After upgrading database from to 11.2.03, where all post-upgrade checks have worked, the offline backups through RMAN  fail at database startup

Two instances are on the same server using an ORACLE_HOME of /opt/oracle/product/11.2.0/dbhome_1.
Assume the instances are called DBtest1 and DBorcl1.

There is one listener for both instances/databases runing from the above ORACLE_HOME.

After applying patch, instance DBtest1 was configured to use the ORACLE_HOME /opt/oracle/product/11.2.0/dbhome_2.  All the config files for DBtest1 were copied from dbhome_1 to dbhome_2

DB-Control for DBTEST1 ( is running ok, although it doesn't monitor the listener as this is still running off dbhome_1.
DB-Control for DBORCL1 ( is running ok, and it does monitor the listener as this is still running off dbhome_1.

When performing an offline RMAN backup for DBtest1, the following sequence of events occur:

- The database is shutdown successfully by the rman script, but fails on startup.
- The rman log has the RMAN-04014 startup failed ORA-03113 end-of file on communications channel.
- The alert.log has no error messages for startup, the startup has begun but after a few lines there is nothing further in the alert.log.
- Shutdown abort for DBtest1 11203 database completes successfully
- Startup for DBtest1 then completes successfully, and the instance operates normally.
