tibemsMsg_SetPriority Function Purpose Set the priority header of a message. C Declaration tibems_status tibemsMsg_SetPriority( tibemsMsg message, tibems_int value ); COBOL Call CALL "tibemsMsg_SetPriority" USING BY VALUE message, BY VALUE value, RETURNING tibems-status END-CALL. message has usage pointer. Parameters Parameter Description message Set the priority of this message. value Set the priority to this value. Remarks Sending calls set the priority header automatically. The JMS specification defines this call for symmetry. Sending calls record the priority of a message in this header, based on either a property of the producer, or on a parameter to the send call. The JMS specification defines ten levels of priority value, from zero (lowest priority) to 9 (highest priority). The specification suggests that clients consider 0–4 as gradations of normal priority, and priorities 5–9 as gradations of expedited priority. Priority affects the order in which the server delivers messages to consumers (higher values first). The JMS specification does not require all providers to implement priority ordering of messages. (EMS supports priorities, but other JMS providers might not.) See Also tibemsMsg_GetPriority on page 46 tibemsMsgProducer_GetPriority on page 189 tibemsMsgProducer_SetPriority on page 200
