Enable Heap Dump on Out of Memory
Select True from the drop-down list if you
want to generate a heapdump when the
server JVM encounters an out of memory
error.
Heapdumps are useful for troubleshooting
memory-related issues since they contain all
the live objects used by the Java application.
With this information, the objects that are
using large amounts of memory can be
identified. The contents of a heapdump can
also help a user understand why objects
cannot be freed by the Garbage Collector.
By default, the dump file is generated from
where the JVM was started (the
install_dir/bin directory).
If you select False from the drop-down list,
heapdumps are not generated when the
server JVM encounters an out of memory
error.
