Configure services and components

You configure service components using the queue manager configuration files, except on Windows systems, where each queue manager has its own stanza in the Registry.

Procedure

1. Add stanzas to the queue manager configuration file to define the service to the queue manager and specify the location of the module.

   Each service used must have a Service stanza, which defines the service to the queue manager.

   For each component within a service, there must be a ServiceComponent stanza. This identifies the name and path of the module containing the code for that component.

   For more information, see Service stanza format and Service component stanza format.

   The authorization service component, known as the Object Authority Manager (OAM), is supplied with the product. When creating a queue manager, the queue manager configuration file (or the Registry on Windows systems) is automatically updated to include the appropriate stanzas for the authorization service and for the default component (the OAM). For the other components, we must configure the queue manager configuration file manually.

   The code for each service component is loaded into the queue manager when the queue manager is started, using dynamic binding, where this is supported on the platform.

2. Stop and restart the queue manager to activate the component.

• Service stanza format
  The Service stanza contains the name of the service and the number of entry points defined for the service.
• Service component stanza format
  The Service and ServiceComponent stanzas can occur in any order.
• Configure authorization service stanzas on UNIX and Linux
  On UNIX and Linux, each queue manager has its own queue manager configuration file.
• Configure authorization service stanzas on Windows
  On IBM MQ for Windows each queue manager has its own stanza in the registry.
• Configure name service stanzas on UNIX and Linux
  On UNIX and Linux systems, each queue manager has its own queue manager configuration file.
• Refreshing the OAM after changing a user's authorization
  In IBM MQ, we can refresh the OAM's authorization group information immediately after changing a user's authorization group membership, reflecting changes made at the operating system level, without needing to stop and restart the queue manager. In order to do this, issue the REFRESH SECURITY command.
