Install Oracle 11gR2 on RHEL8

  • A+

First of all, I do not recommend to install Oracle 11gR2 on RHEL8, especially in the production environments.

While if you have to do such installation for test or data migration, then you could refer this post.

Last year I saw a task on Upwork to do such installation, and at the beginning I thought such thing would not be so tough and I should be able to finish it soon. To confirm I could finish it I installed RHEL8 on my VM and tried to install Oracle 11gR2 no it. I encountered several different errors and even I tried to downgrade the GCC version. I could not remember how many days I spent on it before I completed it finally.

I forgot to write down all the issues while I did upgrade my Oracle installation preparing script to support RHEL8.

In last month, I found another similar task also on Upwork and I did the same test again, and this time I finished it quite smoothly. While I still could not earn the fee as the owner did not award this task to me. :)

It is better as now I could share this experience without much concern.

Three key things should be done here:

1. Install the required packages.

2. Add the needed library link

3. Downgrade the libaio* to RHEL7 version

Then you can install Oracle 11gR2 on RHEL8 just like on RHEL7!
