Good day!

Just to validate from you experts if in case I change the destination file of my archive logs, does it require a restart of the database?

Thank you in advance.

What prevents you from testing it yourself?

Sir, I'm referring to a production server.

I just read from some forums that this does not require a restart.

Thanks.

>Sir, I'm referring to a production server.
Surely you have a TEST DB upon which you can run a simple test

It would be helpful if you followed Posting Guidelines - http://www.orafaq.com/forum/t/88153/0/

I'm sorry to tell you Sir in our case, we don't have yet.
We had for 9i, 8i & 7... I would not post it anyway,
if we can test it.

This production server was once maintained by our outsourcer.
It was turned-over to us 2 years ago where the setting of
it's archive log is via FLASH_RECOVERY_AREA.

Thanks.

Does this mean that no changes have been made on this system since then?

Unfortunately yes. It was not properly turned-over to
us, and no good documentations at all.

Please give me the answer for my post, does it require a restart or not.

Thank you.

I understand why you would like some re-assurance before attempting to make untested changes on a production system. Do not worry: you can issue the appropriate ALTER SYSTEM commands while the system is running.

But the commands may not work. I do not have a 10g database, so I can't test, but when doing this with 11g recently I did find some problems with Standard Edition. I can't remember the details, but I think that if you are using Enterprise Edition, you can change from the FRA to log_archive_Dest_n no problem; but SE didn't let me change from FRA to log_archive_dest and log_archive_duplex_dest.

Try it - you will not crash the database.

Reym21,

You doesnt need a restart for changing the destination file of your archive logs.
You can do it easily with "alter system set" command.
