Installing Rational Agent Controller

Rational® Agent Controller (RAC) is a daemon process that provides the mechanism by which client applications either launch new host processes, or attach to agents that coexist within existing host processes. WebSphere Message Broker uses RAC to provide debugging facilities for message flows deployed to a running broker. Other IBM products might also use RAC for services.

Before you can use the flow debugger, install RAC on all systems where you run the brokers in which you want to debug message flows. Also, check that the RAC component installed on the broker has TCP/IP connectivity to the system on which the Message Brokers Toolkit is running, to enable it to communicate with the RAC client which is embedded in the Message Brokers Toolkit.

To use RAC with WebSphere Message Broker brokers, complete the following steps:

  1. Install RAC from the supplemental CD or DVD supplied with WebSphere Message Broker using the full instructions provided in the file install.html located in the root directory of the RAC component on CD or DVD.

    For successful operation with the broker, you must disable the security option during installation. For more details, see the install.html file and the appropriate topic for your operating system:

    Start of changeTo control access within your domain, install RAC behind a firewall and stop the RAC service if you do not use the flow debugger. To configure RAC to be used with WebSphere Message Broker with a firewall, see Configuring RAC for use with a firewall.End of change

  2. In the workbench, select the option in the Debug preference page that corresponds to your broker configuration, as documented in Setting flow debug preferences.
