Opens a system dump for analysis by the System Dump Debugger
    (kept debugger only).

    Format

      ANALYZE/CRASH_DUMP

1  –  Description

    For OpenVMS Integrity servers and Alpha systems, invokes the
    System Dump Debugger (SDD) to analyze a system dump.

    SDD is similar in concept to the System Code Debugger (SCD).
    While SCD allows connection to a running system, with control of
    the system's execution and the examination and modification of
    variables, SDD allows analysis of memory as recorded in a system
    dump.

    Use of SDD usually involves two systems, although all of the
    required environment can be set up on a single system. The
    description that follows assumes that two systems are being used:

    o  The build system, where the image that causes the system crash
       has been built

    o  The test system, where the image is executed and the system
       crash occurs

    In common with SCD, the OpenVMS debugger user interface allows
    you to specify variable names, routine names, and so on,
    precisely as they appear in your source code. Also, SDD can
    display the source code where the software was executing at the
    time of the system crash.

    SDD recognizes the syntax, data typing, operators, expressions,
    scoping rules, and other constructs of a given language. If your
    code or driver is written in more than one language, you can
    change the debugging context from one language to another during
    a debugging session.

    To use SDD you must do the following:

    o  Build the system image or device driver that is causing the
       system crash.

    o  Boot a system, including the system image or device driver,
       and perform the necessary steps to cause the system crash.

    o  Reboot the system and save the dump file.

    o  Invoke SDD, which is integrated with the OpenVMS debugger.

    For more information about using the SDD, including a sample SDD
    session, see the VSI OpenVMS System Analysis Tools Manual.
