Deployment topology considerations

You can deploy the Rational Adapter for HP ALM web application on either an Apache Tomcat application server or an IBM® WebSphere® Application Server.

Deploying the adapter web application (hpqm.war) includes the selection of an application server. That server can be either an Apache Tomcat application server or an IBM WebSphere Application Server.

Installing the adapter web application on its own application server, is recommended.

If you install the adapter web application and CLM on the same WebSphere Application Server or if the adapter and CLM are behind the same reverse proxy, such as IHS, you must change the HTTP session management cookie name. CLM and the adapter both use the same JSESSIONID cookie in an HTTP session. CLM sometimes resets the cookie when you log in, which causes the adapter to lose its session in some linking scenarios.

Apache Tomcat is configured to use ports 9080 and 9443 in the HPInstallDir/server/tomcat/conf/server.xml file. If necessary, change the port assignments as appropriate for your system. For example, if you run the HP adapter web application in the same instance of Apache Tomcat that is used by CLM, you must change the port assignments for the HP adapter. For more information, see Changing the port numbers for the application server.
