"RESYNCHRONIZATION" means you have a gap in applied archive logs. Run this on your primary:

SELECT LOCAL.THREAD#, LOCAL.SEQUENCE#
FROM (SELECT THREAD#, SEQUENCE#
      FROM V$ARCHIVED_LOG
      WHERE DEST_ID=1) LOCAL
WHERE LOCAL.SEQUENCE# NOT IN
  (SELECT SEQUENCE# FROM V$ARCHIVED_LOG
   WHERE DEST_ID=2 AND THREAD# = LOCAL.THREAD#);

Copy the missing logs to the standby and manually resolve the gap.


I do not know how to resolve the issue if you have already deleted the logs on the primary. Someone else on the list may have some ideas.
