Upgrade of Java 2 Connector (J2C) Resource Adapter Archive (RAR) in WebSphere Application Server
 Technote (troubleshooting)
 
Problem(Abstract)
To upgrade a RAR file for a Connector, a reconfiguration is the best option. The problems that may occur when the simple replacement is done are explained.
 
Resolving the problem
The recommended way to upgrade a RAR file is to uninstall the existing RAR along with its configuration and to install the new RAR and rebuild the configuration.

It may be possible to replace the RAR file, but problems can occur if there are changes in the custom properties for the Connector or if native code comes with the RAR.

To replace the RAR file:

  1. Create a new directory and unzip the rar into this directory.
  2. Edit the archivePath property under Resources->Resource Adapters->[RA Name] to the created directory.
  3. Restart the application server.

If problems occur, then there are changes in the configuration that require a full reinstall.


In the case that the RAR contains native libraries, if the libraries are at the top level of the resource adapter .rar file, then they were handled by the install process (copied to %WAS_HOME%\installedConnectors\ConnectorName):

  • Save the old version
  • Copy the new version into the same directory
If they are in sub-directories (separated by platform), then the RAR file must contain a readme file that describes how to handle the native libraries.
