What is a PHD file?

Data file created in the Portable Heap Dump format, which is used to create Java heap dump files using IBM's version of the Java Virtual Machine (JVM); may contains a record of all Java heap objects; used for debugging application errors such as memory leaks.

More Information

Portable heap dumps can be generated by setting the following environment variable parameters: IBM_HEAP_DUMP=true and IBM_HEAPDUMP=true. PHD files may be saved in a text or a binary format. However, the binary format is much smaller in file size. To specify the text format, set the IBM_JAVA_HEAPDUMP_TEXT=true environment variable.

NOTE: Portable heap dumps are typically generated by killing a running Java application. Therefore, to create a PHD file, start your Java program with the required environment variables set and then kill it.
