After register dthe db in catalog, I tried a full backup, but for default I read the snapshot controlfile is under $ORACLE_HOME/dbs in one node of rac environment.
I try to change it, by command
RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+RECO_II01/DBASSET/CONTROLFILE/snapcf_ASSE1.f';
I receive error:
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-03002: failure of configure command at 12/27/2012 12:31:41

When I try to return to default, I receive the same error.
