Converts any of the following versions (or any of the mandatory
    updates to these versions) of Oracle Rdb databases to an Oracle
    Rdb release 7.2 database:

    o  Version 7.0

    o  Version 7.1

    See the Oracle Rdb Installation and Configuration Guide for the
    proper backup procedure prior to installing a new release of
    Oracle Rdb and converting databases.

                                   NOTE

       The following are important issues to consider when you
       convert a database:

       o  A database must be backed up immediately following an
          Oracle RMU convert operation.

          A database converted using the RMU Convert command may
          not be recoverable if a full database backup is not made
          immediately after the convert operation completes. If you
          attempt to restore a database using a backup file created
          prior to the conversion, the database may be left in an
          unrecoverable state.

       o  If after-image journaling is enabled when you issue
          the Convert command, Oracle RMU disables after-image
          journaling during the convert operation and then does
          one of the following, depending on the type of .aij file
          or files being employed when the Convert command was
          issued:

          -  If an extensible .aij file was being used, Oracle RMU
             creates a new journal for the converted database and
             enables after-image journaling.

          -  If fixed-size .aij files were being used, Oracle RMU
             activates the next available fixed-size journal and
             enables after-image journaling. If another fixed-
             size journal is not available, journaling remains
             disabled.

          Use only the .aij file (or files) created or activated
          during or after the convert operation together with the
          backup file you created immediately after the convert
          operation to restore and recover your database. Any .aij
          files created prior to the Convert operation cannot be
          used to recover the converted database.

          If you issue an RMU Convert command with the Rollback
          qualifier, Oracle RMU disables after-image journaling
          and returns the message: RMU-I-CANTENAAIJ. Oracle
          Corporation recommends that you back up the database and
          enable after-image journaling when the convert operation
          completes.

       o  Growth of the RDB$SYSTEM storage area is normal during
          a convert operation. You must be sure that there is
          sufficient disk space for the new metadata and the
          converted metadata.

          During a convert operation Oracle RMU makes an upgraded
          copy of the metadata. If the convert operation fails,
          the old metadata is available for rolling back. If
          you specify the Nocommit qualifier, both copies of
          the metadata exist at the same time (to allow a manual
          rollback operation). If you specify the Commit qualifier,
          the old metadata is deleted once the convert operation
          completes successfully.

    Read the Description help entry under this command carefully for
    important information on converting single-file and multifile
    databases.
