QUESTIONS AND ANSWERS

On Weblogic Server 8.1, patches can applied using the following steps:

1. Extract the jar file from the patch, which will be in the format CRxxxxxx_810sp6.jar OR bugxxxxxx_810sp6.jar.
2. Save the jar file you extracted to the file system and note its location.
3. Open the start script for the server (on Windows, startWebLogic.cmd; on UNIX, startWebLogic.sh).
4. Locate the CLASSPATH declaration, which looks something like this:
   
   CLASSPATH=$WL_HOME:$WL_HOME/lib/weblogic_sp.jar:$WL_HOME/lib/weblogic.jar
   (UNIX) OR
   
   set CLASSPATH=%WEBLOGIC_CLASSPATH%;%POINTBASE_CLASSPATH%;%JAVA_HOME%\jre\lib\rt.jar;%WL_HOME%\server\lib\webservices.jar;%CLASSPATH%
   (Windows).
5. Edit the CLASSPATH declaration by adding the fully qualified patch file name to the front of the declaration. For example, in Windows:
   
   1. Save the patch file, CRxxxxxx_810sp6.jar, to C:\bea\weblogic81\patches\.
   2. Then edit the start script as follows:
      
      set PATCH_PATH=C:\bea\weblogic81\patches\CRxxxxxx_810sp6.jar
      set CLASSPATH=%PATCH_PATH%;%WEBLOGIC_CLASSPATH%;%POINTBASE_CLASSPATH%;%JAVA_HOME%\jre\lib\rt.jar;%WL_HOME%\server\lib\webservices.jar;%CLASSPATH%
   In UNIX, use UNIX syntax and delimiters:
   
   1. Save the patch file, CRxxxxxx_810sp6.jar, to /opt/bea/weblogic81/patches/.
   2. Then edit the start script as follows:
      
      PATCH_PATH=/opt/bea/weblogic81/patches/CRxxxxxx_810sp6.jar
      CLASSPATH=$PATCH_PATH:$WL_HOME:$WL_HOME/lib/weblogic_sp.jar:$WL_HOME/lib/weblogic.jar
6. Repeat the above steps for each managed server where the patch should be applied.
7. Restart the server.
