Manual update of SDM 'hanging'

[former_member235924]

Hello,

after having an issue with JSPM I am trying to update the SDM manually. The job is running (JVM-bin/SDM.jar), uses a lot of CPU, but doesn't seem to do anything. It was running for nearly 20 hours, then I cancelled it and restarted the update.csh. Still looks the same. Has anyone seen this before?

I have had the same JSPM error on a Windows system before and SAP recommended to update the SDM manually which worked without problems.

To Correct my issue, in the following command I changed the Xmx384M to 512M

/QIBM/ProdData/Java400/jdk14/bin/java -Xmx384M -jar

/usr/sap/<SID>/<CInn>/SDM/program/bin/SDM.jar jstartup

mode=standalone sdmhome=/usr/sap/<SID>/<CInn>/SDM/program

logfile=/<chooseName>.log

and in the update.csh file in the SDM upgrade directory I changed all the -Xmx64M lines to -Xmx256M.

After these changes I was able to upgrade to SDM's in two separate SAP instances manually and error free.

Thank you for all the assistance,

Hello Doug,

the changes in the update.csh did it. I was able to update the SDM manually without any issues.

Thanks a lot,

Christoph, Teddy,

Thanks for your responses. I had already checked these on Friday and increased the one in sdm_jstartup.properties which helped.

I am still having issues with the SDM, but as I was able to deploy manually and my JSPM seems to work again without issues, I will stop investigating at this point, hoping that the next SPS fixes all the problems.

Thanks,

Hello Ingrid,

I have run into the very same problem with the update job running and running and not doing a thing and haven't found an answer yet. If I do I will post it here for you as well.

Hi Ingrid, Doug,

in general that SDM update should work.

Sounds like an issue for an SAP support ticket. I'd like to see a DMPJVM of the looping process.

Best regards

Hi Christoph,

I had opened a ticket with SAP regarding a BI problem where I was asked to deploy to BI SCA patch files. There I started having problems with SDMgui and then JSPM.

I was meanwhile able to deploy the two SCAs directly (SDM without SDMgui: set the SDM to standalone mode and execute the following commands:

/SDM/program/sdm.sh deploy file=*.SCA updateversions=all

).

The ticket is still in BC-JAS-DPL, but the thread dumps attached to the ticket are for the hanging SDM GUI, not the manual upgrade of SDM.

Hi Ingrid,

when you post the ticket number I could have a look...

Best regards

Hi Christoph,

thanks for your interest. The ticket is 356846.

SAP asked me to turn on the SDM trace. Doing this I cannot even connect with the SDMgui, but I see an Outofmemory error in SDM. So I am thinking this might have been the problem all along and checking it out.

I will update the post if I find anything.

Thanks,

Ingrid

Hello Ingrid.

With the OutOfMemory error I remember finding a note stating that the value 'set sdm_heap_size=64' should be changed to 'set sdm_heap_size=256' in the file Y:\usr\sap\<sid>\DVEBMGS<no>\SDM\program\SDM_jdk.bat.

Hi Ingrid,

I think Teddy's hint goes into the right direction.

For the SDM GUI, check the settings in /usr/sap/<SID>/<Instance>/SDM/program/sdm_jdk.bat

The value for sdm_heap_size should be reasonable, e.g. 256 or 512 or such. No value should be set for sdm_java_params.

Then, for the SDM server you need to check /usr/sap/<SID>/<Instance>/SDM/program/config/sdm_jstartup.properties

The value sdm.MaxHeapSize should not be too small. I'd recommend a value of at least 1GB. And in sdm.JavaParameters you can specifiy the initial heapsize which should not be higher than maxheap/4.

If you're using the SDM via starting in the shell by StartServer.sh, not running in the instance subsystem, then you need to implement the SDM server settings in /usr/sap/<SID>/<Instance>/SDM/program/sdm_jdk.sh

Hope that helps,

Christoph
