Problem : Oracle RMAN backup of archivelogs
Hi,
I tend to do an RMAN coldback of my DB using a “backup database” command in RMAN and it works fine.
I am trying to use RMAN to backup the archivelogs but it keeps spitting out the following errors:
ORA-19715: invalid format c for generated name
ORA-27302: failure occurred at: slgpn
I got it to run if I used the format option and specified the output without any format parameters but it then failed once it got to the backing up the control and spfile’s.
Can someone please tell me what I am doing wrong and how to correct?
I would also be interested to see examples of anyones RMAN scripts if they are willing to share, if not.. no worries 🙂
Code Snippet:

Solution : Oracle RMAN backup of archivelogs
Try to follow the following format which I use successfully on many environments. Note the difference between my CHANNEL DEVICE and yours.
Additionally, when I backup my archivelog I simply use
RMAN> backup archivelog all delete input; (this deletes the archvielogs once it is successfully backed up.
No need to specify location since it’s already configured.
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ‘/reco/rman/mdr/other/%F’;
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT ‘/reco/rman/mdr/data/%U’ MAXPIECESIZE 2 G;
