Applying WebLogic PSU and patch conflicts!

Applying latest PSU Patch Set Update﴿ for latest bug fixes and security vulnerabilities,
(PSU October 2016﴿

Patch ID: K25M
Patch No: 23743997

To find the relevant patch number.:
1. Checked the Critical Patch Updates, Security Alerts and Third Party Bulletin
3. Looked for “Oracle WebLogic Server” and clicked on Fusion Middleware next to the product
4. Searched for “WebLogic Server”.

Then download the patch from MOS

Also refer following MOS note.

Oracle E-Business Suite Release 12 Critical Patch Update Knowledge Document (October 2016) (Doc ID 2181748.1)

Set your environment:


 cd wlserver_10.3/server/bin

.  ./

Verify the patch applied or not -prod_dir=$FMW_HOME/wlserver_10.3 -status=applied -verbose -view | grep -i K25M

Unzip the patch to the cache_dir directory:
cd $FMW_HOME/utils/bsu/cache_dir

cp /oracle/software/ $FMW_HOME/utils/bsu/cache_dir

Stop all WebLogic servers

Install the patch using the Smart Update command utility:
cd $FMW_HOME/utils/bsu

./ install patch_download_dir=$FMW_HOME/utils/bsu/cache_dir patchlist=K25M prod_dir=$FMW_HOME/wlserver_10.3

Patch Conflicts detected

Conflict condition details follow: 

Patch K25M is mutually exclusive and cannot coexist with patch(es): HSZB,Z62H,5C71,7Z9S,DEM4

This means that the new PSU patch is conflicting with the other patches listed above, so I have 3 options here:
1. Forget about the latest PSU patch and leave– not recommended.
2. Request an “overlay” patch from Oracle Support which effectively merges all of the patches if some patches listed above aren’t included
in the new PSU﴿.
3. If the new PSU contains all of the above patches, remove them first, then apply the new PSU.

Capture patches installed

cd $FMW_HOME/utils/bsu

/ -prod_dir=$FMW_Home/wlserver_10.3 -status=applied -view -verbose > /tmp/bsu_patches_installed.log

Remove patches
cd $ FMW_Home/utils/bsu

The below patches are Oracle WebLogic Sever overlay patch for PSU We  need to remove these following patches in order to apply the latest PSU.


./ -prod_dir= $FMW_Home /wlserver_10.3  -patchlist= <Patch ID> -verbose -remove

Now  Install  the patch.

cd $ FMW_Home/utils/bsu -install -patch_download_dir=$FMW_HOME/utils/bsu/cache_dir  -patchlist=K25M -prod_dir=$WLS_HOME

cd  $FMW_HOME/wlserver_10.3/server/bin
.  ./

 java weblogic.version|grep PSU
