Dynamic saveabend file creation

NOTE:

Dynamic saveabend file creation works only with Java processes. It will not work with javahelper processes.

Dynamic saveabend file creation helps to create a saveabend file of a running Java process without aborting (abending) the Java process, and by issuing a signal to the process. This allows the Java process to continue execution even after the abend file is created. The time taken to create the abend file, that is the application pause time is low (measurable in milliseconds).

The saveabend file enables you to analyze any observed Java runtime problems, such as observed high memory consumption, and low responsiveness without impacting the running Java process.

To create a saveabend file in the working directory of the process, perform the following steps:

  1. Export DUMP_CORE=1.

  2. Start the Java application.

  3. Press Ctrl+break while the process is running.
