Error in Standby

Question

Hi,
RAC Database - 11.2 , Standby - 11.2
There was not much space in the archive destination of the primary database, so moved few archive logs to a diff destination within the same server. Few archivelogs were backed by RMAN after the sequence 37635, since
archivelogs from seq from 37631 to 37634 were in a diff destination. Now the standby is comlplaining abaout the seq 37631.
Standby database is unable to fetch an archivelog from the primary database " Fetching gap sequence in thread 1, gap sequence 37631-37730 ".
So i moved the archivelogs from seq 37631 to 37634 were moved to their original destination. The archivelog - 37631 is present in the archive destination of the primary database.
However, still the standby database is unable to find these archivelogs.
Crosschecked the archivelogs, but its unable to run crosscheck on these 4 archivelogs.
First thought to backup these archivelogs and then to restore it back. But RMAN is unable to find these archivelogs :
RMAN> backup archivelog from logseq 37631 until logseq 37634 thread 1;
Starting backup at 06-04-2012 07:47:00
using channel ORA_DISK_1
using channel ORA_DISK_2
specification does not match any archived log in the repository
backup cancelled because there are no files to backup
Finished backup at 06-04-2012 07:47:01
Thanks

There was not much space in the archive destination of the primary database, so moved few archive logs to a diff destination within the same server. Few archivelogs were backed by RMAN after the sequence 37635, since

Crosschecked the archivelogs, but its unable to run crosscheck on these 4 archivelogs.Does this RMAN will backup & delete or just backup?
If just backup then fine, Once after you moving archives to the original location.
Still standby is an impression as there is GAP, so better if you bounce MRP.
First thought to backup these archivelogs and then to restore it back. But RMAN is unable to find these archivelogs :First check where physically exist, also check from v$archived_log;
once you move to the original location, this step no need still better you catalog them again.
RMAN> crosscheck archivelog all;
RMAN> delete expired archivelog all;
- now make sure all the archives exist in archive destination, then
RMAN> catalog start with 'archive location';
This command will search for all the archives, if any new archives found then it will register it.
You have less archive gaps, so you are fine with this procedure, or restore archives from backup and SCP to standby and then perform recovery.
Also you can check procedure of incremental roll forward http://www.oracle-ckpt.com/rman-incremental-backups-to-roll-forward-a-physical-standby-database-2/
HTH.
