Problem: If Alert Log File Reads – “Errors in file /u01/app/oracle/admin/qrcl/udump/qrcl_rfs_3724.trc” and RFS process is missing at the Standby end and you discovered difference in Archived Log Sequence.
Resolution: Export Archive logs from Primary DB side to Standby location and start recovery process on the Auxiliary end.
Exit managed recovery mode, add the logs, and then reinitiate managed recovery:
alter database recover managed standby database cancel;
[oracle@prashant1 2012_09_04]$ pwd
/u01/app/oracle/flash_recovery_area/QRCL/archivelog/2012_09_04
[oracle@prashant1 2012_09_04]$ scp * oracle@prashant2:/u01/app/oracle/flash_recovery

Start the managed recovery operation:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
Recheck Log Sequence and Status/Process from v$Managed_standby and you’ll find the RFS process back again along with ARCH & MRP/MRP0.
