How to solve ORA-19505: failed to identify file in RMAN?

DBA’s will feel bad when they got any error. It’s common for any :)

Lets say you got below error

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ch00 channel at 01/17/2011 13:01:03
ORA-19505: failed to identify file “/dwh1/oraarch/arch/1_1100721_664058960.dbf”
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory

Don’t be panic, nothing happened to your backup or database. If you read the error, its saying particular archive logfile is not available. This may be due to file deleted at OS level due to some reason.

In this situation, do the following

1. Run crosscheck command against archivelogs

RMAN> crosscheck archivelog all;

2. If you find any archives marked as EXPIRED, then delete those expired archives using below command

RMAN> delete expired archivelog all;
This will prompt you YES or NO. If you don’t want a prompt, use below command

RMAN> delete noprompt archivelog all;

3. Take a fresh archivelog backup

RMAN> backup archivelog all; (you  can use delete input clause also)
