ORA-19606: Cannot copy or restore to snapshot control file
exit;
Recovery Manager complete.
google found some questions, but not fittung answers.
So far:
- I checked the folder & users rights.
- I found some /tmp/ files - yes I "backup" the backuped archivelogs to-delete files in /tmp - I only active archivelogmode so I can onlinebackup
- I managed to login via rman and execute DELETE OBSOLETE manual - result above.
- Actual I delete the set one by one to find the problem set. (delete backupset 12345 ) from the list manually.
Some a good idea what went wrong?
additional: Is there a way to let oracle delete the empy archvielog-directories after deleting the logs within?
18:00- the command "RMAN> BACKUP CURRENT CONTROLFILE" also fails.

Answer 1

Meanwhile I managed to delete all backupsets one by one.
The problem with $ORACLE_HOME/dbs/snapcf_<SID>.f persists.
cd $ORACLE_HOME/dbs
mv snapcf_<SID>.f snapcf_<SID>.f.bak
# replaced actual dbsidname with <SID>

ORA-19606: Cannot copy or restore to snapshot control file
No different effect, if I changed the filename via 2nd terminal to .bak or not.
RMAN> delete controlfilecopy 3831;
will fail, if the file exists or not.
Any chance to reset/kill that file?
Is there a need to restart the dbms after rename the file?
