When using the log_file_name_convert parameter in creating a standby database, how can I configure my init.ora parameter file of the standby database on a different host to reference multiple redolog files on different mount points??
Thanks

Can someone MODERATORS please help with this???
Thanks
Are you getting any errors, or just would like to have some information on the configurations ?

When you create stanby DB you must place all files, including LOG in come directory structure ac primary DB.
if uoy place db files and log files in another dir structure you must set 2 parameters for convers full file names with path for DB and LOG on standby DB box:
db_file_name_convert
log_file_name_convert
for more information read classic books (Oracle Documentation library)

SAM and others thanks!!!
My problem is this:
My primary database has two online logfile groups
/u01/oradata/prod/redo01a.log
/u01/oradata/prod/redo02a.log
/u02/oradata/prod/redo01b.log
/u02/oradata/prod/redo02b.log
In the standby init.ora file, Oracle only allows the use of LOG_FILE_NAME_CONVERT just once and as follows:
log_file_name_convert='/u01/oradata/prod', '/u01/oradata/standby'
Which converts the logs in /u01/oradata/prod in the primary to /u01/oradata/standby of the standby host
Now, my question is, how do I convert the logs in /u02/oradata/prod files???? When I put two LOG_FILE_NAME_CONVERT in the standby init.ora file, I get an error.
Please moderators help!

Sam Thanks again, I have just tried your recommendation and now the instance start command gives the following error:
SQL> startup nomount pfile=initstandbydb.ora
ORA-01678: parameter log_file_name_convert must be two strings, a pattern and a replacement
Doesn't like syntax...I still don't know how to convert for multiplexed logs...any more suggestions???
You may use convert string like this one:
log_file_name_convert='/u0*/oradata/prod/redo*.log', '/u0*/oradata/standby/redo*.log'
and use some convert rules for DB files
db_file_name_convert='/u0*/oradata/prod/data_file*.ora', '/u0*/oradata/standby/datafile*.ora'
Folks
The preceding suggestion still did not work, any more ideas???
Try next version:
Log_file_name_convert="/u0*/oradata/prod","/u0*/oradata/standby"
log_file_name_convert= (('/u01/oradata/prod', '/u01/oradata/standby'),('/u02/oradata/prod', '/u02/oradata/standby'))
use double quotes not single quotes like
log_file_name_convert= ((''/u01/oradata/prod'', ''/u01/oradata/standby''),(''/u02/oradata/prod'', ''/u02/oradata/standby''))
It shud work
Just to prevent anyone reading this thread from making the mistakes propogated...the above "answer" by sonofsita is incorrect.
The proper method is to list each log_file_name_convert on a separate line, such as:
log_file_name_convert=('/u01/oradata/prod', '/u01/oradata/standby')
log_file_name_convert=('/u02/oradata/prod', '/u02/oradata/standby')
While sonofsita provided information that is incorrect,
it is also worth noticing that this is a 14 year old thread.
Also it could be that sonofsita had the commands stored in
a string and was dynamically building SQL. Hence could
be why the extra ticks were present.
I realize you're a moderator but what does BAD information have to do with WHEN it was given? The reason that I put the PRESCRIBED way to do it is so some newbee wouldn't spend his/her time chasing their tail because the method used was incorrect.Quote:

Jeez. Go moderate something and leave someone, who was trying to prevent other's errors due to erroneous information, a break.
I appreciate your enthusiasm for fixing mistakes of the past and I am not trying to make you go away.
Stay and post as much as you like. Even though I am a moderator on this site I am forced to Google
as much as anyone else. If I am looking for information related to a 11g or 12c database, I tend to
only look at posts from the last 5 years, ideally the last 2 years.
If someone who is new to Oracle is looking for information about creating a database and they find
a post talking about sizing rollback segments and dictionary managed table spaces they will probably
get confused because those things went away starting with 9i and ultimately 10g. They may also
realize that in the realm of software any answer in any post that you see has an expiration date,
and it is not worth while looking too far back. Unless of course you are still supporting 8i or 7.3.4.
Hopefully you aren't supporting anything older than 10g, although 11g would be better.
In the 15 years that I have been posting on this site I sometimes notice people updated old threads
and I wonder if they realize that the people who posted to that thread have long ago moved on and
are no longer concerned with the post. As Oracle changes there are new options, new syntax and the
advice from even 4 or 5 years ago doesn't always apply.
If you want to contribute feel free to post to the How To board with any advice that you think people should see.
Thanks for caring and keep posting.
