Db2 MQI services

A service describes a destination to which an application sends messages or from which an application receives messages. Db2 Message Queue Interface (MQI) services are defined in the Db2 table SYSIBM.MQSERVICE_TABLE.

The MQI-based Db2 MQ functions use the services that are defined in the Db2 table SYSIBM.MQSERVICE_TABLE. This table is user-managed and is typically created and maintained by a system administrator. This table contains a row for each defined service, including your customized services and the default service that is provided by Db2.

The application program does not need know the details of the defined services. When an application program calls an MQI-based Db2 MQ function, the program selects a service from SYSIBM.MQSERVICE_TABLE by specifying it as a parameter.
