filespec

    The file specification of the transaction log to be created.

    For DECdtm services to use the transaction log, the file must
    have a name of the form SYSTEM$node.LM$JOURNAL, where node is the
    name of the node.

    The CREATE LOG command uses the following defaults:

    o  If you omit the disk and directory, the CREATE LOG command
       creates the transaction log in the first accessible directory
       pointed to by the logical SYS$JOURNAL, which must be defined
       in executive mode in the system logical name table.

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

    If you specify a disk and directory not pointed to by SYS$JOURNAL
    a warning message is displayed. However, the transaction log is
    still created, but will not be used until either:

    o  SYS$JOURNAL is modified to point to the disk and directory
       where the log was created, or

    o  You move the new transaction log to a directory pointed to by
       SYS$JOURNAL.
