• Mac OS X roaming profile from Samba with OpenLDAP backend on Ubuntu 11.10

  - by Sam Hammamy

  I have been battling for a week now to get my Mac (Mountain Lion) to authenticate on my home network's OpenLDAP and Samba. From several sources, like the Ubuntu community docs, and other blogs, and after a hell of a lot of trial and error and piecing things together, I have created a samba.ldif that will pass the smbldap-populate when combined with apple.ldif and I have a fully functional OpenLDAP server and a Samba PDC that uses LDAP to authenticate the OS X Machine. The problem is that when I login, the home directory is not created or pulled from the server. I get the following in system.log Sep 21 06:09:15 Sams-MacBook-Pro.local SecurityAgent[265]: User info context values set for sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got user: sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got ruser: (null) Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got service: authorization Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in od_principal_for_user(): no authauth availale for user.

Any help is appreciated, because I'm banging my head against the wall at this point. By the way, I intend to create a blog on my vps just for this, and create an install script in python that people can download so no one has to go through what I've had to go through this week :) After some sleep I am going to try to login from a windows machine and report back here. Thanks Sam

• SQL Developer Data Modeler: On Notes, Comments, and Comments in RDBMS

  - by thatjeffsmith

  Ah the beautiful data model. They say a picture is worth a 1,000 words. And then we have our diagrams, how many words are they worth? Our friends from the Human Relations sample schema So our models describe how the data ‘works’ – whether that be at a logical-business level, or a technical-physical level. Developers like to say that their code is self-documenting. These would be very lazy or very bad (or both) developers. Models are the same way, you should document your models with comments and notes! I have 3 basic options: Comments Comments in RDBMS Notes So what’s the difference? Comments You’re describing the entity/table or attribute/column. This information will NOT be published in the database. It will only be available to the model, and hence, folks with access to the model. Table Comments (in the design only!) Comments in RDBMS You’re doing the same thing as above, but your words will be stored IN the data dictionary of the database. Oracle allows you to store comments on the table and column definitions. So your awesome documentation is going to be viewable to anyone with access to the database. RDBMS is an acronym for Relational Database Management System – of which Oracle is one of the first commercial examples If the DDL is produced and ran against a database, these comments WILL be stored in the data dictionary. Notes A place for you to add notes, maybe from a design meeting. Or maybe you’re using this as a to-do or requirements list. Basically it’s for anything that doesn’t literally describe the object at hand – that’s what the comments are for. I totally made these up. Now these are free text fields and you can put whatever you want here. Just make sure you put stuff here that’s worth reading. And it will live on…forever.

• Network Solutions Gold VIP Program

  - by GGBlogger

  Today I received an email advising me “Congratulations! You have been selected for the Network Solutions Gold VIP Program” Now I get a bunch of messages from Network Solutions because a long time ago I chose them as my registrar. I usually just save these to my Outlook Network Solutions folder and move on. This time my wife was in the room and I chuckled and said something about “Network Solutions has made me a Gold VIP member.” She said “So what does that mean?” Prompted by that I scrolled down the page to look at my “perks". Let’s see – Special pricing, 1 year free Web Forwarding, 1 hour of free support… etc etc until I hit “Enrollment in SafeRenew* SafeRenew* simplifies your renewal process. It protects your domain name registrations and corresponding services in the event you forget or are unable to renew on time. I’m thinking “Now ain’t that neat” I don’t use auto renew anyway and never have. Then I continued reading: Beginning June 24th, 2012 your domains* (that’s 10 days away) will automatically renew. To ensure continuation of service, please be certain you have a valid credit card on file. If you do not wish for your services to be automatically renewed, please click here to log into account manager and opt out of the SafeRenew™ service. Whoa Network Solutions is going to start spending my money without so much as a by your leave sir!!! I don’t bloody think so and how truly magnanimous of them I can “click here” to opt out of what I didn’t opt in for. Talk about furious! I still am. Now the kicker is: if my wife hadn’t been curious and if I’d had a working credit card on file I wouldn’t have know this until one of my unwanted domain names auto renewed. Of course I was told “Oh – we’d have refunded your money” to which I say bull. In my view Networks Solutions is guilty of a crime of some sort. They DO NOT have a right to spend my money without asking!!!!! So watch out folks.

• Autoscaling in a modern world&hellip;. Part 3

  - by Steve Loethen

  The Wasabi Hands on Labs give you a good look at the basic mechanics, but I don’t find the setup too practical.  Using a local console application to host the Autoscaler and rules files is probably the (IMHO) least likely architecture.  Far more common would be hosting in a service on premise (if you want to have the Autoscaler local) or most likely, host it in a Azure role of it’s own.  I chose to go the Azure route. First step was to get the rules.xml and the services.xml files into the cloud.  I tend to be a “one step at a time” sort of guy, so running the console application with the rules sitting in a Azure hosted set of blobs seemed to be the logical first step.  Here are the steps: 1) Create a container in the storage account you wish to use.  Name does not matter, you will get a chance to set the container name (as well as the file names) in the app.config 2) Copy the two files from where you created them to your  container.  I used the same files I had locally.  I made the container public to eliminate security issues, but in the final application, a bit of security needs to be applied (one problem at a time).  The content type was set to text/xml.  I found one reference claiming the importance of this step, and it makes sense. 3) Adjust the app.config to set the location of the files.  This will let you set all the storage account and key information needed to reach into the cloud form your console application.  The sections of your app.config will look like this: <rulesStores> <add name="Blob Rules Store" type="Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.Rules.Configuration.BlobXmlFileRulesStore, Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling, Version=5.0.1118.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" blobContainerName="[ContainerName]" blobName="rules.xml" storageAccount="DefaultEndpointsProtocol=https;AccountName=[StorageAccount];AccountKey=[AccountKey]" monitoringRate="00:00:30" certificateThumbprint="" certificateStoreLocation="LocalMachine" checkCertificateValidity="false" /> </rulesStores> <serviceInformationStores> <add name="Blob Service Information Store" type="Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceModel.Configuration.BlobXmlFileServiceInformationStore, Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling, Version=5.0.1118.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" blobContainerName="[ContainerName]" blobName="services.xml" storageAccount="DefaultEndpointsProtocol=https;AccountName=[StorageAccount];AccountKey=[AccountKey]" monitoringRate="00:00:30" certificateThumbprint="" certificateStoreLocation="LocalMachine" checkCertificateValidity="false" /> </serviceInformationStores> Once I had the files up in the sky, I renamed the local copies to just to make my self feel better about the application using the correct set of rules and services.  Deploy the web role to the cloud.  Once it is up and running, start the console application.  You should find the application scales up and down in response to the buttons on the web site.  Tune in next time for moving the hosting of the Autoscaler to a worker role, discussions on getting the logging information into diagnostics into storage, and a set of discussions about certs and how they play a role.

• Plan Operator Tuesday round-up

  - by Rob Farley

  Eighteen posts for T-SQL Tuesday #43 this month, discussing Plan Operators. I put them together and made the following clickable plan. It’s 1000px wide, so I hope you have a monitor wide enough. Let me explain this plan for you (people’s names are the links to the articles on their blogs – the same links as in the plan above). It was clearly a SELECT statement. Wayne Sheffield (@dbawayne) wrote about that, so we start with a SELECT physical operator, leveraging the logical operator Wayne Sheffield. The SELECT operator calls the Paul White operator, discussed by Jason Brimhall (@sqlrnnr) in his post. The Paul White operator is quite remarkable, and can consume three streams of data. Let’s look at those streams. The first pulls data from a Table Scan – Boris Hristov (@borishristov)’s post – using parallel threads (Bradley Ball – @sqlballs) that pull the data eagerly through a Table Spool (Oliver Asmus – @oliverasmus). A scalar operation is also performed on it, thanks to Jeffrey Verheul (@devjef)’s Compute Scalar operator. The second stream of data applies Evil (I figured that must mean a procedural TVF, but could’ve been anything), courtesy of Jason Strate (@stratesql). It performs this Evil on the merging of parallel streams (Steve Jones – @way0utwest), which suck data out of a Switch (Paul White – @sql_kiwi). This Switch operator is consuming data from up to four lookups, thanks to Kalen Delaney (@sqlqueen), Rick Krueger (@dataogre), Mickey Stuewe (@sqlmickey) and Kathi Kellenberger (@auntkathi). Unfortunately Kathi’s name is a bit long and has been truncated, just like in real plans. The last stream performs a join of two others via a Nested Loop (Matan Yungman – @matanyungman). One pulls data from a Spool (my post – @rob_farley) populated from a Table Scan (Jon Morisi). The other applies a catchall operator (the catchall is because Tamera Clark (@tameraclark) didn’t specify any particular operator, and a catchall is what gets shown when SSMS doesn’t know what to show. Surprisingly, it’s showing the yellow one, which is about cursors. Hopefully that’s not what Tamera planned, but anyway...) to the output from an Index Seek operator (Sebastian Meine – @sqlity). Lastly, I think everyone put in 110% effort, so that’s what all the operators cost. That didn’t leave anything for me, unfortunately, but that’s okay. Also, because he decided to use the Paul White operator, Jason Brimhall gets 0%, and his 110% was given to Paul’s Switch operator post. I hope you’ve enjoyed this T-SQL Tuesday, and have learned something extra about Plan Operators. Keep your eye out for next month’s one by watching the Twitter Hashtag #tsql2sday, and why not contribute a post to the party? Big thanks to Adam Machanic as usual for starting all this. @rob_farley

• Dual booting 12.10 and Win 7 - boots directly to Win 7

  - by user110174

  and thank you kindly for you help! I'll preface this with saying that I realize this is a common problem, with lots of trouble-shooting guides available online; however, after multiple attempts with different guides, I've made zero progress and am hoping to someone could help me with my specific scenario. First, my story: -Initially, I installed Ubuntu 12.10 with the "Something Else" option with no problems. Used 4 GB Swap Logical Partition, 26 GB Primary Root Partition. Wanting to trying out Mint 13, I booted into Windows from GRUB2, used the latest version of EasyBCD (v2.2) to restore the Windows 7 bootloader to the MBR, deleted the Ubuntu partitions, reformatted them in NTFS. I then created a 30 GB partition of free space for Mint. I installed Mint using the same partitioning described above for Ubuntu 12.10, using /dev/sda for the boot installation files, and everything seemed to go well, until I re-booted my computer and it went straight to Windows - I could find no way to get into Mint. So I went into windows, restored windows bootloader to the MBR w/ EasyBCD, deleted partitions, etc., as I figured I'd done enough messing around and would go with Ubuntu 12.10. Now the problem: I restarted my computer booting from the same Ubuntu USB key I originally used. Briefly, "error: "prefix" is not set" flashed on screen, and instead of being greeted with the GUI menu of "try vs. install Ubuntu", there was a menu with minimal graphics (like a BIOS menu) where I could select install, run from USB, etc. After selecting "Install Ubuntu", the familiar install wizard with a GUI came up, I partitioned my drive as described, /dev/sda for the boot installation files, install went well, rebooted and...straight to Windows. This is where I'm at. Fixes I've tried: -This guide: How can I repair grub? (How to get Ubuntu back after installing Windows?) to ensure Grub is on the MBR. I followed all steps, but still when I reboot, I go directly into Windows. -Installing 12.04 instead of 12.10 - same issue -Re-installed Ubuntu, writing the boot files to their own partition, then using EasyBCD to to add a boot option for Ubuntu using the Windows bootloader, ensuring I instruct EasyBCD to look at the partition I created with the Ubuntu installer (instructions here http://neosmart.net/wiki/display/EBCD/Ubuntu). When I reboot, I select the Ubuntu option, and it puts me in GRUB4DOS, with a cursor waiting for input. I have no idea what to put here, so I would just type "reboot" to exit out. And this is where I am now. Any clue as to why I can't boot into Ubuntu? My computer specs are: ASUS UX31A Core i7, Win 7 64 Pro, 256 GB SSD, Intel HM76 Chipset and Integrated Intel HD 4000 Graphics, 4 GB memory I've tried to be as clear as possible, but I'd be happy to provide any info that would help anyone along. Thanks for your patience in reading this! Sincerely, -MN

• Oracle Releases New Mainframe Re-Hosting in Oracle Tuxedo 11g

  - by Jason Williamson

  I'm excited to say that we've released our next generation of Re-hosting in 11g. In fact I'm doing some hands-on labs now for our Systems Integrators in Italy in a couple of weeks and targeting Latin America next month. If you are an SI, or Rehosting firm and are looking to become an Oracle Partner or get a better understanding of Tuxedo and how to use the workbench for rehosting...drop me a line. Oracle Tuxedo Application Runtime for CICS and Batch 11g provides a CICS API emulation and Batch environment that exploits the full range of Oracle Tuxedo's capabilities. Re-hosted applications run in a multi-node, grid environment with centralized production control. Also, enterprise integration of CICS application services benefits from an open and SOA-enabled framework. Key features include: CICS Application Runtime: Can run IBM CICS applications unchanged in an application grid, which enables the distribution of large workloads across multiple processors and nodes. This simplifies CICS administration and can scale to over 100,000 users and over 50,000 transactions per second. 3270 Terminal Server: Protects business users from change through support for tn3270 terminal emulation. Distributed CICS Resource Management: Simplifies deployment and administration by allowing customers to run CICS regions in a distributed configuration. Batch Application Runtime: Provides robust IBM JES-like job management that enables local or remote job submissions. In addition, distributed batch initiators can enable parallelization of jobs and support fail-over, shortening the batch window and helping to meet stringent SLAs. Batch Execution Environment: Helps to run IBM batch unchanged and also supports JCL functionality and all common batch utilities. Oracle Tuxedo Application Rehosting Workbench 11g provides a set of automated migration tools integrated around a central repository. The tools provide high precision which results in very low error rates and the ability to handle large applications. This enables less expensive, low-risk migration projects. Key capabilities include: Workbench Repository and Cataloguer: Ensures integrity of the migrated application assets through full dependency checking. The Cataloguer generates and maintains all relevant meta-data on source and target components. File Migrator: Supports reliable migration of datasets and flat files to an ISAM or Oracle Database 11g. This is done through the automated migration utilities for data unloading, reloading and validation. It also generates logical access functions to shield developers from data repository changes. DB2 Migrator: Similarly, this tool automates the migration of DB2 schema and data to Oracle Database 11g. COBOL Migrator: Supports migration of IBM mainframe COBOL assets (OLTP and Batch) to open systems. Adapts programs for compiler dialects and data access variations. JCL Migrator: Supports migration of IBM JCL jobs to a Tuxedo ART environment, maintaining the flow and characteristics of batch jobs.

• How To: Automatically Remove www from a Domain in IIS7

  I recently moved the DevMavens.com site from one server to another and needed to ensure that the www.devmavens.com domain correctly redirected to simply devmavens.com.  This is important for SEO reasons (you dont want multiple domains to refer to the same content) and its generally better to use the shorter URL (www is so 20th century) rather than wasting 4 characters for zero gain. My friend and IIS guru Scott Forsyth pointed me to his blog post on how to set up IIS URL Rewriting.  To get started, you simply install IIS Rewrite from this link using the super awesome Web Platform Installer.  You should get something like this when youre done with the install: If you already have IIS Manager open, you may need to close it and re-open it before you see the URL Rewrite module.  Once you do, you should see it listed for any given Site under the IIS section: Double click on the URL Rewrite icon, and then choose the Add Rule(s) action.  You can simply create a blank rule, and name it Redirect from www to domain.com.  Essentially were following the instructions from Scott Forsyths post, but in reverse since hes showing how to add 4 useless characters to the URL and Im interested in removing them. After adding the name, well set the Match Url sections Using dropdown to Wildcards and specify a pattern of simply * to match anything. In the Conditions section we need to add a new condition with an Input of {HTTP_HOST} such that it should match the pattern www.devmavens.com (replace this with your domain). Ignore the Server Variables section. Set the action to Redirect and the Redirect URL to http://devmavens.com/{R:0} (replace with your domain).  The {R:0} will be replaced with whatever the user had entered.  So if they were going to http://www.devmavens.com/default.aspx theyll now be going to http://devmavens.com/default.aspx. The complete Inbound Rule should look like this: Thats it!  Test it out and make sure you havent accidentally used my exact URLs and started sending all of your users to devmavens.com! :)  Be sure to read Scotts post for more information on how to use regular expressions for your rules, and how to set them up via web.config rather than IIS manager. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Issues with timed out downloads via TomCat?

  We get, in our opinion, a lot of failed download attempts and want to understand why. We offer downloads via an email link (typical): http://www.semanticdesigns.com/deliverEval/<productname> This is processed by Tomcat on Linux via a jsp file, with the following code: response.addHeader( "Content-Disposition", "attachment; filename=" + fileTail ); response.addHeader( "Content-Type", "application/x-msdos-program" ); byte[] buf = new byte[8192]; int read; try { java.io.FileInputStream input = new java.io.FileInputStream( filename ); java.io.OutputStream o = response.getOutputStream(); while( ( read = input.read( buf, 0, 8192 ) ) != -1 ){ o.write( buf, 0, read ); } o.flush(); } catch( Exception e ){ util.fatalError( request.getRequestURI(), "Error sending file '" + filename + "' to client", e ); throw e; } We get a lot of reported errors (about 50% error rate): URI --- /deliverEval/download.jsp Code Message: Error sending file '/home/sd/ShippingMasters/DMS/Domains/C/GCC3/Tools/TestCoverage/SD_C~GCC3_TestCoverage.1.6.12.exe' to client Stack Trace ----------- null at org.apache.coyote.tomcat5.OutputBuffer.realWriteBytes(byte[], int, int) (Unknown Source) at org.apache.tomcat.util.buf.ByteChunk.append(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.writeBytes(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.write(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.CoyoteOutputStream.write(byte[], int, int) (Unknown Source) at org.apache.jsp.deliverEval.download_jsp._jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at org.apache.jasper.runtime.HttpJspBase.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.jasper.servlet.JspServletWrapper.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.serviceJspFile(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.String, java.lang.Throwable, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.StandardWrapperValve.invoke(org.apache.catalina.Request, org.apache.catalina.Response, org.apache.catalina.ValveContext) (Unknown Source) We don't understand why this rate should be so high. Is there any way to get more information about the cause of the error? It is useful to know that these are pretty big documents, 3-50 megabytes. They reside on the Linux server so reading them is just a local disk read, and is unlikely to be a contributor to the problem. But sheer size might be an issue for the recipients browser? Is this kind of error rate typical for downloads? My personal experience downloading other's documents suggests no; our internal attempts show this to be very reliable, but we're operating on our internal network for such experiments so we're missing the complexity of the intervening internet.

• ath9k driver does not weak up

  - by shantanu

  I know this is common question but i found no suitable answer, so i am asking this again. I installed ubuntu 11.10. I found the bug for ath9k, so set first network boot from BIOS menu. That's worked. I have upgraded to 12.04 yesterday. Now ath9k is creating problem again. First network boot is still enable. ath9k works at start. But failed(connect again and again) after couple of minutes. dmesg show error that it can not weak up in 500us. So i tried #compat-wireless-3.5.1-1. But result is same.

• Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI

  - by Rohan Dhruva

  I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows. The only things I can think of are: The sda1 partition is somehow being used Overwrite /EFI/Boot/bootx64.efi and /EFI/Microsoft/Boot/bootmgfw.efi with grubx64.efi [but this seems really radical]. Can anyone please help me out? Thanks -- any help is greatly appreciated, as this issue is driving me crazy!

• Gparted can't create partition table

  - by William

  Here's what the problem is. About a day or so ago I used Gparted live cd to create 3 NTFS primary partitions on my external 500 gig Goflex and one extended with 2 logical partitiones. I had planned to install windows 8 on the first partition, then ubuntu and kubuntu on the other 2. After I finished partitioning my drive with gparted, I booted into windows vista to make my bootable windows 8 usb to install it with, I also decided to check to make sure all my partitions were working properly. Then I found they were, and they weren't. My 50 gig first partition I had planned to install windows on showed up normal and the 300 gigs of space left in the extended partition did as well, the rest showed up as raw. So I figured alright, something went awal while making the partitions, so I booted up gparted once again. Then to my surprise gparted showed the entire drive as unallocated, and when I refreshed the list, it showed as all the partitions I had made earlier, buy with a exclamation mark by them all. So I figured ok, might be a problem with the partition table as I'd seen a similar problem in past on a drive that was not partitioned at all, so I decided to create a new partition table and take the time out again to sit and wait. Then I got a message saying gparted could not create the partition table, followed by it showing the entire drive as formatted into ntfs. After that I figured ok I'll take a break, come back in a hour, maybe it's something I did. So a hour later I came back after having booted up windows, plugged the drive in to see if by some miracle windows could access the drive. In disk management when I plugged the drive in, it would freeze attempting to read the drive, as I'd seen in the past with raw disks, yet when I unplugged it I got a glimpse of disk management showing it as a perfectly fine ntfs file system on the drive followed by a "you must format disk K in order to use it". So I then was assured the disk was raw as that is what had happened in the past, followed by a new partition table through gparted to fix the problem and a 10 hour format in windows. So I once again booted up gparted, to get the message "error fsyncing/closing/dev/sdg:input/output error" followed by "error opening dev/sdg No such file in directory" after I refreshed and somehow saw the disk show up as perfectly fine ntfs and then tried to create a new partition table to try to wipe out all my problems and start over again. And not gparted only shows the drive there about 1/10 refreshes the rest I get the directory error. If anybody can assist me in any way shape or form I will be thankful.

• Running Apache and Tomcat together on different subdomains?

  - by Ritesh M Nayak

  Posted this on ServerFault but didn't get a response. Hoping I will have better luck on the Ubuntu site. I have been trying to get this working the whole of today. I have a server which resolves to the domain example.com . This is running Apache2 and Tomcat 6. The requirement is to direct requests to example.com to apache2 and app.example.com to Tomcat. I know I have to do a VirtualHost proxy pass for this to work. Here are the settings on my server. /etc/hosts file looks something like this 127.0.0.1 localhost localhost.localdomain example.com app.example.com I have two virtual host files for the different domains in /etc/apache2/sites-enabled /etc/apache2/sites-enabled/example.com looks like this <VirtualHost *:80> # Admin email, Server Name (domain name) and any aliases ServerAdmin webmaster@localhost ServerName example.com ServerAlias www.example.com DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

I have a CNAME entry for both example.com and app.example.com. When accessing app.example.com, I get an 403 forbidden, saying I have no access to / on the server. What am I doing wrong?

  It is difficult to write about Microsoft's ambivalence to .NET without mentioning clichés about dog food.  In case you've been away a long time, you'll remember that Microsoft surprised everyone with the speed and energy with which it introduced and evangelised the .NET Framework for managed code. There was good reason for this. Once it became obvious to all that it had sleepwalked into third place as a provider of development languages, behind Borland and Sun, it reacted quickly to attract the best talent in the industry to produce a windows version of the Java runtime, with Bounds-checking, Automatic Garbage collection, structures exception handling and common data types. To develop applications for this managed runtime, it produced several excellent languages, and more are being provided. The only thing Microsoft ever got wrong was to give it a stupid name. The logical step for Microsoft would be to base the entire operating system on the .NET framework, and to re-engineer its own applications. In 2002, Bill Gates, then Microsoft Chairman and Chief Software Architect said about their plans for .NET, "This is a long-term approach. These things don't happen overnight." Now, eight years later, we're still waiting for signs of the 'long-term approach'. Microsoft's vision of an entirely managed operating system has subsided since the Vista fiasco, but stays alive yet dormant as Midori, still being developed by Microsoft Research. This is an Internet-centric fork of the singularity operating system, a research project started in 2003 to build a highly-dependable operating system in which the kernel, device drivers, and applications are all written in managed code. Midori is predicated on the prevalence of connected systems, with provisions for distributed concurrency where application components exist 'in the cloud', and supports a programming model that can tolerate cancellation, intermittent connectivity and latency. It features an entirely new security model that sandboxes applications for increased security. So have Microsoft converted its existing applications to the .NET framework? It seems not. What Windows applications can run on Mono? Very few, it seems. We all thought that .NET spelt the end of DLL Hell and the need for COM interop, but it looks as if Bill Gates' idea of 'not overnight' might stretch to a decade or more. The Operating System has shown only minimal signs of migrating to .NET. Even where the use of .NET has come to dominate, when used for server applications with IIS, IIS itself is still entirely developed in unmanaged code. This is an irritation to Microsoft's greatest supporters who committed themselves fully to the NET framework, only to find parts of the Ambivalent Microsoft Empire quietly backsliding into unmanaged code and the awful C++. It is a strategic mistake that the invigorated Apple didn't make with the Mac OS X Architecture. Cheers, Laila

• ETPM Environment Health Monitoring Tools

  - by Paula Speranza-Hadley

  This post is to provide some useful information about the tools typically used by Oracle ETPM implementations for performance tuning and analysis.   This includes tools to monitor and gather performance information and statistics on the Database, Application Server, and Client (browser).  Enterprise Monitoring Tools Oracle Enterprise Manager - OEM Grid Control comes with a comprehensive set of performance and health metrics that allow monitoring of key components in your environment such as applications, application servers, databases, as well as the back-end components on which they rely, such as hosts, operating systems and storage. Tools for the Database Oracle Diagnostics Pack Automatic Workload Repository (AWR)  - this tool gets statistics from memory abut the Time Model or DB Time, Wait Events, Active Session History and High Load SWL queries Automatic Database Diagnostic Monitor (ADDM) - This self-diagnostic software is built into the database.  It examines and analyzes data captured in AWR to dertermine possible performance issues.  It locates the root cause of the issue, provides recommendations for correcting the issues and qualifies the expected benefit. Oracle Database Tuning Pack SQL Tuning Advisor - This enables you to submit one or more SQL statements as input and receive output in the form of specific advice or recommendations on how to tune statements.  The recommendation relates to collection of statistics on objects, creation on new indexes and restructuring of SQL statements. SQL Access Advisor - This enables you to optimize data access paths of SQL queries by recommending a proper set of materialized views, indexes and partitions for a given SQL workload. Tools for the Application Server Weblogic Console - is a web-based, user interface used to configure and control a set of WebLogic servers or clusters (i.e. a "domain").  In any logical group of WebLogic servers there must exist one admin server, which hosts the WebLogic Admin console application and manages the associated configuratoin files. WebLogic Administrators will use the Administration Console for a number of tasks, including: Starting and stopping WebLogic servers or entire clusters. Configuring server parameters, security, database connections and deployed applications. Viewing server status, health and metrics. Yourkit for Profiling - helps analyze synchronization issues, including: Which threads were calling wait(), and for how long Which threads were blocked on attempt to acquire a monitor held by another thread (synchronized methods/blocks), and for how long Tools for the Client Fiddler - allows you to inspect traffic logs, debug and set breakpoints. Firebug – allows you to inspect and edit HTML, monitor network activity and debug JavaScript

• Case Management Patterns with Oracle Unified Business Process Management Suite

  - by Ajay Khanna

  Contributed by Heidi Buelow, Oracle Product Management Case Management was a hot topic all week at Oracle OpenWorld so I was excited to share our current features and upcoming plans at the session Thursday morning on Case Management Patterns with Oracle Unified Business Process Management Suite.  My colleague, Ravi Rangaswamy, the Case Management Development Manager, and I, Heidi Buelow, the Case Management Product Manager, discussed case management use case patterns with an interested audience.  We also talked about the current BPM Suite offering for Case Managment and showed a demo of our upcoming release where Case Management becomes a first class component in a BPM composite application. Case Management use case patterns cover a wide range of horizontal applications such as Accounts Payable, Dispute Resolution, Call Center, Employee OnBoarding, and many vertical applications in domains and industries such as Public Sector services, Insurance claims, and Healthcare.  Really, it is any use case where the resolution of a request may require a knowledge worker making decisions using experienced judgement in the current situation.  This allows for expidited care and customer satisfaction, both being highly valued for consumer loyalty, regulatory compliance, and efficient resolution. Today, BPM Suite provides the tools for creating Case Management applications using BPMN 2.0, Business Rules, and rich BAM and Case Analytics.  The Process Composer provides the agility to change rules and processes by the business users.  The case manager and case workers have the flexibilty they need.  With integrated content management and the concept of a BPM Process Spaces instance (case) space, the current release enables case management use case applications. In the next release, Case Management becomes a first class component. By this, we mean, Case is a separate component in the composite.  We are adding case attributes such as milestones, case events, case stakeholders, and more, providing a rich toolset for the use cases that require a flexible Case Management approach.  Activites become available according to the conditions that you specify and information can be protected by permissions indicated.  In BPM Studio, you design a Case and associate all of the attributes and activities that are needed, yet, at runtime you have the flexibility to add and change these as needed. We enjoyed sharing Case Management and it was well received by the audience.  The presentation is available online and we have viewlets of the demo that will be available at release time.

• Source of (programmer) inefficiency

  - by Daniel

  I am interested to gain a better insight about the possible reasons of personal inefficiency as programmers (and only in programming) due to – simply - our own errors (because we are humans – well, almost all of us). I am not interested in how much we are productive or in how many adjustements the customer asks for when the work is done, but where and how each of us spend that part of its time in tasks that are unproductive and there is no one to blame except ourselves. Excluding ego - feeding and / or self – gratification, what I am trying to get (for all of us) is: what are the common issues eating our time; insight on reasons for that issues; identify simple way for us, personally (not delegating actions to other or our organizations), to correct our own problems. Please, do not think in academic terms but aim at the opportunity to compare our daily experiences and understand what are and how we try to fix our personal deficiencies. If you are interested to respond to this post, please: integrate the list if you see something important (or obvious) missing; highlight or name honestly your first issue tellng the way you try to address and solve your issue acting on yourself and yourself only in a sort of "continuous quality improving" My criteria for accepting the answer is: choose the best solution (feasibility and utility) to fix one (or more) of the problems of the list. Of course, selecting an error is not a vote on our skills: maybe we are hyper professional programmers and we lose ten minutes only every year or we are terribly inefficient, losing a couple of days a week: reasons for inefficiency could be really the same - but in a different scale. A possible list: Plain error in the names (variables, functions). Inability to see the obvious in your code. Misreading. Lack of concentration. Trying to use a technology you have not mastered. Errors with data types. Time required to understand your previous code or your documentation. Trying to do something more than requested because you enjoy it Using solutions more complicated than required because you enjoy it. Plain logical errors. Errors due to your fault in communications. Distraction My first personal issue: "Trying to use a technology you do not master." I have to use daily several technologies and I often need to spend significant time correcting code because my assumptions were plainly wrong. Reasons for this: production needs put high pressure and make difficult to find the time to learn. I try to address this reading technical books - as many as I can - even if this actually consumes a lot of time.

• How To Build An Enterprise Application - Introduction

  - by Tuan Nguyen

  An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure
