Performance of the J2EE server for BI 70

36 Views

Hi

We currently are running BI 70 on as 20GB(memory in *BASE), 1.5 CPU (power 6) system.

We have close to 100 users on the system and primarliy use the excel based Bex analyzer for reporting,

We want to start using the BI-Java stack for web based reporting, but right now its kind of a little slow, esp going in their the first time after the system restarts..( which is kind of understable..)..and even after then...

We have already implemneted these notes for performance:

Note 990892 - iSeries Java properties in SAP system environment

Note 717376 - iSeries VM Settings for SAP WebAS Java (IBM Classic JVM)

and are noticing little improvement...but still not as good as we would like it to be...

The question we have in mind is if:

we should start thinking about running the Java server in a separate memory pool? Right now

the "SERVER0" job is running in *BASE...same as where our ABAP stack is running...We only have two memory pools on the system(machine and *Base)

Which configuration is better in terms of performance, for both ABAP and JAVA? We do not want the ABAP performance to go down...( faulting rates right now is less than 100/s...but goes up when we run BI-JAVA)

Running both ABAP and JAVA in the same (one big HUGE) memory pool

OR

Spliiiting up the *BASE and allocating maybe like 5- 5.5 GB to another pool and run the J2EE in that seperate memory pool, as mentioned in one of the SAP notes??

Thanks for all your suggestions...
