Configuring multiple Request Managers for a single computer

To use the maximum amount of hardware resources available at a single server computer, you can enable multiple Request Managers to run simultaneously.

The Registry Server controls the lifecycle of the Request Manager processes. Upon startup, the Registry Server creates an instance or instances of the Request Manager, which processes requests for a duration that is specified by the Automatic Recycle configurations. For more information about Automatic Recycle, see Configuring the Rational ClearQuest Web Request Manager for Automatic Recycle.

The maximum number of Request Managers that can exist on one computer is equal to the number of Central Processing Units (CPUs) available. If the number of Request Managers is configured incorrectly or it exceeds the number of available CPUs, then the Registry Server creates as many Request Managers as there are Central Processing Units (this is the default behavior).

To configure multiple Request Managers, edit the file, <INSTALLATION ROOT>\clearquest\cqweb\csm.properties to specify a value for the NUMBER_REQUEST_MANAGERS property that is equal to or less than the number of available CPUs. If you comment out this property, the default behavior is enabled.
Note: If you configure the NUMBER_REQUEST_MANAGERS property for more than four Request Managers and there are CPUs to support them, additional ports must be enabled in the port definitions;JTLRMISERVICEPORT, JTLRMISERVERFILESERVERPORTS, and CSM_ADAPTER_NOTIFICATION_LISTENER_PORT. Enable a new port for each additional Request Manager. For more information, see Ports used by the Rational ClearQuest Request Manager.

For examples of how multiple Request Managers startup up and shut down with the Automatic Recycle feature enabled, see Automatic Recycle based on time interval and Automatic Recycle based on number of requests.
