Allows you to temporarily suspend .aij backup operations on all
    database nodes. While suspended, you cannot back up .aij files
    manually (with the RMU Backup After_Journal command) nor will the
    AIJ backup server (ABS) perform .aij backup operations.

1  –  Description

    When you issue the RMU Server Backup_Journal Suspend command,
    after-image journal (AIJ) backup operations are temporarily
    suspended. However, the suspended state is not stored in the
    database root file. Thus, if the node from which the AIJ backup
    operations were suspended fails, then AIJ backup operations by
    the AIJ Backup Server (ABS) are automatically resumed (assuming
    the ABS was running prior to the suspension).

    The purpose of RMU Server Backup_Journal Suspend command is to
    temporarily suspend AIJ backup operations during a period of
    time when backing up .aij files would prevent subsequent commands
    from operating properly. For example, if you have a Hot Standby
    database, the time from when the master database is backed up
    to the time that database replication could commence might be
    long. During this period, .aij backup operations would prevent
    the replication from starting. (See the Oracle Rdb7 and Oracle
    CODASYL DBMS: Guide to Hot Standby Databases for information on
    Hot Standby databases.)

    The solution to this problem is to use the RMU Server Backup_
    Journal Suspend command to suspend AIJ backups from the time
    just prior to beginning the database backup until after database
    replication commences.

    AIJ backup operations are suspended until any of the following
    events occur:

    o  The database is closed on the node from which AIJ backup
       operations were suspended.

    o  The node fails from which AIJ backup operations were
       suspended.

    o  Database replication is started on the node from which AIJ
       backup operations were suspended, as a master database.

    o  AIJ backup operations are explicitly resumed on the node from
       which AIJ backup operations were suspended. (This occurs when
       you issue the RMU Server Backup_Journal Resume command. See
       the Server_Backup_Journal help entry for details.)

                         x
  /[No]Log               x     Current DCL verify value

3  –  Parameters

3.1  –  root-file-spec

    Specifies the database root file for which you want to suspend
    AIJ backup operations.

4  –  Command Qualifiers

4.1  –  Log

    Log
    Nolog

    Specifies whether the processing of the command is reported to
    SYS$OUTPUT. Specify the Log qualifier to request log output and
    the Nolog qualifier to prevent it. If you specify neither, the
    default is the current setting of the DCL verify switch. (The DCL
    SET VERIFY command controls the DCL verify switch.)

5  –  Usage Notes

    o  To use the RMU Server Backup_Journal Suspend command for a
       database, you must have RMU$OPEN privilege in the root file
       access control list (ACL) for the database or the OpenVMS
       WORLD privilege.

    o  To determine whether AIJ backup operations have been
       suspended, use the RMU Show Users command.

6  –  Examples

    Example 1

    The following example first suspends .aij backup operations, then
    issues the RMU Show Users command to confirm that suspension has
    occurred. If you attempt an .aij backup operation, you receive
    the %RMU-F-LCKCNFLCT error message.

    $ RMU/SERVER BACKUP_JOURNAL SUSPEND MF_PERSONNEL.RDB
    $ RMU/SHOW USERS MF_PERSONNEL.RDB
     . . .
        * After-image backup operations temporarily suspended
          from this node
