[...] 1 – It's easier and there is no shame from that! Installing Oracle on Windows requires no tweaking, optimization or prerequisites. All what you need is to download the binaries and set it up. If for any reason you think that you really need to run Oracle on Linux, then I won't leave you in the dark. Here is an excellent article detailing step by step how to do it if you are a newbie.

[...] 1. Oracle kurulum dökümanı: Oracle`ye yeni başlayanlar için, ekran görüntüleriyle hazırlanmış gayet basit bir döküman. Genel de Oracle kurulum dökümanları biraz karmaşık olur. Bu yüzden hoşuma gitti. Ayrıca kurulum esnasında gerekli komutlar için, makale sahibi 3 adet script yazmış, bunlar da işinizi kolaylaştırıyor. Bence yeni başlayan herkese lazım olabilir, not düşelim.

I’m writing documentation for an upcoming project and it needs to be completely fool proof as always, hence the reason for the documentation. That’s also the reason I did not post it to my site as it is documentation for an unreleased product, the NDA police would kill me!

Weird, that you needed to set them manually though… hmmmm,

Hi Duncan,

Funny you should say that you bothered to document a pretty basic process and a pity you didn’t post it at your site.

I ran the installer also a few times and sometimes the prerequisites just passed and then the install still failed on later. So not sure what is different with your setups.

Also note that it is an install tweaked for minimums -which will run fine on your development laptop without overtaking it – and contains step by step what to do even if you are not very linux savvy.
In addition it contains a lot of details where you can make a mistake configuration wise. Hereby saving you having to rerun the installer which -in the end- can save you a lot of time as it is not the fastest process in the world.

I did the install a couple of times and thought is was pretty basic to be honest. Even when you don’t have all the pre-reqs in place the installer will tell you about this. All the kernel settings can be done from a script that the installer will provide you.

I think it is key to install oracle from the account you created, so logoff. login with the oracle account and install it.

Funny that I documented this complete procedure, as described above, two weeks ago

Thanks Jay for the kind words and the extra notes.

I have been writing code for Oracle, mySQL, postgreSQL and MSSQL for a long time as well now. So that certainly does help a bit when having to setup Oracle on a linux server.

Having said that, I do not consider myself DBA worthy, I know my way around Oracle, but don’t spent enough time on a daily bases with it to know all the ins and outs about the product. I’m just a developer

So your encouragement is truly appreciated.

FWIW I did not have to add the ignoreprereqs parameter, but maybe that’s because Oracle Linux is not technically RHEL either.

As an Oracle Apps DBA for 10+ years, I have to say it’s a very good write-up – nice job!

Couple of minor notes – if running it virtualized I’d recommend adding elevator=noop to the grub.conf file – this will tell the OS to not try and not optimize the I/O with the underlying disks – this becomes especially important when running virtualized connected to a SAN.

Also, Oracle has an oracle-validated RPM that will set all your OS kernel parameters and install any required RPMs you may be missing. The latest version is from March of 09 and sets everything for DBs thru 11gR1 – I’ve been told they’re still (still?!?) working on the 11gR2 version but it’ll do almost everything needed for 11gR2 – if I recall right, a sysctl.conf param or two needs to be modified, but it does make things easier.

Final note – I don’t remember for sure, but in the past the Oracle installer needed to be started with -ignoreprereqs to work on Centos since technically Oracle 11g is only supported on RHEL, not Centos.
