  - Installation of Rational® Test Control Panel
    You can find information about installing IBM® Rational® Test Control Panel from the IBM Rational Test Workbench, IBM Rational Test Virtualization Server, or IBM Rational Performance Test Server package.
  - Upgrading Rational® Integration Tester Agent
    In general, you can upgrade from earlier versions of Rational® Integration Tester Agent to the most recent version without having to uninstall the software. Use the Installation Manager Update option to upgrade the software.
  - License management
    As a purchaser of an IBM® Rational® software product, you can choose from the different types of product licenses that you can deploy to use the product.
  - Configuring Rational® Integration Tester Agent
    After you install Rational® Integration Tester Agent, you must edit or modify the attributes in the Agent.config file for the features that you want to test by using the agent. You need to configure the libraries to enable testing the SUT based on certain technologies and also set up the required proxies for enabling testing.
  - Running Rational® Integration Tester Agent on Microsoft™ Windows™
    On computers running Microsoft™ Windows™, the agent is typically installed and run as a Windows service.
  - Running Rational® Integration Tester Agent on Unix-like systems
    On Unix-like systems, you can start Rational® Integration Tester Agent by running the Agent executable in the root of the Rational Integration Tester Agent installation directory (for example, /opt/IBM/RIT-Agent/).
  - Troubleshooting: Rational® Integration Tester Agent
    You can use workarounds to common problems that you might encounter when you install and run the Rational® Integration Tester Agent.
  - HTTP/TCP proxy setup
    The process of configuring applications to use the HTTP/TCP proxy varies according to the application.
    - Modifying the configuration settings of the HTTP/TCP proxy
      To change the server address, log level, and other settings, you can modify the registration.xml file of the HTTP/TCP proxy.
    - Configuring a HTTP(S) reverse proxy or TCP port forwarding
      The reverse proxy capability allows applications that are unable to configure HTTP(S) forward proxying to address the proxy directly and have it forward these requests to a configured destination, which is also applicable for forwarding TCP-based communications.
    - Advanced HTTP and TCP proxy configuration
      The HTTP protocol runs on top of the TCP protocol, but provides extra information about the message destination. For that reason, the two proxies are configured differently.
    - Configuring Apache Tomcat to use HTTP/TCP proxy
      You must modify the Java™ virtual machine (JVM) so that Apache Tomcat can use an HTTP/TCP proxy. You can configure Apache Tomcat by configuring JVM options in the Tomcat startup script.
    - Configuring WebSphere® Application Server to use HTTP/TCP proxy
      You must modify the Java™ virtual machine (JVM) so that WebSphere® Application Server can use an HTTP/TCP proxy. You can do this change by setting some JVM options through the administrative console.
    - HTTP/TCP proxy logs
      To help you troubleshoot HTTP/TCP proxy problems, a number of logging methods are available for the HTTP/TCP proxy.
    - Starting and stopping the HTTP/TCP proxy
      To route and record HTTP(S) and TCP traffic with Rational® Test Control Panel and Rational Integration Tester, you must start the HTTP/TCP proxy. If the proxy is installed as a Windows service, you can configure it for an automatic start on start of the system or for a manual start on demand.
    - Programmatic custom certificate creation in proxy
      When an HTTPS connection is established with an HTTP/TCP proxy, the certificate that is presented to the client by the proxy is retrieved from an existing keypair that represent the intended endpoint or is generated as the default certificate by the proxy and is signed by the private key in the keystore that is configured in the registration.xml. Ordinarily, this mechanism is sufficient. If full control over the generation of certificates is required, an alternative advanced approach is available. The approach requires that custom code is written to generate and sign the required certificates.
  - Setting up the JDBC proxy
    After you install the JDBC proxy, you must deploy the proxy into the Java™ virtual machine (JVM) of the relevant applications, set up the proxy for use, and verify that it is deployed.
  - Administering IBM® Rational® Test Control Panel Rational® Test Control Panel
    is a server-based web application providing a central repository for virtualized services. The Rational® Test Control Panel allows you to use virtual services published with Rational Integration Tester to create, share, and deploy virtualized test environments in IBM® Rational Test Virtualization Server.
- Tester Guide
  This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing.
- Test Manager Guide
  This guide describes the tasks that you can perform for tracking the quality of the application. This guide is intended for Test Managers.
- Security Considerations
  You can take certain actions to ensure that your installation is secure, customize your security settings, and set up user access controls.

Configuring Apache Tomcat to use HTTP/TCP proxy

You must modify the Java™ virtual machine (JVM) so that Apache Tomcat can use an HTTP/TCP proxy. You can configure Apache Tomcat by configuring JVM options in the Tomcat startup script.

Before you begin

You must have the required privileges to edit the Apache Tomcat startup script.

Procedure

Locate the Tomcat startup script.
The location of the script depends on the OS you are using. The location can be as follows:
- In Microsoft™ Windows™, at %CATALINA_HOME%\bin\catalina.bat
- In Unix-like systems, at $CATALINA_HOME/bin/catalina.sh
Open the catalina.sh file for editing and add the following JAVA_OPTS option for the proxy:

JAVA_OPTS="-Dhttp.proxyHost=<Host name or IP address of HTTP/TCP proxy>-Dhttp.proxyPort=<Port number specified during installation>-Dhttps.proxyHost=<Host name or IP address of HTTP/TCP proxy>-Dhttp.proxyPort=<Port number specified during installation>-Djavax.net.ssl.trustStore=/opt/tomcat/bin/greenhat.jks -Djavax.net.ssl.trustStorePassword=passphrase"
Note: If you are setting up a HTTP/TCP proxy to support both HTTP and HTTPS, use the properties as http.proxyHost for the HTTP proxy and https.proxyPort for the HTTPS proxy.

For example, if you have installed Rational® Test Control Panel on a computer with the IP address as 101.25.87.99 and are using the default port 3128 for both HTTP and HTTPS, the options you set in the catalina.sh file are as follows:

JAVA_OPTS="-Dhttp.proxyHost=101.25.87.99 -Dhttp.proxyPort=3128 -Dhttps.proxyHost=101.25.87.99 -Dhttps.proxyPort=3128 -Djavax.net.ssl.trustStore=/opt/tomcat/bin/greenhat.jks -Djavax.net.ssl.trustStorePassword=passphrase"
Save and close the file.
Restart Tomcat for the changes to take effect.
