Detailed Problem Description
Message Raised to SAP
We recently migrated our database from BW 7.3 on oracle to BW 7.4 on HANA sp12. This was done by SAP deployment /SDC team. After the go live, we encountered few short dumps happening randomly.
Then SAP did the following two steps :
- Note 2387692 - P20; RSSM_GET_TIME: Longer threshold for determination of long TS was implemented
- When the exception again occurred, SAP had requested to check whether the time is synchronized between ABAP, DB and Kernel .
If all are in sync, then we were advised to create a ticket for further investigation and hence doing the same.
So far we are noticing this short dump to happen during 4.30 to 6 am ET and not during any other time.
Few time we have noticed this random behavior:
1. Process chain Schedule failure:
Process chain(ZPC_SD_ORDER) is scheduled to start at 05:30:00 AM EST in BW production(BPP),
But process chain didn’t get started, however the background job that triggers the Process chain got failed & a short dump “RAISE_EXCEPTION” is generated
This issue is seen 2 days continuously.
2. Infopackage schedule failure :
For a full load infopackage, the background job got failed & a short dump “RAISE_EXCPETION” is generated.
3. Manage tab of DSO/Infocube in RSA1 Workbench:
When manage tab of Infocube/DSO is navigated, this results in shortdump “RAISE_EXCEPTION”.
This issue is seen 6 to 7 times after the upgrade.
RSA1 à Search for one of the Info cubes à select manage tab
Solution Analysis and Recommendations
Issues is redirected to SAP Development team & they are currently monitoring BW systems
