DeskTop HeapSize Changes for QlikView Task

[Truist_np]

Hello Team,

In our QlikView Environment, there are many task and one of task is failing . The error I get is as below.

Task execution failed with errors to follow. ---> QDSMain.Exceptions.ReloadFailedException: Reload failed ---> QDSMain.Exceptions.LogBucketErrorException: The sourcedocument failed to reload.. Exception=System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from 

One of Window Desktop Heap size:

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,4096 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

I got recommendation from Qlik Support to Change the desk top heap size  to 6144 or 8192.

I am going to implement this changes in Dev, Test Server first as it contains Risk. Can anyone guide what precaution and back up should I take before implementing this changes.

Thanks,

Niharika

Niharika,

No backup necessary in  QV environment as this is a Windows Registry change. The only backup maybe I would suggest is just have a snapshot of your Windows Server environment taken prior to making the Registry change. That way if something errors out you can revert the entire server back to before the change was made.
