To manually generate
heapdumps, set a JVM parameter. Then send the JVM process an interrupt (signal
3), a javacore and a heapdump will be generated.
In the Administrative Console:
Servers > Application
Servers > serverName:
In the Server Infrastructure
section open Java and Process Management, then select Process Definition:
In the Additional Properties
select Java™ Virtual Machine:
Add the following string to
the Generic JVM arguments field:
-Xdump:heap:events=user
Press OK, and save the
configuration.
Note: The Application Server
will need to be recycled for the setting to take effect.
To generate the heapdump,
send the Application Server an interrupt. Use the "kill" command:
kill -3 <java process
ID>
To get process id
ps -aux | grep java (Look for server1)
