ORA-19573: cannot obtain exclusive enqueue for datafile 1

I got the following error while applying the incremental backup to the standby database “ORA-19573: cannot obtain exclusive enqueue for datafile 1”. This was very annoying as i have cross checked everything many times. Here is few lines from RMAN sessions from which applying incremental backup:


channel ORA_DISK_4: reading from backup piece /oraclebackup/PLMQDBS/inc/incr_for_stdby_f7o3u54k_1_1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 03/07/2013 12:39:20
ORA-19870: error while restoring backup piece /oraclebackup/PLMQDBS/inc/incr_for_stdby_f4o3u54k_1_1
ORA-19573: cannot obtain exclusive enqueue for datafile 1

Well, error was because of very silly mistake, i forgot to cancel the media recovery process before starting the RMAN incremental apply session. Once i have cancelled the recovery process as below, incremental backup ran fine.

oracore@myhost $ sqlplus /nolog
