Memory allocation configuration

[Former Member]

Hi Experts,

How to configure the memory allocation usage for each service to increase the performance of the portal. The performance of portal is very slow and we are working on NW 2004s SP10 portal.

Any help can be rewarded.

Dear

Memory

The total amount of memory allocated by all Java processes and other processes relevant to the portal (e.g. database processes if running on the same host) has to fit into main memory.

In particular, the sum of the heap size (Xmx, Xms) and the maximum PermSize for all JAVA processes must be configured to fit completely into main memory (RAM) since the effect of paging will be much more intensive than in any other program. When calculating the sizes, also consider memory needed by all other active processes and by the operating system itself.

Hi Shailesh,

I agree with you, is there any documentation to calculate these sizes based on the available RAM size.

Sudhir,

Have you searched on SAPNet and followed the recommendations in note 723909?

Hi Paul,

Yes I have seen the note, apart from that is there any document / Help file delivered by SAP for Fine tuning of performance on EP 7.0?

No there doesn't appear to be one for EP7, but EP6 (on 6.40) and EP7 are very similar so the recommendations have not changed.
