Upgrading Oracle WebLogic Server

As part of patching an Oracle BI Entreprise Edition (OBIEE) installation I had to patch an Oracle WebLogic Server (WLS) from version 103.5 to 10.3.6. This post describes the process of doing this update.

Upgrading WLS from 10.3.5 to 10.3.6

Patching a WebLogic server is a fairly easy process. And can be done in the following steps

Download the software

You can download the WebLogic Server software from Oracle Support. It isn't easy but it has to be done.
Once you have logged in to Oracle Support do the following:
  1. Click on the "Patches & Updates" tab
  2. In the "Patch Search" box select the following
    1. Product - Oracle WebLogic Server
    2. Release - 10.3.6 (or whatever release you are looking for)
    3. Platform - Whatever platform you are looking for
    4. Description - upgrade
    5. Click Search
  3. Click the Patch Name/Number
  4. Click the Download button.
This should get you the upgrade installer you need.

Backup your software and domain folders

Just to be on the safe side it is a good idea to backup your software and domain folders. The easiest way to do that is to Zip the folders and copy the zip files to a safe place.

Run the installer

To run the installer simply run the downloaded file. On 64 bit architectures that is most like running:

java -jar wls1036_upgrade_installer.jar

Once the installer is ready it is simply going through the install wizard.

The next part is to patch the OBIEE software with the latest version.
