    Nolog

    Indicates whether or not to log the status of, and information
    about, activities when you start replication operations.

    Applicable to:              Master and standby database
    Required or Optional:       Optional
    Default Value:              Nolog

    If you specify the Log qualifier, output showing the status
    of the replication startup is logged to SYS$OUTPUT on OpenVMS
    systems.

    Oracle Corporation recommends that you specify the Log qualifier.

    Also, you can record status information to an output file by
    including the Output qualifier on the Replicate After_Journal
    Start command.
