Summary :
This SAP Note provides guidelines for creating a heap dump in HPROF binary format for Java stack memory analysis, specifically for JVM versions that support this feature, such as SUN JVMs 1.4.2_12+ and HP-UX VM 1.4.2_11+. Users can configure the JVM to generate a heap dump automatically upon encountering an OutOfMemoryError, or manually by triggering a SIGQUIT (UNIX) or CTRL_BREAK (Windows). The note details the specific Java options to be added, the output file name format, and storage directory paths. It also advises managing disk space due to the potential large size of heap dump files and offers configuration settings for custom dump file paths.
