Hi,
We're running LiveCache 7.9.08 on Windows 2008 R2.
Our current settings are:
PhysMem 32GB
CacheMemorySize 1678000
OmsMaxHeapSize 16098400
Data Cache Usage 89%
OMS Data 87%
HitRate is 99.9% so that is good.
Due to filling level believe we need to increase Cache sizes. I’ve been led to believe total cache should be no more than
50% of physical memory and OMS should be about 75% of total cache. Are these numbers in line with current SAP standards?
If not, what are SAP recommendations?
Thanks,
Heidi
Hello Heidi,
What is the version of your system & the version of the liveCache including the build?
Did you update to the latest release using SAP Note 1955604?
Was your system upgraded from Version 7.0 or 7.01?
What is the perminent data area usage?
Did you check/delete all permanent data in liveCache?
In general, please review the SAP note:
1173395 - FAQ: SAP MaxDB and liveCache configuration
It has the reference to information about the Quick Sizer is available on SAP Service Marketplace: http://service.sap.com/quicksizing.

We don't know what you are refering to? Is there a cleanup job we should be running?
Hello,
"Did you check/delete all permanent data in liveCache?

I planned to ask you if you checked with the application team on the deletion of the liveCache data which they don't need any more, created just for tests.
Check if you have f Old Saved Trans Sim, copies of planning versions.
Delete the superfluous TS objects.

Did you already try the Quick Sizer is available on SAP Service Marketplace: http://service.sap.com/quicksizing ?
It's dependent on the OS resources of the liveCache server.
You have currently:
PhysMem 32GB
CacheMemorySize 1678000 < in pages, *8KB >
OmsMaxHeapSize 16098400 < in KB >
Good to check the available physical memory on the server for the liveCache instance, if you plan to increase CacheMemorySize value.

Similar question with Heidi - is there any sizing tool to help us understand if our current LiveCache reach the SAP recommendation?
Thanks a lot.
