Mapping of message delivery options flowing through the WebSphere MQ link

This topic shows the mapping of delivery options (qualities of service), when messages flow through the WebSphere® MQ link, between WebSphere Application Server service integration and a WebSphere MQ network.

Delivery options (also called qualities of service) differ between service integration and WebSphere MQ: Service integration offers a wider range of quality of service options.

When messages are received from a WebSphere MQ network, the default mapping of delivery options, carried out by the WebSphere MQ link receiver, is shown in the table below.

For details of delivery options definitions see Message reliability levels.

WebSphere MQ delivery option WebSphere Application Server service-integration delivery option (default)
Persistent Assured persistent
Nonpersistent Express™ nonpersistent

Example

Your administrator can select the attributes of the WebSphere MQ link receiver to alter the delivery option of inbound messages:
  • Inbound persistent messages can be altered, with the advanced attribute "inbound persistent message reliability," to reliable or assured.
  • Inbound nonpersistent messages can be altered, with the advanced attribute "inbound nonpersistent message reliability," to best effort or express or reliable.

When messages are sent to WebSphere MQ the mapping of the delivery options, carried out by the MQLinkSender, is shown in the table below.

WebSphere Application Server service-integration delivery option WebSphere MQ delivery option
Reliable persistent Persistent
Assured persistent Persistent
Reliable nonpersistent Nonpersistent
Express nonpersistent Nonpersistent
Best effort nonpersistent Nonpersistent
