****ching filesystems

[reeshe]

Hi Friends,

OS RHEL 4.6
DB ORACLE 10g R2

I have installed oracle 10g home (binaries) on /u01
Since the disk which this file system is placed on is showing some failures
or seem to retire, I mounted another DISK and create /u02 on it
and copied all the contents of /u01.
My plan is to switch the two files systems.

My question is what kind of COPY command will I use so that I will completely mirror everything to /u02. And when I switched filesystem names, My oracle db will start normally.

Thanks a lot

ps > the title is supposedly "switching" not "****ching"

-p and -R probably

Use the following commands

cd /u01
cp -rp * /u02

Thanks Davey & Sunil

So it will take care also the hand & soft links, no need to relink oracle executables then?

It's not that simple, check out 'Cloning an Oracle Home' in the fine Oracle manual.

[davey23uk]

this isnt cloning, it will be the same one eventually

this isnt cloning, it will be the same one eventually

It is, when you change the path of Oracle home.

I am not changing path or anything logical dear
Its the physical disk I am chaging.

Its like this:

I have a hard disks /dev/sa1 mounted on /u01 where oracle binaries are installed.

Since this hard disks shows some errors ( coz its 4 yo) I want to act proactively.
I mounted new hard disk /dev/sb1 mounted on /u02
Then copied everything on /u01 to /u02
Then unmount /u01 and /u02
Then mount /dev/sb1 to /u01


Note>>> nothing was changed in the path
Is this ok? Or I need to relink

Thanks

no relinking necessary

You could re-link as a "health check".
