Rem  NAME
Rem    mgwd920.sql - MGW downgrade script (9.2.0.x reload script)
Rem
Rem  DESCRIPTION
Rem    Downgrade Messaging Gateway from MGW/RDBMS Release 10.0.0 to 9.2.0.
Rem
Rem    This is effectively the MGW component reload script (mgwrelod.sql)
Rem    for RDBMS 9.2.0.x release. As of RDBMS 10.0.0, a mgwdNNN.sql script
Rem    should no longer be needed.
Rem
Rem  NOTES
Rem    This script must be run AS SYSDBA.
Rem
Rem    This script must be run from the MGW admin directory of the Oracle
Rem    9.2.0.x release ($ORACLE_HOME/mgw/admin).
Rem
Rem    This script is intended to be run in the context of a 9.2.0.x 
Rem    database after it has been downgraded from 10.0.0. It should be run
Rem    ONLY if the Messaging Gateway component (MGW) was loaded for the 
Rem    10.0.0 database. It does not need to be run if the MGW component
Rem    was never loaded.
Rem
Rem    Messaging Gateway agent must be shut down before running this script.
