  • CreationName for SSIS 2008 and adding components programmatically

    If you are building SSIS 2008 packages programmatically and adding data flow components, you will probably need to know the creation name of the component to add. I can never find a handy reference when I need one, hence this rather mundane post. See also CreationName for SSS 2005. We start with a very simple snippet for adding a component: // Add the Data Flow Task package.Executables.Add("STOCK:PipelineTask"); // Get the task host wrapper, and the Data Flow task TaskHost taskHost = package.Executables[0] as TaskHost; MainPipe dataFlowTask = (MainPipe)taskHost.InnerObject; // Add OLE-DB source component - ** This is where we need the creation name ** IDTSComponentMetaData90 componentSource = dataFlowTask.ComponentMetaDataCollection.New(); componentSource.Name = "OLEDBSource"; componentSource.ComponentClassID = "DTSAdapter.OLEDBSource.2"; So as you can see the creation name for a OLE-DB Source is DTSAdapter.OLEDBSource.2.

  • SQLAuthority News – Guest Post – Performance Counters Gathering using Powershell

    - by pinaldave
    Laerte Junior Laerte Junior has previously helped me personally to resolve the issue with Powershell installation on my computer. He did awesome job to help. He has send this another wonderful article regarding performance counter for readers of this blog. I really liked it and I expect all of you who are Powershell geeks, you will like the same as well. As a good DBA, you know that our social life is restricted to a few movies over the year and, when possible, a pizza in a restaurant next to your company’s place, of course. So what we have to do is to create methods through which we can facilitate our daily processes to go home early, and eventually have a nice time with our family (and not sleeping on the couch). As a consultant or fixed employee, one of our daily tasks is to monitor performance counters using Perfmom. To be honest, IDE is getting more complicated. To deal with this, I thought a solution using Powershell. Yes, with some lines of Powershell, you can configure which counters to use. And with one more line, you can already start collecting data. Let’s see one scenario: You are a consultant who has several clients and has just closed another project in troubleshooting an SQL Server environment. You are to use Perfmom to collect data from the server and you already have its XML configuration files made with the counters that you will be using- a file for memory bottleneck f, one for CPU, etc. With one Powershell command line for each XML file, you start collecting. The output of such a TXT file collection is set to up in an SQL Server. With two lines of command for each XML, you make the whole process of data collection. Creating an XML configuration File to Memory Counters: Get-PerfCounterCategory -CategoryName "Memory" | Get-PerfCounterInstance  | Get-PerfCounterCounters |Save-ConfigPerfCounter -PathConfigFile "c:\temp\ConfigfileMemory.xml" -newfile Creating an XML Configuration File to Buffer Manager, counters Page lookups/sec, Page reads/sec, Page writes/sec, Page life expectancy: Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters -CounterName "Page*" | Save-ConfigPerfCounter -PathConfigFile "c:\temp\BufferManager.xml" –NewFile Then you start the collection: Set-CollectPerfCounter -DateTimeStart "05/24/2010 08:00:00" -DateTimeEnd "05/24/2010 22:00:00" -Interval 10 -PathConfigFile c:\temp\ConfigfileMemory.xml -PathOutputFile c:\temp\ConfigfileMemory.txt To let the Buffer Manager collect, you need one more counters, including the Buffer cache hit ratio. Just add a new counter to BufferManager.xml, omitting the new file parameter Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters -CounterName "Buffer cache hit ratio" | Save-ConfigPerfCounter -PathConfigFile "c:\temp\BufferManager.xml" And start the collection: Set-CollectPerfCounter -DateTimeStart "05/24/2010 08:00:00" -DateTimeEnd "05/24/2010 22:00:00" -Interval 10 -PathConfigFile c:\temp\BufferManager.xml -PathOutputFile c:\temp\BufferManager.txt You do not know which counters are in the Category Buffer Manager? Simple! Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters Let’s see one output file as shown below. It is ready to bulk insert into the SQL Server. As you can see, Powershell makes this process incredibly easy and fast. Do you want to see more examples?

  • Custom ASP.Net MVC 2 ModelMetadataProvider for using custom view model attributes

    - by SeanMcAlinden
    There are a number of ways of implementing a pattern for using custom view model attributes, the following is similar to something I’m using at work which works pretty well. The classes I’m going to create are really simple: 1. Abstract base attribute 2. Custom ModelMetadata provider which will derive from the DataAnnotationsModelMetadataProvider   Base Attribute MetadataAttribute using System; using System.Web.Mvc; namespace Mvc2Templates.Attributes {     /// <summary>     /// Base class for custom MetadataAttributes.     /// </summary>     public abstract class MetadataAttribute : Attribute     {         /// <summary>         /// Method for processing custom attribute data.         /// </summary>         /// <param name="modelMetaData">A ModelMetaData instance.</param>         public abstract void Process(ModelMetadata modelMetaData);     } } As you can see, the class simple has one method – Process. Process accepts the ModelMetaData which will allow any derived custom attributes to set properties on the model meta data and add items to its AdditionalValues collection.   Custom Model Metadata Provider For a quick explanation of the Model Metadata and how it fits in to the MVC 2 framework, it is basically a set of properties that are usually set via attributes placed above properties on a view model, for example the ReadOnly and HiddenInput attributes. When EditorForModel, DisplayForModel or any of the other EditorFor/DisplayFor methods are called, the ModelMetadata information is used to determine how to display the properties. All of the information available within the model metadata is also available through ViewData.ModelMetadata. The following class derives from the DataAnnotationsModelMetadataProvider built into the mvc 2 framework. I’ve overridden the CreateMetadata method in order to process any custom attributes that may have been placed above a property in a view model.   CustomModelMetadataProvider using System; using System.Collections.Generic; using System.Linq; using System.Web.Mvc; using Mvc2Templates.Attributes; namespace Mvc2Templates.Providers {     public class CustomModelMetadataProvider : DataAnnotationsModelMetadataProvider     {         protected override ModelMetadata CreateMetadata(             IEnumerable<Attribute> attributes,             Type containerType,             Func<object> modelAccessor,             Type modelType,             string propertyName)         {             var modelMetadata = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);               attributes.OfType<MetadataAttribute>().ToList().ForEach(x => x.Process(modelMetadata));               return modelMetadata;         }     } } As you can see, once the model metadata is created through the base method, a check for any attributes deriving from our new abstract base attribute MetadataAttribute is made, the Process method is then called on any existing custom attributes with the model meta data for the property passed in.   Hooking it up The last thing you need to do to hook it up is set the new CustomModelMetadataProvider as the current ModelMetadataProvider, this is done within the Global.asax Application_Start method. Global.asax protected void Application_Start()         {             AreaRegistration.RegisterAllAreas();               RegisterRoutes(RouteTable.Routes);               ModelMetadataProviders.Current = new CustomModelMetadataProvider();         }   In my next post, I’m going to demonstrate a cool custom attribute that turns a textbox into an ajax driven AutoComplete text box. Hope this is useful. Kind Regards, Sean McAlinden.

  • Installer Reboots at "Detecting hardware" (disks and other hardware) on all recent Server Installs

    - by Ryan Rosario
    I have a very frustrating problem with my PC. I cannot install any recent version of Ubuntu Server (or even Desktop) since 9.04 even using the text-based installer. I boot from a USB stick created by Unetbootin (I also tried other methods such as startup disk creator with no difference). On the Server installer, it gets to "Detecting Hardware" (the second one about disks and all other hardware, not network hardware) and then either hangs at 0% (waited 24 hours), or reboots after a minute or two. My system (late 2007): ASUS P5NSLI motherboard Intel Core 2 Duo E6600 2.4Ghz 2 x 1GB Corsair 667MHz RAM nVidia GeForce 6600 I have unplugged everything (including the only hard disk, CD-ROMs and floppy). I have only one stick of RAM (tried each one to no avail) and am booting the installer from a USB stick (booting from CD-ROM yields the same problem). I also tried several of the boot options (nomodeset, nousb, acpi=off, noapic, i915.modeset=1/0, xforcevesa) in all combinations) to no avail. The only active parts of my system are the video card, mouse, keyboard and USB stick. I have also updated the BIOS to the most recent version. (FWIW, on the Desktop installer, I get a black screen after hitting the Install option.) Even after removing "quiet" I am unable to see what kernel panic is occurring (or not occurring) to cause the install to crash. I am only able to save the debug logs via a simple webserver in the installer. After the last line (I repeatedly refreshed), the server stops responding and the installer hangs or reboots: Jan 2 01:04:03 main-menu[302]: INFO: Menu item 'disk-detect' selected Jan 2 01:04:04 kernel: [ 309.154372] sata_nv 0000:00:0e.0: version 3.5 Jan 2 01:04:04 kernel: [ 309.154409] sata_nv 0000:00:0e.0: Using SWNCQ mode Jan 2 01:04:04 kernel: [ 309.154531] sata_nv 0000:00:0e.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.164442] scsi0 : sata_nv Jan 2 01:04:04 kernel: [ 309.167610] scsi1 : sata_nv Jan 2 01:04:04 kernel: [ 309.167762] ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xd400 irq 10 Jan 2 01:04:04 kernel: [ 309.167774] ata2: SATA max UDMA/133 cmd 0x970 ctl 0xb70 bmdma 0xd408 irq 10 Jan 2 01:04:04 kernel: [ 309.167948] sata_nv 0000:00:0f.0: Using SWNCQ mode Jan 2 01:04:04 kernel: [ 309.168071] sata_nv 0000:00:0f.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.171931] scsi2 : sata_nv Jan 2 01:04:04 kernel: [ 309.173793] scsi3 : sata_nv Jan 2 01:04:04 kernel: [ 309.173943] ata3: SATA max UDMA/133 cmd 0x9e0 ctl 0xbe0 bmdma 0xe800 irq 11 Jan 2 01:04:04 kernel: [ 309.173954] ata4: SATA max UDMA/133 cmd 0x960 ctl 0xb60 bmdma 0xe808 irq 11 Jan 2 01:04:04 kernel: [ 309.174061] pata_amd 0000:00:0d.0: version 0.4.1 Jan 2 01:04:04 kernel: [ 309.174160] pata_amd 0000:00:0d.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.177045] scsi4 : pata_amd Jan 2 01:04:04 kernel: [ 309.178628] scsi5 : pata_amd Jan 2 01:04:04 kernel: [ 309.178801] ata5: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xf000 irq 14 Jan 2 01:04:04 kernel: [ 309.178811] ata6: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xf008 irq 15 Jan 2 01:04:04 net/hw-detect.hotplug: Detected hotpluggable network interface eth0 Jan 2 01:04:04 net/hw-detect.hotplug: Detected hotpluggable network interface lo Jan 2 01:04:04 kernel: [ 309.485062] ata3: SATA link down (SStatus 0 SControl 300) Jan 2 01:04:04 kernel: [ 309.633094] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Jan 2 01:04:04 kernel: [ 309.641647] ata1.00: ATA-8: ST31000528AS, CC38, max UDMA/133 Jan 2 01:04:04 kernel: [ 309.641658] ata1.00: 1953525168 sectors, multi 1: LBA48 NCQ (depth 31/32) Jan 2 01:04:04 kernel: [ 309.657614] ata1.00: configured for UDMA/133 Jan 2 01:04:04 kernel: [ 309.657969] scsi 0:0:0:0: Direct-Access ATA ST31000528AS CC38 PQ: 0 ANSI: 5 Jan 2 01:04:04 kernel: [ 309.658482] sd 0:0:0:0: Attached scsi generic sg0 type 0 Jan 2 01:04:04 kernel: [ 309.658588] sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) Jan 2 01:04:04 kernel: [ 309.658812] sd 0:0:0:0: [sda] Write Protect is off Jan 2 01:04:04 kernel: [ 309.658823] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 Jan 2 01:04:04 kernel: [ 309.658918] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jan 2 01:04:04 kernel: [ 309.675630] sda: sda1 sda2 Jan 2 01:04:04 kernel: [ 309.676440] sd 0:0:0:0: [sda] Attached SCSI disk Jan 2 01:04:05 kernel: [ 309.969102] ata2: SATA link down (SStatus 0 SControl 300) Jan 2 01:04:05 kernel: [ 310.281137] ata4: SATA link down (SStatus 0 SControl 300) Anybody have any additional ideas I could try?

  • JMX Based Monitoring - Part Three - Web App Server Monitoring

    - by Anthony Shorten
    In the last blog entry I showed a technique for integrating a JMX console with Oracle WebLogic which is a standard feature of Oracle WebLogic 11g. Customers on other Web Application servers and other versions of Oracle WebLogic can refer to the documentation provided with the server to do a similar thing. In this blog entry I am going to discuss a new feature that is only present in Oracle Utilities Application Framework 4 and above that allows JMX to be used for management and monitoring the Oracle Utilities Web Applications. In this case JMX can be used to perform monitoring as well as provide the management of the cache. In Oracle Utilities Application Framework you can enable Web Application Server JMX monitoring that is unique to the framework by specifying a JMX port number in RMI Port number for JMX Web setting and initial credentials in the JMX Enablement System User ID and JMX Enablement System Password configuration options. These options are available using the configureEnv[.sh] -a utility. Once this is information is supplied a number of configuration files are built (by the initialSetup[.sh] utility) to configure the facility: spl.properties - contains the JMX URL, the security configuration and the mbeans that are enabled. For example, on my demonstration machine: spl.runtime.management.rmi.port=6740 spl.runtime.management.connector.url.default=service:jmx:rmi:///jndi/rmi://localhost:6740/oracle/ouaf/webAppConnector jmx.remote.x.password.file=scripts/ouaf.jmx.password.file jmx.remote.x.access.file=scripts/ouaf.jmx.access.file ouaf.jmx.com.splwg.base.support.management.mbean.JVMInfo=enabled ouaf.jmx.com.splwg.base.web.mbeans.FlushBean=enabled ouaf.jmx.* files - contain the userid and password. The default setup uses the JMX default security configuration. You can use additional security features by altering the spl.properties file manually or using a custom template. For more security options see the JMX Site. Once it has been configured and the changes reflected in the product using the initialSetup[.sh] utility the JMX facility can be used. For illustrative purposes, I will use jconsole but any JSR160 complaint browser or client can be used (with the appropriate configuration). Once you start jconsole (ensure that splenviron[.sh] is executed prior to execution to set the environment variables or for remote connection, ensure java is in your path and jconsole.jar in your classpath) you specify the URL in the spl.management.connnector.url.default entry and the credentials you specified in the jmx.remote.x.* files. Remember these are encrypted by default so if you try and view the file you may be able to decipher it visually. For example: There are three Mbeans available to you: flushBean - This is a JMX replacement for the jsp versions of the flush utilities provided in previous releases of the Oracle Utilities Application Framework. You can manage the cache using the provided operations from JMX. The jsp versions of the flush utilities are still provided, for backward compatibility, but now are authorization controlled. JVMInfo - This is a JMX replacement for the jsp version of the JVMInfo screen used by support to get a handle on JVM information. This information is environmental not operational and is used for support purposes. The jsp versions of the JVMInfo utilities are still provided, for backward compatibility, but now is also authorization controlled. JVMSystem - This is an implementation of the Java system MXBeans for use in monitoring. We provide our own implementation of the base Mbeans to save on creating another JMX configuration for internal monitoring and to provide a consistent interface across platforms for the MXBeans. This Mbean is disabled by default and can be enabled using the enableJVMSystemBeans operation. This Mbean allows for the monitoring of the ClassLoading, Memory, OperatingSystem, Runtime and the Thread MX beans. Refer to the Server Administration Guides provided with your product and the Technical Best Practices Whitepaper for information about individual statistics. The Web Application Server JMX monitoring allows greater visibility for monitoring and management of the Oracle Utilities Application Framework application from jconsole or any JSR160 compliant JMX browser or JMX console.

  • How to read oom-killer syslog messages?

    - by Grant
    I have a Ubuntu 12.04 server which sometimes dies completely - no SSH, no ping, nothing until it is physically rebooted. After the reboot, I see in syslog that the oom-killer killed, well, pretty much everything. There's a lot of detailed memory usage information in them. How do I read these logs to see what caused the OOM issue? The server has far more memory than it needs, so it shouldn't be running out of memory.

  • SQL SERVER – SOS_SCHEDULER_YIELD – Wait Type – Day 8 of 28

    - by pinaldave
    This is a very interesting wait type and quite often seen as one of the top wait types. Let us discuss this today. From Book On-Line: Occurs when a task voluntarily yields the scheduler for other tasks to execute. During this wait the task is waiting for its quantum to be renewed. SOS_SCHEDULER_YIELD Explanation: SQL Server has multiple threads, and the basic working methodology for SQL Server is that SQL Server does not let any “runnable” thread to starve. Now let us assume SQL Server OS is very busy running threads on all the scheduler. There are always new threads coming up which are ready to run (in other words, runnable). Thread management of the SQL Server is decided by SQL Server and not the operating system. SQL Server runs on non-preemptive mode most of the time, meaning the threads are co-operative and can let other threads to run from time to time by yielding itself. When any thread yields itself for another thread, it creates this wait. If there are more threads, it clearly indicates that the CPU is under pressure. You can fun the following DMV to see how many runnable task counts there are in your system. SELECT scheduler_id, current_tasks_count, runnable_tasks_count, work_queue_count, pending_disk_io_count FROM sys.dm_os_schedulers WHERE scheduler_id < 255 GO If you notice a two-digit number in runnable_tasks_count continuously for long time (not once in a while), you will know that there is CPU pressure. The two-digit number is usually considered as a bad thing; you can read the description of the above DMV over here. Additionally, there are several other counters (%Processor Time and other processor related counters), through which you can refer to so you can validate CPU pressure along with the method explained above. Reducing SOS_SCHEDULER_YIELD wait: This is the trickiest part of this procedure. As discussed, this particular wait type relates to CPU pressure. Increasing more CPU is the solution in simple terms; however, it is not easy to implement this solution. There are other things that you can consider when this wait type is very high. Here is the query where you can find the most expensive query related to CPU from the cache Note: The query that used lots of resources but is not cached will not be caught here. SELECT SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1, ((CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(qt.TEXT) ELSE qs.statement_end_offset END - qs.statement_start_offset)/2)+1), qs.execution_count, qs.total_logical_reads, qs.last_logical_reads, qs.total_logical_writes, qs.last_logical_writes, qs.total_worker_time, qs.last_worker_time, qs.total_elapsed_time/1000000 total_elapsed_time_in_S, qs.last_elapsed_time/1000000 last_elapsed_time_in_S, qs.last_execution_time, qp.query_plan FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp ORDER BY qs.total_worker_time DESC -- CPU time You can find the most expensive queries that are utilizing lots of CPU (from the cache) and you can tune them accordingly. Moreover, you can find the longest running query and attempt to tune them if there is any processor offending code. Additionally, pay attention to total_worker_time because if that is also consistently higher, then  the CPU under too much pressure. You can also check perfmon counters of compilations as they tend to use good amount of CPU. Index rebuild is also a CPU intensive process but we should consider that main cause for this query because that is indeed needed on high transactions OLTP system utilized to reduce fragmentations. 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.

  • How to Browse Without a Trace with an Ubuntu Live CD

    - by Trevor Bekolay
    No matter how diligently you clear your cache and erase your history, web browsing leaves traces on your computer. If you need keep your browsing private, then an Ubuntu Live CD is the answer. The key to this trick is that the Live CD environment runs completely in RAM, so things like your cache, cookies, and history don’t get saved to a persistent storage location. On a hard drive, even deleted files can be recovered, but once a computer is turned off the data stored in RAM is unrecoverable. In addition, since the Ubuntu Live CD environment is the same no matter what computer you use it on, there’s very little identifying information that a website can use to track you! The first step is to either burn an Ubuntu Live CD, or prepare a non-persistent Ubuntu USB flash drive. Ubuntu treats non-persistent flash drives like CDs, so files will not be written to it, but if you’re paranoid, then using a physical CD ensures that nothing gets written to a storage device. Boot up from the CD or flash drive, and choose to Run Ubuntu from the CD or flash drive if prompted (for more detailed instructions on booting from a CD or USB drive, see this article, or our guide on booting from a flash drive even if your BIOS won’t let you). Once the graphical Ubuntu environment comes up, you can click on the Firefox icon at the top of the screen to start browsing. If your browsing requires Flash, then you can install it by clicking on System at the top-left of the screen, then Administration > Synaptic Package Manager. Click on Settings at the top of the Synaptic window, and then select Repositories. Add a check in the checkbox with the label ending in “multiverse”. Click Close. Click the Reload button in the main Synaptic window. The list of available packages will reload. When they’ve reloaded, type “restricted” in the Quick search box. Right-click on ubuntu-restricted-extras and select Mark for Installation. It will note a number of other packages that will be installed. This list includes audio and video codecs, so after installing these, you should be able to play downloaded movies and songs. Click Mark to accept the installation of these other packages. Once you return to the main Synaptic window, click the Apply button and go through the dialogs to finish the installation of Flash and the other useful packages. If you open up Firefox now, you’ll have no problems using websites that use Flash. When you’re done browsing and shut down or restart your computer, all traces of your web browsing will be gone. It’s a bit of work compared to just using a privacy-centric browser, but if it’s very important that your browsing leave no traces on your hard drive, an Ubuntu Live CD is your best bet.

  • Customize Team Build 2010 – Part 12: How to debug my custom activities

    In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application       Developers are “spoilt” persons who expect to be able to have easy debugging experiences for every technique they work with. So they also expect it when developing custom activities for the build process template. This post describes how you can debug your custom activities without having to develop on the build server itself. Remote debugging prerequisites The prerequisite for these steps are to install the Microsoft Visual Studio Remote Debugging Monitor. You can find information how to install this at http://msdn.microsoft.com/en-us/library/bt727f1t.aspx. I chose for the option to run the remote debugger on the build server from a file share. Debugging symbols prerequisites To be able to start the debugging, you need to have the pdb files on the buildserver together with the assembly. The pdb must have been build with Full Debug Info. Steps In my setup I have a development machine and a build server. To setup the remote debugging, I performed the following steps Locate on your development machine the folder C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger Create a share for the Remote Debugger folder. Make sure that the share (and the folder) has the correct permissions so the user on the build server has access to the share. On the build server go to the shared “Remote Debugger” folder Start msvsmon.exe which is located in the folder that represents the platform of the build server. This will open a winform application like   Go back to your development machine and open the BuildProcess solution. Start the Attach to process command (Ctrl+Alt+P) Type in the Qualifier the name of the build server. In my case the user account that has started the msvsmon is another user then the user on my development machine. In that case you have to type the qualifier in the format that is shown in the Remote Debugging Monitor (in my case LOCAL\Administrator@TFSLAB) and confirm it by pressing <Enter> Since the build service is running with other credentials, check the option “Show processes from all users”. Now the Attach to process dialog shows the TFSBuildServiceHost process Set the breakpoint in the activity you want to debug and kick of a build. Be aware that when you attach to the TFSBuildServiceHost that you debug every single build that is run by this windows service, so make sure you don’t debug the build server that is in production! You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.

  • Throttling in OSB

    - by Knut Vatsendvik
    Technorati Tags: soa,integration,osb,throttling,overload protection A common problem with integration is the risk of overloading a particular web service. When the capacity of a web service is reached and it continues to accept connections, it will most likely start to deteriorate. Fortunately there are 2 techniques, with Oracle Service Bus, that you can apply for protecting this from happening. You can either limit the concurrent number of requests for a Business Service (outbound requests) or you can limit the number of threads processing the requests for a Proxy Service (inbound requests). Limiting the Concurrent Number of Requests Limiting the concurrent requests for a Business Service cannot be set at design time so you have to use the built-in Oracle Service Bus Administration Console to do it (/sbconsole). Follow these steps to enable it: In Change Center, click Create to start a new Session Select Project Explorer, and navigate to the Business Service you want to limit Select the Operational Settings tab of the View a Business Service page In this tab, under Throttling, select the Enable check box. By enabling throttling you Specify a value for Maximum Concurrency Specify a positive integer value for Throttling Queue to backlog messages that has exceeded the message concurrency limit Specify the maximum time in milliseconds for Message Expiration a message can spend in Throttling Queue Click Update Click Active in Change Center to active the new settings If you re-publish the service, it will not overwrite the settings. Only if the resource is renamed or moved, it will. Please note that a throttling queue is an in-memory queue. Messages that are placed in this queue are not recoverable when a server fails or when you restart a server. Limiting the Number of Threads A better approach, in my opinion, is to limit the number of threads that can work with request. Follow these steps to do it: Open the WebLogic Server Console (/console) In Change Center, click Create to start a new Session In the left pane expand Environment and select Work Managers In the Global Work Managers page, click New    Click the Work Manager radio button, then click Next Enter a Name for the new Work Manager, and click Next In the Available Targets list, select server instances or clusters on which you will deploy applications that reference the Work Manager Click Finish. The new Work Manager now appears in the Global Work Managers page. Select the new Work Manager Right next to the Maximum Threads Constraint drop-down box, click New   Click the Maximum Threads Constraint radio button, then click Next Enter a Name and a thread Count to be the maximum size to allocate for requests. Click Next  In the Available Targets list, select server instances or clusters on which you will deploy applications that reference the Work Manager Click Finish Click Save Click Active in Change Center to active your changes.  A restart may be necessary.   Puh! Almost there. Start a new session. Go to the Service Bus Console (/sbconsole) and find your consuming Proxy Service. Click the Edit button of the Transport Configuration tab. Click Next Set the Dispatch Policy to the new Work Manager Click Last Click Save Click Active in Change Center to active your changes.

  • Understanding Collabnet&rsquo;s LDAP binding

    - by Robert May
    We want to use both subversion usernames and passwords as well as Active Directory for our authentication on our Collabnet subversion server. This has proven to be more of a challenge than we thought, mostly because Collabnet’s documentation is pretty poor. To supplement that documentation, I add my own. The first thing to understand is that the attribute that you specify in the LDAP Login Attribute ONLY applies to lookups done for the user.  It does NOT apply to the LDAP Bind DN field.  Second, know that the debug logs (error is the one you want) don’t give you debug information for the bind DN, just the login attempts.  Third, by default, Active Directory does not allow anonymous binds, so you MUST put in a user that has the authority to query the Active Directory ldap. Because of these items, the values to set in those fields can be somewhat confusing.  You’ll want to have ADSI Edit handy (I also used ldp, which is installed by default on server 2008), since ADSI Edit can help you find stuff in your active directory.  Be careful, you can also break stuff. Here’s what should go into those fields. LDAP Security Level:  Should be set to None LDAP Server Host:  Should be set to the full name of a domain controller in your domain.  For example, dc.mydomain.com LDAP Server Port:  Should be set to 3268.  The default port of 389 will only query that specific server, not the global catalog.  By setting it to 3268, the global catalog will be queried, which is probably what you want. LDAP Base DN:  Should be set to the location where you want the search for users to begin.  By default, the search scope is set to sub, so all child organizational units below this setting will be searched.  In my case, I had created an OU specifically for users for group policies.  My value ended up being:  OU=MyOu,DC=domain,DC=org.   However, if you’re pointing it to the default Users folder, you may end up with something like CN=Users,DC=domain,DC=org (or com or whatever).  Again, use ADSI edit and use the Distinguished Name that it shows. LDAP Bind DN:  This needs to be the Distinguished Name of the user that you’re going to use for binding (i.e. the user you’ll be impersonating) for doing queries.  In my case, it ended up being CN=svn svn,OU=MyOu,DC=domain,DC=org.  Why the double svn, you might ask?  That’s because the first and last name fields are set to svn and by default, the distinguished name is the first and last name fields!  That’s important.  Its NOT the username or account name!  Again, use ADSI edit, browse to the username you want to use, right click and select properties, and then search the attributes for the Distinguished Name.  Once you’ve found that, select it and click View and you can copy and paste that into this field. LDAP Bind Password:  This is the password for the account in the Bind DN LDAP login Attribute: sAMAccountName.  If you leave this blank, uid is used, which may not even be set.  This tells it to use the Account Name field that’s defined under the account tab for users in Active Directory Users and Computers.  Note that this attribute DOES NOT APPLY to the LDAP Bind DN.  You must use the full distinguished name of the bind DN.  This attribute allows users to type their username and password for authentication, rather than typing their distinguished name, which they probably don’t know. LDAP Search Scope:  Probably should stay at sub, but could be different depending on your situation. LDAP Filter:  I left mine blank, but you could provide one to limit what you want to see.  LDP would be helpful for determining what this is. LDAP Server Certificate Verification:  I left it checked, but didn’t try it without it being checked. Hopefully, this will save some others pain when trying to get Collabnet setup.

  • C# 4.0: COM Interop Improvements

    - by Paulo Morgado
    Dynamic resolution as well as named and optional arguments greatly improve the experience of interoperating with COM APIs such as Office Automation Primary Interop Assemblies (PIAs). But, in order to alleviate even more COM Interop development, a few COM-specific features were also added to C# 4.0. Ommiting ref Because of a different programming model, many COM APIs contain a lot of reference parameters. These parameters are typically not meant to mutate a passed-in argument, but are simply another way of passing value parameters. Specifically for COM methods, the compiler allows to declare the method call passing the arguments by value and will automatically generate the necessary temporary variables to hold the values in order to pass them by reference and will discard their values after the call returns. From the point of view of the programmer, the arguments are being passed by value. This method call: object fileName = "Test.docx"; object missing = Missing.Value; document.SaveAs(ref fileName, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); can now be written like this: document.SaveAs("Test.docx", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); And because all parameters that are receiving the Missing.Value value have that value as its default value, the declaration of the method call can even be reduced to this: document.SaveAs("Test.docx"); Dynamic Import Many COM methods accept and return variant types, which are represented in the PIAs as object. In the vast majority of cases, a programmer calling these methods already knows the static type of a returned object form the context of the call, but has to explicitly perform a cast on the returned values to make use of that knowledge. These casts are so common that they constitute a major nuisance. To make the developer’s life easier, it is now possible to import the COM APIs in such a way that variants are instead represented using the type dynamic which means that COM signatures have now occurrences of dynamic instead of object. This means that members of a returned object can now be easily accessed or assigned into a strongly typed variable without having to cast. Instead of this code: ((Excel.Range)(excel.Cells[1, 1])).Value2 = "Hello World!"; this code can now be used: excel.Cells[1, 1] = "Hello World!"; And instead of this: Excel.Range range = (Excel.Range)(excel.Cells[1, 1]); this can be used: Excel.Range range = excel.Cells[1, 1]; Indexed And Default Properties A few COM interface features are still not available in C#. On the top of the list are indexed properties and default properties. As mentioned above, these will be possible if the COM interface is accessed dynamically, but will not be recognized by statically typed C# code. No PIAs – Type Equivalence And Type Embedding For assemblies indentified with PrimaryInteropAssemblyAttribute, the compiler will create equivalent types (interfaces, structs, enumerations and delegates) and embed them in the generated assembly. To reduce the final size of the generated assembly, only the used types and their used members will be generated and embedded. Although this makes development and deployment of applications using the COM components easier because there’s no need to deploy the PIAs, COM component developers are still required to build the PIAs.

  • Assign highest priority to my local repository

    - by Anwar Shah
    Original question was : "How to assign highest priority to local repository without using sources.list file" I have setup a local repository with packages I downloaded. I use it to avoid downloading the same packages over the Internet, when I need to reinstall my Ubuntu. It is a basic repository, created with apt-ftparchive packages . > Packages. I made this a trusted repository to avoid "unauthenticated repository" warning. (When you have a untrusted repository, apt or synaptic try to download the same packages over the Internet, 'cause it is trusted). I have been using this local repository for at least 1 years. But I have to always put my local repository line at the top of the sources.list file to use this. But this is annoying, since I must open a terminal and do some typing on it every time I reinstall Ubuntu, though there is a better tool software-properties-gtk. I cannot use this tool since it place the source line at the end of `sources.list. And the real problem is that, the apt or synaptic always download a package from the source which is mentioned earlier, without inspecting whether the packages are already available in the local repository. So, I have no choice but to place the local source at the top of sources.list doing terminal (I actually don't hate terminal, but I need a solution) . I have tried this method. But this does not help me. My preference file is this in /etc/apt/preferences.d/local-pin-900 Package: * Pin: release o=Local,n=ubuntu-local Pin-Priority: 900 My release file is this Origin: Local Label: Local-Ubuntu Description: Local Ubuntu Repository Codename: ubuntu-local MD5Sum: ed43222856d18f389c637ac3d7dd6f85 1043412 Packages d41d8cd98f00b204e9800998ecf8427e 0 Sources When I enable the apt-preference, the apt-cache policy correctly shows the preference, e.g. It shows the local repository has the highest priority. But when I do this sudo apt-get install <package-name>, apt tries to download it from Internet. But when I place my local-repo at the top, it installs from local repository. So, My question is - 'Is it possible to force apt to use local repository when the package is available in local repository, without explicitly placing "the local source" at the top of my repository list (e.g sources.list file) ?' Edit: output of apt-cache policy $package_name is as follows nautilus-wipe: Installed: (none) Candidate: 0.1.1-2 Version table: 0.1.1-2 0 500 http://archive.ubuntu.com/ubuntu/ precise/universe i386 Packages 900 file:/media/Main/Linux-Software/Ubuntu/Precise/ Packages It is showing that my local repository has higher preference, though it is not the one which comes first in sources.list file. Here is the output of apt-get install nautilus-wipe Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: nautilus-wipe 0 upgraded, 1 newly installed, 0 to remove and 131 not upgraded. Need to get 30.7 kB of archives. After this operation, 150 kB of additional disk space will be used. 'http://archive.ubuntu.com/ubuntu/pool/universe/n/nautilus-wipe/nautilus-wipe_0.1.1-2_i386.deb' nautilus-wipe_0.1.1-2_i386.deb 30730 MD5Sum:7d497b8dfcefe1c0b51a45f3b0466994 It is still trying to get the file from Internet, though I think it should be happy with the local one.

  • MySQL is running VERY slow

    - by user1032531
    I have two servers: a VPS and a laptop. I recently re-built both of them, and MySQL is running about 20 times slower on the laptop. Both servers used to run CentOS 5.8 and I think MySQL 5.1, and the laptop used to do great so I do not think it is the hardware. For the VPS, my provider installed CentOS 6.4, and then I installed MySQL 5.1.69 using yum with the CentOS repo. For the laptop, I installed CentOS 6.4 basic server and then installed MySQL 5.1.69 using yum with the CentOS repo. my.cnf for both servers are identical, and I have shown below. For both servers, I've also included below the output from SHOW VARIABLES; as well as output from sysbench, file system information, and cpu information. I have tried adding skip-name-resolve, but it didn't help. The matrix below shows the SHOW VARIABLES output from both servers which is different. Again, MySQL was installed the same way, so I do not know why it is different, but it is and I think this might be why the laptop is executing MySQL so slowly. Why is the laptop running MySQL slowly, and how do I fix it?

  • Browser History ASP.Net AJAX: Microsoft.Web.Preview

    - by Narendra Tiwari
    I remember in 2006 we were working on a portal for our client Venetian, Las Vegas and the portal is full of AJAX features. One of my friend facing a challange to retain browser history with all AJAX operation. In terms of user experience it is an important aspect which could not be avoided in that scenario. Well that time we have made some workarounds to achieve the same but that may not be the perfect solution. Ok.. Now with Microsoft AJAX there are a lot of such features can be achieved with optimum efficiency. Microsoft AJAX has grown its features over the past few years. Microsoft.Web.Preview.dll is an addon in conjunction with ASP.Net AJAX. It contains a control named "History" for that purpose. Source code:- http://download.microsoft.com/download/8/3/1/831ffcd7-c571-4075-b8fa-6ff678794f60/CS-ASP-ASPBrowserHistoryinAJAX_cs.zip Below is a small sample to demonstrate the control. 1/ Get dll from the above source code bin, and add reference to your web application. 2/ Rightclick on toolbox panel and Choose Item, browse assembly. now you will be able to see History control. 3/ Add below section group in web.config under <configSections> <sectionGroup name="microsoft.web.preview" type="Microsoft.Web.Preview.Configuration.PreviewSectionGroup, Microsoft.Web.Preview"> <section name="search" type="Microsoft.Web.Preview.Configuration.SearchSection, Microsoft.Web.Preview" requirePermission="false" allowDefinition="MachineToApplication"/> <section name="searchSiteMap" type="Microsoft.Web.Preview.Configuration.SearchSiteMapSection, Microsoft.Web.Preview" requirePermission="false" allowDefinition="MachineToApplication"/> <section name="diagnostics" type="Microsoft.Web.Preview.Configuration.DiagnosticsSection, Microsoft.Web.Preview" requirePermission="false" allowDefinition="MachineToApplication"/> </sectionGroup> 4/ Now create a simple webpage a textbox (txt1), button (btn1)  in an updatePanel with History control (History1). We will fill in text box and post the fom by clicking button a few times then verify if the browse history is retained. Remember button and textbox must be inside UpdatePanel and History control outside the UpdatePanel. <%@Page Language="C#" AutoEventWireup="true" CodeFile="History.aspx.cs" Inherits="History" %> <%@ Register Assembly="Microsoft.Web.Preview" Namespace="Microsoft.Web.Preview.UI.Controls" TagPrefix="cc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager> <div> <cc1:History ID="History1" runat="server" OnNavigate="History1_Navigate"> </cc1:History> <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <asp:TextBox ID="txt1" runat="server"></asp:TextBox><br /> <asp:Button ID="btn1" runat="server" Text="Test" OnClick="btn1_Click" /> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="History1" /> </Triggers> </asp:UpdatePanel> </div> </form> </body> </html> 5/ Below code to add the textbox value in history everytime we post back using btn1 click.  protected void btn1_Click(object sender, EventArgs e) { History1.AddHistoryPoint("txtState",txt1.Text); } 6/ and finally Navigate event of History control protected void History1_Navigate(object sender, Microsoft.Web.Preview.UI.Controls.HistoryEventArgs args) { string strState = string.Empty; if (args.State.ContainsKey("txtState")) { strState = (string)args.State["txtState"]; } txt1.Text = strState; } Now all set to go :) Reference: http://www.dotnetglobe.com/2008/08/using-asp.html

  • A temporary disagreement

    - by Tony Davis
    Last month, Phil Factor caused a furore amongst some MVPs with an article that attempted to offer simple advice to developers regarding the use of table variables, versus local and global temporary tables, in their code. Phil makes clear that the table variables do come with some fairly major limitations.no distribution statistics, no parallel query plans for queries that modify table variables.but goes on to suggest that for reasonably small-scale strategic uses, and with a bit of due care and testing, table variables are a "good thing". Not everyone shares his opinion; in fact, I imagine he was rather aghast to learn that there were those felt his article was akin to pulling the pin out of a grenade and tossing it into the database; table variables should be avoided in almost all cases, according to their advice, in favour of temp tables. In other words, a fairly major feature of SQL Server should be more-or-less 'off limits' to developers. The problem with temp tables is that, because they are scoped either in the procedure or the connection, it is easy to allow them to hang around for too long, eating up precious memory and bulking up the shared tempdb database. Unless they are explicitly dropped, global temporary tables, and local temporary tables created within a connection rather than within a stored procedure, will persist until the connection is closed or, with connection pooling, until the connection is reused. It's also quite common with ASP.NET applications to have connection leaks, as Bill Vaughn explains in his chapter in the "SQL Server Deep Dives" book, meaning that the web page exits without closing the connection object, maybe due to an error condition. This will then hang around in the heap for what might be hours before picked up by the garbage collector. Table variables are much safer in this regard, since they are batch-scoped and so are cleaned up automatically once the batch is complete, which also means that they are intuitive to use for the developer because they conform to scoping rules that are closer to those in procedural code. On the surface then, an ideal way to deal with issues related to tempdb memory hogging. So why did Phil qualify his recommendation to use Table Variables? This is another of those cases where, like scalar UDFs and table-valued multi-statement UDFs, developers can sometimes get into trouble with a relatively benign-looking feature, due to way it's been implemented in SQL Server. Once again the biggest problem is how they are handled internally, by the SQL Server query optimizer, which can make very poor choices for JOIN orders and so on, in the absence of statistics, especially when joining to tables with highly-skewed data. The resulting execution plans can be horrible, as will be the resulting performance. If the JOIN is to a large table, that will hurt. Ideally, Microsoft would simply fix this issue so that developers can't get burned in this way; they've been around since SQL Server 2000, so Microsoft has had a bit of time to get it right. As I commented in regard to UDFs, when developers discover issues like with such standard features, the database becomes an alien planet to them, where death lurks around each corner, and they continue to avoid these "killer" features years after the problems have been eventually resolved. In the meantime, what is the right approach? Is it to say "hammers can kill, don't ever use hammers", or is it to try to explain, as Phil's article and follow-up blog post have tried to do, what the feature was intended for, why care must be applied in its use, and so enable developers to make properly-informed decisions, without requiring them to delve deep into the inner workings of SQL Server? Cheers, Tony.

  • ls -l freezes terminal locally and remotely

    - by Jakobud
    I've been reading other SF threads regarding ls not returning results or freezing and stalling terminal sessions and it appears they usually the fault of network problems. My problem however, occurs both over remote SSH sessions but also if I am physically at the server itself... I just installed CentOS 5.4 on one of our servers. I'm setting up some rdiff-backup scripts and when I downloaded librsync and untared it, thats when I started seeing some weird behavior with ls -l. wget http://sourceforge.net/projects/librsync/files/librsync/0.9.7/librsync-0.9.7.tar.gz/download /tmp cd /tmp tar -xzf librsync-0.9.7.tar.gz Simple enough. To view the files in this directory I did this: ls results: librsync-0.9.7 librsync-0.9.7.tar.gz Now, if I ls -l, my terminal freezes. I have to re-ssh in to keep going. After reading SF threads, I thought it was network related. So I was extremely surprised to go sit down at the server itself and see the exact same thing happen... So its obviously not a network issues. Even if I ls /tmp/librsync-0.9.7, my terminal freezes just the same... Next I did an strace and got this (warning: wall of text coming....): strace ls -l /tmp execve("/bin/ls", ["ls", "-l", "/tmp"], [/* 21 vars */]) = 0 brk(0) = 0x1c521000 mmap(NULL, 4096,

  • Merge sort versus quick sort performance

    - by Giorgio
    I have implemented merge sort and quick sort using C (GCC 4.4.3 on Ubuntu 10.04 running on a 4 GB RAM laptop with an Intel DUO CPU at 2GHz) and I wanted to compare the performance of the two algorithms. The prototypes of the sorting functions are: void merge_sort(const char **lines, int start, int end); void quick_sort(const char **lines, int start, int end); i.e. both take an array of pointers to strings and sort the elements with index i : start <= i <= end. I have produced some files containing random strings with length on average 4.5 characters. The test files range from 100 lines to 10000000 lines. I was a bit surprised by the results because, even though I know that merge sort has complexity O(n log(n)) while quick sort is O(n^2), I have often read that on average quick sort should be as fast as merge sort. However, my results are the following. Up to 10000 strings, both algorithms perform equally well. For 10000 strings, both require about 0.007 seconds. For 100000 strings, merge sort is slightly faster with 0.095 s against 0.121 s. For 1000000 strings merge sort takes 1.287 s against 5.233 s of quick sort. For 5000000 strings merge sort takes 7.582 s against 118.240 s of quick sort. For 10000000 strings merge sort takes 16.305 s against 1202.918 s of quick sort. So my question is: are my results as expected, meaning that quick sort is comparable in speed to merge sort for small inputs but, as the size of the input data grows, the fact that its complexity is quadratic will become evident? Here is a sketch of what I did. In the merge sort implementation, the partitioning consists in calling merge sort recursively, i.e. merge_sort(lines, start, (start + end) / 2); merge_sort(lines, 1 + (start + end) / 2, end); Merging of the two sorted sub-array is performed by reading the data from the array lines and writing it to a global temporary array of pointers (this global array is allocate only once). After each merge the pointers are copied back to the original array. So the strings are stored once but I need twice as much memory for the pointers. For quick sort, the partition function chooses the last element of the array to sort as the pivot and scans the previous elements in one loop. After it has produced a partition of the type start ... {elements <= pivot} ... pivotIndex ... {elements > pivot} ... end it calls itself recursively: quick_sort(lines, start, pivotIndex - 1); quick_sort(lines, pivotIndex + 1, end); Note that this quick sort implementation sorts the array in-place and does not require additional memory, therefore it is more memory efficient than the merge sort implementation. So my question is: is there a better way to implement quick sort that is worthwhile trying out? If I improve the quick sort implementation and perform more tests on different data sets (computing the average of the running times on different data sets) can I expect a better performance of quick sort wrt merge sort? EDIT Thank you for your answers. My implementation is in-place and is based on the pseudo-code I have found on wikipedia in Section In-place version: function partition(array, 'left', 'right', 'pivotIndex') where I choose the last element in the range to be sorted as a pivot, i.e. pivotIndex := right. I have checked the code over and over again and it seems correct to me. In order to rule out the case that I am using the wrong implementation I have uploaded the source code on github (in case you would like to take a look at it). Your answers seem to suggest that I am using the wrong test data. I will look into it and try out different test data sets. I will report as soon as I have some results.

  • MvcExtensions - ActionFilter

    - by kazimanzurrashid
    One of the thing that people often complains is dependency injection in Action Filters. Since the standard way of applying action filters is to either decorate the Controller or the Action methods, there is no way you can inject dependencies in the action filter constructors. There are quite a few posts on this subject, which shows the property injection with a custom action invoker, but all of them suffers from the same small bug (you will find the BuildUp is called more than once if the filter implements multiple interface e.g. both IActionFilter and IResultFilter). The MvcExtensions supports both property injection as well as fluent filter configuration api. There are a number of benefits of this fluent filter configuration api over the regular attribute based filter decoration. You can pass your dependencies in the constructor rather than property. Lets say, you want to create an action filter which will update the User Last Activity Date, you can create a filter like the following: public class UpdateUserLastActivityAttribute : FilterAttribute, IResultFilter { public UpdateUserLastActivityAttribute(IUserService userService) { Check.Argument.IsNotNull(userService, "userService"); UserService = userService; } public IUserService UserService { get; private set; } public void OnResultExecuting(ResultExecutingContext filterContext) { // Do nothing, just sleep. } public void OnResultExecuted(ResultExecutedContext filterContext) { Check.Argument.IsNotNull(filterContext, "filterContext"); string userName = filterContext.HttpContext.User.Identity.IsAuthenticated ? filterContext.HttpContext.User.Identity.Name : null; if (!string.IsNullOrEmpty(userName)) { UserService.UpdateLastActivity(userName); } } } As you can see, it is nothing different than a regular filter except that we are passing the dependency in the constructor. Next, we have to configure this filter for which Controller/Action methods will execute: public class ConfigureFilters : ConfigureFiltersBase { protected override void Configure(IFilterRegistry registry) { registry.Register<HomeController, UpdateUserLastActivityAttribute>(); } } You can register more than one filter for the same Controller/Action Methods: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(); You can register the filters for a specific Action method instead of the whole controller: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(c => c.Index()); You can even set various properties of the filter: registry.Register<ControlPanelController, CustomAuthorizeAttribute>( attribute => { attribute.AllowedRole = Role.Administrator; }); The Fluent Filter registration also reduces the number of base controllers in your application. It is very common that we create a base controller and decorate it with action filters and then we create concrete controller(s) so that the base controllers action filters are also executed in the concrete controller. You can do the  same with a single line statement with the fluent filter registration: Registering the Filters for All Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type))); Registering Filters for selected Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type) && (type.Name.StartsWith("Home") || type.Name.StartsWith("Post")))); You can also use the built-in filters in the fluent registration, for example: registry.Register<HomeController, OutputCacheAttribute>(attribute => { attribute.Duration = 60; }); With the fluent filter configuration you can even apply filters to controllers that source code is not available to you (may be the controller is a part of a third part component). That’s it for today, in the next post we will discuss about the Model binding support in MvcExtensions. So stay tuned.

  • PASS Summit 2011 &ndash; Part IV

    - by Tara Kizer
    This is the final blog for my PASS Summit 2011 series.  Well okay, a mini-series, I guess. On the last day of the conference, I attended Keith Elmore’ and Boris Baryshnikov’s (both from Microsoft) “Introducing the Microsoft SQL Server Code Named “Denali” Performance Dashboard Reports, Jeremiah Peschka’s (blog|twitter) “Rewrite your T-SQL for Great Good!”, and Kimberly Tripp’s (blog|twitter) “Isolated Disasters in VLDBs”. Keith and Boris talked about the lifecycle of a session, figuring out the running time and the waiting time.  They pointed out the transient nature of the reports.  You could be drilling into it to uncover a problem, but the session may have ended by the time you’ve drilled all of the way down.  Also, the reports are for troubleshooting live problems and not historical ones.  You can use Management Data Warehouse for historical troubleshooting.  The reports provide similar benefits to the Activity Monitor, however Activity Monitor doesn’t provide context sensitive drill through. One thing I learned in Keith’s and Boris’ session was that the buffer cache hit ratio should really never be below 87% due to the read-ahead mechanism in SQL Server.  When a page is read, it will read the entire extent.  So for every page read, you get 7 more read.  If you need any of those 7 extra pages, well they are already in cache.  I had a lot of fun in Jeremiah’s session about refactoring code plus I learned a lot.  His slides were visually presented in a fun way, which just made for a more upbeat presentation.  Jeremiah says that before you start refactoring, you should look at your system.  Investigate missing or too many indexes, out-of-date statistics, and other areas that could be leading to your code running slow.  He talked about code standards.  He suggested using common abbreviations for aliases instead of one-letter aliases.  I’m a big offender of one-letter aliases, but he makes a good point.  He said that join order does not matter to the optimizer, but it does matter to those who have to read your code.  Now let’s get into refactoring! Eliminate useless things – useless/unneeded joins and columns.  If you don’t need it, get rid of it! Instead of using DISTINCT/JOIN, replace with EXISTS Simplify your conditions; use UNION or better yet UNION ALL instead of OR to avoid a scan and use indexes for each union query Branching logic – instead of IF this, IF that, and on and on…use dynamic SQL (sp_executesql, please!) or use a parameterized query in the application Correlated subqueries – YUCK! Replace with a join Eliminate repeated patterns Last, but certainly not least, was Kimberly’s session.  Kimberly is my favorite speaker.  I attended her two-day pre-conference seminar at PASS Summit 2005 as well as a SQL Immersion Event last December.  Did I mention she’s my favorite speaker?  Okay, enough of that. Kimberly’s session was packed with demos.  I had seen some of it in the SQL Immersion Event, but it was very nice to get a refresher on these, especially since I’ve got a VLDB with some growing pains.  One key takeaway from her session is the idea to use a log shipping solution with a load delay, such as 6, 8, or 24 hours behind the primary.  In the case of say an accidentally dropped table in a VLDB, we could retrieve it from the secondary database rather than waiting an eternity for a restore to complete.  Kimberly let us know that in SQL Server 2012 (it finally has a name!), online rebuilds are supported even if there are LOB columns in your table.  This will simplify custom code that intelligently figures out if an online rebuild is possible. There was actually one last time slot for sessions that day, but I had an airplane to catch and my kids to see!

    When an HPCM application is first created, it is likely that you will want to carry out some optimisation on the HPCM application’s Essbase outline in order to improve calculation execution times. There are several things that you may wish to consider. Because at least one dense dimension for an application is required to deploy from HPCM to Essbase, “Measures” and “AllocationType”, as the only required dimensions in an HPCM application, are created dense by default. However, for optimisation reasons, you may wish to consider changing this default dense/sparse configuration. In general, calculation scripts in HPCM execute best when they are targeting destinations with one or more dense dimensions. Therefore, consider your largest target stage i.e. the stage with the most assignment destinations and choose that as a dense dimension. When optimising an outline in this way, it is not possible to have a dense dimension in every target stage and so testing with the dense/sparse settings in every stage is the key to finding the best configuration for each individual application. It is not possible to change the dense/sparse setting of individual cloned dimensions from EPMA. When a dimension that is to be repeated in multiple stages, and therefore cloned, is defined in EPMA, every instance of that dimension has the same storage setting. However, such manual changes may not be preserved in all cases. Please see below for full explanation. However, once the application has been deployed from EPMA to HPCM and from HPCM to Essbase, it is possible to make the dense/sparse changes to a cloned dimension directly in Essbase. This can be done by editing the properties of the outline in Essbase Administration Services (EAS) and manually changing the dense/sparse settings of individual dimensions. There are two methods of deployment from HPCM to Essbase from 11.1.2.1. There is a “replace” deploy method and an “update” deploy method: “Replace” will delete the Essbase application and replace it. If this method is chosen, then any changes made directly on the Essbase outline will be lost. If you use the update deploy method (with or without archiving and reloading data), then the Essbase outline, including any manual changes you have made (i.e. changes to dense/sparse settings of the cloned dimensions), will be preserved. Notes If you are using the calculation optimisation technique mentioned in a previous blog to calculate multiple POVs (https://blogs.oracle.com/pa/entry/hpcm_11_1_2_optimising) and you are calculating all members of that POV dimension (e.g. all months in the Period dimension) then you could consider making that dimension dense. Always review Block sizes after all changes! The maximum block size recommended in the Essbase Database Administrator’s Guide is 100k for 32 bit Essbase and 200k for 64 bit Essbase. However, calculations may perform better with a larger than recommended block size provided that sufficient memory is available on the Essbase server. Test different configurations to determine the most optimal solution for your HPCM application. Please note that this blog article covers HPCM outline optimisation only. Additional performance tuning can be achieved by methodically testing database settings i.e data cache, index cache and/or commit block settings. For more information on Essbase tuning best practices, please review these items in the Essbase Database Administrators Guide. For additional information on the commit block setting, please see the previous PA blog article https://blogs.oracle.com/pa/entry/essbase_11_1_2_commit
