ORA-38706 ORA-38788 on setting flashback on in standby database
HI Friends,
We are setting up dg and dg is working well, all in sync.
Then we turn flashback on in the standby database,
alter database flashback on
ORA-38706: Cannot turn on FLASHBACK DATABASE logging.
ORA-38788: More standby database recovery is needed
ORA-38706 signalled during: alter database flashback on...
no transport lag
no apply lag
no file corruption
incarnation is the same as in primary.
stop apply and transport, turn flashback again in standby db, still same error.
Please advise
Appreciated
Friendly
