We are running 2 db servers 11G on RH 6.3 and 12C on 7.4. We noted an issue with our 11G backups due to the way that a windows cifs share was mounted.
The symptom was noted in trying to do a restore to a point in time last week .
On 11G we had to catalog the backups files rman> catalog start with '/engbkup_one/<ora_sid>_db/backupset/'; which then proceeded to list the files and on cataloging reports:
RMAN-07517: Reason: The file header is corrupted for each file. In digging into this we noted Oracle doc id 2-94368.1 which specs to mount windows cifs shares using directio option.
We've done this on both 11g and 12C servers.
On the 11g box, I'm in the process of creating a new backup to see if the problem persists. On the 12C host, I created a new backup but running rman> catalog start with '/engbkup_one/<ora_sid>_db/backupset/'; returns :
"searching for all files that match the pattern /engbkup_one/gdmstest_db/backupset/
no files found to be unknown to the database"
On the 12C running rman>crosscheck backuppiece does return a list of backup pieces. The files can also be seen from the local OS.
Why is running " rman> catalog start with ......" returning no files?
