Installation prerequisites for Rational DOORS Web Access

Before you begin your product installation, prepare the installation and familiarize yourself with the components to install.
Important:
  • The Java™ Runtime Environment (JRE) must be installed on the server before you install Rational® DOORS® Web Access version 9.6.1 or later. The JAVA_HOME environment variable must be set to the path to the Java executable program; for example:
    C:\Program Files\IBM\Java8\jre
    For supported versions of JRE, see the System requirements for Rational DOORS Web Access.
  • If you upgrade Rational DOORS Web Access to version 1.5.0.1 or later, you can copy your old server.xml file to the new installation. If so, you must remove the reference to the Composite Application Framework (CAF) JavaScript library. Remove these lines from the server.xml file:
    <Context crossContext="true" debug="0" docBase="caf.war" path="/caf" reloadable="true">
       <Valve className="com.telelogic.dwa.catalina.valve.GlobalisationRequestInterceptor"/>
    </Context>
  • If you upgrade Rational DOORS Web Access to version 9.5.1 or later, you must also upgrade the interoperation server to the same version.
Installing Rational DOORS Web Access involves the installation of several discrete components.
