Cloud, automation drive new growth in SOA governance market | ZDNet "SOA governance tools and processes learned over the past decade are now underpinning cloud projects as they scale across enterprises," reports Joe McKendrick. But there remains a lack of understanding about SOA Governance. DevOps Basics: Track Down High CPU Thread with ps, top and the new JDK7 jcmd Tool | Frank Munz "The approach is very generic and works for WebLogic, Glassfish or any other Java application," say Frank Munz. "UNIX commands in the example are run on CentOS, so they will work without changes for Oracle Enterprise Linux or RedHat. Creating the thread dump at the end of the video is done with the jcmd tool from JDK7." Frank has captured the process in the posted video.

  • How do I reinstate my admin user privileges to global read/write

    - by Matt
    I am running Ubuntu 12.04 LTS. I only have the one user which I created when I installed Ubuntu. Everything has been fine - love it - until I updated a software package recently from the command line using sudo (not gksudo). I was having a little bother which did not make sense to me and in a fluff changed my user read/write privileges through the GUI (not even clear how I got there!). After restart I was stuck in a login loop - using the right login password but kept getting looped back to the login and could only login as Guest. I could still login with my user/password via ctrl + alt + f1 Eventually I was able to login again at start up. Not sure exactly what it was I changed that worked but it was one of/or a combination of installing latest security updates, changing login manager from LightDM to DGM and back again, removing the ICE/Xauthority and chown user. Current dilemma is my primary admin user privileges were read only. In the command line ls -ls /home/user returned this value: drwx------ 48 username username 20480 I have since changed this using sudo chmod 0755 /home/username (from my limited understanding 755 should return my user privileges to their original read/write glory). ls -ld /home/user currently shows my user privileges as: drwxr-xr-x 48 username username 20480 I still seem to have only read access permissions. I've been through lots of threads (and the help file) that talk about creating new users/groups permissions etc. but specific info on returning my existing global/admin/primary users privileges to what they were when I first created that user - baffling me. I feel this is something really simple I'm just not getting it. Please help! sudo mount /dev/sda1 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /proc type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusect1 (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=07pe tmpfs55) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw, ,nosuid,nodev,size=5242880 none on /run/shm type tmpfs (rw,nosuid,nodev) gvfs-fuse-daemon on /home/meng/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=meng) none on /tmp/guest-1R2Fi5 type tmpsf (rw,mode=700)

  • How to send packets via a pptp vpn tunnel?

    - by Phill
    I'm trying to send certain port traffic through my ppp0 interface it's a pptp vpn tunnel, First, I'm using a wireless usb interface, I connect up to my access point, then I initiate my vpn, there is a connection but I do not channel all connexions through that, nor do I want to, so, say I want to channel all port 80 packets through my vpn (interface dev ppp0). I first run: iptables -t mangle -A OUTPUT -p tcp --dport 80 -j MARK --set-mark 0xa to mark the correct packets then I add a table named vpn_table, I then add ip route add default dev ppp0 table vpn_table when I do that traffic begins to dribble through the ppp0, but no pages load. I supose I must have caused some sort of coflict, or the route I'm adding in vpn_table isn't quite right. I'm not sure, I think I'm marking the packets correctly but I can't be sure of that either. UPDATE: I think i've got part of the issue solved: running tcpdump -i ppp0 showed me that indeed there was outgoing requests via ppp0, now, there is never a response, and pages do not load with using that interface..i'm still missing something.

  • Launching Ops Center 12c

    - by user12601629
    Oracle Enterprise Manager Ops Center 12c is most ambitious version of the Ops Center tooling that we've ever released. I think that make it appropriate that we launched it in grand style! When it became clear we were going to be complete with the 12c final release about this time of year, the marketing team proposed that we roll the launch of 12c into Oracle OpenWorld Tokyo.  I thought that sounded like a fine idea!  You see, I have always loved Japan.  I even studied a bit of Japanese language back in school. OpenWorld Tokyo was an outstanding even this year.  It was held in Roppongi, one of the most stylish districts in Tokyo. And, to make things even better, the Sakura (cherry blossoms) were blooming.  If you've never been in Japan for cherry blossom season, it's a must see!  Here are a couple of pics for you. Here is a picture from Roppongi, near the conference.  Here's a picture near the Imperial Palace.  A couple of friends from the local sales team took me here before my flight out. So, now back to the product launch! We choose to launch the product in John Fowler's "Engineered Systems" keynote address.  It made perfect sense because of the close ties of Ops Center to the Systems portfolio of products.  It was a packed house for the keynote.  Here's a picture I took just before we started -- there were also hundreds more people in "overflow" rooms in other parts of the venue. Here's a picture of me on stage during the launch. While there are countless new features in Ops Center 12c that customers will love, I had to limit myself to discussing just three. Mission Critical Clouds Solaris 11 Engineered Systems So, what does Mission Critical Cloud mean?  It means we've expanded EM's cloud capabilities in a couple of key areas. First, we've expanded the "self service provisioning" capabilities we have to include SPARC -- not just x86.  Now you can build clouds of Solaris Zones with ease!  Second, we've much more deeply integrated high-end storage and network management into the cloud layers.  These may our IaaS story is now much more powerful! For Solaris 11, we didn't simply port our monitoring agent to S11.  That would have been easy, but also boring! We support S11 deeply.  Full access to the power of the IPS packaging system, the new virtualized networking stack, new Zones features, the Auto Install framework.  If you're ready to try Solaris 11 then Ops Center is ready for you. Last is on the area of Engineered Systems.  These combinations of hardware and software are fast and powerful. However, we're also on a mission to make them ever easier to manage.  We've made major strides with Ops Center 12c. Manage these systems as racks, not individual components.  The new capabilities for the new engineered systems like Exalogic and SPARC SuperCluster and striking. You can read more here: Oracle Unveils Oracle Enterprise Manager Ops Center 12c So, I'll wrap this up with one final bit of fun. One of my friends from the Oracle marketing department found a super cool place to get dinner.  It's a restaurant called Gonpachi. It turns out this is the place that inspired the scene in the Quentin Taratino movie Kill Bill where Uma Thurman fights 88 Ninjas.  Here is a picture I snapped while we were there. It was surely a good time. Check it out next time you're in Tokyo.

  • Opening cursor files in a graphics editor?

    - by sdaau
    I'm looking at /usr/share/icons/DMZ-White/cursors, and there is: $ tree -s /usr/share/icons/DMZ-White/ /usr/share/icons/DMZ-White/ +-- [ 4096] cursors ¦   +-- [ 14] 00008160000006810000408080010102 -> v_double_arrow ... ¦   +-- [ 5] 9d800788f1b08800ae810202380a0822 -> hand2 ¦   +-- [ 8] arrow -> left_ptr ¦   +-- [ 15776] bd_double_arrow ¦   +-- [ 15776] bottom_left_corner ¦   +-- [ 15776] bottom_right_corner ¦   +-- [ 15776] bottom_side ... ... a bunch of files without extension, that GIMP cannot open. Is there an editor where these files can be opened - or at least a converter to something like .png? I can note that ImageMagick display also failed to open these files... Found also Gursor Maker - Cursor Editor for X11/GTK+; got the CVS code from SourceForge - it still uses Numeric (the old name of numpy), so to run it, you'll have to do: #from Numeric import * from numpy import * ... in xcurio.py, curxp.py, gimp.py, colorfunc.py - and comment the #from xml.dom.ext.reader import Sax2 in lsproj.py. With that, I got it running 11.04: ... but cannot get any files to open? So I thought I should grep for paths, nothing much came up - and when I looked into cursordefs.py, I simply had to paste this: CURSOR_ICON = gtk.gdk.pixbuf_new_from_xpm_data([ "10 16 3 1", " c None", ". c #000000", "+ c #FFFFFF", ".. ", ".+. ", ".++. ", ".+++. ", ".++++. ", ".+++++. ", ".++++++. ", ".+++++++. ", ".++++++++.", ".+++++....", ".++.++. ", ".+. .++. ", ".. .++. ", " .++. ", " .++. ", " .. "]) Heh :) In any case, doesn't look like it will be much usable on newer Ubuntus, unfortunately... Just tested XMC plugin as well - on 11.04, has to be built from source (from the link in the accepted answer); the requirements on my system resolved to: sudo apt-get install libgimp2.0-dev libglib2.0-0-dbg libglib2.0-0-refdbg libglib2.0-cil-dev libgtk2.0-0-dbg libgtk2.0-cil-dev ... after that, the configure/make procedure in the INSTALL file works. Note that this plugin is a bit "sneaky": ... that is, you should use "All files" (as there are no extensions); cursor previews at first will not be rendered. Then open one cursor file; after it has been opened, then there is a preview in the File/Open dialog; but other than that, it works fine...

  • Ubuntu installer doesn't see internal hard drive on DELL Vostro 3360

    - by valk
    I just received a new DELL Vostro 3360, it has Windows 7 preinstalled. When it comes to the partition window I can't see the hard drive there. I see only /dev/sda or /dev/sdb (either one and in both cases it's a usb drive from which I'm installing). I tried every imaginable BIOS configuration. Tried to change the SATA mode to ATA, DHCI and more. EDIT: I tried to install with standard Ubuntu 12.04 32 bit, and 11.10 64 bit official versions. No luck. I'll appreciate any suggestion.

  • Finding work as a college student

    - by lightburst
    I'm a 3rd year CS student. I'm currently really, really, bored and tired of cheap school programming(I go to a fairly respectable(albeit not top) university in my country, but, really, it's not MIT) so I've been thinking about getting a part-time dev job for a long while now. I'm not some hotshot programmer or anything, but "Add/Delete XYZ class objects to list" or "Do this web feature/pattern in PHP" does get old after a few semesters. I also only learned(heard?) of programming when I entered college, so the duration of me being in contact with any code is short. I can't really apply as an intern as I have not accumulated the necessary credits yet to do that so I was thinking of selling myself as a part-time dev. I still need to go to school, and don't want to subject myself to living two lives. Plus, I think I'd have better chances considering my lack of things to write on the resume. The only language I know at heart is C (I've written several pointer-oriented stuff on my freshman year, which is apparently pretty leet(for some reason), or so Joel says. That sort of boosted my morale a bit) but I've worked with several other languages only for the sake of course work such as C#/Java/PHP/ASM. My only user-worthy project was a recursive quicksort simulator I wrote for class using GTK+ that used a textbox to output the progress. I also have not taken the compiler theory class yet, or my thesis. All that being said, I wonder if any legitimate software company(big or small) would hire somebody like me considering all that. If there are companies that do accept anybody like me, would I be doing programming or maybe just be a tester or something? Would anybody hire me as a dev at all? I know I don't have much(not even a degree) but what I lack in experience, I compensate with interest? I am less interested in websites and 'management' software(no offense or anything. also, most of the places here ONLY have those), and more into 'process driven'(I'm not sure how to call it) and system software. I have my eyes on a startup that sells basically an extension of Google Drive, but I feel like I'm too 'risky' for them. Oh, I'm also 19 if that means anything. We're not K-12 so kids go to college earlier than in the US.

  • How to boot load the kernel using EFI stub (efistub) loader?

    - by Pro Backup
    I have Ubuntu 14.04 running in UEFI mode as only operating system, no dual-boot here. The kernel version is 3.13.0-24-generic. There is an EFI partition. In this case the EFI partition is not at the default /dev/sda1 but at /dev/sda3 because I did actually convert BIOS mode to EFI mode. I have used the grub-efi-amd64 package, though that actually loads GRUB boot menu from UEFI firmware boot menu (UEFI boot loads \EFI\ubuntu\grubx64.efi). I want to skip that double boot menu loading step, and boot faster, directly from UEFI into the kernel. The Ubuntu kernels since 12.10 have "Kernel EFI stub loader" feature. I know I do need to copy the Ubuntu kernel to the EFI partition (possibly rename) and create an entry in UEFI boot menu (for instance using efibootmgr). Which exact terminal commands are necessary to do this?

  • Add "not" to if statement in shell script

    - by John Crawford
    I have the following script that should exist if the user does not exist. #check if user currently exists on system if id $User > /dev/null 2>&1 then #user exists no need to exit program echo "blah blah, what a waste of space" else echo "This user does NOT exists. Please create that user before using this script.\n" exit fi My problem is that I would ideally like to place a "not" if that first if statement so that I can trim down my if, else statement. Ideally I would like something like this: if !(id $User > /dev/null 2>&1) then echo "This user does NOT exists. Please create that user before using this script.\n" exit fi

  • How to install MBR with Maverick or Karmic

    - by Kilos
    I have been using Ubuntu since 9.10. Now Maverick crashed and my MBR is wrecked. I have run dd if=/dev/zero of=/dev/sdb bs=512 count=1 on advice from another Ubuntu user but now I can only install any Windows release and no Ubuntu. How do I completely erase the MBR and then use an Ubuntu live CD or another HDD with Ubuntu on to install a Linux-only MBR please. I am rather new at the technical side of Linux and have bandwidth shortage problems so I can't download large amounts of data. Thanks in advance!

  • How to change harddrive spindown time?

    - by norpol
    if I run my notebook on battery mode, ubuntu spindown my hardrive every few seconds. How can I fix that? I have tried it with sudo hdparm -S 127 /dev/sda* but I am not able to disable the spindown and can´t find the reason for this "bug". Running Ubuntu 12.04 - Bug is since 12.04 Recent updates are installed, the problem is still recent. I can change the settings via. sudo hdparm -B 127 but if I change hdparm.conf, Ubuntu does not recognize it. /dev/sda { apm_battery=127 }

  • bash script move file to folders based in name

    - by user289111
    I hope you can help me... I made a perl and bash script to make a backup of my firewalls and tranfers via tftp #!/bin/sh perl /deploy/scripts/backups/10.160.23.1.pl > /dev/null 2>&1 perl /deploy/scripts/backups/10.160.23.2.pl > /dev/null 2>&1 so this tranfers the file to my tftp directory /tftpboot/ ls -l /tftpboot/ total 532 -rw-rw-rw- 1 tftp tftp 209977 jun 6 14:01 10.160.23.1_20140606.cfg -rw-rw-rw- 1 tftp tftp 329548 jun 6 14:02 10.160.23.2_20140606.cfg my questions is how to improve my script to moving this files dynamically to another folder based on the name (in this case on the ip address) for example: 10.160.23.1_20140606.cfg move to /deploy/backups/10.160.23.1/ is that the answer to this surely was on Google, but wanted to know if there was a particular solution to this request and also learn how to do :) Thanks!

  • Need Help Unable to Mount Location

    - by Don't ASk Ubun
    I am not able to start Windows and am using a DVD copy of Ubuntu to start up. I see my 750 GB Hard Disk, but if I click it i get this error: Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. After googling for a while I think I need to do sudo apt-get install ntfsprogs but when I try that: E: Package 'ntfsprogs' has no installation candidate My problem is a lot like this thread

  • How to enable TRIM on LVM on Ubuntu 12.10?

    - by Siddarth Kaki
    When I reinstalled Ubuntu 12.10 64-bit on my SSD, I chose the option to use LVM in Ubiquity. I am trying to find out how to enable TRIM for my SSD. I came across this article: http://worldsmostsecret.blogspot.com/2012/04/how-to-activate-trim-on-luks-encrypted.html The article states in addition to adding discard and noatime to /etc/fstab , discard must be added to the drive (sdX_crypt) in /etc/crypttab. My problem is the only listings in my /etc/crypttab are several cryptswap; it does not list any sdX_crypt. I currently have a /dev/sda1 (ext2), which is the boot point, and /dev/mapper/ubuntu-root, which is my ext4 partition. Any ideas as to how to enable TRIM?

  • Bridging 10GbE with 12.04 - bridging works but the bridging computer has no internet access

    - by Donal
    I have been trying to get 12.04 bridging working with two 10GbE cards. I have 2 10GbE cards in a linux box being used only for this bridge, 1 with 2 10GbaseT ports and another with a single CX4 port. I have 2 client computers connected with 10GbaseT cards and the CX4 card connects to a procurve switch. I can get the bridging happening mostly the way that I want, The clients receive dhcp information from the dhcp server (not the bridging machine) and can connect to and properly see the rest of the network. Speeds are ok, not amazing but working on that is another matter. My problem is that the bridging machine has no internet access ... meaning I can't update anything or apt-get anything It can ping all other machines on the local network. I've tried the helpful hints from: https://help.ubuntu.com/community/NetworkConnectionBridge "Enabling Internet Use on the Bridging Computer" and get the following RTNETLINK answers: File exists but dhclient br0 does nothing for me :( I think if it is anything it a multiple route problem as both br0 and eth4 have ipaddresses ... even though I have only set it up so that br0 has one ...
