Use an MQ Service to discover artifacts from IBM® MQ queue managers. You can then use these artifacts in a message flow.
An MQ Service defines the interaction between IBM Integration Bus and IBM MQ applications. You can create an MQ Service for each queue manager. An MQ Service definition is created for each MQ Service that you discover, and has the extension .service. The MQ Service definition specification describes the resources that you discover. This specification also explains how to represent IBM MQ applications as web services by using IRIs and WSDL. For more information, see SupportPac MA93: IBM MQ - Service Definition specification.
You can use an MQ Service to configure the properties of an MQ node. You can reuse an MQ Service across multiple MQ nodes, which simplifies the MQ connectivity within your message flows.
- A WSDL file that contains connection information about the queue manager and resulting queue names. The WSDL file is compliant with the IBM MQ Service definition specification (MA93).
- An XSD file for the input message, and an XSD file for the output message, if any are specified in the MQ Service editor. The XSD files contain XML structures that describe service input and output.
- An XML file that contains metadata that is used during the discovery process. The IBM Integration Toolkit uses this file to store state information from the MQ Service editor, and perform iterative discovery of previously discovered artifacts.
- Optional: an MQEndpoint policy that contains the connection property values for the specified queue manager. When you configure an MQ node by using the MQ Service, the MQEndpoint policy is automatically attached to the node. In the IBM Integration Toolkit, you can choose whether you want an MQEndpoint policy to be automatically generated when you create an MQ Service. The default option is Ask if a policy needs to be generated. To change this option, click .
- Connect to a queue manager. The MQ Service editor connects to the specified queue manager, to discover all the existing queues that belong to it.
- Define whether the MQ Service is one-way or request-response.
- Identify the queue or queues that you need, depending on whether the MQ Service is one-way or request-response.
- Optional: create an MQEndpoint policy.
