Here in this post, we will see how to check patches applied in weblogic in 10.3.6 version, 12c (12.1.1 and 12.1.2 and later ).
How to check patches applied in weblogic in the 10.3.6 version and up to 12.1.1
- Weblogic Smart Update utility (bsu) is used to apply patches in the 10.3.6 and 12.1.1 versions of weblogic.
- Weblogic Smart Update utility (bsu) lies in $MW_HOME/utils/bsu/
- BSU Utility stands for BEA Smart Update utility
Now how to check patches applied in weblogic in 10.3.6
For Unix
cd $MW_HOME/utils/bsu/ bsu.sh -prod_dir=$MW_HOME\wlserver_10.3 -status=applied -verbose -view
For Windows
bsu.cmd -prod_dir=$MW_HOME\wlserver_10.3 -status=applied -verbose -view
Another simple way to determine the application of WebLogic Server PSU.
For Unix
$ . $WL_HOME/server/bin/setWLSEnv.sh $ java weblogic.version
For Windows
$WL_HOME/server/bin/setWLSEnv.cmd java weblogic.version
In the following example output, 10.3.6.0.190416 is the installed WebLogic Server PSU.
WebLogic Server 10.3.6.0.190416 PSU Patch for BUG29204678
java weblogic.version -verbose can give more output
If you receive the below error while checking with the BSU utility
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2521) at java.lang.Class.getMethod0(Class.java:2764)
The following steps can be used
Increase the heap size to allow more memory and prevent an eventual “java.lang.OutOfMemoryError: GC overhead limit exceeded” error:
Go to $WL_HOME/utils/bsu Prepare to edit the bsu.sh (for UNIX) or bsu.cmd (for Windows) Find the MEM_ARGS setting, e.g., the default as MEM_ARGS="-Xms256m -Xmx512m" Increase these values to a higher setting, e.g., MEM_ARGS="-Xms1024m -Xmx1024m"
Ensure MEM_ARGS are used in the bsu script for the patch-client.jar to resolve “java.lang.OutOfMemoryError: Java heap space” error:
Look for the line:
"$JAVA_HOME/bin/java" -jar patch-client.jar $*
Change to the following to ensure the MEM_ARGS are passed:
"$JAVA_HOME/bin/java" ${MEM_ARGS} -jar patch-client.jar $*
How to check patches applied in weblogic in Weblogic 12.1.2 and later
BSU Utility is deprecated in 12.1.2. We use opatch to patch the weblogic installation
On Unix:
cd $MW_HOME/OPatch
./opatch lsinventory
or
./opatch lspatches
On Windows:
Please make sure to open cmd with Administrative options
cd %MW_HOME%/OPatch opatch lsinventory
Apart from checking from these commands given above, the weblogic version and patches applied can be found in the admin console startup log also. So you just need to start the Administrative server and check its log to see the version
Hope you like the post and that it helps you check patches applied
