cannot find AIJ journal required to start replication

  Explanation:  Database replication using the Hot Standby feature
  was attempted to be started, but the AIJ journal required by the
  standby database could not be  found  on  the  master  database.
  This  typically  occurs  when  the  AIJ  Backup  Server  ("ABS")
  inadvertantly backs up the AIJ journal on  the  master  database
  following an AIJ switch-over operation.

  User Action:  The journal specified in the  Log  Catchup  Server
  ("LCS")  output  file  must  be  manually  rolled forward on the
  standby database.  Alternately,  the  master  database  must  be
  backed up and restored as the standby database.
