Portal KM BI Integration - Serious Performance Issue

18 Views

Hi guys,

we've implemented BI KM Integration in our portal environment.

This means that we can now navigate to :

/irj/servlet/prt/portal/prtroot/com.sap.km.cm.navigation/bw_metadata/activeVersion/Query/

Well, from a functional perspective this BI-KM integration is fine. The problem is performance-wise.

Our system is a 64-bit AIX DB2 and our JVM has been configured with the following settings:

-2560 max heap size

-Xmx2560m

-Xms2560m

-Xmn1000m

When the portal restarts, as KM comes up first, performance is fine but after half an hour it deteriorates until it comes to a crawl and a restart is needed. There are only a couple of guys on the system doing little activity and the back-end performs quite okay.

I think the problem is more JVM related (GC cycles) and from the NetWeaver Administrator I haven't been able to grab much info (also it's very very slow)....

Any ideas?
