You'll need to allocate either a disk or tape channel for RMAN to use which is what the error message is trying to tell you. Using the allocate channel statement you can do this: allocate channel fra_d1 type disk; as an example. Once you have at least one channel allocated try the backup command again.

Thanks Niall and Dimitre for replying. I could not find a command for list backupiece (without knowing the names of pieces). I did a full 'list backup' to see the backup pieces it displays at the end - but no luck there. It says all the files are in 'FLASH' and shows the deleted ones as expired correctly. I tried Dimitre's suggestion and got this: * RMAN> backup recovery area; Starting backup at 28-MAR-12 specification does not match any archive log in the recovery catalog specification does not match any datafile copy in the repository RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of backup command at 03/28/2012 17:26:19 RMAN-06747: at least 1 channel of tertiary storage must be allocated to execute this command * I tried to check this command in another database where things are good, but I got the same response. Not sure what this command does. I am inclined to think that this is a bug. I need to work on that more. ------------------------------------------------------------------------------------ On Wed, Mar 28, 2012 at 1:26 PM, Radoulov, Dimitre <cichomitiko@xxxxxxxxx>wrote: > On 27/03/2012 00:53, Ram Raman wrote: > >> v10.2.
