RMAN duplicate failed, can I rerun it and keep files?

RDBMS 19.15

RHEL 8

Hi,

I ran this script

run

{

set newname for datafile 1 to '/opt/oracle/oradata/testdb01/data.7825';

...

DUPLICATE DATABASE TO testdb01

BACKUP LOCATION '/mnt/test/prodbackup/'

NOFILENAMECHECK;

}

But it failed in the end with:

RMAN Duplicate failing with RMAN-06136, ORA-01503, ORA-00349 (Doc ID 2206423.1)

RMAN-06136: ORACLE error from auxiliary database: ORA-01503: CREATE CONTROLFILE failed

ORA-00349: failure obtaining block size for '+DISK1'

I have hopefully fixed the error, but if not, is it possible to rerun and keep the files already on disk? The data of the backup has not changed.

Regards

Rookie
