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.
