That you get this message on your primary database suprises me a little. In my experience the primary is somewhat a 'normal' database with an extra remote archive_log destination. Do I understand correctly that these database reside on the same host? My first guess (always my worst), is that somehow the redolog files are mixed up/ used by both databases. Problems I would expect on the secondary node. Maybe you can supply some values from the init-file from both primary and secondary node, so we maybe can see some misconfiguration. Ow...and the tns names? Probaly the more interesting parameters to have a look at are: db_name DB_UNIQUE_NAME dg_broker_config_file1 <== But I guess you do not have DG_Broker configured allready dg_broker_config_file2 <== But I guess you do not have DG_Broker configured allready dg_broker_start=TRUE <== But I guess you do not have DG_Broker configured allready fal_server log_archive_config LOG_ARCHIVE_DEST_1 LOG_ARCHIVE_DEST_2 LOG_ARCHIVE_DEST_STATE_1 log_archive_dest_state_2 Anyway...as Andrew Kerber also said, I have spend numerous hours cursing DG, just to find a misspelling or relalizing that I misunderstood the scenario :-( Best Regards, Martijn On Wed, May 29, 2013 at 03:25:23PM -0400, Scott Canaan wrote: > Primary. > Scott Canaan '88 (srcdco@xxxxxxx<mailto:Scott.Canaan@xxxxxxx>) > (585) 475-7886 - work (585) 339-8659 - cell > "Life is like a sewer, what you get out of it depends on what you put into > it." - Tom Lehrer. > > From: Andrew Kerber [mailto:andrew.kerber@xxxxxxxxx] > Sent: Wednesday, May 29, 2013 3:23 PM > To: Scott Canaan > Cc: oracle-l@xxxxxxxxxxxxx > Subject: Re: Data Guard Configuration > > On the primary or the standby? > > On Wed, May 29, 2013 at 2:18 PM, Scott Canaan > <srcdco@xxxxxxx<mailto:srcdco@xxxxxxx>> wrote: > This is what I keep getting: > > SQL> startup > ORACLE instance started. > > Total System Global Area 409251840 bytes > Fixed Size 2228744 bytes > Variable Size 264244728 bytes > Database Buffers 134217728 bytes > Redo Buffers 8560640 bytes > Database mounted. > ORA-00314: log 5 of thread 1, expected sequence# 35 doesn't match 0 > ORA-00312: online log 5 thread 1: > '/oracle/data/LNX8TEST/mirror_files/redo05b.log' > ORA-00314: log 5 of thread 1, expected sequence# 35 doesn't match 0 > ORA-00312: online log 5 thread 1: '/oracle/data/LNX8TEST/redo05a.log' > > > SQL> > > Scott Canaan '88 (srcdco@xxxxxxx<mailto:Scott.Canaan@xxxxxxx>) > (585) 475-7886<tel:%28585%29%20475-7886> - work (585) > 339-8659<tel:%28585%29%20339-8659> - cell > "Life is like a sewer, what you get out of it depends on what you put into > it." - Tom Lehrer. > > From: Andrew Kerber > [mailto:andrew.kerber@xxxxxxxxx<mailto:andrew.kerber@xxxxxxxxx>] > Sent: Wednesday, May 29, 2013 3:14 PM > To: Scott Canaan > Cc: oracle-l@xxxxxxxxxxxxx<mailto:oracle-l@xxxxxxxxxxxxx> > > Subject: Re: Data Guard Configuration > > In my experience, if you are fairly confident that you followed the steps > properly, the issue is almost always network/tns configuration.
