How to List the applied Patches in Weblogic

To List the applied patches in Oracle WebLogic Server, you can use or follow below Methods:

Method-1:

Using the ORACLE WEBLOGIC Admin Console,

1. Log in to the WebLogic Server Administration Console.
2. In the left-hand navigation menu, click on “Domain Structure.”
3. Click on the name of the domain for which you want to list the applied patches.
4. Click on “WebLogic Domain” in the right-hand pane.
5. In the “WebLogic Domain” window, click on the “Configuration” tab.
6. Scroll down to the “Domain Configuration” section, and click on the “General” sub-tab.
7. Look for the “Applied Patches” section. If there are any patches applied to the domain, they will be listed here along with their version numbers and timestamps.

Method-2:

You can use the WebLogic Scripting Tool (WLST) to list the applied patches. Here’s how:

• Open a terminal or command prompt.
• Navigate to the WebLogic Server installation directory.
• Launch the WLST tool by running the following command:

./wlst.sh

• Connect to the WebLogic Server instance by running the following command:

connect('<username>','<password>','t3://<hostname>:<port>')

Replace <username> and <password> with your WebLogic Server credentials, and <hostname> and <port> with the hostname and port number of your WebLogic Server instance.

• Run the following command to list the applied patches:

show_patches()

This will display a list of all the patches applied to the WebLogic Server instance, along with their version numbers and timestamps.

Method-3

For Versions Prior 10.3

1. Go to your MW_HOME/utils/bsu directory
2. 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

1. Goto MW_HOME/OPatch/ directory
2. Run the following command

./opatch lspatches

Sample Output

middlewaredevops@MacBook-Air OPatch % pwd
/Users/middlewaredevops/Documents/opt/Oracle/Middleware/Orcale_Home/OPatch
middlewaredevops@MacBook-Air OPatch % ./opatch lspatches
26295734;One-off
26261906;One-off

OPatch succeeded.

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

Use this trick.

Look for the weblogic.jar file in your filesystem by running below cmd,

find /Users -name “weblogic.jar”

middlewaredevops@MacBook-Air bin % find /Users -name "weblogic.jar"
/Users/middlewaredevops/Documents/opt/Oracle/Middleware/Oracle_Home/wlserver/server/lib/weblogic.jar

You will get the file location like preceding snip, Lets decode it.

/Users/middlewaredevops/Documents/opt/Oracle/Middleware/Oracle_Home/wlserver/server/lib/weblogic.jar

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

therefore /Users/middlewaredevops/Documents/opt/Oracle/Middleware/Oracle_Home/wlserver/ is WL_HOME

MW_HOME = Parent directory of WL_HOME 

therefore /Users/middlewaredevops/Documents/opt/Oracle/Middleware/Orcale_Home/ is my MW_HOME.

Note: You can follow below Guide to Apply Oracle Weblogic & OHS CPU Patches in your infrastructure.
