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

    o  To use the Wait qualifier, Oracle RMU requires that the
       database be recoverable for correct operation. It must be
       possible to attach to the database on a node where it is
       opened. There are database recovery failures that preclude
       further attaches to the database. When such a failure occurs,
       any attempt to attach to the database (for example, with an
       SQL ATTACH statement) causes the process to be deleted from
       the system. In other words, you are logged out.

       In this situation, the RMU Close command with the Wait
       qualifier has the same effect as the RMU Close command with
       the Cluster and Nowait qualifiers. The operation does not
       wait, and it does not close the database unless it is opened
       on the node from which you issue the Oracle RMU command.

       If you encounter this situation, enter the following command
       from a node on which the database is open to close the
       database:

       $ RMU/CLOSE/CLUSTER/NOWAIT/ABORT=DELPRC
