Specifying the maximum waiting time for reading from service-controlled queues

At generation it is possible to set the maximum length of time that a service is permitted to wait for a message for a queue. This maximum wait time may be defined separately for the dialog and asynchronous services (MAX statement, QTIME operand). This ensures that a terminal user or client does not have to wait several minutes for the system to react to an error in a UTM program unit, or that a resource remains blocked for too long.

MAX statement in section "MAX - define UTM application parameters" The following operands are used to specify the maximum length of time that a service is permitted to wait for a message in a service-controlled queue:

• QTIME=

  Specification of the maximum waiting time in seconds (default: 32767 seconds). You can define separate maximum values for the waiting time for the dialog or asynchronous services.
  If a greater waiting time is specified in a program unit run than specified in QTIME then openUTM resets the waiting time to the value defined here.
