You can upgrade the IBM Java Runtime Environment (JRE) that is bundled with Apache
Tomcat in IBM®
Engineering Requirements Management DOORS® - Web
Access
(DWA).
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
DWA.
Procedure
- Download the updated version of the IBM Java JRE from IBM Support.
- Shut down all components of the DWA
installation: the web access broker, interoperation servers, and the Tomcat and Derby servers. For
instructions, see the related links later in this topic.
- Save the current version of the JRE directory as a backup. In the DWA
installation directory, rename the existing JRE directory. The directory path is
dwa_install/os_folder/jre. For example, rename this
directory:
C:\Program Files\IBM\Rational\DOORS Web Access\9.6.0\win32\jre
to:C:\Program Files\IBM\Rational\DOORS Web Access\9.6.0\win32\jre.original
- Extract the new JRE into the installation directory at
dwa_install/os_folder; for example,
C:\Program Files\IBM\Rational\DOORS Web Access\9.6.0\win32
- 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
- Restart DWA and
its components.
