Background documentationThe Startup Framework for AS Java Locate this document in the navigation structure


You can start, stop, and monitor the AS Java using the Startup Framework for AS Java. This framework provides centralized management of the Java server processes and monitors their life cycle. In case of cluster node failure, the framework automatically restarts the corresponding process.

The Startup Framework provides the following services:

  • It serves as a single point of administration (starting, restarting, stopping, and monitoring) for the AS Java processes.

  • In case of a process failure, it restarts the corresponding process.

  • It displays the trace files, the system environment, and the SAP system environment.

  • It provides options for thread dump monitoring.

    This option is critical for the analysis of problem situations (for example, the AS Java is hanging, 100% CPU load).

  • It provides options for viewing the Java VM output (useful in case of a Java server crash).
