/SSLOG=(STATE={ON | OFF | UNLOAD} [,COUNT=n] [,FLAGS=[NO]ARG])

    Valid on Alpha and Integrity server systems only.

    Requires CMEXEC, CMKRNL, or SETPRV privilege to log argument
    values. The SYSGEN parameter SYSSER_LOGGING must be enabled or
    the command will fail.

    Enables or disables system service logging, using a log file
    (named SSLOG.DAT by default) to log data.

    Keywords are as follows:

    Keyword        Explanation

    COUNT=n        Specifies how many P2-space buffers to log.
                   (Default: 2)

    FLAGS=[NO]ARG  Specifies whether service argument values are to
                   be logged. (Default: ARG) ARG requires CMEXEC,
                   CMKRNL, or SETPRV privilege.

    STATE=state    Turns system service logging on or off. Possible
                   states are:
                   ON       Enables system service logging.
                   OFF      Disables (turns off) system service
                            logging; logging can still be reenabled.
                   UNLOAD   Stops logging and closes the log file,
                            which is named SSLOG.DAT by default.

    When enabling SSLOG for a process, you can specify the number of
    buffers to be used for logging. Buffers are allocated in P2 space
    and are charged against the process's paging file quota. Each
    buffer is 65,024(10) bytes or FE00(16) bytes. The buffer space
    remains allocated and the quota is charged until the process is
    deleted.

    Between the time when SSLOG is first enabled and when the log
    file is closed, logging can be stopped and resumed.

    Before you delete the process, you should stop all logging and
    close the log file. The log file does not close automatically.

    To analyze the log file, use the DCL command ANALYZE/SSLOG, which
    is described in online help and in the System Service Logging
    chapter of the VSI OpenVMS System Analysis Tools Manual.
