Warning message for backup
oracle-00105 failed to uncatalog /opt/NTAPsmo/mnt/-dsk01/20090810/oradata/rtest/100_D01_33.dbf from RMAN. Most likely the file has already been uncatalogued manually or by another process, but it may need to be manually removed.
I am not very familiar with RMAN. How can I check if the file has been uncatalogued? What do I need to manually remove? Thanks for your help.
