Collect Java dumps and core files
New feature: The JVM is capable of producing Java dump and core files to aid in troubleshooting.
- Use heap dump and system dump files to diagnose memory-related problems, such as memory leaks
- Use Java core files to diagnose problems where the CPU is persistently 100% busy, when threads are hanging, or where threads are in a deadlock.

Troubleshooting | Java dumps and cores | server(s) | [System Dump | Java Core | Heap Dump]
The system dump or heap dump or Java core is created and stored in the profile root directory of the server from which you requested the dump or core.
The process of generating dump and core files can have a noticeable performance impact on the system that can last for many seconds or minutes. If necessary, use your test and development environments to better understand the impact of generating dump and core files.
Generating a heap dump or a system dump is not supported for a non-IBM JVM. If attempted, the following message is displayed in the administrative console:
The Heap dump request to the server <server_namegt; failed because of the following reason: Could not take single dump as Sun Microsystems Inc. is not supported.
...or...
The System dump request to the server <server_namegt; failed because of the following reason: Could not take single dump as Sun Microsystems Inc. is not supported.
For HP-UX...
The Heap dump request to the server <server_namegt; failed because of the following reason: Could not take single dump as HP-UX is not supported.
...or...
The System dump request to the server <server_namegt; failed because of the following reason: Could not take single dump as HP-UX is not supported.
