CentOS

we are very happy at last to have centos 6 ,
I have a question , Are we able to instal oracle 10g R2 on the new centos 6 ?
anyone did that successfully ? , or anyone have a guide for that ?

Thanks

Last I remember seeing [url=http://www.oracle.com/technetwork/database/database10g/documentation/database10g-096307.html]Oracle[/url] was not even supporting their own EL6 clone, nor RHEL6, for Oracle databases.

That was me, that was in February, if I remember correctly. I suspect that's changed (but don't know--we're running it on OLE 5.x)

The best thing to do is have your DB people open a support ticket and find out if OLE 6.x is a supported 10G platform. If it is, then CentOS 6.x should certainly work. (Even at the time we checked, they didn't say it wouldn't work, they just said it was unsupported.)

Another tip--if the hardware vendor (Dell in our case) supports RH, they'll often be quite helpful. It seems as if vendors too, don't want to send you to Oracle support--though in the one case I did have to deal with Oracle's Linux support, the person was knowledgeable and helpful.

I found a link here that may be useful

https://www.oratoolkit.ch/knowledge/howto/installation/eeSrv-10g-R2-on-RHEL-6.0-x86_64.php

but this is experimental .

I tried to install it using the oratoolkit link above ,
it was installed successfully , but when I restarted the machine it can not boot anymore ,
it starts ok and give me the graphical loader that contain the centos logo and stop at that ,
any help please to get my machine work again .

Boot to runlevel 3, AKA text mode, by interrupting GRUB by typing a character such as "space" then appending to the kernel line by typing "a", backspacing through "rhgb quiet" and appending " 3". That should give you more verbose output and perhaps let you log in as root. If that fails you can try runlevel 1 (single user) instead of 3.

If all of the above fails then booting is rescue mode from installation media is the next thing I'd try.
