ ? ] network-interface [ ? ] network-interface-security [ ? ] network-manager [ ? ] networking [ ? ] ondemand [ ? ] pcmciautils [ ? ] plymouth [ ? ] plymouth-log [ ? ] plymouth-splash [ ? ] plymouth-stop [ ? ] pppd-dns [ ? ] procps [ + ] pulseaudio [ ? ] rc.local [ - ] rsync [ ? ] rsyslog [ - ] saned [ ? ] screen-cleanup [ ? ] sendsigs [ ? ] speech-dispatcher [ ? ] stop-bootlogd [ ? ] stop-bootlogd-single [ ? ] udev [ ? ] udev-finish [ ? ] udevmonitor [ ? ] udevtrigger [ ? ] ufw [ ? ] umountfs [ ? ] umountnfs.sh [ ? ] umountroot [ ? ] unattended-upgrades [ - ] urandom [ + ] winbind [ ? ] wpa-ifupdown [ - ] x11-common

How should I config Apache2.2?

I tried to configure Apache 2.2.17 with PHP5.4 using this manual. But when I restarted my PC and went to http://localhost/phpinfo.php, I received this message: Not Found.

Puppet gives SSL error because master is not running?

- by Daniel Huger

I started with two clean machines this time. My master is running 12.04 Version: 2.7.11-1ubuntu2 Depends: ruby1.8, puppetmaster-common (= 2.7.11-1ubuntu2) My client is 10.04 Version: 2.6.3-0ubuntu1~lucid1 Depends: puppet-common (= 2.6.3-0ubuntu1~lucid1), ruby1.8 To setup Puppet tutorial: http://shapeshed.com/setting-up-puppet-on-ubuntu-10-04/ To connect master and client: http://shapeshed.com/connecting-clients-to-a-puppet-master/ The first time I tried to connect master to client failed with SSL_connect error. So I did rm -rf /etc/puppet/ssl/ to remove all the keys inside ssl folders. It looked like it work.... BUT client# puppet agent --server puppet --waitforce 60 --test /usr/lib/ruby/1.8/facter/util/resolution.rb:46: warning: Insecure world writable dir /etc/condor in PATH, mode 040777 /usr/lib/ruby/1.8/puppet/defaults.rb:67: warning: Insecure world writable dir /etc/condor in PATH, mode 040777 info: Creating a new SSL key for giab10 warning: peer certificate won't be verified in this SSL session info: Caching certificate for ca warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session info: Creating a new SSL certificate request for mybox123 info: Certificate Request fingerprint (md5): XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session info: Caching certificate for mybox123 err: Could not retrieve catalog from remote server: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed warning: Not using cache on failed catalog It cached but then it couldn't retrieve it. Let me stop here.... worrying I would mess something up. But let's check master's status. * master is not running WoW.... ??? master# service puppetmaster start * Starting puppet master [OK] master# service puppetmaster status * master is not running I think time is sync. Well, we are behind a firewall so the port to sync time is disbaled. I checked with date and they seem okay. What about master not running? Is that the cause? Any help is appreciated.

Set up lnux box for hosting a-z

- by microchasm

I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP: To upgrade PHP to the latest version, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! cd /tmp #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm #rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm #rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. [will list all packages available in the IUS repo] rpm -qa | grep php [will list installed packages needed to be removed. the installed packages need to be removed before you can install the IUS packages otherwise there will be conflicts] #yum shell >remove php-gd php-cli php-odbc php-mbstring php-pdo php php-xml php-common php-ldap php-mysql php-imap Setting up Remove Process >install php53 php53-mcrypt php53-mysql php53-cli php53-common php53-ldap php53-imap php53-devel >transaction solve >transaction run Leaving Shell #php -v PHP 5.3.2 (cli) (built: Apr 6 2010 18:13:45) This process removes the old version of PHP and installs the latest. To upgrade mysql: Pretty much the same process as above with PHP #/etc/init.d/mysqld stop [OK] rpm -qa | grep mysql [installed mysql packages] #yum shell >remove mysql mysql-server Setting up Remove Process >install mysql51 mysql51-server mysql51-devel >transaction solve >transaction run Leaving Shell #service mysqld start [OK] #mysql -v Server version: 5.1.42-ius Distributed by The IUS Community Project The above upgrade instructions courtesy of IUS wiki: http://wiki.iuscommunity.org/Doc/ClientUsageGuide Create a chroot jail to hold sftp user via rssh. This will force SCP/SFTP and will circumvent traditional FTP server setup. #cd /tmp #wget http://dag.wieers.com/rpm/packages/rssh/rssh-2.3.2-1.2.el5.rf.x86_64.rpm #rpm -ivh rssh-2.3.2-1.2.el5.rf.x86_64.rpm #useradd -m -d /home/dev -s /usr/bin/rssh dev #passwd dev Edit /etc/rssh.conf to grant access to SFTP to rssh users. #vi /etc/rssh.conf Uncomment line allowscp This allows me to connect to the machine via SFTP protocol in Transmit (my FTP program of choice; I'm sure it's similar with other FTP apps). Above instructions for SFTP appropriated (with appreciation!) from http://www.cyberciti.biz/tips/linux-unix-restrict-shell-access-with-rssh.html And this is where I'm at. I will keep editing this as I make progress. Any tips on how to Configure virtual interfaces/ip based virtual hosts for SSL, setting up a CA, or anything else would be appreciated.

Installing chrome in Centos 6.2 (Final)

- by usjes

I need to install chrome in a dedicated centos server where I only access via ssh, it doesn't have X or any windows graphical stuff. I need it to be able to pack extensions using google-chrome --pack-extension. I tried adding this to /etc/yum.repos.d/google.repo [google-chrome] name=google-chrome - 32-bit baseurl=http://dl.google.com/linux/chrome/rpm/stable/i386 enabled=1 gpgcheck=1 gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub And then yum install google-chrome-stable, but there's a huge list of dependencies problems: How can I install chrome without breaking anything else? UPDATE: Ok, I installed perl-CGI from .rpm because yum couldn't find it, now dependencies resolve and it show me this list of packages to install: Dependencies Resolved ============================================================================================================================================================================================================================================= Package Arch Version Repository Size ============================================================================================================================================================================================================================================= Installing: google-chrome-stable x86_64 19.0.1084.52-138391 google-chrome 35 M Installing for dependencies: ConsoleKit x86_64 0.4.1-3.el6 base 82 k ConsoleKit-libs x86_64 0.4.1-3.el6 base 17 k GConf2 x86_64 2.28.0-6.el6 base 964 k ORBit2 x86_64 2.14.17-3.1.el6 base 168 k bc x86_64 1.06.95-1.el6 base 110 k cdparanoia-libs x86_64 10.2-5.1.el6 base 47 k cups x86_64 1:1.4.2-44.el6_2.3 updates 2.3 M dbus x86_64 1:1.2.24-5.el6_1 base 207 k desktop-file-utils x86_64 0.15-9.el6 base 47 k ed x86_64 1.1-3.3.el6 base 72 k eggdbus x86_64 0.6-3.el6 base 91 k foomatic x86_64 4.0.4-1.el6_1.1 base 251 k foomatic-db noarch 4.0-7.20091126.el6 base 980 k foomatic-db-filesystem noarch 4.0-7.20091126.el6 base 4.4 k foomatic-db-ppds noarch 4.0-7.20091126.el6 base 19 M ghostscript x86_64 8.70-11.el6_2.6 updates 4.4 M ghostscript-fonts noarch 5.50-23.1.el6 base 751 k gstreamer x86_64 0.10.29-1.el6 base 764 k gstreamer-plugins-base x86_64 0.10.29-1.el6 base 942 k gstreamer-tools x86_64 0.10.29-1.el6 base 23 k iso-codes noarch 3.16-2.el6 base 2.4 M lcms-libs x86_64 1.19-1.el6 base 100 k libIDL x86_64 0.8.13-2.1.el6 base 83 k libXScrnSaver x86_64 1.2.0-1.el6 base 19 k libXfont x86_64 1.4.1-2.el6_1 base 128 k libXv x86_64 1.0.5-1.el6 base 21 k libfontenc x86_64 1.0.5-2.el6 base 24 k libgudev1 x86_64 147-2.40.el6 base 59 k libmng x86_64 1.0.10-4.1.el6 base 165 k libogg x86_64 2:1.1.4-2.1.el6 base 21 k liboil x86_64 0.3.16-4.1.el6 base 121 k libtheora x86_64 1:1.1.0-2.el6 base 129 k libvisual x86_64 0.4.0-9.1.el6 base 135 k libvorbis x86_64 1:1.2.3-4.el6_2.1 updates 168 k mailx x86_64 12.4-6.el6 base 234 k man x86_64 1.6f-29.el6 base 263 k mesa-libGLU x86_64 7.11-3.el6 base 201 k nvidia-graphics195.30-libs x86_64 195.30-120.el6 atrpms 13 M openjpeg-libs x86_64 1.3-7.el6 base 59 k pax x86_64 3.4-10.1.el6 base 69 k phonon-backend-gstreamer x86_64 1:4.6.2-20.el6 base 125 k polkit x86_64 0.96-2.el6_0.1 base 158 k poppler x86_64 0.12.4-3.el6_0.1 base 557 k poppler-data noarch 0.4.0-1.el6 base 2.2 M poppler-utils x86_64 0.12.4-3.el6_0.1 base 73 k portreserve x86_64 0.0.4-4.el6_1.1 base 22 k qt x86_64 1:4.6.2-20.el6 base 4.0 M qt-sqlite x86_64 1:4.6.2-20.el6 base 50 k qt-x11 x86_64 1:4.6.2-20.el6 base 12 M qt3 x86_64 3.3.8b-30.el6 base 3.5 M redhat-lsb x86_64 4.0-3.el6.centos base 24 k redhat-lsb-graphics x86_64 4.0-3.el6.centos base 12 k redhat-lsb-printing x86_64 4.0-3.el6.centos base 11 k sgml-common noarch 0.6.3-32.el6 base 43 k time x86_64 1.7-37.1.el6 base 26 k tmpwatch x86_64 2.9.16-4.el6 base 31 k xdg-utils noarch 1.0.2-17.20091016cvs.el6 base 58 k xml-common noarch 0.6.3-32.el6 base 9.5 k xorg-x11-font-utils x86_64 1:7.2-11.el6 base 75 k xz x86_64 4.999.9-0.3.beta.20091007git.el6 base 137 k xz-lzma-compat x86_64 4.999.9-0.3.beta.20091007git.el6 base 16 k Transaction Summary ============================================================================================================================================================================================================================================= Install 62 Package(s) Is it safe to continue and install all that or could I break something already installed?

Application I use requires OpenSSL 0.9.8, which was already installed (0.9.8e to be specific) on my CentOS alongside 1.0.1e which unfortunately is used by default. I tried to change libssl.so.10 symbolic link to point to the older version like so: [mckulpa@nuance-vm ~]$ ldd /usr/bin/openssl /usr/bin/openssl: /usr/lib64/libssl.so.10: no version information available (required by /usr/bin/openssl) linux-vdso.so.1 => (0x00007fff2edff000) libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007f664457c000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x0000003927600000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x0000003926200000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x0000003925a00000) libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x0000003926e00000) libcrypto.so.10 => /usr/lib64/libcrypto.so.10 (0x0000003927200000) libdl.so.2 => /lib64/libdl.so.2 (0x000000391a600000) libz.so.1 => /lib64/libz.so.1 (0x000000391aa00000) libc.so.6 => /lib64/libc.so.6 (0x0000003919e00000) libcrypto.so.6 => /usr/lib64/libcrypto.so.6 (0x00007f664421d000) libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x0000003925e00000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x0000003926a00000) libresolv.so.2 => /lib64/libresolv.so.2 (0x000000391be00000) libpthread.so.0 => /lib64/libpthread.so.0 (0x000000391a200000) /lib64/ld-linux-x86-64.so.2 (0x0000003919600000) libselinux.so.1 => /lib64/libselinux.so.1 (0x000000391b600000) [mckulpa@nuance-vm ~]$ export LD_LIBRARY_PATH=~/libs:$LD_LIBRARY_PATH [mckulpa@nuance-vm ~]$ echo $LD_LIBRARY_PATH /home/mckulpa/libs:/usr/local/Nuance/Recognizer_Service/amd64/lib:/usr/local/Nuance/OAM/x86/lib:/usr/local/Nuance/Common/x86/lib:/usr/local/Nuance/Common/amd64/lib [mckulpa@nuance-vm ~]$ ldd /usr/bin/openssl /usr/bin/openssl: /home/mckulpa/libs/libssl.so.10: no version information available (required by /usr/bin/openssl) linux-vdso.so.1 => (0x00007fff91dbc000) libssl.so.10 => /home/mckulpa/libs/libssl.so.10 (0x00007ffe1af50000) libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x0000003927600000) libkrb5.so.3 => /lib64/libkrb5.so.3 (0x0000003926200000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x0000003925a00000) libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x0000003926e00000) libcrypto.so.10 => /usr/lib64/libcrypto.so.10 (0x0000003927200000) libdl.so.2 => /lib64/libdl.so.2 (0x000000391a600000) libz.so.1 => /lib64/libz.so.1 (0x000000391aa00000) libc.so.6 => /lib64/libc.so.6 (0x0000003919e00000) libcrypto.so.6 => /usr/lib64/libcrypto.so.6 (0x00007ffe1abd9000) libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x0000003925e00000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x0000003926a00000) libresolv.so.2 => /lib64/libresolv.so.2 (0x000000391be00000) libpthread.so.0 => /lib64/libpthread.so.0 (0x000000391a200000) /lib64/ld-linux-x86-64.so.2 (0x0000003919600000) libselinux.so.1 => /lib64/libselinux.so.1 (0x000000391b600000) [mckulpa@nuance-vm ~]$ ls -l libs total 316 -rwxr-xr-x. 1 mckulpa mckulpa 321224 05-28 14:59 libssl.so.0.9.8e lrwxrwxrwx. 1 mckulpa mckulpa 16 05-28 15:18 libssl.so.10 -> libssl.so.0.9.8e but all I get is a warning and still the 1.0.1e version is printed out: [mckulpa@nuance-vm ~]$ openssl version openssl: /home/mckulpa/libs/libssl.so.10: no version information available (required by openssl) OpenSSL 1.0.1e-fips 11 Feb 2013 Any ideas how to do this properly?

Set up lnux box for hosting a-z [apache mysql php ssl]

- by microchasm

I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP: To upgrade PHP to the latest version, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! cd /tmp #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm #rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm #wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm #rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. [will list all packages available in the IUS repo] rpm -qa | grep php [will list installed packages needed to be removed. the installed packages need to be removed before you can install the IUS packages otherwise there will be conflicts] #yum shell >remove php-gd php-cli php-odbc php-mbstring php-pdo php php-xml php-common php-ldap php-mysql php-imap Setting up Remove Process >install php53 php53-mcrypt php53-mysql php53-cli php53-common php53-ldap php53-imap php53-devel >transaction solve >transaction run Leaving Shell #php -v PHP 5.3.2 (cli) (built: Apr 6 2010 18:13:45) This process removes the old version of PHP and installs the latest. To upgrade mysql: Pretty much the same process as above with PHP #/etc/init.d/mysqld stop [OK] rpm -qa | grep mysql [installed mysql packages] #yum shell >remove mysql mysql-server Setting up Remove Process >install mysql51 mysql51-server mysql51-devel >transaction solve >transaction run Leaving Shell #service mysqld start [OK] #mysql -v Server version: 5.1.42-ius Distributed by The IUS Community Project And this is where I'm at. I will keep editing this as I make progress. Any tips on how to Configure Virtualhosts for SSL, setting up a CA, setting up SFTP with openSSH, or anything else would be appreciated.

Network config / gear question

- by mcgee1234

I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

Multi-tenant ASP.NET MVC – Introduction

- by zowens

I’ve read a few different blogs that talk about multi-tenancy and how to resolve some of the issues surrounding multi-tenancy. What I’ve come to realize is that these implementations overcomplicate the issues and give only a muddy implementation! I’ve seen some really illogical code out there. I have recently been building a multi-tenancy framework for internal use at eagleenvision.net. Through this process, I’ve realized a few different techniques to make building multi-tenant applications actually quite easy. I will be posting a few different entries over the issue and my personal implementation. In this first post, I will discuss what multi-tenancy means and how my implementation will be structured. So what’s the problem? Here’s the deal. Multi-tenancy is basically a technique of code-reuse of web application code. A multi-tenant application is an application that runs a single instance for multiple clients. Here the “client” is different URL bindings on IIS using ASP.NET MVC. The problem with different instances of the, essentially, same application is that you have to spin up different instances of ASP.NET. As the number of running instances of ASP.NET grows, so does the memory footprint of IIS. Stack Exchange shifted its architecture to multi-tenancy March. As the blog post explains, multi-tenancy saves cost in terms of memory utilization and physical disc storage. If you use the same code base for many applications, multi-tenancy just makes sense. You’ll reduce the amount of work it takes to synchronize the site implementations and you’ll thank your lucky stars later for choosing to use one application for multiple sites. Multi-tenancy allows the freedom of extensibility while relying on some pre-built code. You’d think this would be simple. I have actually seen a real lack of reference material on the subject in terms of ASP.NET MVC. This is somewhat surprising given the number of users of ASP.NET MVC. However, I will certainly fill the void ;). Implementing a multi-tenant application takes a little thinking. It’s not straight-forward because the possibilities of implementation are endless. I have yet to see a great implementation of a multi-tenant MVC application. The only one that comes close to what I have in mind is Rob Ashton’s implementation (all the entries are listed on this page). There’s some really nasty code in there… something I’d really like to avoid. He has also written a library (MvcEx) that attempts to aid multi-tenant development. This code is even worse, in my honest opinion. Once I start seeing Reflection.Emit, I have to assume the worst :) In all seriousness, if his implementation makes sense to you, use it! It’s a fine implementation that should be given a look. At least look at the code. I will reference MvcEx going forward as a comparison to my implementation. I will explain why my approach differs from MvcEx and how it is better or worse (hopefully better). Core Goals of my Multi-Tenant Implementation The first, and foremost, goal is to use Inversion of Control containers to my advantage. As you will see throughout this series, I pass around containers quite frequently and rely on their use heavily. I will be using StructureMap in my implementation. However, you could probably use your favorite IoC tool instead. <RANT> However, please don’t be stupid and abstract your IoC tool. Each IoC is powerful and by abstracting the capabilities, you’re doing yourself a real disservice. Who in the world swaps out IoC tools…? No one!</RANT> (It had to be said.) I will outline some of the goodness of StructureMap as we go along. This is really an invaluable tool in my tool belt and simple to use in my multi-tenant implementation. The second core goal is to represent a tenant as easily as possible. Just as a dependency container will be a first-class citizen, so will a tenant. This allows us to easily extend and use tenants. This will also allow different ways of “plugging in” tenants into your application. In my implementation, there will be a single dependency container for a single tenant. This will enable isolation of the dependencies of the tenant. The third goal is to use composition as a means to delegate “core” functions out to the tenant. More on this later. Features In MvcExt, “Modules” are a code element of the infrastructure. I have simplified this concept and have named this “Features”. A feature is a simple element of an application. Controllers can be specified to have a feature and actions can have “sub features”. Each tenant can select features it needs and the other features will be hidden to the tenant’s users. My implementation doesn’t require something to be a feature. A controller can be common to all tenants. For example, (as you will see) I have a “Content” controller that will return the CSS, Javascript and Images for a tenant. This is common logic to all tenants and shouldn’t be hidden or considered a “feature”; Content is a core component. Up next My next post will be all about the code. I will reveal some of the foundation to the way I do multi-tenancy. I will have posts dedicated to Foundation, Controllers, Views, Caching, Content and how to setup the tenants. Each post will be in-depth about the issues and implementation details, while adhering to my core goals outlined in this post. As always, comment with questions of DM me on twitter or send me an email.

TFS 2010 Build Custom Activity for Merging Assemblies

- by Jakob Ehn

*** The sample build process template discussed in this post is available for download from here: http://cid-ee034c9f620cd58d.office.live.com/self.aspx/BlogSamples/ILMerge.xaml *** In my previous post I talked about library builds that we use to build and replicate dependencies between applications in TFS. This is typically used for common libraries and tools that several other application need to reference. When the libraries grow in size over time, so does the number of assemblies. So all solutions that uses the common library must reference all the necessary assemblies that they need, and if we for example do a refactoring and extract some code into a new assembly, all the clients must update their references to reflect these changes, otherwise it won’t compile. To improve on this, we use a tool from Microsoft Research called ILMerge (Download from here). It can be used to merge several assemblies into one assembly that contains all types. If you haven’t used this tool before, you should check it out. Previously I have implemented this in builds using a simple batch file that contains the full command, something like this: "%ProgramFiles(x86)%\microsoft\ilmerge\ilmerge.exe" /target:library /attr:ClassLibrary1.bl.dll /out:MyNewLibrary.dll ClassLibrary1.dll ClassLibrar2.dll ClassLibrary3.dll This merges 3 assemblies (ClassLibrary1, 2 and 3) into a new assembly called MyNewLibrary.dll. It will copy the attributes (file version, product version etc..) from ClassLibrary1.dll, using the /attr switch. For more info on ILMerge command line tool, see the above link. This approach works, but requires a little bit too much knowledge for the developers creating builds, therefor I have implemented a custom activity that wraps the use of ILMerge. This makes it much simpler to setup a new build definition and have the build automatically do the merging. The usage of the activity is then implemented as part of the Library Build process template mentioned in the previous post. For this article I have just created a simple build process template that only performs the ILMerge operation. Below is the code for the custom activity. To make it compile, you need to reference the ILMerge.exe assembly. /// <summary> /// Activity for merging a list of assembies into one, using ILMerge /// </summary> public sealed class ILMergeActivity : BaseCodeActivity { /// <summary> /// A list of file paths to the assemblies that should be merged /// </summary> [RequiredArgument] public InArgument<IEnumerable<string>> InputAssemblies { get; set; } /// <summary> /// Full path to the generated assembly /// </summary> [RequiredArgument] public InArgument<string> OutputFile { get; set; } /// <summary> /// Which input assembly that the attibutes for the generated assembly should be copied from. /// Optional. If not specified, the first input assembly will be used /// </summary> public InArgument<string> AttributeFile { get; set; } /// <summary> /// Kind of assembly to generate, dll or exe /// </summary> public InArgument<TargetKindEnum> TargetKind { get; set; } // If your activity returns a value, derive from CodeActivity<TResult> // and return the value from the Execute method. protected override void Execute(CodeActivityContext context) { string message = InputAssemblies.Get(context).Aggregate("", (current, assembly) => current + (assembly + " ")); TrackMessage(context, "Merging " + message + " into " + OutputFile.Get(context)); ILMerge m = new ILMerge(); m.SetInputAssemblies(InputAssemblies.Get(context).ToArray()); m.TargetKind = TargetKind.Get(context) == TargetKindEnum.Dll ? ILMerge.Kind.Dll : ILMerge.Kind.Exe; m.OutputFile = OutputFile.Get(context); m.AttributeFile = !String.IsNullOrEmpty(AttributeFile.Get(context)) ? AttributeFile.Get(context) : InputAssemblies.Get(context).First(); m.SetTargetPlatform(RuntimeEnvironment.GetSystemVersion().Substring(0,2), RuntimeEnvironment.GetRuntimeDirectory()); m.Merge(); TrackMessage(context, "Generated " + m.OutputFile); } } [Browsable(true)] public enum TargetKindEnum { Dll, Exe } NB: The activity inherits from a BaseCodeActivity class which is an internal helper class which contains some methods and properties useful for moste custom activities. In this case, it uses the TrackeMessage method for writing to the build log. You either need to remove the TrackMessage method calls, or implement this yourself (which is not very hard… ) The custom activity has the following input arguments: InputAssemblies A list with the (full) paths to the assemblies to merge OutputFile The name of the resulting merged assembly AttributeFile Which assembly to use as the template for the attribute of the merged assembly. This argument is optional and if left blank, the first assembly in the input list is used TargetKind Decides what type of assembly to create, can be either a dll or an exe Of course, there are more switches to the ILMerge.exe, and these can be exposed as input arguments as well if you need it. To show how the custom activity can be used, I have attached a build process template (see link at the top of this post) that merges the output of the projects being built (CommonLibrary.dll and CommonLibrary2.dll) into a merged assembly (NewLibrary.dll). The build process template has the following custom process parameters: The Assemblies To Merge argument is passed into a FindMatchingFiles activity to located all assemblies that are located in the BinariesDirectory folder after the compilation has been performed by Team Build. Here is the complete sequence of activities that performs the merge operation. It is located at the end of the Try, Compile, Test and Associate… sequence: It splits the AssembliesToMerge parameter and appends the full path (using the BinariesDirectory variable) and then enumerates the matching files using the FindMatchingFiles activity. When running the build, you can see that it merges two assemblies into a new one: And the merged assembly (and associated pdb file) is copied to the drop location together with the rest of the assemblies:

Using jQuery and OData to Insert a Database Record

- by Stephen Walther

In my previous blog entry, I explored two ways of inserting a database record using jQuery. We added a new Movie to the Movie database table by using a generic handler and by using a WCF service. In this blog entry, I want to take a brief look at how you can insert a database record using OData. Introduction to OData The Open Data Protocol (OData) was developed by Microsoft to be an open standard for communicating data across the Internet. Because the protocol is compatible with standards such as REST and JSON, the protocol is particularly well suited for Ajax. OData has undergone several name changes. It was previously referred to as Astoria and ADO.NET Data Services. OData is used by Sharepoint Server 2010, Azure Storage Services, Excel 2010, SQL Server 2008, and project code name “Dallas.” Because OData is being adopted as the public interface of so many important Microsoft technologies, it is a good protocol to learn. You can learn more about OData by visiting the following websites: http://www.odata.org http://msdn.microsoft.com/en-us/data/bb931106.aspx When using the .NET framework, you can easily expose database data through the OData protocol by creating a WCF Data Service. In this blog entry, I will create a WCF Data Service that exposes the Movie database table. Create the Database and Data Model The MoviesDB database is a simple database that contains the following Movies table: You need to create a data model to represent the MoviesDB database. In this blog entry, I use the ADO.NET Entity Framework to create my data model. However, WCF Data Services and OData are not tied to any particular OR/M framework such as the ADO.NET Entity Framework. For details on creating the Entity Framework data model for the MoviesDB database, see the previous blog entry. Create a WCF Data Service You create a new WCF Service by selecting the menu option Project, Add New Item and selecting the WCF Data Service item template (see Figure 1). Name the new WCF Data Service MovieService.svc. Figure 1 – Adding a WCF Data Service Listing 1 contains the default code that you get when you create a new WCF Data Service. There are two things that you need to modify. Listing 1 – New WCF Data Service File using System; using System.Collections.Generic; using System.Data.Services; using System.Data.Services.Common; using System.Linq; using System.ServiceModel.Web; using System.Web; namespace WebApplication1 { public class MovieService : DataService< /* TODO: put your data source class name here */ > { // This method is called only once to initialize service-wide policies. public static void InitializeService(DataServiceConfiguration config) { // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. // Examples: // config.SetEntitySetAccessRule("MyEntityset", EntitySetRights.AllRead); // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } First, you need to replace the comment /* TODO: put your data source class name here */ with a class that represents the data that you want to expose from the service. In our case, we need to replace the comment with a reference to the MoviesDBEntities class generated by the Entity Framework. Next, you need to configure the security for the WCF Data Service. By default, you cannot query or modify the movie data. We need to update the Entity Set Access Rule to enable us to insert a new database record. The updated MovieService.svc is contained in Listing 2: Listing 2 – MovieService.svc using System.Data.Services; using System.Data.Services.Common; namespace WebApplication1 { public class MovieService : DataService<MoviesDBEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("Movies", EntitySetRights.AllWrite); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } That’s all we have to do. We can now insert a new Movie into the Movies database table by posting a new Movie to the following URL: /MovieService.svc/Movies The request must be a POST request. The Movie must be represented as JSON. Using jQuery with OData The HTML page in Listing 3 illustrates how you can use jQuery to insert a new Movie into the Movies database table using the OData protocol. Listing 3 – Default.htm <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>jQuery OData Insert</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="Scripts/json2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input id="title" /> <br /> <label>Director:</label> <input id="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { // Convert the form into an object var data = { Title: $("#title").val(), Director: $("#director").val() }; // JSONify the data var data = JSON.stringify(data); // Post it $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "MovieService.svc/Movies", data: data, dataType: "json", success: insertCallback }); }); function insertCallback(result) { // unwrap result var newMovie = result["d"]; // Show primary key alert("Movie added with primary key " + newMovie.Id); } </script> </body> </html> jQuery does not include a JSON serializer. Therefore, we need to include the JSON2 library to serialize the new Movie that we wish to create. The Movie is serialized by calling the JSON.stringify() method: var data = JSON.stringify(data); You can download the JSON2 library from the following website: http://www.json.org/js.html The jQuery ajax() method is called to insert the new Movie. Notice that both the contentType and dataType are set to use JSON. The jQuery ajax() method is used to perform a POST operation against the URL MovieService.svc/Movies. Because the POST payload contains a JSON representation of a new Movie, a new Movie is added to the database table of Movies. When the POST completes successfully, the insertCallback() method is called. The new Movie is passed to this method. The method simply displays the primary key of the new Movie: Summary The OData protocol (and its enabling technology named WCF Data Services) works very nicely with Ajax. By creating a WCF Data Service, you can quickly expose your database data to an Ajax application by taking advantage of open standards such as REST, JSON, and OData. In the next blog entry, I want to take a closer look at how the OData protocol supports different methods of querying data.

Database users in the Oracle Utilities Application Framework

- by Anthony Shorten

I mentioned the product database users fleetingly in the last blog post and they deserve a better mention. This applies to all versions of the Oracle Utilities Application Framework. The Oracle Utilities Application Framework uses up to three users initially as part of the base operations of the product. The type of database supported (the framework supports Oracle, IBM DB2 and Microsoft SQL Server) dictates the number of users used and their permissions. For publishing brevity I will outline what is available for the Oracle database and, in summary, mention where it differs for the other database supported. For Oracle database customers we ship three distinct database users: Administration User (SPLADM or CISADM by default) - This is the database user that actually owns the schema. This user is not used by the product to do any DML (Data Manipulation Language) SQL other than that is necessary for maintenance of the database. This database user performs all the DCL (Data Control Language) and DDL (Data Definition Language) against the database. It is typically reserved for Database Administration use only. Product Read Write User (SPLUSER or CISUSER by default) - This is the database user used by the product itself to execute DML (Data Manipulation Language) statements against the schema owned by the Administration user. This user has the appropriate read and write permission to objects within the schema owned by the Administration user. For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. Product Read User (SPLREAD or CISREAD by default) - This is the database that has read only permission to the schema owned by the Administration user. It is used for reporting or any part of the product or interface that requires read permissions to the database (for example, products that have ConfigLab and Archiving use this user for remote access). For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. You may notice the words by default in the list above. The values supplied with the installer are the default and can be changed to what the site standard or implementation wants to use (as long as they conform to the standards supported by the underlying database). You can even create multiples of each within the same database and pointing to same schema. To manage the permissions for the users, there is a utility provided with the installation (oragensec (Oracle), db2gensec (DB2) or msqlgensec (SQL Server)) that generates the security definitions for the above users. That can be executed a number of times for each schema to give users appropriate permissions. For example, it is possible to define more than one read/write User to access the database. This is a common technique used by implementations to have a different user per access mode (to separate online and batch). In fact you can also allocate additional security (such as resource profiles in Oracle) to limit the impact of specific users at the database. To facilitate users and permissions, in Oracle for example, we create a CISREAD role (read only role) and a CISUSER role (read write role) that can be allocated to the appropriate database user. When the security permissions utility, oragensec in this case, is executed it uses the role to determine the permissions. To give you a case study, my underpowered laptop has multiple installations on it of multiple products but I have one database. I create a different schema for each product and each version (with my own naming convention to help me manage the databases). I create individual users on each schema and run oragensec to maintain the permissions for each appropriately. It works fine as long I have setup the userids appropriately. This means: Creating the users with the appropriate roles. I use the common CISUSER and CISREAD role across versions and across Oracle Utilities Application Framework products. Just remember to associate the CISUSER role with the database user you want to use for read/write operations and the CISREAD role with the user you wish to use for the read only operations. The role is treated as a tag to indicate the oragensec utility which appropriate permissions to assign to the user. The utilities for the other database types essentially do the same, obviously using the technology available within those databases. Run oragensec against the read write user and read only user against the appropriate administration user (I will abbreviate the user to ADM user). This ensures the right permissions are allocated to the right users for the right products. To help me there, I use the same prefix on the user name for the same product. For example, my Oracle Utilities Application Framework V4 environment has the administration user set to FW4ADM and the associated FW4USER and FW4READ as the users for the product to use. For my MWM environment I used MWMADM for the administration user and MWMUSER and MWMREAD for my associated users. You get the picture. When I run oragensec (once for each ADM user), I know what other users to associate with it. Remember to rerun oragensec against the users if I run upgrades, service packs or database based single fixes. This assures that the users are in synchronization with the ADM user. As a side note, for those who do not understand the difference between DML, DCL and DDL: DDL (Data Definition Language) - These are SQL statements that define the database schema and the structures within. SQL Statements such as CREATE and DROP are examples of DDL SQL statements. DCL (Data Control Language) - These are the SQL statements that define the database level permissions to DDL maintained objects within the database. SQL Statements such as GRANT and REVOKE are examples of DCL SQL statements. DML (Database Manipulation Language) - These are SQL statements that alter the data within the tables. SQL Statements such as SELECT, INSERT, UPDATE and DELETE are examples of DML SQL statements. Hope this has clarified the database user support. Remember in Oracle Utilities Application Framework V4 we enhanced this by also supporting CLIENT_IDENTIFIER to allow the database to still use the administration user for the main processing but make the database session more traceable.

SQLAuthority News – Memories at Anniversary of SQL Wait Stats Book

- by pinaldave

SQL Wait Stats About a year ago, I had very proud moment. I had published my second book SQL Server Wait Stats with me as a primary author. It has been a long journey since then. The book got great response and it was widely accepted in the community. It was first of its kind of book written specifically on Wait Stats and Performance. The book was based on my earlier month long series written on the same subject SQL Server Wait Stats. Today, on the anniversary of the book, lots of things come to my mind let me share a few here. Idea behind Blog Series A very common question I often receive is why I wrote a 30 day series on Wait Stats. There were two reasons for it. 1) I have been working with SQL Server for a long time and have troubleshoot more than hundreds of SQL Server which are related to performance tuning. It was a great experience and it taught me a lot of new things. I always documented my experience. After a while I found that I was able to completely rely on my own notes when I was troubleshooting any servers. It is right then I decided to document my experience for the community. 2) While working with wait stats there were a few things, which I thought I knew it well as they were working. However, there was always a fear in the back of mind that what happens if what I believed was incorrect and I was on the wrong path all the time. There was only one way to get it validated. Put it out in front community with my understanding and request further help to improve my understanding. It worked, it worked beautifully. I received plenty of conversations, emails and comments. I refined my content based on various conversations and make it more relevant and near accurate. I guess above two are the major reasons for beginning my journey on writing Wait Stats blog series. Idea behind Book After writing a blog series there was a good amount of request I keep on receiving that I should convert it to eBook or proper book as reading blog posts is great but it goes not give a comprehensive understanding of the subject. The very common feedback from users who were beginning the subject that they will prefer to read it in a structured method. After hearing the feedback for more than 4 months, I decided to write a book based on the blog posts. When I envisioned book, I wanted to make sure this book addresses the wait stats concepts from the fundamentals and fill the gaps of blogs I wrote earlier. Rick Morelan and Joes 2 Pros Team I must acknowledge my co-author Rick Morelan for his unconditional support in writing this book. I had already authored one book before I published this book. The experience to write the book was out of the world. Writing blog posts are much much easier than writing books. The efforts it takes to write a book is 100 times more even though the content is ready. I could have not done it myself if there was not tremendous support of my co-author and editor’s team. We spend days and days researching and discussing various concepts covered in the book. When we were in doubt we reached out to experts as well did a practical reproduction of the scenarios to validate the concepts and claims. After continuous 3 months of hard work we were able to get this book out in the community. September 1st – the lucky day Well, we had to select any day to publish the books. When book was completed in August last week we felt very glad. We all had worked hard and having a sample draft book in hand was feeling like having a newborn baby in our hand. Every time my books are published I feel the same joy which I had when my daughter was born. The feeling of holding a new book in hand is the (almost) same feeling as holding newborn baby. I am excited. For me September 1st has been the luckiest day in mind life. My daughter Shaivi was born on September 1st. Since then every September first has been excellent day and have taken me to the next step in life. I believe anything and everything I do on September 1st it is turning out to be successful and blessed. Rick and I had finished a book in the last week of August. We sent it to the publisher (printer) and asked him to take the book live as soon as possible. We did not decide on any date as we wanted the book to get out as fast as it can. Interesting enough, the publisher/printer selected September 1st for publishing the book. He published the book on 1st September and I knew it at the same time that this book will go next level. Book Model – The Most Beautiful Girl We were done with book. We had no budget left for marketing. Rick and I had a long conversation regarding how to spread the words for the book so it can reach to many people. While we were talking about marketing Rick come up with the idea that we should hire a most beautiful girl around who acknowledge our book and genuinely care for book. It was a difficult task and Rick asked me to find a more beautiful girl. I am a father and the most beautiful girl for me my daughter. This was not a difficult task for me. Rick had given me task to find the most beautiful girl and I just could not think of anyone else than my own daughter. I still do not know what Rick thought about this idea but I had already made up my mind. You can see the detailed blog post here. The Fun Experiments Book Signing Event We had lots of fun moments along this book. We have given away more books to people for free than we have sold them actually. We had done book signing events, contests, and just plain give away when we found people can be benefited from this book. There was never an intention to make money and get rich. We just wanted that more and more people know about this new concept and learn from it. Today when I look back to the earnings there is nothing much we have earned if you talk about dollars. However the best reward which we have received is the satisfaction and love of community. The amount of emails, conversations we have so far received for this book is over thousands. We had fun writing this book, it was indeed a very satisfying journey. I have earned lots of friends while learning and exploring. Availability The book is one year old but still very relevant when it is about performance tuning. It is available at various online book stores. If you have read the book, do let me know what you think of it.

Enhanced REST Support in Oracle Service Bus 11gR1

- by jeff.x.davies

In a previous entry on REST and Oracle Service Bus (see http://blogs.oracle.com/jeffdavies/2009/06/restful_services_with_oracle_s_1.html) I encoded the REST query string really as part of the relative URL. For example, consider the following URI: http://localhost:7001/SimpleREST/Products/id=1234 Now, technically there is nothing wrong with this approach. However, it is generally more common to encode the search parameters into the query string. Take a look at the following URI that shows this principle http://localhost:7001/SimpleREST/Products?id=1234 At first blush this appears to be a trivial change. However, this approach is more intuitive, especially if you are passing in multiple parameters. For example: http://localhost:7001/SimpleREST/Products?cat=electronics&subcat=television&mfg=sony The above URI is obviously used to retrieve a list of televisions made by Sony. In prior versions of OSB (before 11gR1PS3), parsing the query string of a URI was more difficult than in the current release. In 11gR1PS3 it is now much easier to parse the query strings, which in turn makes developing REST services in OSB even easier. In this blog entry, we will re-implement the REST-ful Products services using query strings for passing parameter information. Lets begin with the implementation of the Products REST service. This service is implemented in the Products.proxy file of the project. Lets begin with the overall structure of the service, as shown in the following screenshot. This is a common pattern for REST services in the Oracle Service Bus. You implement different flows for each of the HTTP verbs that you want your service to support. Lets take a look at how the GET verb is implemented. This is the path that is taken of you were to point your browser to: http://localhost:7001/SimpleREST/Products/id=1234 There is an Assign action in the request pipeline that shows how to extract a query parameter. Here is the expression that is used to extract the id parameter: $inbound/ctx:transport/ctx:request/http:query-parameters/http:parameter[@name="id"]/@value The Assign action that stores the value into an OSB variable named id. Using this type of XPath statement you can query for any variables by name, without regard to their order in the parameter list. The Log statement is there simply to provided some debugging info in the OSB server console. The response pipeline contains a Replace action that constructs the response document for our rest service. Most of the response data is static, but the ID field that is returned is set based upon the query-parameter that was passed into the REST proxy. Testing the REST service with a browser is very simple. Just point it to the URL I showed you earlier. However, the browser is really only good for testing simple GET services. The OSB Test Console provides a much more robust environment for testing REST services, no matter which HTTP verb is used. Lets see how to use the Test Console to test this GET service. Open the OSB we console (http://localhost:7001/sbconsole) and log in as the administrator. Click on the Test Console icon (the little "bug") next to the Products proxy service in the SimpleREST project. This will bring up the Test Console browser window. Unlike SOAP services, we don't need to do much work in the request document because all of our request information will be encoded into the URI of the service itself. Belore the Request Document section of the Test Console is the Transport section. Expand that section and modify the query-parameters and http-method fields as shown in the next screenshot. By default, the query-parameters field will have the tags already defined. You just need to add a tag for each parameter you want to pass into the service. For out purposes with this particular call, you'd set the quer-parameters field as follows: <tp:parameter name="id" value="1234" /> </tp:query-parameters> Now you are ready to push the Execute button to see the results of the call. That covers the process for parsing query parameters using OSB. However, what if you have an OSB proxy service that needs to consume a REST-ful service? How do you tell OSB to pass the query parameters to the external service? In the sample code you will see a 2nd proxy service called CallREST. It invokes the Products proxy service in exactly the same way it would invoke any REST service. Our CallREST proxy service is defined as a SOAP service. This help to demonstrate OSBs ability to mediate between service consumers and service providers, decreasing the level of coupling between them. If you examine the message flow for the CallREST proxy service, you'll see that it uses an Operational branch to isolate processing logic for each operation that is defined by the SOAP service. We will focus on the getProductDetail branch, that calls the Products REST service using the HTTP GET verb. Expand the getProduct pipeline and the stage node that it contains. There is a single Assign statement that simply extracts the productID from the SOA request and stores it in a local OSB variable. Nothing suprising here. The real work (and the real learning) occurs in the Route node below the pipeline. The first thing to learn is that you need to use a route node when calling REST services, not a Service Callout or a Publish action. That's because only the Routing action has access to the $oubound variable, especially when invoking a business service. The Routing action contains 3 Insert actions. The first Insert action shows how to specify the HTTP verb as a GET. The second insert action simply inserts the XML node into the request. This element does not exist in the request by default, so we need to add it manually. Now that we have the element defined in our outbound request, we can fill it with the parameters that we want to send to the REST service. In the following screenshot you can see how we define the id parameter based on the productID value we extracted earlier from the SOAP request document. That expression will look for the parameter that has the name id and extract its value. That's all there is to it. You now know how to take full advantage of the query parameter parsing capability of the Oracle Service Bus 11gR1PS2. Download the sample source code here: rest2_sbconfig.jar Ubuntu and the OSB Test Console You will get an error when you try to use the Test Console with the Oracle Service Bus, using Ubuntu (or likely a number of other Linux distros also). The error (shown below) will state that the Test Console service is not running. The fix for this problem is quite simple. Open up the WebLogic Server administrator console (usually running at http://localhost:7001/console). In the Domain Structure window on the left side of the console, select the Servers entry under the Environment heading. The select the Admin Server entry in the main window of the console. By default, you should be viewing the Configuration tabe and the General sub tab in the main window. Look for the Listen Address field. By default it is blank, which means it is listening on all interfaces. For some reason Ubuntu doesn't like this. So enter a value like localhost or the specific IP address or DNS name for your server (usually its just localhost in development envirionments). Save your changes and restart the server. Your Test Console will now work correctly.

Using Teleriks new LINQ implementation to create OData feeds

This week Telerik released a new LINQ implementation that is simple to use and produces domain models very fast. Built on top of the enterprise grade OpenAccess ORM, you can connect to any database that OpenAccess can connect to such as: SQL Server, MySQL, Oracle, SQL Azure, VistaDB, etc. While this is a separate LINQ implementation from traditional OpenAccess Entites, you can use the visual designer without ever interacting with OpenAccess, however, you can always hook into the advanced ORM features like caching, fetch plan optimization, etc, if needed. Just to show off how easy our LINQ implementation is to use, I will walk you through building an OData feed using Data Services Update for .NET Framework 3.5 SP1. (Memo to Microsoft: P-L-E-A-S-E hire someone from Apple to name your products.) How easy is it? If you have a fast machine, are skilled with the mouse, and type fast, you can do this in about 60 seconds via three easy steps. (I promise in about 2-3 weeks that you can do this in less then 30 seconds. Stay tuned for that.) Step 1 (15-20 seconds): Building your Domain Model In your web project in Visual Studio, right click on the project and select Add|New Item and select Telerik OpenAccess Domain Model as your item template. Give the file a meaningful name as well. Select your database type (SQL Server, SQL Azure, Oracle, MySQL, VistaDB, etc) and build the connection string. If you already have a Visual Studio connection string already saved, this step is trivial. Then select your tables, enter a name for your model and click Finish. In this case I connected to Northwind and selected only Customers, Orders, and Order Details. I named my model NorthwindEntities and will use that in my DataService. Step 2 (20-25 seconds): Adding and Configuring your Data Service In your web project in Visual Studio, right click on the project and select Add|New Item and select ADO .NET Data Service as your item template and name your service. In the code behind for your Data Service you have to make three small changes. Add the name of your Telerik Domain Model (entered in Step 1) as the DataService name (shown on line 6 below as NorthwindEntities) and uncomment line 11 and add a * to show all entities. Optionally if you want to take advantage of the DataService 3.5 updates, add line 13 (and change IDataServiceConfiguration to DataServiceConfiguration in line 9.) 1: using System.Data.Services; 2: using System.Data.Services.Common; 3: 4: namespace Telerik.RLINQ.Astoria.Web 5: { 6: public class NorthwindService : DataService<NorthwindEntities> 7: { 8: //change the IDataServiceConfigurationto DataServiceConfiguration 9: public static void InitializeService(DataServiceConfiguration config) 10: { 11: config.SetEntitySetAccessRule("*", EntitySetRights.All); 12: //take advantage of the "Astoria3.5 Update" features 13: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 14: } 15: } 16: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Step 3 (~30 seconds): Adding the DataServiceKeys You now have to tell your data service what are the primary keys of each entity. To do this you have to create a new code file and create a few partial classes. If you type fast, use copy and paste from your first entity, and use a refactoring productivity tool, you can add these 6-8 lines of code or so in about 30 seconds. This is the most tedious step, but dont worry, Ive bribed some of the developers and our next update will eliminate this step completely. Just create a partial class for each entity you have mapped and add the attribute [DataServiceKey] on top of it along with the keys field name. If you have any complex properties, you will need to make them a primitive type, as I do in line 15. Create this as a separate file, dont manipulate the generated data access classes in case you want to regenerate them again later (even thought that would be much faster.) 1: using System.Data.Services.Common; 2: 3: namespace Telerik.RLINQ.Astoria.Web 4: { 5: [DataServiceKey("CustomerID")] 6: public partial class Customer 7: { 8: } 9: 10: [DataServiceKey("OrderID")] 11: public partial class Order 12: { 13: } 14: 15: [DataServiceKey(new string[] { "OrderID", "ProductID" })] 16: public partial class OrderDetail 17: { 18: } 19: 20: } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Done! Time to run the service. Now, lets run the service! Select the svc file and right click and say View in Browser. You will see your OData service and can interact with it in the browser. Now that you have an OData service set up, you can consume it in one of the many ways that OData is consumed: using LINQ, the Silverlight OData client, Excel PowerPivot, or PhP, etc. Happy Data Servicing!

We already have over 80 articles in several categories including Silverlight. Take a look: here.

You are probably NOT a SharePoint Development Expert if…

- by Mark Rackley

So, all you aspiring SharePoint experts out there (especially those of you who put “expert” in your resumes). It’s time for a cold cool splash of reality. More than likely you are NOT an expert (I know I’m not). Yes, you may have some expertise in certain aspects in SharePoint (it’s questionable if I have THAT some days), but make sure you’ve got the basics down before you start throwing that word “expert” around. I know that it becomes frustrating to those looking to hire SharePoint people and having to sift through all the resumes of those who think very highly of themselves and their skills only to find those gaping holes in common best practices. I’m much more willing to hire a decent dev who KNOWS they are not an expert than to hire a decent+ dev who THINKS they are an expert. So… I’ve compiled a small reality check for you SharePoint Devs. and a “red flag” check for those of you wishing to hire a SharePoint developer. If any of these apply to you, you are probably not a SharePoint Development Expert. You are not a SharePoint Development Expert if you manually copy your DLLs Seriously, I don’t care if you write the best code in the world. If you are manually copying files to each web front end you are NOT a SharePoint Development expert. Yes, I realize the admins are generally the ones who do the actual deployments, but if you don’t know how to create solution packages for your admins, you are going to end up doing more damage than good some day. There are TONS of tools out there to help generate deployable solutions for you. You have ZERO excuse. You are not a SharePoint Development expert if you can’t tell me the main artifacts of a solution package Directly related to the first one. If you don’t know what the Manifest, DDF, WSP, and Feature files are and how they are used in a solution package, you are NOT a SharePoint development expert. I’m not asking you to be able to write them all from scratch (heck, I can’t even do that), but you MUST know what they are and how to tweak them if necessary. You are not a SharePoint Development expert if you don’t know what a Content Type or a Site Column is You would be absolutely amazed at how many “Expert” SharePoint Developers have NEVER EVER created a Content Type or Site Column or even know what they are. I mean, why would you ever want to create those when you can just do everything as a custom list or custom field? right???? (that’s sarcasm). You also need to know how to package a Content Type and a Site Column into a deployable package by the way. You are not a SharePoint Development expert if you have not created at least one Web Part, Workflow, Timer Job, and Event Handler. If you haven’t written at least one of each, you don’t fully understand what they do or their limitations. Again, I expect NO ONE to be able to write these things blind. I think the last time I wrote an application from scratch without copying and pasting from another project I had done before was back in 1994? Seriously, coding is like a Sour Dough starter, you get it from someone else and keep adding to it. You are not a SharePoint Development expert if you don’t know how to properly dispose of objects Another biggie with zero excuse for getting it wrong. It is so well known that you must dispose of your SPWeb and SPSite objects that if you aren’t doing it then you are not an expert. Heck, if you utilize “using” when handling SPWeb and SPSite objects and don’t realize that it disposes of those objects for you, then you are not a SharePoint Development expert. You are not a SharePoint Development expert if you do not know how to properly elevate privileges Just one of those development basics that any decent SharePoint Developer has got to have down and understand how and why it’s used You are not a SharePoint Development expert if you don’t know all of the development options available to SharePoint and when they should be used Okay… so all you hard core .NET SharePoint dev geeks take a moment to listen. You may be the most top not SharePoint .NET developer in the world, but if you are opening Visual Studio to solve every problem in SharePoint, then you are NOT a SharePoint development expert. The SharePoint developer’s tool kit is growing every day with tools like Visual Studio, Data View Web Parts, XSL, jQuery, SPServices, etc. etc… If you don’t have the ability to at least recognize that “hey, you can basically do the same thing here but just dropping in Easy Tabs instead of writing some weird web part” then you are NOT a SharePoint Development expert AND you are doing a huge disservice to your clients and customers. You are probably NOT a SharePoint Development expert if you call yourself an Expert So, truth telling time. I’m not an expert. There, I said it. I feel so much better. Now, I realize the word “expert” has been used with my name before, but I am quick to point out that I KNOW the experts and know that they will help me if I need it, but I’m not an expert in all things SharePoint. The minute you take on that moniker you are setting yourself up for a fall. It’s too big, there’s too much to know, and there’s WAY too much you can do wrong. You are not a SharePoint Development expert if you are not involved in the community I expect to get the most flack for this one, but it’s always a huge red flag for me when someone says they are an expert and has ZERO knowledge of the SharePoint community. The SharePoint community is ABSOLUTELY CRITICAL to be an effective SharePoint developer, admin, architect, power user or whatever the heck you are!! The community keeps you sane, tells you when you are NOT using a best practice, recommends the best practice, and even knows when Microsoft is giving you the wrong information (*gasp* it does happen). If you can’t tell me who you are following on twitter, who's blog you read, what conferences you attend, or name the experts who you monitor to make sure you are not doing something stupid, then you are probably doing something stupid. Again, not asking you to be a speaker, blogger, or the least bit extroverted but you should be at LEAST stalking the experts. So… what’s the point? So… yeah… what’s my point in all this. Well, first of all let me point out that this is by far not a finished list and I could come up with a LOT more specific “deep dive” questions, but these should be high enough level that even non experts can recognize and ask them. If you have some common ones you run into let me know and add them in the comments below. Also, keep in mind I’m not saying you as a developer HAVE to know EVERYTHING, but you DO need to know what you don’t know and proudly and honestly state “I don’t know, but I’ll learn and find out”. Those of us hiring SharePoint developers and know and have a passion for SharePoint are not looking for that elusive “expert” who knows everything. We are looking for someone who “gets it”, has a similar passion, great attitude, an understanding that they DON’T know everything, and a desire to do it right. I would bet money that most SharePoint development disasters happen because of “experts” who think they know everything rather than the developer who is cautious and knows he doesn’t. Lastly, I know there’s a raging debate over what a “SharePoint Developer” is (I should know, as I keep bringing it up). So, obviously this blog post is more closely tied to the .NET side of SharePoint development and less towards the client side, middle tier, or whatever you want to call it. So, let’s please not get that argument going here as well… Thanks

Use Those Extra Mouse Buttons to Increase Efficiency

- by Mark Virtue

Did you know that the most commonly used mouse actions are clicking a window’s “Close” button (the X in the top-right corner), and clicking the “Back” button (in a browser and various other programs)? How much time do you spend every day locating the Close button or the Back button with your mouse so that you can click on them? And what about that mouse you’re using – how many buttons does it have, besides the two main ones? Most mouses these days have at least four (including the scroll-wheel, which a lot of people don’t realize is also a button as well). Why not assign those extra buttons to your most common mouse actions, and save yourself a bundle of mousing-around time every day? If your mouse was manufactured by one of the “premium” mouse manufacturers (Microsoft, Logitech, etc), it almost certain came with driver software to allow you to customize your mouse’s controls and take advantage of your mouse’s special features. Microsoft, for example, provides driver software called IntelliPoint (link below), while Logitech provides SetPoint. It’s possible that your mouse has some extra buttons but doesn’t come with its own driver software (the author is using a Microsoft Bluetooth Notebook Mouse 5000, which amazingly is not supported by the Microsoft IntelliPoint software!). If your mouse falls into this category, you can use a marvelous free product called X-Mouse Button Control, from Highresolution Enterprises (link below). It provides a truly amazing array of mouse configuration options, including assigning actions to buttons on a per-application basis. Once X-Mouse Button Control is downloaded, its setup process is quite straightforward. Once downloaded, you can start the program via Start / Highresolution Enterprises / X-Mouse Button Control. You will find the program’s icon in the system tray: Right-click on the icon and select Setup from the pop-up menu. The program’s configuration window appears: It’s extremely unlikely that we will want to change the functionality of our mouse’s two main buttons (left and right), so instead we’ll look at the rest of the options on the right side of the window. The Middle Button refers to either the third, middle button (found on some old mouses), or the pressing of the wheel itself, as a button (if you didn’t know you could press your wheel like a button, try it out now). Mouse Button 4 and Mouse Button 5 usually refer to the extra buttons found on the side of the mouse, often near your thumb. So what can we use these extra mouse buttons for? Well, clearly Close and Back are two obvious candidates. Each of these can be found by selecting them from the drop-down menu next to each button field: Once the two options are chosen, the window will look something like this: If you’re not interested in choosing Back or Close, you may like to try some of the other options in the list, including: Cut, Copy and Paste Undo Show the Desktop Next/Previous track (for media playback) Open any program Simulate any keystroke or combination of keystrokes ….and many other options. Explore the drop-down list to see them all. You may decide, for example, that closing the current document (as opposed to the current program) would be a good use for Mouse Button 5. In other words, we need to simulate the keypress of Ctrl-F4. Let’s see how we achieve this. First we select Simulated Keystrokes from the drop-down list: The Simulated Keystrokes window opens: The instructions on the page are pretty comprehensive. If you want to simulate the Ctrl-F4 keystroke, you need to type {CTRL}{F4} into the box: …and then click OK. Assigning Actions to Buttons on a Per-Application Basis One of the most powerful features of X-Mouse Button Control is the ability to assign actions to buttons on a per-application basis. This means that if we have a particular program open, then our mouse will behave differently – our buttons will do different things. For example, when we have Windows Media Player open, for example, we may wish to have buttons assigned to Play/Pause, Next track and Previous track, as well as changing the volume with the mouse! This is easy with X-Mouse Button Control. We start by opening Windows Media Player. This makes the next step easier. Then we return to X-Mouse Button Control and add a new “configuration”. This is done by clicking the Add button: A window opens containing a list of all running programs, including our recently opened Windows Media Player: We select Windows Media Player and click OK. A new, blank “configuration” is created: We repeat the earlier steps to assign buttons to Play/Pause, Next track and Previous track, and assign scrolling the wheel to alter the volume: To save all our changes and close the window, we click Apply. Now spend a few minutes thinking of all the applications you use the most, and what are the most common simple tasks you perform in each of those applications. Those tasks are then perfect candidates for per-application button assignments. There are many more configuration options and capabilities of X-Mouse Button Control – too many to list here. We encourage you to spend a bit of time exploring the Setup window. Then, most important of all, don’t forget to use your new mouse buttons! Get into the habit of using them, and then after a while you’ll start to wonder how you ever tolerated the laborious, tedious, time-consuming process of actually locating each window’s Close button… Download X-Mouse Button Control Highresolution Enterprise Similar Articles Productive Geek Tips Add Specialized Toolbar Buttons to Firefox the Easy WayBoost Your Mouse Pointing Accuracy in WindowsMake Mouse Navigation Faster in WindowsVista Style Popup Previews for Firefox TabsStupid Geek Tricks: Using the Quick Zoom Feature in Outlook TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 Download Videos from Hulu Pixels invade Manhattan Convert PDF files to ePub to read on your iPad Hide Your Confidential Files Inside Images Get Wildlife Photography Tips at BBC’s PhotoMasterClasses Mashpedia is a Real-time Encyclopedia

LightDM will not start after stopping it

- by Sweeters

I am running Ubuntu 11.10 "Oneiric Ocelot", and in trying to install the nvidia CUDA developer drivers I switched to a virtual terminal (Ctrl-Alt-F5) and stopped lightdm (installation required that no X server instance be running) through sudo service lightdm stop. Re-starting lightdm with sudo service lightdm start did not work: A couple of * Starting [...] lines where displayed, but the process hanged. (I do not remember at which point, but I think it was * Starting System V runlevel compatibility. I manually rebooted my laptop, and ever since booting seems to hang, usually around the * Starting anac(h)ronistic cron [OK] log line (not consistently at that point, though). From that point on, I seem to be able to interact with my system only through a tty session (Ctrl-Alt-F1). I've tried purging and reinstalling both lightdm and gdm, as well as selecting both as the default display managers (through sudo dpkg-reconfigure [lightdm / gdm] or by manually editing /etc/X11/default-display-manager) through both apt-get and aptitude (that shouldn't make a difference anyway) after updating the packages, but the problem persists. Some of the responses I'm getting are the following: After running sudo dpkg-reconfigure lightdm (but not ... gdm) I get the following message: dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_NAME missing dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_PACKAGE missing After trying sudo service lightdm start or sudo start lightdm I get to see the boot loading screen again but nothing changes. If I go back to the tty shell I see lightdm start/running, process <num> but ps -e | grep lightdm gives no output. After trying sudo service gdm start or sudo starg gdm I get the gdm start/running, process <num> message, and gdm-binary is supposedly an active process, but all that happens is that the screen blinks a couple of times and nothing else. Other candidate solutions that I'd found on the web included running startx but when I try that I get an error output [...] Fatal server error: no screens found [...]. Moreover, I made sure that lightdm-gtk-greeter is installed but that did not help either. Please excuse my not including complete outputs/logs; I am writing this post from another computer and it's hard to manually copy the complete logs. Also, I've seen several posts that had to do with similar problems, but either there was no fix, or the one suggested did not work for me. In closing: Please help! I very much hope to avoid re-installing Ubuntu from scratch! :) Alex @mosi I did not manage to fix the NVIDIA kernel driver as per your instructions. I should perhaps mention that I'm on a Dell XPS15 laptop with an NVIDIA Optimus graphics card, and that I have bumblebee installed (which installs nvidia drivers during its installation, I believe).

Simple way of converting server side objects into client side using JSON serialization for asp.net websites

- by anil.kasalanati

Introduction:- With the growth of Web2.0 and the need for faster user experience the spotlight has shifted onto javascript based applications built using REST pattern or asp.net AJAX Pagerequest manager. And when we are working with javascript wouldn’t it be much better if we could create objects in an OOAD way and easily push it to the client side. Following are the reasons why you would push the server side objects onto client side - Easy availability of the complex object. - Use C# compiler and rick intellisense to create and maintain the objects but use them in the javascript. You could run code analysis etc. - Reduce the number of calls we make to the server side by loading data on the pageload. I would like to explain about the 3rd point because that proved to be highly beneficial to me when I was fixing the performance issues of a major website. There could be a scenario where in you be making multiple AJAX based webrequestmanager calls in order to get the same response in a single page. This happens in the case of widget based framework when all the widgets are independent but they need some common information available in the framework to load the data. So instead of making n multiple calls we could load the data needed during pageload. The above picture shows the scenario where in all the widgets need the common information and then call GetData webservice on the server side. Ofcourse the result can be cached on the client side but a better solution would be to avoid the call completely. In order to do that we need to JSONSerialize the content and send it in the DOM. Example:- I have developed a simple application to demonstrate the idea and I would explaining that in detail here. The class called SimpleClass would be sent as serialized JSON to the client side . And this inherits from the base class which has the implementation for the GetJSONString method. You can create a single base class and all the object which need to be pushed to the client side can inherit from that class. The important thing to note is that the class should be annotated with DataContract attribute and the methods should have the Data Member attribute. This is needed by the .Net DataContractSerializer and this follows the opt-in mode so if you want to send an attribute to the client side then you need to annotate the DataMember attribute. So if I didn’t want to send the Result I would simple remove the DataMember attribute. This is default WCF/.Net 3.5 stuff but it provides the flexibility of have a fullfledged object on the server side but sending a smaller object to the client side. Sometimes you may hide some values due to security constraints. And thing you will notice is that I have marked the class as Serializable so that it can be stored in the Session and used in webfarm deployment scenarios. Following is the implementation of the base class – This implements the default DataContractJsonSerializer and for more information or customization refer to following blogs – http://softcero.blogspot.com/2010/03/optimizing-net-json-serializing-and-ii.html http://weblogs.asp.net/gunnarpeipman/archive/2010/12/28/asp-net-serializing-and-deserializing-json-objects.aspx The next part is pretty simple, I just need to inject this object into the aspx page. And in the aspx markup I have the following line – <script type="text/javascript"> var data =(<%=SimpleClassJSON %>); alert(data.ResultText); </script> This will output the content as JSON into the variable data and this can be any element in the DOM. And you can verify the element by checking data in the Firebug console. Design Consideration – If you have a lot of javascripts then you need to think about using Script # and you can write javascript in C#. Refer to Nikhil’s blog – http://projects.nikhilk.net/ScriptSharp Ensure that you are taking security into consideration while exposing server side objects on to client side. I have seen application exposing passwords, secret key so it is not a good practice. The application can be tested using the following url – http://techconsulting.vpscustomer.com/Samples/JsonTest.aspx The source code is available at http://techconsulting.vpscustomer.com/Source/HistoryTest.zip

Portal And Content - Content Integration - Best Practices

- by Stefan Krantz

Lately we have seen an increase in projects that have failed to either get user friendly content integration or non satisfactory performance. Our intention is to mitigate any knowledge gap that our previous post might have left you with, therefore this post will repeat some recommendation or reference back to old useful post. Moreover this post will help you understand ground up how to design, architect and implement business enabled, responsive and performing portals with complex requirements on business centric information publishing. Design the Information Model The key to successful portal deployments is Information modeling, it's a key task to understand the use case you designing for, therefore I have designed a set of question you need to ask yourself or your customer: Question: Who will own the content, IT or Business? Answer: BusinessQuestion: Who will publish the content, IT or Business? Answer: BusinessQuestion: Will there be multiple publishers? Answer: YesQuestion: Are the publishers computer scientist?Answer: NoQuestion: How often do the information changes, daily, weekly, monthly?Answer: Daily, weekly If your answers to the questions matches at least 2, we strongly recommend you design your content with following principles: Divide your pages in to logical sections, where each section is marked with its purpose Assign capabilities to each section, does it contain text, images, formatting and/or is it static and is populated through other contextual information Select editor/design element type WYSIWYG - Rich Text Plain Text - non-format text Image - Image object Static List - static list of formatted informationDynamic Data List - assembled information from multiple data files through CMIS query The result of such design map could look like following below examples: Based on the outcome of the required elements in the design column 3 from the left you will now simply design a data model in WebCenter Content - Site Studio by creating a Region Definition structure matching your design requirements.For more information on how to create a Region definition see following post: Region Definition Post - note see instruction 7 for details. Each region definition can now be used to instantiate data files, a data file will hold the actual data for each element in the region definition. Another way you can see this is to compare the region definition as an extension to the metadata model in WebCenter Content for each data file item. Design content templates With a solid dependable information model we can now proceed to template creation and page design, in this phase focuses on how to place the content sections from the region definition on the page via a Content Presenter template. Remember by creating content presenter templates you will leverage the latest and most integrated technology WebCenter has to offer. This phase is much easier since the you already have the information model and design wire-frames to base the logic on, however there is still few considerations to pay attention to: Base the template on ADF and make only necessary exceptions to markup when required Leverage ADF design components for Tabs, Accordions and other similar components, this way the design in the content published areas will comply with other design areas based on custom ADF taskflows There is no performance impact when using meta data or region definition based data All data access regardless of type, metadata or xml data it can be accessed via the Content Presenter - Node. See below for applied examples on how to access data Access metadata property from Document - #{node.propertyMap['myProp'].value}myProp in this example can be for instance (dDocName, dDocTitle, xComments or any other available metadata) Access element data from data file xml - #{node.propertyMap['[Region Definition Name]:[Element name]'].asTextHtml}Region Definition Name is the expect region definition that the current data file is instantiatingElement name is the element value you like to grab from the data file I recommend you read following useful post on content template topic:CMIS queries and template creation - note see instruction 9 for detailsStatic List template rendering For more information on templates:Single Item Content TemplateMulti Item Content TemplateExpression Language Internationalization Considerations When integrating content assets via content presenter you by now probably understand that the content item/data file is wired to the page, what is also pretty common at this stage is that the content item/data file only support one language since its not practical or business friendly to mix that into a complex structure. Therefore you will be left with a very common dilemma that you will have to either build a complete new portal for each locale, which is not an good option! However with little bit of information modeling and clear naming convention this can be addressed. Basically you can simply make sure that all content item/data file are named with a predictable naming convention like "Content1_EN" for the English rendition and "Content1_ES" for the Spanish rendition. This way through simple none complex customizations you will be able to dynamically switch the actual content item/data file just before rendering. By following proposed approach above you not only enable a simple mechanism for internationalized content you also preserve the functionality in the content presenter to support business accessible run-time publishing of information on existing and new pages. I recommend you read following useful post on Internationalization topics:Internationalize with Content Presenter Integrate with Review & Approval processes Today the Review and approval functionality and configuration is based out of WebCenter Content - Criteria Workflows. Criteria Workflows uses the metadata of the checked in document to evaluate if the document is under any review/approval process. So for instance if a Criteria Workflow is configured to force any documents with Version = "2" or "higher" and Content Type is "Instructions", any matching content item version on check in will now enter the workflow before getting released for general access. Few things to consider when configuring Criteria Workflows: Make sure to not trigger on version one for Content Items that are Data Files - if you trigger on version 1 you will not only approve an empty document you will also have a content presenter pointing to a none existing document - since the document will only be available after successful completion of the workflow Approval workflows sometimes requires more complex criteria, the recommendation if that is the case is that the meta data triggering such criteria is automatically populated, this can be achieved through many approaches including Content Profiles Criteria workflows are configured and managed in WebCenter Content Administration Applets where you can configure one or more workflows. When you configured Criteria workflows the Content Presenter will support the editors with the approval process directly inline in the "Contribution mode" of the portal. In addition to approve/reject and details of the task, the content presenter natively support the user to view the current and future version of the change he/she is approving. See below for example: Architectural recommendation To support review&approval processes - minimize the amount of data files per page Each CMIS query can consume significant time depending on the complexity of the query - minimize the amount of CMIS queries per page Use Content Presenter Templates based on ADF - this way you minimize the design considerations and optimize the usage of caching Implement the page in as few Data files as possible - simplifies publishing process, increases performance and simplifies release process Named data file (node) or list of named nodes when integrating to pages increases performance vs. querying for data Named data file (node) or list of named nodes when integrating to pages enables business centric page creation and publishing and reduces the need for IT department interaction Summary Just because one architectural decision solves a business problem it doesn't mean its the right one, when designing portals all architecture has to be in harmony and not impacting each other. For instance the most technical complex solution is not always the best since it will most likely defeat the business accessibility, performance or both, therefore the best approach is to first design for simplicity that even a non-technical user can operate, after that consider the performance impact and final look at the technology challenges these brings and workaround them first with out-of-the-box features, after that design and develop functions to complement the short comings.
