Upgrading the JRE for Rational DOORS Web Access

You can upgrade the IBM Java Runtime Environment (JRE) that is bundled with Apache Tomcat in IBM® Rational® DOORS® Web Access. JRE updates are sometimes required to fix security vulnerabilities.

Before you begin

To obtain the updated version of the IBM Java JRE, contact IBM Support. Support can help identify the latest JRE that is compatible with your operating system and platform. Publicly available versions of the Oracle JRE are not supported with Rational DOORS Web Access.

Procedure

  1. Download the updated version of the IBM Java JRE from IBM Support.
  2. Shut down all components of the Rational DOORS Web Access installation: the web access broker, interoperation servers, and the Tomcat and Derby servers. For instructions, see the related links later in this topic.
  3. Save the current version of the JRE directory as a backup. In the Rational DOORS Web Access installation directory, rename the existing JRE directory. The directory path is dwa_install/os_folder/jre. For example, rename this directory:
    C:\Program Files (x86)\IBM\Rational\DOORS Web Access\9.6.0\win32\jre
    to:
    C:\Program Files (x86)\IBM\Rational\DOORS Web Access\9.6.0\win32\jre.original
  4. Extract the new JRE into the installation directory at dwa_install/os_folder; for example, C:\Program Files (x86)\IBM\Rational\DOORS Web Access\9.6.0\win32
  5. Delete the Apache Tomcat temporary files that are in these directories:
    • dwa_install/os_folder/server/temp
    • dwa_install/os_folder/server/work/Catalina/localhost
  6. Restart Rational DOORS Web Access and its components.
