    o  Add, drop, modify, or reserve .aij files.

    o  Suppress the use of an .aij file.

    o  Add AIJ caches.

    o  Set the initial .aij file allocation.

    o  Set the .aij file extent (for extensible journals).

    o  Enable or disable .aij file overwriting.

                                   NOTE

       Prior to Oracle Rdb Version 6.0, the ability to alter an
       .aij file name was provided through the RdbALTER DEPOSIT
       ROOT command. Beginning with Oracle Rdb Version 6.0, the
       RdbALTER DEPOSIT ROOT command no longer provides this
       capability; use the Alter qualifier with the RMU Set After_
       Journal command instead.
