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.

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).
Best regards, Michael
