9.6.0 - 9.6.0.77.0.85
9.6.1 - 9.6.1.107.0.85
For versions of Rational DOORS Web Access that are earlier than version 9.5.1.x, IBM recommends upgrading to a fixed, supported version/release/platform of the product.

Procedure:

  1. Download the required version of Apache Tomcat or later core zip file from the Apache or Tomcat 7 Archive download site. For example:
    apache-tomcat-7.0.85-windows-x64.zip
    apache-tomcat-7.0.85-windows-x86.zip
    apache-tomcat-7.0.85.tar.gz

  2. Go to the Rational DOORS Web Access installation directory.
    For example:
    C:\Program Files\IBM\Rational\DOORS Web Access\9.version

  3. Rename the server directory to server.orig.

  4. Extract the downloaded Apache Tomcat core compressed file to ./server in the Rational DOORS Web Access installation directory.

  5. Delete the contents of the ./server/webapps folder

  6. Copy the following jar files from your ./server.orig/lib directory to ./server/lib
    commons-logging-1.1.x.jar
    dwa-catalina.jar
    log4j-1.2.x.jar
    log4j.properties

  7. Remove the following jar files from the ./server/lib directory
    tomcat7-websocket.jar
    websocket-api.jar

  8. Copy your ./server.orig/festival directory to ./server/festival.

  9. Copy the ./server.orig/conf/server.xml file to ./server/conf/server.xml.

  10. Copy ./server.orig/webapps/*.war to ./server/webapps.

  11. Optional: Copy any customized files from the ./server.orig directory to ./server.

  12. UNIX systems only: Run the ./configure-festival.sh command, as described in the help topic Installing the web access server and the web access broker on Linux or Solaris systems.
