  • dumping a JVM heap using gdb

    now this is a neat trick — having been stuck having to flip to spares and do other antics while a long-running heap dump took place, this is a winner.

    Dumping a JVM’s heap is an extremely useful tool for debugging problems with a J2EE application. Unfortunately, when a JVM explodes, using the standard jmap tool can take an inordinate amount of time to execute for lots of different reasons. This leads to extended downtime when a heap dump is attempted and even then, jmap regularly fails. This blog post is intended to outline an alternate method using [gdb] to achieve a heap dump that only requires mere seconds of additional downtime allowing the slow jmap process to happen once the application is back in service.
