• ruby on rails gitorious setup on ubuntu

  - by dogmatic69

  Ive been trying to install gitorious for a while now which required ruby and rails etc. Ive finally got rails pages serving but cant finish the installation of gitorious because the gem version is too new. the error logs say please run 'rake ultrasphinx:configure' and that gives rake ultrasphinx:configure (in /var/www/apps/gitorious) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /var/www/apps/gitorious/Rakefile:10:in `require' (See full trace by running task with --trace) From searching google this is beacuse of the wrong gem verison. Cant find a way to down grade it. apparently sudo gem update --system 1.4.2 should do the trick but ubuntu 10.10 does not like this. ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories. If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian. So i added export REALLY_GEM_UPDATE_SYSTEM=1 to .bashrc and reloaded it with . ~/.bashrc and still the same. ive tried various forms of setting this environmental variable with no luck. Ive also been told on #gitorious irc channel to add the file config/initializers/rubygems.rb with the line require "thread" to it. This has done nothing. EDIT: Just found another way which was rvm install rubygems 1.4.2 and it gave: Removing old Rubygems files... Installing rubygems dedicated to ruby-1.8.7-p334... Retrieving rubygems-1.4.2 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 288k 100 288k 0 0 282k 0 0:00:01 0:00:01 --:--:-- 414k Extracting rubygems-1.4.2 ...

• Why is mount -a not mounting fuse drive properly when executed remotely (via Fabric)?

  - by Jim D

  This is a weird bug and I'm not sure where it's coming from. Here's a quick run down of what I'm doing. I'm trying to mount a FUSE drive to an Amazon EC2 instance running Ubuntu 10.10 using s3fs (FUSE over Amazon). s3fs is compiled from source according to the instructions etc. I've also added an entry to /etc/fstab so that the drive mounts on boot. Here's what /etc/fstab looks like: # /etc/fstab: static file system information. # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 LABEL=uec-rootfs / ext4 defaults 0 0 /dev/sda2 /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 /dev/sda3 none swap sw,comment=cloudconfig 0 0 s3fs#mybucket /mnt/s3/mybucket fuse default_acl=public-read,use_cache=/tmp,allow_other 0 0 So the good news is that this works fine. On reboot the connection mounts correctly. I can also do: $ sudo umount /mnt/s3/mybucket $ sudo mount -a $ mountpoint /mnt/s3/mybucket /mnt/s3/mybucket is a mountpoint Great, right? Well here's the problem. I'm using Fabric to automate the process of building and managing this instance. I noticed I was getting this error message when using Fabric to build s3fs and set up the mount process: mountpoint: /mnt/s3/mybucket: Transport endpoint is not connected I isolated it down the the problem and built a fabric task that reproduces the problem: def remount_s3fs(): sudo("mount -a") Which does: [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] Executing task 'remount_s3fs' [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] sudo: mount -a [And yes, I was sure to unmount it before running this task.] When I check the mount using mountpoint I get: $ mountpoint /mnt/s3/mybucket mountpoint: /mnt/s3/mybucket: Transport endpoint is not connected Done. But if I run sudo mount -a at the command line, it works. Hrm. Here is that fab task output again, this time in full debug mode: [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] Executing task 'remount_s3fs' [ec2-xx-xx-xx-xx.compute-1.amazonaws.com] sudo: sudo -S -p 'sudo password:' /bin/bash -l -c "mount -a" Again, I get that transport endpoint not connected error. I've also tried copying and pasting the exact command run into my ssh session (i.e. sudo -S -p 'sudo password:' /bin/bash -l -c "mount -a") and it works fine. So...that's my problem. Any ideas?

• Statistics for and Details About Open Source Swing Projects

  - by user592704

  I'm looking for process-relative information on open-source Swing projects: how the task was described how many developers were involved how much time the solution was taken etc. Are there any open source (online) chronicles in that direction? I strongly prefer projects that include the authors' names. I watched this project and it seems fine but still I couldn't find any information concerning some current project task(s), its developers group, some chronicles (tips, milestones, feedbacks etc) For example if I see this swing component I'd like to know the above information.

  In the attempt to understand why I keep getting the following error error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)' while using the command sudo find / -type s the terminal prompted something like this find: ‘/proc/31348/task/31348/fd/5’: No such file or directory find: ‘/proc/31348/task/31348/fdinfo/5’: No such file or directory find: ‘/proc/31348/fd/5’: No such file or directory find: ‘/proc/31348/fdinfo/5’: No such file or directory What does this mean?

• Download files from a SharePoint site using the RSSBus SSIS Components

  - by dataintegration

  In this article we will show how to use a stored procedure included in the RSSBus SSIS Components for SharePoint to download files from SharePoint. While the article uses the RSSBus SSIS Components for SharePoint, the same process will work for any of our SSIS Components. Step 1: Open Visual Studio and create a new Integration Services Project. Step 2: Add a new Data Flow Task to the Control Flow screen and open the Data Flow Task. Step 3: Add an RSSBus SharePoint Source to the Data Flow Task. Step 4: In the RSSBus SharePoint Source, add a new Connection Manager, and add your credentials for the SharePoint site. Step 5: Now from the Table or View dropdown, choose the name of the Document Library that you are going to back up and close the wizard. Step 6: Add a Script Component to the Data Flow Task and drag an output arrow from the 'RSSBus SharePoint Source' to it. Step 7: Open the Script Component, go to edit the Input Columns, and choose all the columns. Step 8: This will open a new Visual Studio instance, with a project in it. In this project add a reference to the RSSBus.SSIS2008.SharePoint assembly available in the RSSBus SSIS Components for SharePoint installation directory. Step 9: In the 'ScriptMain' class, add the System.Data.RSSBus.SharePoint namespace and go to the 'Input0_ProcessInputRow' method (this method's name may vary depending on the input name in the Script Component). Step 10: In the 'Input0_ProcessInputRow' method, you can add code to use the DownloadDocument stored procedure. Below we show the sample code: String connString = "Offline=False;Password=PASSWORD;User=USER;URL=SHAREPOINT-SITE"; String downloadDir = "C:\\Documents\\"; SharePointConnection conn = new SharePointConnection(connString); SharePointCommand comm = new SharePointCommand("DownloadDocument", conn); comm.CommandType = CommandType.StoredProcedure; comm.Parameters.Clear(); String file = downloadDir+Row.LinkFilenameNoMenu.ToString(); comm.Parameters.Add(new SharePointParameter("@File", file)); String list = Row.ServerUrl.ToString().Split('/')[1].ToString(); comm.Parameters.Add(new SharePointParameter("@Library", list)); String remoteFile = Row.LinkFilenameNoMenu.ToString(); comm.Parameters.Add(new SharePointParameter("@RemoteFile", remoteFile)); comm.ExecuteNonQuery(); After saving your changes to the Script Component, you can execute the project and find the downloaded files in the download directory. SSIS Sample Project To help you with getting started using the SharePoint Data Provider within SQL Server SSIS, download the fully functional sample package. You will also need the SharePoint SSIS Connector to make the connection. You can download a free trial here. Note: Before running the demo, you will need to change your connection details in both the 'Script Component' code and the 'Connection Manager'.

The nodes run a vanilla installation of Ubuntu Server 12.04 64-bit and DSE was installed and secured according to the provided installation documentation. I have been experiencing that problem on my development cluster for a while too (with DSE 4.0.0, 4.0.1 and 4.0.2), but I thought this was because of some configuration error on my part. The problem has appeared spontaneously at some point too. The Cassandra cluster has been working very smoothly with a good write throughput. It is very stable and has enough resources to work with. We did not notice any problems with the applications that depend on it.

• SQL Server Integration Services package to delete files from a Network or Local path based on date

  We have a requirement to delete a group of files that are older than the specified number of days from the company file share. Due to the complex folder hierarchy and delicate nature of the data stored in these files, this task has to be originated from SQL Server. However, due to company security policy, and based on SQL Server security best practices, we blocked access to OLE Automation stored procedures, CLR features, and xp_cmdshell. Is there any way to accomplish this task without using these features?

• Planning a Website and What to Expect

  A successful project begins with careful planning. No matter what the size of the task at hand (whether running errands or plotting for world domination), ample thought needs to be given to the task as a whole before the work begins. This is especially true for website development. Planning the strategy for the site and how the website fits into the larger vision of the project beyond the scope of the online presence is an absolutely essential phase for both the website developer and the client.

• Configure Cucumber with SentientUser

  - by Corith Malin

  I have an application using the SentientUser gem to provide the current user to my models. On top of that I'm using default scoping to ensure that a user can only ever access data that they own. So a typical model for me looks something like this: class Location < ActiveRecord::Base validates_presence_of :name, :time_zone, :address belongs_to :account belongs_to :address accepts_nested_attributes_for :address default_scope :conditions => { :account_id => User.current.account } end When I run rake cucumber I get an error on the default_scope line about account being nil. My guess is that when the cucumber rake task is run it doesn't have access to the correct application controller to inject the current_user method and thus SentientUser can't get the current user? The error I get is: rake cucumber (in /Users/corithmalin/Documents/Code/Ruby/flavorpulse) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I "/Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/lib:lib" "/Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/cucumber" --profile default Using the default profile... undefined method `account' for nil:NilClass (NoMethodError) /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/whiny_nil.rb:52:in `method_missing' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/app/models/location.rb:9 /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `polyglot_original_require' /Library/Ruby/Gems/1.8/gems/polyglot-0.3.0/lib/polyglot.rb:65:in `require' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:158:in `require' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:265:in `require_or_load' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:224:in `depend_on' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/vendor/rails/activesupport/lib/active_support/dependencies.rb:136:in `require_dependency' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:414:in `load_application_classes' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:413:in `each' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:413:in `load_application_classes' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:411:in `each' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:411:in `load_application_classes' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:197:in `process' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:113:in `send' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/../vendor/rails/railties/lib/initializer.rb:113:in `run' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/config/environment.rb:9 /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `polyglot_original_require' /Library/Ruby/Gems/1.8/gems/polyglot-0.3.0/lib/polyglot.rb:65:in `require' /Users/corithmalin/Documents/Code/Ruby/flavorpulse/features/support/env.rb:8 /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `polyglot_original_require' /Library/Ruby/Gems/1.8/gems/polyglot-0.3.0/lib/polyglot.rb:65:in `require' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/rb_support/rb_language.rb:124:in `load_code_file' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:85:in `load_code_file' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:77:in `load_code_files' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:76:in `each' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/step_mother.rb:76:in `load_code_files' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/cli/main.rb:48:in `execute!' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/../lib/cucumber/cli/main.rb:20:in `execute' /Library/Ruby/Gems/1.8/gems/cucumber-0.6.3/bin/cucumber:8 rake aborted!

• Cannot run "Automation Anywhere" exe files from console (session 0) on Windows Server 2003 64 bit

  - by Tyler

  I have a simple exe created from an Automation Anywhere task that displays a message box saying hello world. I created this simple exe just for debugging the following issue. When I log in to the console (session 0), and run the Automation Anywhere created executable, it starts to run the task, it shows up in the applications and processes list in the task manager and it shows the two "loading..." windows briefly on the screen, just like normal. But after that, nothing happens... the "hello world" message does not show up. The exe is done and is removed from the application and process list in the task manager. The user I am logged in as, has admin rights and the machine uses "autologin" to automatically log in using this profile when it starts up. If I right click on the exe and "run as" another admin user, the exe runs properly, showing the "hello world" message. Also, if I log into the server in a new session, with the original user (the one that has the problems in session 0), and then run the exe, it runs properly and shows the "hello world". It works fine in any session other than the console session. There is something about the console session that is causing the exe not to run properly... even though it does appear to start running the exe. I should also mention that everything was working fine until Monday at midnight, after which none of the executables could be run successfully. Nothing was changed on the server and no updates were installed. I have since installed windows updates, but that didn't change anything. Looking for some advice on how to get these executables working in the console session again. Thanks!

• Scripting an automated SQLServer 2008 DR move

  - by ItsAMystery

  Hi All We use the built in logshipping in SQLServer to logship to our DR site but once in a month do a DR test which requires us to move back and forth between our Live and BAckup servers. We run multiple (30) databases on the system so manually backing up the final logs and disabling the jobs is too much work and takes too long. I though no problem, I will script it but have run into trouble with it always complaninig that the final logship is too early to apply even though I dont export the final log until putting the database into norecovery mode. Firstly, does any one no a simple and reliable way of doing this? I have lokoed at some 3rd party software (redgate sqlbackup I think it was) but that didnt make it easy in this situation either. What I want to be able to do is basically run a script (a series of stored procedures) to get me to DR and run another to get me back with no dataloss. My scripts are very simplistic at the moment but here they are: 2 servers Primary Paris Secondary ParisT The StartAgentJobAndWait is a script written by someone else (ta) and just checks the jobs have finished or quits it if it never ends. At the moment I am just using a test database called BOB2 but if I can get it working will pass in the database and job names. from PARIS: /* Disable backup job */ exec msdb..sp_update_job @job_name = 'LSBackup_BOB2', @enabled = 0 exec PARIST.msdb..sp_update_job @job_name = 'LSCopy_PARIS_BOB2', @enabled = 0 exec PARIST.msdb..sp_update_job @job_name = 'LSRestore_PARIS_BOB2', @enabled = 0 exec PARIST.master.dbo.DRStage2 ParisT DRStage2 DECLARE @RetValue varchar (10) EXEC @RetValue = StartAgentJobAndWait LSCopy_PARIS_BOB2 , 2 SELECT ReturnValue=@RetValue if @RetValue = 1 begin print 'The Copy Task completed Succesffuly' END ELSE print 'The Copy task failed, This may or may not be a problem, check restore state of database' SELECT @RetValue = 0 EXEC @RetValue = StartAgentJobAndWait LSRestore_PARIS_BOB2 , 2 SELECT ReturnValue=@RetValue if @RetValue = 1 begin print 'The Restore Task completed Succesffuly' END ELSE print 'The Copy task failed, This may or may not be a problem, check restore state of database' exec PARIS.master.dbo.DRStage3 /* Do the last logship and move it to Trumpington */ BACKUP log "BOB2" to disk='c:\drlogshipping\BOB2.bak' with compression, norecovery EXEC xp_cmdshell 'copy c:\drlogshipping \\192.168.7.11\drlogshipping' EXEC PARIST.master.dbo.DRTransferFinish AS BEGIN restore database "BOB2" from disk='c:\drlogshipping\bob2.bak' with recovery

• Cant kill process on Windows Server 2008!! - Thread in Wait:Executive State

  - by adrian

  I hope someone can help me with our issue we are having. We have a major issue with a process that we can not kill and the only way to get rid of the process is to reboot the machine. I have tried killing it from the normal task manager but no joy. I have tried killing it using the taskkill /F command from a command prompt and no joy. The command reports as sucessful but the process remains. I have tried to start task manager with system rights by calling "psexec -s -i -d taskmgr" and attempting to kill the process but no joy I have tried killing it from Process Explorer but again the process remains. I have tried creating a scheduled task that runs under the SYSTEM name to kill the task but that also does not kill it : schtasks /create /ru system /sc once /st 13:16 /tn test1 /tr "taskkill /F /PID 1576" /it Nothing I do will kill this process. Even logging off and logging back on will not kill this process. Using Process Explorer I notice that there is on stubborn thread that is in the Wait:Executive state. I have tried to kill this thread using Process Explorer but again no joy. We are using Windows Server 2008 R2 64-Bit. The server is brand new and windows is freshly installed. Now heres the thing. We have brought two identical servers from Dell with the same specs and the same OS installed and I can not replicate this issue on the other server. Only on this server, under certain circumstances does this server process hang and can not be restarted! I have also changed the compatability mode by setting it the process to "Windows 2003" but this has not helped. I have noticed in Process Explorer that DEP is turned on but im not sure this has got any bearing on the issue ot not. Please, can someone help??

• VNC Address Book - Window Invisible? Working as intended?

  - by user1445967

  I have VNC Server and VNC Viewer on the same PC with Windows 7 Ultimate x64. Is VNC Address Book supposed to have a main application window? I can't tell if this is bugged or working as intended. When I start VNC Address book, it creates an item in the task list and also an icon in the notification area. If I click the task list item once, nothing happens. If I click again, it disappears from the task list but remains in the notification area**. If I right-click the icon on the notification area, there is an option 'open address book', which if chosen, creates the item in the task list again, with the exact same behavior. If I left or right click on the address book icon, I have ways to connect to servers in the address book. However I have no way to add/remove/edit servers in the address book. **Note that this behavior is identical to that of an application with a main window where there is an option to 'minimize to system tray / notification area'. Only here, no main window is visible, ever. If fixing this problem is beyond the scope of this site, that's fine, but at this point I have no real way to tell if the program is malfunctioning on my pc or if it is far more minimalist than I expected. There appears to be no forum on realvnc.com where I can ask about this, perhaps this is to prevent me from getting any help unless I pay to register?

• FTP Scripting Capabilities

  - by lmg

  I am looking for an FTP client that will allow me to do the following Include a GUI for setting up a number of FTP connections Support FTPS Run unattended on Windows Server 2008 Retry failed transactions Support email Support custom scripts I need to pull files from a few different servers and there are certain calculations that need to be done depending on which server the files come from. I've looked at SmartFTP and it looks like pretty much what I need except I can't get it to run as a Windows Scheduled Task (I currently have some support threads open in their forum). I've also looked at a few other FTP clients (Filezilla, RoboFTP, and AutoFTP (you can find the Windows 7 BSOD in this one!)) that haven't had the capabilities I'm looking for. Right now, I'm looking at WS_FTP and its scripting capabilities. It appears I can create a script to run as a scheduled task, but I can't add the script to a file transfer task. Does anyone have suggestions on how I can do post-transfer processing on the files or better yet how to integrate scripting into the file transfer task? I'm also open to other suggestions for FTP clients as well if you have them! If I can't find a suitable FTP client, custom scripting will just have to do the trick.

• Parallelism in .NET – Part 1, Decomposition

  - by Reed

  The first step in designing any parallelized system is Decomposition.  Decomposition is nothing more than taking a problem space and breaking it into discrete parts.  When we want to work in parallel, we need to have at least two separate things that we are trying to run.  We do this by taking our problem and decomposing it into parts. There are two common abstractions that are useful when discussing parallel decomposition: Data Decomposition and Task Decomposition.  These two abstractions allow us to think about our problem in a way that helps leads us to correct decision making in terms of the algorithms we’ll use to parallelize our routine. To start, I will make a couple of minor points. I’d like to stress that Decomposition has nothing to do with specific algorithms or techniques.  It’s about how you approach and think about the problem, not how you solve the problem using a specific tool, technique, or library.  Decomposing the problem is about constructing the appropriate mental model: once this is done, you can choose the appropriate design and tools, which is a subject for future posts. Decomposition, being unrelated to tools or specific techniques, is not specific to .NET in any way.  This should be the first step to parallelizing a problem, and is valid using any framework, language, or toolset.  However, this gives us a starting point – without a proper understanding of decomposition, it is difficult to understand the proper usage of specific classes and tools within the .NET framework. Data Decomposition is often the simpler abstraction to use when trying to parallelize a routine.  In order to decompose our problem domain by data, we take our entire set of data and break it into smaller, discrete portions, or chunks.  We then work on each chunk in the data set in parallel. This is particularly useful if we can process each element of data independently of the rest of the data.  In a situation like this, there are some wonderfully simple techniques we can use to take advantage of our data.  By decomposing our domain by data, we can very simply parallelize our routines.  In general, we, as developers, should be always searching for data that can be decomposed. Finding data to decompose if fairly simple, in many instances.  Data decomposition is typically used with collections of data.  Any time you have a collection of items, and you’re going to perform work on or with each of the items, you potentially have a situation where parallelism can be exploited.  This is fairly easy to do in practice: look for iteration statements in your code, such as for and foreach. Granted, every for loop is not a candidate to be parallelized.  If the collection is being modified as it’s iterated, or the processing of elements depends on other elements, the iteration block may need to be processed in serial.  However, if this is not the case, data decomposition may be possible. Let’s look at one example of how we might use data decomposition.  Suppose we were working with an image, and we were applying a simple contrast stretching filter.  When we go to apply the filter, once we know the minimum and maximum values, we can apply this to each pixel independently of the other pixels.  This means that we can easily decompose this problem based off data – we will do the same operation, in parallel, on individual chunks of data (each pixel). Task Decomposition, on the other hand, is focused on the individual tasks that need to be performed instead of focusing on the data.  In order to decompose our problem domain by tasks, we need to think about our algorithm in terms of discrete operations, or tasks, which can then later be parallelized. Task decomposition, in practice, can be a bit more tricky than data decomposition.  Here, we need to look at what our algorithm actually does, and how it performs its actions.  Once we have all of the basic steps taken into account, we can try to analyze them and determine whether there are any constraints in terms of shared data or ordering.  There are no simple things to look for in terms of finding tasks we can decompose for parallelism; every algorithm is unique in terms of its tasks, so every algorithm will have unique opportunities for task decomposition. For example, say we want our software to perform some customized actions on startup, prior to showing our main screen.  Perhaps we want to check for proper licensing, notify the user if the license is not valid, and also check for updates to the program.  Once we verify the license, and that there are no updates, we’ll start normally.  In this case, we can decompose this problem into tasks – we have a few tasks, but there are at least two discrete, independent tasks (check licensing, check for updates) which we can perform in parallel.  Once those are completed, we will continue on with our other tasks. One final note – Data Decomposition and Task Decomposition are not mutually exclusive.  Often, you’ll mix the two approaches while trying to parallelize a single routine.  It’s possible to decompose your problem based off data, then further decompose the processing of each element of data based on tasks.  This just provides a framework for thinking about our algorithms, and for discussing the problem.

• SQL SERVER – PAGEIOLATCH_DT, PAGEIOLATCH_EX, PAGEIOLATCH_KP, PAGEIOLATCH_SH, PAGEIOLATCH_UP – Wait Type – Day 9 of 28

  - by pinaldave

  It is very easy to say that you replace your hardware as that is not up to the mark. In reality, it is very difficult to implement. It is really hard to convince an infrastructure team to change any hardware because they are not performing at their best. I had a nightmare related to this issue in a deal with an infrastructure team as I suggested that they replace their faulty hardware. This is because they were initially not accepting the fact that it is the fault of their hardware. But it is really easy to say “Trust me, I am correct”, while it is equally important that you put some logical reasoning along with this statement. PAGEIOLATCH_XX is such a kind of those wait stats that we would directly like to blame on the underlying subsystem. Of course, most of the time, it is correct – the underlying subsystem is usually the problem. From Book On-Line: PAGEIOLATCH_DT Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Destroy mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_EX Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Exclusive mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_KP Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Keep mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_SH Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_UP Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Update mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_XX Explanation: Simply put, this particular wait type occurs when any of the tasks is waiting for data from the disk to move to the buffer cache. ReducingPAGEIOLATCH_XX wait: Just like any other wait type, this is again a very challenging and interesting subject to resolve. Here are a few things you can experiment on: Improve your IO subsystem speed (read the first paragraph of this article, if you have not read it, I repeat that it is easy to say a step like this than to actually implement or do it). This type of wait stats can also happen due to memory pressure or any other memory issues. Putting aside the issue of a faulty IO subsystem, this wait type warrants proper analysis of the memory counters. If due to any reasons, the memory is not optimal and unable to receive the IO data. This situation can create this kind of wait type. Proper placing of files is very important. We should check file system for the proper placement of files – LDF and MDF on separate drive, TempDB on separate drive, hot spot tables on separate filegroup (and on separate disk), etc. Check the File Statistics and see if there is higher IO Read and IO Write Stall SQL SERVER – Get File Statistics Using fn_virtualfilestats. It is very possible that there are no proper indexes on the system and there are lots of table scans and heap scans. Creating proper index can reduce the IO bandwidth considerably. If SQL Server can use appropriate cover index instead of clustered index, it can significantly reduce lots of CPU, Memory and IO (considering cover index has much lesser columns than cluster table and all other it depends conditions). You can refer to the two articles’ links below previously written by me that talk about how to optimize indexes. Create Missing Indexes Drop Unused Indexes Updating statistics can help the Query Optimizer to render optimal plan, which can only be either directly or indirectly. I have seen that updating statistics with full scan (again, if your database is huge and you cannot do this – never mind!) can provide optimal information to SQL Server optimizer leading to efficient plan. Checking Memory Related Perfmon Counters SQLServer: Memory Manager\Memory Grants Pending (Consistent higher value than 0-2) SQLServer: Memory Manager\Memory Grants Outstanding (Consistent higher value, Benchmark) SQLServer: Buffer Manager\Buffer Hit Cache Ratio (Higher is better, greater than 90% for usually smooth running system) SQLServer: Buffer Manager\Page Life Expectancy (Consistent lower value than 300 seconds) Memory: Available Mbytes (Information only) Memory: Page Faults/sec (Benchmark only) Memory: Pages/sec (Benchmark only) Checking Disk Related Perfmon Counters Average Disk sec/Read (Consistent higher value than 4-8 millisecond is not good) Average Disk sec/Write (Consistent higher value than 4-8 millisecond is not good) Average Disk Read/Write Queue Length (Consistent higher value than benchmark is not good) Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All of the discussions of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

• SQL SERVER – PAGELATCH_DT, PAGELATCH_EX, PAGELATCH_KP, PAGELATCH_SH, PAGELATCH_UP – Wait Type – Day 12 of 28

  - by pinaldave

  This is another common wait type. However, I still frequently see people getting confused with PAGEIOLATCH_X and PAGELATCH_X wait types. Actually, there is a big difference between the two. PAGEIOLATCH is related to IO issues, while PAGELATCH is not related to IO issues but is oftentimes linked to a buffer issue. Before we delve deeper in this interesting topic, first let us understand what Latch is. Latches are internal SQL Server locks which can be described as very lightweight and short-term synchronization objects. Latches are not primarily to protect pages being read from disk into memory. It’s a synchronization object for any in-memory access to any portion of a log or data file.[Updated based on comment of Paul Randal] The difference between locks and latches is that locks seal all the involved resources throughout the duration of the transactions (and other processes will have no access to the object), whereas latches locks the resources during the time when the data is changed. This way, a latch is able to maintain the integrity of the data between storage engine and data cache. A latch is a short-living lock that is put on resources on buffer cache and in the physical disk when data is moved in either directions. As soon as the data is moved, the latch is released. Now, let us understand the wait stat type  related to latches. From Book On-Line: PAGELATCH_DT Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Destroy mode. PAGELATCH_EX Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Exclusive mode. PAGELATCH_KP Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Keep mode. PAGELATCH_SH Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Shared mode. PAGELATCH_UP Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Update mode. PAGELATCH_X Explanation: When there is a contention of access of the in-memory pages, this wait type shows up. It is quite possible that some of the pages in the memory are of very high demand. For the SQL Server to access them and put a latch on the pages, it will have to wait. This wait type is usually created at the same time. Additionally, it is commonly visible when the TempDB has higher contention as well. If there are indexes that are heavily used, contention can be created as well, leading to this wait type. Reducing PAGELATCH_X wait: The following counters are useful to understand the status of the PAGELATCH: Average Latch Wait Time (ms): The wait time for latch requests that have to wait. Latch Waits/sec: This is the number of latch requests that could not be granted immediately. Total Latch Wait Time (ms): This is the total latch wait time for latch requests in the last second. If there is TempDB contention, I suggest that you read the blog post of Robert Davis right away. He has written an excellent blog post regarding how to find out TempDB contention. The same blog post explains the terms in the allocation of GAM, SGAM and PFS. If there was a TempDB contention, Paul Randal explains the optimal settings for the TempDB in his misconceptions series. Trace Flag 1118 can be useful but use it very carefully. I totally understand that this blog post is not as clear as my other blog posts. I suggest if this wait stats is on one of your higher wait type. Do leave a comment or send me an email and I will get back to you with my solution for your situation. May the looking at all other wait stats and types together become effective as this wait type can help suggest proper bottleneck in your system. Read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.
