How To Apply weblogic PSU Patch

Env Details:

OS= Windows Server 2012 R12 64bit

#Middleware Home

MW_HOME= D:\Oracle\Middleware

Step 1.  

In this example we will be installing WLS PSU 10.3.6.0.211019(p33172858_1036_Generic.zip)

So download the patch from support.oracle.com

P.S. Following are the generic steps for installing a WLS Psu patch. But its always recommended to go through the readme file first and act accordingly.

Step 2.

Shutdown weblogic services in following order.

1.       Stop opmn process

2.       Stop WLS_REPORTS services

3.       Stop WLS_FORMS services

4.       Stop Weblogic Admin server

 

Step 3.

Remove any previously applied WebLogic Server Patch Set Update and associated overlay patches

In this example, we didn’t have any previously applied wls PSU installed.

To get information about list of patches installed run following command.

Cd D:\Oracle\Middleware\utils\bsu D:\Oracle\Middleware\utils\bsu>bsu.cmd -report Patch Report ============   Report Info     Report Options       bea_home.................. ### OPTION NOT SET       product_mask.............. ### OPTION NOT SET       release_mask.............. ### OPTION NOT SET       profile_mask.............. ### OPTION NOT SET       patch_id_mask............. ### OPTION NOT SET     Report Messages   BEA Home..................

We faced error while generating above report. Error was like "java.lang.OutOfMemoryError: Java heap space" 

 

Solution :

This solution is for Windows 64bit OS.

Go to $MW_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="-Xms4096m –Xmx4096m"

 

 

Step 4.

Apply WLS BSU (Smart Update) fix for quicker patch application. This step can be skipped if the fix is already applied.

Apply patch Patch 12426828 SMARTUPDATE 3.3 INSTALLER PLACEHOLDER 

Check readme file for patch apply instructions.

To check bsu version

%MW_HOME%\utils\bsu\bsu.cmd -version (for Windows)
$MW_HOME/utils/bsu/bsu.sh -version (for Unix/Linux)

 

Step 5.

Create Cache_dir

Create Directory cache_dir inside $MW_HOME/utils/bsu

Copy The Downloaded Patch To $MW_HOME/utils/bsu/cache_dir 

And unzip it inside cache_Dir directory.

 

 

Step 6. 

Set The Environment Using setWLSEnv.sh 

cd D:\Oracle\Middleware\wlserver_10.3\server\bin setWLSEnv.cmd

 

Step 7. 

Run The Patch Install Command Using bsu.cmd

Syntax:- - Execute bsu.cmd -install -patch_download_dir={MW_HOME}/utils/bsu/cache_dir -patchlist={PATCH_ID} -prod_dir={MW_HOME}/{WL_HOME}

bsu.cmd -install -patch_download_dir=D:\Oracle\Middleware\utils\bsu\cache_dir -patchlist=21Y4 -prod_dir=D:\Oracle\Middleware\wlserver_10.3 -install -log=patch_apply.log -log_priority=trace

 

This entire process takes sometime to complete.

 

Step 8.

Verifying the Patch

cd $MW_HOME/utils/bsu  bsu.cmd -report -bea_home=D:\Oracle\Middleware -output_file=bsureprot.log

 

Also, this can be verified from weblogic console.

Domain Structure -> Servers->Click on Adminserver ->Monitoring ->General

This page will show you weblogic version.

 

Step 9.

Start all weblogic services

1.       Start  Weblogic Admin server

2.       Start WLS_FORMS services

3.       Start WLS_REPORTS services

4.       Start OPMN services

If you need to remove patchset:-

bsu.cmd -remove -patchlist=21Y4 -prod_dir=D:\Oracle\Middleware\wlserver_10.3
