Huge Perfromance System in Production

Former Member

Hi to All,

Ours is a Complete SAP application with webdynpro for Java SAP R/3

At our Pre-Production Server Validating a Order takes in seconds

but where as in Production System its taking 10 to 20 mins to Validate an Order

Back End is ABAP and front end is developed in webdynpro for Java

not able to trace where the problem is

what are the check points to be made in SAP Netweaver administration side to make sure the Appserver is working with optimised performance

Is there anything in SAP Netweaver Administration side to test the performance or any other issues related to it

so that we can check this.

Thanks and Regards

Chandra

Hi,

for deep-dive analysis of java part use SAP JVM Profiler

http://www.sdn.sap.com/irj/scn/downloads?rid=/library/uuid/a0a67d7d-36e9-2a10-3a99-94fc8caaea0e

For deep-level analysis of ABAP server use ST05 and SE30.

Best Regards,

Sylvia

Are you having any performance problems in the ABAP end also...?

if not then i think it should be a network problem.

Hi

Thanks for your reply,

we have optimised the performance from the ABAP, but we are not sure how to check the performance from the Java Level

and also

Not sure if we missed something in the netweaver administrator setting or configurations

Thanks and Regards

Hi ,

since you are using the java application for just the front end, so you cannot find anything on the java system, as all the processing is done in the backend system.

As your ABAP system is optimised, i suggest to take network slowness also into consideration.

Hi,

We have raised a request to SAP to inspect the problem, Now the SAP is sending some Neteweaver Admin professional to have look at the system

Just three genereal hints for java performance issues:

- Check if garbage collection is an issue. A lot of J2EE performance issues i have seen so far, were due to garbage collection. Signs are temporary freezes of http requests, the more users the worse. Check the logs of your server0 process (might be std_server0) for activity. Also check your heap memory usage.

- If you have a lot of users, it could help adding more java server processes to your existing instance. This can help for garbage collection issues as well.

- Check if your J2EE settings are correct and you are on a current JDK patch level. Depending on your platform there can be significant performance improvements (and new settings as well).
