How to list the applied Patches in Weblogic:

To find List the applied patches in weblogic,do the following.

For Versions Prior 10.3:

Go to your MW_HOME/utils/bsu directory
Run the following command

./bsu.sh -report

Note* If you get any error like “unable to access patch-client.jar” – Execute the setWLSEnv.sh from WL_HOME/server/bin script and retry

For weblogic 12c and above:

Goto MW_HOME/OPatch/ directory
Run the following command
./opatch lspatches

If you are not aware of what is your MW_HOME and what is your WL_HOME.

Look for the weblogic.jar file in your filesystem

$ find /apps -name "weblogic.jar"
/apps/oracle-weblogic/wls12213/wlserver/server/lib/weblogic.jar

WL_HOME = Parent directory of server/lib/weblogic.jar 

therefore /apps/oracle-weblogic/wls12213/wlserver/ is WL_HOME

MW_HOME = Parent directory of WL_HOME

therefore /apps/oracle-weblogic/wls12213 is my MW_HOME
