Where in the command sequence did you see this message? You don't put timestamps at the 9 commands.

Wat's in the file /SRV_ACE/server/database/bdump/srv_ace_arc0_16980.trc?

I see the 3113's pretty often in my trace's. The shutdown of the standby kills the RFS proces. The primary therefore can no longer communicate with this proces, responsible for receiving the redo and writing it to disk. ORA-3113 is well resembling that state transition.

Maybe I wouldn't defer the destination. Depending on your further settings it will automagically resume once you restart the standby. If you plan to keep the standby shutdown for a longer time deferring makes sense.

Best regards,

Carel-Jan Engel

Thanks - Now I had another problem:

on primary: alter system set log_archive_dest_state_2=defer scope=both;
on primary: alter system switch logfile;
on standby: alter database recover managed standby database cancel;
on standby: shutdown immediate;
on standby: startup nomount;
on standby: alter database mount standby database;
on standby: alter database recover managed standby database disconnect from session;
on primary: alter system set log_archive_dest_state_2=enable scope=both;
on primary: alter system switch logfile;

Immediately, I saw the following in the alert log - I guess this is normal?

Errors in file /SRV_ACE/server/database/bdump/srv_ace_arc0_16980.trc: ORA-03113: end-of-file on communication channel

BTW, is this the right procedure to shutdown a standby?

Thanks,

Roger
