how to clear in rman configure db unique name connect identifier in a non catalog envorpnment
I am running a test database oracle 19.C15 enterprise edition on Redhat 7.
I have recently finished testing a dataguard environment and have been able to reset most of the configuration parameters for RMAN except:
CONFIGURE DB_UNIQUE_NAME 'PRIM1' CONNECT IDENTIFIER 'PRIM1-TNS-ALIAS';
I use the controlfile to keep the RMAN information. I have read instructions about changing this parameter but all are given for someone using a catalog, you just unregister the database from the catalog, seems simple enough. I just can't find how to I clear this parameter.
How do I clear this parameter?
Thanks,
Claudia
