Smart Update Details of WLS Patch Set Update 10.3.6.0.200714

WLS Patch ID - I37G
WLS Patch Number - 31178492

This document includes the following sections:

Section 1: Preparing to Install WLS Patch Set Update 10.3.6.0.200714

- WebLogic Server Patch Set Update (PSU) can be applied on a per-domain basis (or on a more fine-grained basis), Oracle recommends that PSU

be applied on an installation-wide basis. PSU applied to a WebLogic Server installation using this recommended practice affect all domains and

servers sharing that installation.

- Stop all WebLogic server processes

- Remove any previously applied WebLogic Server Patch Set Update and associated overlay patches

- Update Java SE (JDK/JRE):

For users of Oracle JDKs and JVMs, we strongly recommend applying the latest Java 7 Critical Patch Updates (CPUs) as soon as they are released.

Certain WebLogic Server fixes for deserialization vulnerabilities that are provided in WebLogic Server Patch Set Updates (PSUs) depend on

JEP 290 filtering and JEP 290 global scope filtering features provided in July 2018 JDK Updates and later JDK updates.

These WebLogic Server fixes for deserialization vulnerabilities are not effective without these JDK updates, or later JDK updates.

Oracle strongly recommends that you ensure WebLogic Server is running with a supported JDK version, and the following JDK update level at a minimum:

JDK 7 Update 191 (JDK 7u191) or later (for WebLogic Server versions that are supported on JDK 7)

Refer to the following for further information: Doc ID 1506916.1 Obtaining Java SE (JDK/JRE) for Oracle Fusion Middleware Products

https://support.oracle.com/rs?type=doc&id=1506916.1

- If you are running with a security manager and experience java.io.SerializablePermission "serialFilter" permission exceptions, then you will need to

update the weblogic policy file to include the following line:

permission java.io.SerializablePermission "serialFilter";

in the coherence.jar section of the weblogic policy file:

grant codeBase "file:@WL_HOME/../coherence/lib/coherence.jar" {

Section 2: Installing WLS Patch Set Update 10.3.6.0.200714

- Unzip p31178492_1036_Generic.zip to {MW_HOME}/utils/bsu/cache_dir or any local directory

Where, MW_HOME is path of the Oracle Middleware Home.

Note: You must make sure that the target directory for unzip has required write and executable permissions
           for "user" with which the component being patched is installed.

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

- Apply WLS BSU (Smart Update) fix for quicker patch application. This step can be skipped if the fix is already applied.

- Configuring Memory options

   For Microsoft Windows systems
   Edit the bsu.cmd script and change memory options as follows:
   set MEM_ARGS=-Xms1024m -Xmx4096m

   For UNIX Systems
   Edit the bsu.sh script and change memory options as follows:
   MEM_ARGS="-Xms1024m -Xmx4096m"

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

Where, WL_HOME is the path of the WebLogic home,
             PATCH_ID is I37G (Unique identifier for WLS Patch Set Update 10.3.6.0.200714).

Section 4: Post-Installation Instructions

1. Restart all WebLogic servers.
2. The following command is a simple way to verify the successful installation of WebLogic Server PSU patch 10.3.6.0.200714.

$ . $WL_HOME/server/bin/setWLSEnv.sh
$ java weblogic.version

In the following example output, 10.3.6.0.200714 is the installed WebLogic Server PSU.

3. A note about the weblogic.policy file *

   If you are using a Java security manager (for example, you use -Djava.security.manager to start up WebLogic Server),
   you must ensure that the codeBase in your policy file points to the location where the patches are installed.
   The policy file is specified by -Djava.security.policy during server startup.
   By default, this is weblogic.policy file and resides in WL_HOME/server/lib, where WL_HOME is the WebLogic Server installation directory.

   This is an example of what should be added to the weblogic.policy file for the installed patches:

   grant codeBase "file:<path-to-WLS-patch-jars>/patch_wls1036/patch_jars/-" {
        permission java.security.AllPermission;
   };

The default weblogic.policy file is a sample. If you use it, you must modify it. Refer to the following URL for additional information:

  http://download.oracle.com/docs/cd/E17904_01/web.1111/e13711/server_prot.htm

4. A note about FMW 11g installations using PSU patch 10.3.6.0.200714 or later versions.

   You may see this error after starting the Admin Server :

   "Unable to Read Logging Configuration from File 'logging.xml' exception: oracle.core.ojdl.logging.LoggingConfigurationException:     ODL-52050"
    or
   <BEA-149231> <Unable to set the activation state to true for the application 'SHAREDSERVICES [Version=11.1.2.0]'.

   Please consult this KM Note to evaluate your situation:
   https://support.oracle.com/rs?type=doc&id=2604499.1

5. If your deployed application uses Java deserialization you may need to customize the WebLogic JEP 290 Default Filter.

   For further information, refer to the "Restrict incoming serialized Java objects." line in the Securing Network Connections table at
   https://docs.oracle.com/middleware/11119/wls/LOCKD/GUID-E5E57EA2-90AC-49E5-AF35-E217B8980BDC.htm#GUID-9A5D9EE1-BE59-475C-BF61-19D4EFC6EDFF

Section 5: Uninstalling WLS Patch Set Update 10.3.6.0.200714

- Navigate to the {MW_HOME}/utils/bsu directory.
- Execute bsu.sh -remove -patchlist={PATCH_ID} -prod_dir={MW_HOME}/{WL_HOME}
