Thanks a lot. Will go through them.
You can connect to the admin server with wlst and fire dumpStack() to get the dump. You can also redirect to a file for later reference.
This options works only when we restart the server and again when the server goes out of memory we can get the heapdump as per the arguments which you mentioned.
But how to collect a heapdump of a server which ran out of memory and which did not have those arguments of "-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath="
Hi Could you elaborate more on this. I tried it but it seems it dumps stack traces and not heap dump.
