2. Check the bsu.sh file to examine the java memory size.

more bsu.sh
#!/bin/sh
 JAVA_HOME="/u01/app/oracle/product/middleware/jdk16/jdk"
MEM_ARGS="-Xms256m -Xmx512m"
"$JAVA_HOME/bin/java" ${MEM_ARGS} -jar patch-client.jar $*



3. Solution.
Increase memory in bsu.sh
MEM_ARGS="-Xms2048m -Xmx2048m"


4. Before update.

cat bsu.sh
#!/bin/sh
JAVA_HOME="/u01/app/oracle/product/middleware/jdk16/jdk"
MEM_ARGS="-Xms1024m -Xmx1024m"
"$JAVA_HOME/bin/java" ${MEM_ARGS} -jar patch-client.jar $*

5. After updating bsu.sh 


cat bsu.sh
#!/bin/sh
JAVA_HOME="/u01/app/oracle/product/middleware/jdk16/jdk"
MEM_ARGS="-Xms2048m -Xmx2048m"
"$JAVA_HOME/bin/java" ${MEM_ARGS} -jar patch-client.jar $*

 6. Now execute the script again. it must run without error.

./bsu.sh -view -status=applied -prod_dir=/u01/app/oracle/product/middleware/wlserver_10.3
