Displays information about transaction logs.

    Requires READ access to the transaction logs and the directories
    they are in.

    Format

      SHOW LOG  [filespec]

1  –  Parameter

 filespec

    The file specification of the transaction logs you want to
    display information about. This can include the percent (%) and
    asterisk (*) wildcard characters.

    The SHOW LOG command uses the following defaults:

    o  If you omit the disk and directory, the SHOW LOG command
       looks for the transaction log in the directories pointed to
       by SYS$JOURNAL, which must be defined in executive mode in the
       system logical name table.

    o  If you omit the file type, the SHOW LOG command uses
       .LM$JOURNAL.

2    /CURRENT

    Displays information about the local node's transaction log. This
    includes the number of checkpoints and stalls that have occurred
    since DECdtm services started on this node.

    To use the /CURRENT qualifier:

    o  You must have the CMKRNL privilege.

    o  You must omit the parameter to the SHOW LOG command.

3    /FULL

    Lists all attributes of the transaction logs. For each
    transaction log, both the full file specification of the
    transaction log and its size are displayed.

    If you do not specify which transaction log you want to display,
    the SHOW LOG command lists all transaction logs of the form
    SYSTEM$*.LM$JOURNAL, in all directories pointed to by the logical
    SYS$JOURNAL, which must be defined in executive mode in the
    system logical name table.

4    /OUTPUT

       /OUTPUT[=filespec]

    Requires READ and WRITE access to the directory in which the
    output file is to be created.

    Specifies where the output of the SHOW LOG command is sent. If
    you omit this qualifier, output is sent to the current SYS$OUTPUT
    device (usually your terminal). To send the output to a file, use
    the /OUTPUT qualifier. If you do not supply a file specification,
    the output is sent to the file LMCP_SHOW.LIS in your default
    directory.
