IS is slow


If my Integration server is slow in responding, what and all I need to check?

and If restart is necessary how to take thread and heap dump?


Generate JVM Thread Dump from Server > Statistics > System Threads

Monitor the server.log or put your server in safe mode and do a diagnostic. Refer admin guide for more information.

Check your JVM memory in or server.bat


Define what kind of GC you want to be performend on the jvm.
I can’t help you with what kind that you need to use, this depends on the type of processes it handels.
But online you can find tons of info about GC.
