Queue service interval events examples

This section provides progressively more complex examples to illustrate the use of queue service interval events.

The figures accompanying the examples have the same structure:

• The top section is a graph of queue depth against time, showing individual MQGET calls and MQPUT calls.

• The middle section shows a comparison of the time constraints. There are three time periods that consider:

  • The user-defined service interval.

  • The time measured by the service timer.

  • The time since event statistics were last reset (TimeSinceReset in the event data).

• The bottom section of each figure shows which events are enabled at any instant and what events are generated.

The following examples illustrate:

• How the queue depth varies over time.

• How the elapsed time as measured by the service timer compares with the service interval.

• Which event is enabled.

• Which events are generated.
