Parallel=(Executor_Count=n[,options])

    Specifies that you want to perform a parallel backup operation.
    When you issue an RMU Backup command with the parallel qualifier,
    RMU Backup generates a plan file. This plan file describes how
    the parallel backup operation should be executed. If you specify
    the Noexecute qualifier, the plan file is generated, but not
    executed. If you specify the Execute qualifier (or accept the
    default), the plan file is executed immediately after RMU Backup
    creates it.

    The Executor_Count specifies the number of worker executors you
    want to use for the parallel backup operation. The number of
    worker executors must be equal to or less than the number of tape
    drives you intend to use. If you specify Executor_Count=1, the
    result is a non-parallel backup operation that is executed using
    the parallel backup procedure, including creation of the plan
    file and a dbserver process.

    You can specify one, both, or none of the following options:

    o  Node=(node-list)

       The Node=(node-list) option specifies the names of the nodes
       in the cluster where the worker executors are to run. If more
       than one node is specified, all nodes must be in the same
       cluster and the database must be accessible from all nodes in
       the cluster.

       In addition, for a backup operation across nodes in a cluster
       to be successful, whoever starts SQL/Services must have
       proxy access among all nodes involved in the backup operation
       (assuming you are using DECnet). For example, if you specify
       the Nodes=(NODE1, NODE2, NODE3) as an option to the Parallel
       qualifier, whomever started SQL/Services must have access
       from NODE1 to NODE2, NODE1 to NODE3, NODE2 to NODE1, NODE2 to
       NODE3, NODE3 to NODE1, and NODE3 to NODE2.

       Separate node names in the node-list with commas. If you do
       not specify the Nodes option, all worker executors run on the
       node from which the parallel backup plan file is executed.

    o  Server_Transport=(DECnet|TCP)

       To execute a parallel backup operation, SQL/Services must
       be installed on your system. By default, the RMU Backup
       command uses DECnet to access SQL/Services; if DECnet is
       not available, RMU Backup tries to use TCP/IP. Use the
       Server_Transport option to set the default behavior such
       that RMU Backup tries TCP/IP first. You can also use the
       SQL_NETWORK_TRANSPORT_TYPE configuration parameter to modify
       the default behavior. See the Oracle Rdb Installation and
       Configuration Guide for details on setting the SQL_NETWORK_
       TRANSPORT_TYPE configuration parameter.

    o  Statistics

       Specifies that you want RMU Backup to gather statistics
       on the parallel backup operation for use with the Parallel
       Backup Monitor. You must invoke the Parallel Backup Monitor, a
       Windowing interface, to view these statistics.

    To execute a parallel backup operation, SQL/Services must be
    installed on your system. By default, the RMU Backup command
    uses DECnet to access SQL/Services; if DECnet is not available,
    RMU Backup tries to use TCP/IP. You can use the SQL_NETWORK_
    TRANSPORT_TYPE configuration parameter to set the default
    behavior such that RMU Backup tries TCP/IP first. See the Oracle
    Rdb Installation and Configuration Guide for details on setting
    the SQL_NETWORK_TRANSPORT_TYPE configuration parameter.

    Note that during a parallel backup operation, all tape requests
    are sent to the Operator; the parallel backup operation does not
    send tape requests to the user who issues the Backup command.
    Therefore, you should issue the DCL REPLY/ENABLE=TAPES command
    from the terminal that serves the operator before issuing the RMU
    Backup command.
