We are trying to implement encryption for our Oracle database backups.
We are running Oracle 9i with TSM 5.3.0 .  We created 
a test database, turned on encryption, run a database backup and do a
restore validate on it with out any issues.  I can turn on
an API trace to verify that we are in fact encrypting the data.  If I
run the same scenario on our production database, I receive 
the folloiwng error message in the RMAN error log: 

RMAN-3002 failure of restore command at ....
ORA-06510 PL/SQL: unhandled user-defined exception

The only difference I can see is that in the first senario we are using
TDP for Oracle: version 2.2.0.0 and for the production
database we are using TDP for ORACLE: version 2.2.0.2

Does anyone have any experioence with this?

Thanks,
Marty
