HELPLIB.HLB  —  RMU72  Hot Standby, Default Command Qualifiers
    The Hot Standby software supplies default values for most of the
    master and standby database attributes and maintains them in the
    database root file. Optionally, you can change one or more of the
    database attributes using qualifiers on the Replicate commands.
    When you specify a database attribute, the Hot Standby software
    updates the database root file so that the database root file
    always contains the most up-to-date qualifier values for the
    database.

    You can specify database attributes using qualifiers on either of
    the following Replicate commands:

    o  Replicate After_Journal Configure-Preconfigures the master
       and standby database attributes without starting replication
       operations. This optional command allows you to preset
       database attributes that do not take effect until the next
       time you start replication operations using the Replicate
       After_Journal Start command.

    o  Replicate After_Journal Start-Configures database attributes
       at the same time you start replication for a database. If you
       preconfigured your database previously using the Replicate
       After_Journal Configure command, you can override the default
       settings by including one or more qualifiers on the Replicate
       After_Journal Start command.

    Whenever you enter the Replicate After_Journal Start command,
    the Hot Standby software initiates database replication using
    the qualifier values specified on the Replicate After_Journal
    Start command line. If you do not specify qualifier values on the
    command line, the Hot Standby software uses values stored in the
    database root file or the default value for the qualifier.

    Therefore, you do not need to respecify the qualifier values
    except to change a qualifier setting. For example, the following
    command example shows the Replicate After_Journal Start command
    the first time you enter it on the master database node:

    $ RMU/REPLICATE AFTER_JOURNAL START mf_personnel -
         /STANDBY_ROOT=REMNOD::DISK1:[USER]standby_personnel -
         /SYNCHRONIZATION=HOT

    The Hot Standby software saves the qualifier settings in the
    database root file (in this case, the database attributes are
    saved in the master database root file). The next time you start
    replication operations, you could enter the command line without
    the qualifier.
