Hi guys,
I have backend system on ERP 6.0 EHP6 with Central instance, one dialog instance and the database instance. Then I have a Portal with SSO configured with the backend. Number of users is considerably increasing and some heavy report-like transactions (Z reports) are causing some performance issues in the backend system. I have a few questions for clarification:
1) When a user makes a request in the Portal, the request is eventually fulfilled from which instance - the CI or the DI? In SM04, I can see plug-in users ...
2) In SM50, I see several RFC requests. Can this have an impact on performance of the CI ? What about the table TFRCQOUT? I can see it growing gradually. Is there some maintenance we need to do this table? I've seen note 375566 referring to this table.
3) I have some 500 users. My CI and DI have both 22 dialog work processes. At times, I can see in SM50 the number of free dialog processes reaches 0 (i.e all dialog WPs runnning). Is this sufficient?
I am planning to create a dialog instance to cater for the increasing load.
4) On my portal, I have 3 server nodes with 3GB heap size for each. Normally, I do not see Full GCs occuring as of now. Is there a way to know (t-code, report, etc) that the 3 server nodes are sufficient to handle the current load?
regards,
Suraj
