Upon investigation of a WebSphere Application Server performance issue, you may find that the poor performance correlates with long classloader unload times. To check if this is indeed a problem, enable verbose GC and note the times of poor performance. Then correlate the times of poor performance to the time stamps in the verbose GC data:   Example of long class unload time as seen in the verbose GC output (default log is the native_stderr.log in WebSphere): ... <classunloading classloaders="3058" classes="6490"...

  If you want to integrate an externally long running service in an IBM Business Process Manager process application, the best practice is to use asynchronous calls. The reason for this practice is that long running synchronous call from IBM Business Process Manager to the outside service can lead to many potential problems. IBM Business Process Manager will keep a thread alive for the synchronize calls during the execution. It will hold many resources, such as table lock in the BPMDB, java heap. It can block the other threads from... [More]
