With Software patching being one of the more work intensive and error prone tasks in your daily business, it is nice to see that there are people constantly working to make this easier, more reliable and less demanding.
OBIEE Development has taken the time to lay out steps to automate the patching process of OBIEE by using Deployment Procedures (DP) that are already available in Enterprise Manager 12c.
A Deployment Procedure (DP) is a sequence of steps and phases, where each phase can contain sequence of steps. The steps can be scripts or commands to be run on any BI host where patch has to be applied. The DP once created can be used to:
- Apply a patch on multiple BI environments.
- Apply multiple patches if the steps to patch are the same.
- Apply multiple patches having different patching instructions by customizing the DP (adding new steps and enabling/disabling certain steps).
The complete article including detailed explanations, steps and screenshots can be found in:

Apart from the obvious work to create this detailed guide and the simplicity of the idea to use what already exists, what I personally like about this is that these Deployment Procedures carry the potential to work for other software that runs on a Weblogic Server just as well.
- They are pointed at any Weblogic Server that are managed by Enterprise Manager 12c
- They call opatch with a user defined set of instructions
so unless we hear different, it is fairly safe to assume that the same technique can be applied to any other Weblogic based Application that uses opatch for patching.
To prevent anyone from thinking that I am are jumping to conclusions here: there is a KM note indicating this:
Master Index for Provisioning and Patching through Deployment Procedures (a Generic Note specific to a Target Type) (Doc ID 1305014.1)
definitely one to keep bookmarked to ease the troubleshooting of DPs:
Tips and Tricks on Debugging Deployment Procedures (Doc ID 463355.1)
And finally the detailed steps to use Deployment Procedures in the Oracle Enterprise Manager Lifecycle Management Administrator's Guide ( Chapter 42 "Customizing Deployment Procedures") along with the instructions how to create them in the first place ( Chapter 41.6 "Creating, Saving, and Launching User Defined Deployment Procedure (UDDP)")
