How to apply weblogic patch in R12.2

Copy the patches and move to the below location :

$FMW_Home/utils/bsu/cache_dir

Unzip patches in above location. When you unzip the patch you will get the jar file named with 4 character. Ex : B47X. Use these jar files while applying patch. 

Command to apply weblogic patch in R12.2 :

bash-3.2$ bsu.sh -install -patch_download_dir=$FMW_Home/utils/bsu/cache_dir -patchlist=B47X -prod_dir=$FMW_HOME/wlserver_10.3

Checking for conflicts................

Conflict(s) detected - resolve conflict condition and execute patch installation again

Conflict condition details follow:

Patch B47X is mutually exclusive and cannot coexist with patch(es): YIJF,LL4G,D33T,VFS8,Y5AP

Command to rollback the conflicts :

bsu.sh -remove -patchlist=YIJF -prod_dir=$FMW_HOME/wlserver_10.3

bsu.sh -remove -patchlist=LL4G -prod_dir=$FMW_HOME/wlserver_10.3

bsu.sh -remove -patchlist=D33T -prod_dir=$FMW_HOME/wlserver_10.3

bsu.sh -remove -patchlist=VFS8 -prod_dir=$FMW_HOME/wlserver_10.3

bsu.sh -remove -patchlist=Y5AP -prod_dir=$FMW_HOME/wlserver_10.3

Fix :

Update MEM_ARGS parameter in bsu.sh file after taking backup under $FMW_HOME/utils/bsu/

#!/bin/sh

JAVA_HOME="/a01/appsclone/CLONE/fs2/EBSapps/comn/util/jdk"

MEM_ARGS="-Xms2048m -Xmx2048m -XX:+UseParallelGC"

"$JAVA_HOME/bin/java" ${MEM_ARGS} -jar patch-client.jar $*
