OGG-00446 No data selecting position from checkpoint table gguser.ckpt for group 'REP1', key 3066872255 (0xb6ccc1bf), SQL .

Cause: It appears replicat is not registered on CHECKPOINTTABLE (is’t true, it’s registered)

Solution: As a workaround we can ALTER the replicat to the same checkpoint location when we do an INFO REP , DETAIL and then START.
