Servers for the data service adapters

It is recommended that you install the data service adapters on an existing application server, although you can install the adapters on a new server. You can install several Rational® Publishing Engine data service adapters on the same server. The recommended deployment depends on the version and the configuration of the product.

The recommendation is to deploy the data service adapters on an existing application server. If you do not have an application server on which to deploy the adapters, you need to install either IBM® WebSphere® Application Server or Apache Tomcat and to deploy the data service adapters to the application server. Supported data service adapters include:

You can install more than one adapter on the same server. However, installing more than one adapter can cause performance issues. If you plan to install more than one adapter on a server, coordinate document generation times so that the computer is not overloaded.

If more than one Rational product is installed on a computer, all products must have the same version. For example, if you have an application server for Rational ClearQuest 7.1 data, you can use the same computer to install the 7.1 clients of Rational ClearCase and Rational RequisitePro, but you cannot install a 7.0 version of Rational ClearCase or Rational RequisitePro.

The following tables show the recommended configuration for deploying the data service adapters.

Rational product Recommended configuration for the IBM Rational ClearQuest adapter
Rational ClearQuest 7.0, 7.0.1 A new server configured as the IBM Rational Publishing Engine Data Service server, with Rational ClearQuest 7.1 installed.

For optimum performance, put the Rational ClearQuest adapter and the Rational ClearQuest database on the same local area network.

Rational ClearQuest 7.1 without Rational ClearQuest Web Any supported operating system that has Rational ClearQuest 7.1 installed. An existing server or a new server can be used.

For optimum performance, put the Rational ClearQuest adapter and the Rational ClearQuest database on the same local area network.

Rational ClearQuest with Rational ClearQuest Web The computer where Rational ClearQuest Web is deployed. Create a WebSphere Application Server instance to deploy Rational Publishing Engine Data Services. During the installation of Rational Publishing Engine data services, select the instance of WebSphere Application Server that runs Rational ClearQuest. The new and the existing WebSphere Application Server instances coexist.

For optimum performance, put the Rational ClearQuest adapter and the Rational ClearQuest database on the same local area network.

Rational product Recommended configuration for the IBM Rational ClearQuest adapter
ClearCase 7.0, 7.0.1 with ClearCase remote client The computer where the remote client server is deployed. During the installation of Rational Publishing Engine Data Services, create WebSphere Application Server instance for deploying the data service.
ClearCase 7.1 without ClearCase remote client A new server configured as the Rational Publishing Engine Data Service server, with the current version of Rational ClearCase installed.
ClearCase 7.1 with ClearCase remote client The WebSphere Application Server where Rational ClearQuest Remote Client is installed. During the installation of Rational Publishing Engine Data Services, select the instance of WebSphere Application Server that runs Rational ClearQuest Remote Client.
Rational product Recommended configuration for the IBM Rational RequisitePro adapter
Rational RequisitePro 7.0, 7.0.1 with RequisiteWeb An existing Rational RequisitePro server, with a new WebSphere Application Server instance.
Rational RequisitePro 7.1 without RequisiteWeb Any application server that has Rational RequisitePro installed. An existing server or a new server can be used.
Rational RequisitePro 7.1 with RequisiteWeb Either of the following options:
  • An existing Rational RequisitePro server, with an existing WebSphere Application Server instance of.
  • A new Rational Publishing Engine Data Services server, with Rational RequisitePro installed.
Rational product Recommended computers for installing the Rational TestManager adapter
TestManager 7.0, 7.0.1, 7.0.2 Any application server that has Rational TestManager installed. An existing server or a new server can be used.
