I ran into issue while restoring RMAN backup to standby server.


channel d4: restoring datafile 00020 to +XN_DATA
channel d4: reading from backup piece /local/data/oracle/nfs/XNODBCOR/backupset/2011_07_28/o1_mf_nnndf_BKP_XNODBCOR_FULL_07_731qqngm_.bkp

Recovery Manager complete.

Oracle doc says, It occurs due to corrupt backup piece or some issues with reading from the OS layer.
Try to validate the backupset that was thrown by the error.

RMAN > validate backupset <bs_key>

BUT, in our case, I realized the backupset which is referred in the restored has pretty old time stamp. I had to change the incarnation to restore and recover successfully.

Run “list incarnation;” and switched to the correct one as below.

RMAN> reset database to incarnation 2;

database reset to incarnation 2

RMAN> run {
allocate channel d1 device type disk;
allocate channel d2 device type disk;
allocate channel d3 device type disk;
allocate channel d4 device type disk;
restore database;
switch datafile all;
switch tempfile all;
recover database;
