Hi,

I'm trying to create a physical standby database on my Oracle9i DB runing on WinXP.

Note: I have both Primary and Standby on the same system.

Actually everything went well .... I did created the standby DB but the problem is I can not start my primary DB if my standby DB is mounted. I get this error:
ORA-01102: cannot mount database in EXCLUSIVE mode

And when I read about the error message I learnt that I should start my DB in compatible mode ... please how do I do that?

Or possibly how can I make this work.

Regards,

Cherish

Hi
Same host, that too in windows, will create the problem like this. Better go for two different hosts. I have tried and failed. I was able to setup in two hosts successfully.

Thanks,

Hello
Hello please let me know how your issue is resolved

I am using windows oracle 11g i am trying to implement dataguard on same machine (primary and standby db on same machine)
I follow steps as below:

1)force logging primary
2)shutdown primary copy all datafiles to standby filesystem
3)editing listener and tnsnames for both primary and standby
4)editing init.ora for both primary and standby(for standby
modified and used init.ora of primary so db name etc same,only
parameters as below changed:
Primary:
=======


log_archive_dest_1
log_archive_dest_2
log_archive_dest_state_1
log_archive_dest_state_2
fal_client
fal_server
archive_lag_target
_log_archive_callout
#standby_archive_dest= ## UncDB1ment after switchover ##
#standby_file_management=auto ## UncDB1ment after switchover ##
#log_archive_dest_state_2=DEFER ## UncDB1ment after switchover ##

Standby:
=======
log_archive_dest_1=
log_archive_dest_state_1
log_archive_dest_2=
log_archive_dest_state_2=
standby_archive_dest=
standby_file_management=auto
fal_client=
fal_server=

Am i missing something or doing anything wrong please suggest
