Paweł Barut said...Hello Tim,
You should add that after setting
reboot of linux box is needed to take effect.
Tim... said...I've added the extra comment as advised, but if the document is followed, this step should really be unnecessary as SELinux should be switched off as part of the OS installation.
thanks, this article helped me a lot, since I'm quite new to Linux!
Albaraha said...CentOS 5 block size defaults to 4k while the non-custom oracle templates have datafiles with 8k block size.
This need to be mentioned in the guide.
Anyhow, this howto is great.
I would almost always expect the Oracle block size to be bigger than the OS block size. Provided it is a multiple of the OS block size it is not really important.
All this means is the 2K Oracle block size is unavailable on this OS, as the Oracle block size should always be a multiple of the OS block size.
Having an 8K Oracle block size sounds fine on this OS.
Albaraha said...I got a problem when I chose the general template in DBCA telling me an error about the block size. So I re-created the database with the custom template and chose the block size to be 4K, which hence solved the problem.
I ended up without any line that looks like
in my /etc/oratab.
Is DB11G the default for Oracle's own database?
I added "DB11G:/u01/app/oracle/product/11.1.0/db_1:Y" to oratab and ran dbstart but Oracle did not start. Here's what I saw in the startup.log:
/u01/app/oracle/product/11.1.0/db_1/bin/dbstart: Starting up database "DB11G"

logger: No init file found for Database instance "DB11G".
logger: Error: Database instance "DB11G" NOT started.

however, I found them on disk 3.
The location of the packages may vary depending on the respin (update) of the OS. The important thing is you get them installed. :)
Wade said...Everything is fine, but the hostname being "oel45.localdomain" caused a lot of 'not found' problems, especially when having to reinstall because of other issues. Changing it to "localhost" (and reinstalling) fixed that.
Certainly, the ORACLE_HOSTNAME should be set to your machine name. Mine was called OEL45.localdomain, hence my setting. :)

Senthilkumar said...Hi Tim!!

sk said...hi Tim,
Everything works well.. but after restart my system oracle didn't work.. it shows ORA-12535 Request Timed Out.. how can fix this? pls hlp..
My OS is RHEL 4.0
Rojah said...Thanks Tim. I have used you as a resource a few times. I have just installed 11g on CentOS 5.6 (within VMWare). Runs fine. Great page.
Lesson Learned: Do not try to install $ORACLE_HOME to symmlink -- doesn't work. Also delete /etc/ora* entries when reinstalling else it looks for that same link.
Again, Thank you.
