Today I’d like to discuss a very important topic which is patch management in an Oracle IDM/IAM deployment. Patching seems like a pretty basic topic. It is often taken for granted. However, experience has shown me that patching is a frequent source of confusion for many enterprise software customers including those deploying the Oracle Identity Management stack.
So, I thought I’d address some common questions / topics related to patching so that people have a better understanding of what patches to apply to their environments and when to apply them.
This post is a part of both the OAM 11g academy and OIM 11g academy series.

Tell what patches are installed in your Oracle IAM 11g deployments using OPatch
People often want to know how they can tell what versions (including patches) of software they are running in their different environments. Fortunately, there is a simple standard way to get this information for all software that uses the Oracle Universal Installer. The method I speak of uses the OPatch utility that is standard for all Oracle products that use the universal installer. This includes most, if not all of Fusion Middleware 11g and all of the 11g Identity Management packages.
OPatch is the utility used to patch Oracle products that utilize the Oracle Universal Installer. It is included in most product/package installs under that package’s ORACLE_HOME/OPatch.
Now, keep in mind that when you execute OPatch it will operate on the ORACLE_HOME that is set in the environment. So, if you are operating in an environment where you have multiple products/packages installed under one Fusion Middleware Home (FMW_HOME) you want to make sure that you have an ORACLE_HOME environment variable pointed to the product/package you are interested in patching or analyzing.
To get information on the version and patch levels of your Oracle product/packages run ‘opatch lsinventory’. Again, make sure that ORACLE_HOME is set to the product/package that you want the information for. If it is not set, then OPatch picks some default ORACLE_HOME from your FMW_HOME in a manor I have yet to figure out.
You can also use OPatch to tell you all the ORACLE_HOMEs that exist under your FMW_HOME by running ‘opatch lsinventory -all’.
The documentation for OPatch can be found in the Oracle Universal Installer and OPatch User Guide
