Solving the error “OUI-25031” during Oracle 10g R2 Grid Control (10.2.0.3) installation

Posted by Kamran Agayev A. on May 17, 2011

Yesterday while installing OEM Grid Control 10gR2 (10.2.3) I got the following error:

As I’ve accustomed to get some errors (or hit a bug) either during Grid Control installation, or configuration, I was calm and after some time found the following documentation which describes the error:

How to Recover From Enterprise Manager Grid Control 10g Base Releases (10.2.0.x.0) Installation Errors after 31-Dec-2010 [ID 1228103.1]

And here’s the explanation 🙂

The Enterprise Manager Grid Control 10g base releases used a fixed end date for the root certificate used to setting up secure communications via the Secure Socket Layer (SSL) protocol. The fixed date used is the 31-Dec-2010 00:00:00 UTC.

The certificate expiration will cause errors to occur if you attempt to install these releases on or after 31-Dec-2010.

Amazing .. Anyway, the solution was adding a Patch and making some configuration changes. Here’re the steps what I’ve done:

Firstly, you need to download and install the Patch 8430622 from metalink

Patch 8430622: LX10201-RECUT(TC3): OMS CONFIG FAILED DUE TO HTTP_SERVER’S MAXIMUM RETRY LIMIT

After downloading the file, copy it to the server, extract it and patch
