I decided to build my first sand box ever. I always wanted one, but there was no time or reason until now. Fortunately, hardware is ridiculously cheap these days compared to the past, so you can actually run full-blown Oracle Applications on your home PC without compromises.

I built a Dual Core box with 8G of RAM for an install of E-Business Suite R12. For OS I chose Oracle EL5U2, mainly because I’m used to the RH/OEL clones, and also because I expected it to be less painful than other distributions.

I started slowly, as time allowed, spending some time chasing various libraries and packages on the Net. Eventually it took me a week to realize how tedious it is to go the manual way. I got so frustrated by the dependencies that I gave up and purchased access to the ULN network.

Just to illustrate the type of struggle I went through, I found four distinct lists of required packages for 10g installation (in Oracle documentation and metalink combined). I’d recommend Note 421308.1 - Requirements For Installing Oracle10gR2 On RHEL/OEL 5 (x86_64), which summarizes the database part in a neat way. I also encourage you not to underestimate requirements of related Note 376183.1 - Defining a “default RPMs” installation of the RHEL OS.

Nevertheless, it’s just way more easy to use the oracle-validated package, which will download all dependencies for you. Well, almost all.

The next step was to prepare the machine. The only tricky part (from the DBA point of view) is to setup a DNS server, but even that went well. There are plenty of nice howtos on the web — search for keyword “rndc”.

Once I had all the required packages installed, users created, kernel parameters set, domain name resolution working, and Xvnc started, it was time to call a wizard.

I recently installed Oracle DB 10.2.0.1 RAC (two nodes) on Oracle Enterprise Linux x86_64 and faced three issues. Since I had to dig out at several places, I thought it might benefit others to have my notes all here.

Facts

1. OS : OEL 4 — 2.6.9-67.0.0.0.1.ELsmp #1 SMP Sun
2. 2 Node RAC Install
3. Clusterware / RDBMS - 10.2.0.1

Issue 1: Error while loading shared libraries: libstdc++.so.5 during root.sh run on first node.

After weeks of not having the time I wanted for this, it’s finally done! Today, I installed RAC on Oracle Enterprise Linux 5 (OEL5), and I can tell you that there’s nothing exceptional about the process.

The only trouble I encountered had nothing directly to do with the installation. In order for the device rights to be assigned when RHEL5 or OEL5 start up, you have to create a file in /etc/udev/rules.d, but I have already spoken about that in my last post on the subject of raw devices.

Besides that, it’s all quite simple once 10g’s prerequisites are met. After an hour and a half, it was all wrapped up, at least for two nodes. I didn’t see anything revolutionary differences, but nonetheless there are some points worth mentioning.
