Hi Vadi,

another way to findout which application is starting is to look at the MMC, e.g.

http://javaserverhost:50013 -> AS Java -> Threads

In the list of threads one can see the task/method which is currently executed and the accumulated CPU and elapsed time in this method from the time it started.

Best Regards,

There may be couple of reasons for slow server )

Is the CPU on 65% when there are no active users in the system? If so, it may be a background process doing some activity. You can catch it with a thread dump – take a few thread dumps with few seconds intervals and look for active threads. When you find the running threads you will also see the java stack trace that will give you some indication on who is doing what.

To take thread dumps – find the server node in the SAPMMC, right click and choose “Dump Stack Trace” (5 times with 10 seconds interval should be fine). You will find the dumps in C:\usr\sap\<SID>\JCxx\work, the file name is dev_server<nodeID>. You can easily spot the active threads, usually their stack trace will be longer than the rest.

Good luck,

Yoni
