RMAN Crosscheck taking too long

RMAN Crosscheck taking too long.

Case 1: Nocatalog

SQL> select count(*) from v$deleted_object;

Gives the no. of deleted backup objects

SQL> exec dbms_backup_restore.resetcfilesection(19);

Section 19 is for backup and it's being reset.

Executing above sql query given 0 rows selected

Now initiated crosscheck and it's running little faster as compared to old.

Need to monitor for a while...
