Data warehouse jobs fail and event ID 33502 is logged

This article helps you fix a problem in which data Warehouse jobs fail in Microsoft System Center 2012 Service Manager and event ID 33502 is logged.

Original product version:   Microsoft System Center 2012 Service Manager, System Center 2012 R2 Service Manager
Original KB number:   3137611

Symptom

Data warehouse jobs fail in Microsoft System Center 2012 Service Manager. When this problem occurs, the following event is logged in the Operations Manager event log on the data warehouse server:

Log Name: Operations Manager
Source: Data Warehouse
Event ID: 33502
Level: Error
Description:
ETL Module Execution failed:
ETL process type: Transform
Batch ID: <Batch ID>
Module name: TransformEntityRelatesToEntityFact
Message: ErrorNumber="50000" Message="Unable to acquire applock - another instance of the module must already be running." Severity="18" State="1" ProcedureName="InitializeTransform" LineNumber="52" Task="(null)"

Also, when you run certain data Warehouse-related cmdlets, you frequently see a time-out error recorded for the TransformEntityRelatesToEntityFact module that resembles the following:

Get-SCDWJobModule -JobName transform.common
...
1952 TransformEntityRelatesToEntityFact Failed
...

Cause

This problem can occur if the volume of transform data exceeds the amount that can be processed by the transform modules within the time-out period. It typically occurs after data warehouse jobs were disabled for some time because the volume of data to be transformed can become quickly backlogged. By default, data warehouse transform jobs have a hardcoded 60-minute time-out.

Resolution 1

If you are currently in a failed state, use Resolution 1 to process the backlog and return the operation to a functioning status. The other two methods are ways to prevent the issue from reoccurring. To do it, wait for the status of all data warehouse jobs to be displayed as Not Started or Failed, and then follow these steps:

1. On the data warehouse server, stop the HealthService service at an elevated command prompt. To do it, run the following command:

   Net Stop HealthService
   

   Note

   Depending on your version of Service Manager, this service name might be displayed as either Microsoft Monitoring agent or System Center Management.

2. Update the following SQL query to reflect the ModuleName value of the module in the Transform.Common job that's failing. This example uses TransformEntityRelatesToEntityFact.

   Note

   The simplest way to see the ModuleName value for the module that's failing is to open the Service Manager console, select Data Warehouse, select Data Warehouse again, select Data Warehouse jobs, and then select Transform.Common. In the bottom-center pane, you can see a list of modules and the current status. After you make the changes, run the query.

   Use DWStagingAndConfig  
   declare  
   @mybatchid INT,  
   @mysourceid INT,  
   @outXML XML,  
   @myProcessCategoryName NVARCHAR(100),  
   @myProcessName NVARCHAR(100),  
   @myModuleName NVARCHAR(100),  
   @sqlString NVARCHAR(150),  
   @paramDef NVARCHAR(100)  
   set @myProcessCategoryName = N'Transform'  
   set @myProcessName = N'Transform.Common'  
   set @myModuleName = N'TransformEntityRelatesToEntityFact'  
   USE DWStagingAndConfig  
   create table #MyTempTable (  
   ProcessCategoryName NVARCHAR(150),  
   ProcessName NVARCHAR(150),  
   BatchId INT,  
   BatchStatus NVARCHAR(150),  
   WorkItemStatus NVARCHAR(150),  
   WorkItems INT  
   )  
   insert #MyTempTable  
   exec Infra.GetBatchDetails @ProcessCategoryName=@myProcessCategoryName, @ProcessName=@myProcessName  
   select @mybatchid = BatchId from #MyTempTable  
   select @mysourceid = sourceid from etl.source where SourceName='SCDW'  
   create table #MyTempTable2 (  
   myWaterMark XML  
   )  
   insert #MyTempTable2  
   exec etl.GetWaterMark @BatchId=@mybatchid, @ModuleName=@myModuleName, @ProcessName=@myProcessCategoryName, @SourceId=@mysourceid  
   select @outXML = myWaterMark from #MyTempTable2  
   create table #MyTempTable3 (  
   myWaterMark XML,  
   BatchId INT,  
   UpdatedRowCount INT,  
   InsertedRowCount INT  
   )  
   USE DWRepository  
   set @paramDef = N'@ioutXML XML'  
   set @sqlString = 'insert #MyTempTable3 exec ' + @myModuleName + 'Proc @WaterMark=@ioutXML'  
   exec sp_executesql @sqlString, @paramDef, @ioutXML=@outXML  
   select @mybatchid = BatchId, @outXML = myWaterMark from #MyTempTable3  
   USE DWStagingAndConfig  
   exec etl.SetWaterMark @BatchId=@mybatchid, @ModuleName=@myModuleName, @ProcessName=@myProcessCategoryName, @SourceId=@mysourceid, @WaterMark=@outXML  
   update infra.workitem set statusid = 6 where batchid = @mybatchid
   update infra.batch set statusid = 6 where batchid = @mybatchid
   exec infra.CreateBatch N'Transform.Common'
   drop table #MyTempTable  
   drop table #MyTempTable2  
   drop table #MyTempTable3
   

3. If the script above displays the following message:

   "Unable to acquire applock - another instance of the module must already be running"

   execute the following query from SQL Server Management Studio then re-execute the SQL query in step 2:

   insert #MyTempTable
   exec Infra.GetBatchDetails @ProcessCategoryName='Transform', @ProcessName='Transform.Common'
   GO
   Update infra.workitem set statusid = 6 where batchid IN (SELECT myBatchID FROM #MyTempTable)
   GO
   Update infra.batch set statusid = 6 where processid = (SELECT ProcessId from infra.process where processname = 'Transform.Common')
   GO
   EXEC infra.CreateBatch 'Transform.Common'
   DROP TABLE #MyTempTable
   

4. Restart the HealthService service at an elevated command prompt. To do it, run the following command:

   Net Start HealthService
   

Resolution 2

If you're using Forefront Identify Manager (FIM), this problem may recur because of the flow of data that reaches Service Manager. To spread the workload for this data, change the FIM_ScheduleReportingIncrementalSynchronizationJob schedule from the default value of every 8 hours to every 2 hours. To do it, follow these steps:

1. In SQL Server Management Studio, connect to the FIM database, expand SQL Server Agent, and then select Jobs.
2. Right-click FIM_ScheduleReportingIncrementalSynchronizationJob, select Properties, and then select Schedules.
3. Change the Occurs every value for FIM_UpdateReportingIncrementalSynchronizationJobSchedule_1 to 2 hours.

Resolution 3

For a more long-term solution, upgrade to Microsoft System Center 2012 R2 Service Manager Update Rollup 4 (UR4) or a later version. Beginning in Update Rollup 4, Service Manager has an adjustable time-out setting. Also, the default data warehouse transform job time-out changes from 60 minutes to 180 minutes. If three hours aren't long enough for the Transform.Common module to finish, you can increase the value by changing the following registry value:

HKLM\SOFTWARE\Microsoft\System Center\2010\Common\DAL

• SqlCommandTimeout = (DWord 32-bit in second)
