Thank you Yashwanth,
I will open 2 customer messages, each for one problematic productive system.
I wonder one thing:
At QAS system I set the Parameter to 10 GB (at 64 GB Cache Size). As expected the system startup speeds up to 5 minutes. Before the database patch from 7.9.8.7 to 7.9.8.11 the start needs between 15 and 20 minutes.
At PRD system I did not set the parameter, because I had not found properly information which value may be recommended. I was afraid to waste cache size. The system startup speeds up to 5 minutes, too.
What I am missing in documentaion of this parameter:
Where is the cache located? e.g. Cache-Size, Catalog-Cache, seperated
Which value is recommended? e.g. 10% Cache Size, 100 MB, 50% Catalog size, 1 % database size
Are there any risks? e.g. wasting memory, database consitency, performance issues
If this parameter should not be used except of recommendation by SAP support, I would like to have this told in documentation.
Best Regards
Andreas
