Sun Java Application Server 9.1 – OutOfMemoryError

We have installed SJSAS 9.1 on our production server (SPARC). It has 8 GB memory.

In the first day, we were getting whole lot of sever warning:

PWC1406: Servlet.service() for servlet TechnicalLibraryServlet threw exception java.lang.OutOfMemoryError: Java heap space

So, we have increased the heap size from default 192 to 512

Application Server –> JVM Settings –> JVM Options

How to check the current heap size?
Application Server – Monitor –> Runtime
How to Monitor SJSAS 9.1?
Setup a Monitor: Configuration –> Monitor

How to View?
Application Server –> Monitor (You may the Display Chart button to see nice looking graph)
How to check Open and Close Connections?
Application –> Monitor –> Resources

Apparently by increasing heap size did not help much. So we decided to install SJSAS 9.1 Update 1

Results: Wonderful but what an experience. I wish Sun would have fixed this out of memory issue before distribute SJSAS 9.1. I guess that’s why they came up with UR 1, which makes sense.
