Weblogic-- a note on applying PSU updates

Here is a note that is created by my collegue Hulya Yılmaz, while patching a 10.3.6 Weblogic instance with the WLS Patch Set Update 13.

The master note used in this upgrade was:
Master Note on WebLogic Server Patch Set Updates (PSUs)(Doc ID 1470197.1)

The Middleware and Weblogic Home were:


The steps :

1. Stop all WebLogic servers

2. unzip to {MW_HOME}/utils/bsu/cache_dir

3. . $WL_HOME/server/bin/

4. Navigate to the {MW_HOME}/utils/bsu directory

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

bash-3.2$ -install -patch_download_dir=/data/oracledev/Middleware/utils/bsu/cache_dir -patchlist=S8C2 - prod_dir=/data/oracledev/Middleware/wlserver_10.3 -log=/tmp/bsu.log
Checking for conflicts.......
No conflict(s) detected Installing Patch ID: S8C2..
Result: Success

Note: if bsu will hand, then we increase the heapsize by following the note below.

WebLogic Server: Smart Update Throwing OutOfMemoryError (Doc ID 1154089.1)

6. Verify psu:

bash-3.2$ java weblogic.version
WebLogic Server PSU Patch for BUG21984589 TUE NOV 26 15:54:42 IST 2015 WebLogic Server Tue Nov 15 08:52:36 PST 2011 1441050

7. Restart all WebLogic Servers


  1. An older patch "" says to set
    MEM_ARGS="-Xms512m -Xmx1024m".
    We ran into "Exception in thread "Main Thread" java.lang.OutOfMemoryError" when patching an old test server which never had 22248372 installed.

  2. Thanks for pointing this out, Jerry.
    It is a known Issue for weblogic patches, documented in other documents like Oracle E-Business Suite 12.2 Patching Technology Components Guide (Doc ID 1355068.1), as well.
