Recommended Buffer Parameter values for Netweaver BW

[Former Member]

Dear Experts,

I received below alert on SAP NetWeaver BW system.

SpaceUsed: 99 % > 98 % (15 Min.) SAP buffer:buffer storage usage exceeds threshold.

I took SAP restart and now the alert is disappeared. However, it seems that the memory parameter values has been set to low.

Can someone please tell me where can I find the recommended memory parameter settings on BW NetWeaver 7.X system?

Thanks in advance...

Hello

It is not possible to answer your question... you did note provide enough information: OS, total memory, Is DB on the same host...

Further more buffer sizing depends on the usage of your system.. have a look in ST02.
