Hello Dear,

I am new into Datagurad technology , I have some confusion.Please help
@Primary
SQL> select max(sequence#) from v$log_history;

MAX(SEQUENCE#)
--------------
        471983

@standby
SQL> select max(sequence#) from v$log_history;

MAX(SEQUENCE#)
--------------
        471911

@standby
SQL> select LOW_SEQUENCE#, HIGH_SEQUENCE# from V$ARCHIVE_GAP ;

no rows selected

SQL> select name , value from V$DATAGUARD_STATS where name like '%lag';

NAME                             VALUE
-------------------------------- ----------------------------------------------------------------
transport lag                    +00 00:08:43
apply lag                        +00 06:29:31

Can you please let me know , my dataguard is in sync with primary or not because there is no V$ARCHIVE_GAP ; but V$DATAGUARD_STATS shows lag time. Can you please let me know what I should do in this case.

Thanks,

Please use [code] tags in your posts. You have been asked to do this before. Also I notice that you never responded to replies to your previous question, http://www.orafaq.com/forum/m/668392/#msg_668392 which makes me wonder if you are interested in what I say.

In this case, you need to query v$managed_standby to see what is going on.

I think create a test table and check on standby is one good method!
