Patch Installation in Weblogic Server


  1. Download the patch from My Oracle Support (MOS). For more details, please refer to Master Note: How to Locate and Download Patches for WebLogic Server Using My Oracle Support Note 1302053.1.
  2. Extract the contents from the zip file: you will have a jar file and patch-catalog.xml. A readme file may also be included.
  3. Copy the files (for example, E5W8.jar and WGQJ.jar) and the patch-catalog.xml from the zip file to the target machine. You do not need the readme file. Copy the files to the appropriate cache_dir directory for the target system: for example, on Windows,

%MIDDLEWARE_HOME%\utils\bsu\cache_dir, or on UNIX, $MIDDLEWARE_HOME/utils/bsu/cache_dir.

NOTE: Always copy the patch-catalog.xml file from the downloaded patch. Each time you apply a patch, you will need the updated patch-catalog.xml file.

  1. Run Smart Update and apply the patches and/or patch sets to the target system. This can be done using the Smart Update GUI or the command-line interface (see


  1. Do not delete any patch files in cache dir, and never rename any patch_catalog files.
  • This is the syntax for the command to view the downloaded patches as below:
./ -prod_dir=<weblogic_home> -patch_download_dir=<download dir of patch> -status=downloaded -view -verbose

This is the syntax for the command to install a patch:

./ -prod_dir=<weblogic_home> -patchlist=<patchID> -verbose -install

For example:

./ -prod_dir=/opt/bea/weblogic92 -patchlist=E5W8 -verbose -install
./ -prod_dir=/opt/bea/weblogic92 -patchlist=WGQJ -verbose -install


This is the syntax for the command to check if the patch is installed:

./ -prod_dir=<weblogic_home> -patch_download_dir=<download dir of patch> -status=applied -verbose -view

For example:

./ -prod_dir=/opt/bea/weblogic92 -status=applied -verbose -view

1. Shutdown all servers (admin and managed).
