Hi all,

We are in the phase of implementing EMC Networker backup for Oracle 11g 
realease 2. The idea is to backup the Fast Recover Area (FRA) to the tape every 
day.
In order to synchronize Tape catalog with the RMAN catalog; we are thinking to 
disable the RMAN retention policy and use the Tape Catalog. Which means; we 
want to use only the NetWorker server policy, and thus disable the Oracle 
retention policy with the following command:
configure retention policy to none;
I believe by using this, every time we backup to tape we have to crosscheck 
backup and delete obsolete from the tape, but, by doing this, How the Networker 
will delete the files and know which files are oboslete from the Oracle Catalog?
I would like to understand this phase.

Thank you
