For MQSeries each request contains the following parameters. Unlike the TCP/IP protocols, there is no need to include the user id as a parameter, as MQSeries already includes this information in each message.
Job Identifier
Every job that you submit must have a non-empty identifier. You are free to choose this identifier. It is used for progress messages and by the ITP/DS monitor, but not internally for identification of request messages. This means that job identifiers do not necessarily have to be unique.
Service
The second parameter is also required and contains the name of the service that you want to run.
Optional Parameters
Every job that you submit can have zero or more additional parameters. In the ITP/Server administration program you define how these parameters are mapped to script parameters. When the mapping contains more parameters than those specified in a job then these parameters are assumed to be undefined.
