Enabling and disabling services

In a distributed installation, you can send certain types of requests to specific computers by enabling or disabling the installed services.

For example, to dedicate a computer to running and distributing reports, you can disable the presentation service on an Application Tier Components computer.

Note: The default values for dispatcher service and presentation service are false on computers that only have Content Manager installed. On all other types of installations, the default values are true.

If you installed all components on several computers, you can disable appropriate services on each computer to get the distributed configuration you require. Requests are only sent to dispatchers where a given service is enabled.

Disabling a service prevents the service from loading into memory. When disabled, services do not start and therefore do not consume resources. The service does not run until you enable it.

If you disable the dispatcher service, the dispatcher-related services are disabled. Only dispatcher services that are enabled can process requests.

Restriction: When restarting services manually, (if applicable) the ApacheDS - cognos service must be started before the IBM Cognos service.

Procedure

  1. Start IBM® Cognos® Configuration.
  2. In the Explorer window, under Environment, click IBM Cognos services.
  3. In the Properties window, click the Value next to the service that you want to disable or enable.

    By default, all services are enabled.

  4. Click the appropriate state for the services:
    • To disable the service, click False.
    • To enable the service, click True.
    When restarting services manually, (if applicable) the ApacheDS - cognos service must be started before the IBM Cognos service.
  5. From the File menu, click Save.
