■
Timer Service – Available for Java EE, this scheduler is congured using the At Fixed Rate,
Delay, and Period properties.
■
Work Manager – Available for Java EE (JCA 1.5 and above), this scheduler is congured
using the Delay and Period properties.
TABLE 7 ConnectivityMap - TCPIP Inbound Schedules- Listener Schedule
Name Description
Scheduler The scheduler typefor this inbound communication. Select oneof the following
options:
■
Timer Service –The task is scheduled through theJava EE TimerService.
Timer Service issupported by Java EE.
■
Work Manager –The task is scheduled throughthe Java EEWork Manager.
Work Manageris supported by Java EE (JCA 1.5and above).
If your container doesn’t support JCA Work Manager, select Timer Service.
Schedule Type This property, thoughvisible from the Properties Editor,is disabled. The only
available schedule typeis Repeated, indicating that the taskis scheduled for
repeated execution atregular intervals dened by the Periodproperty.
Delay An integer indicatingthe length of time (in milliseconds)before the task is
executed. This propertyapplies to both the Timer Serviceand the Work Manager.
Period An integer indicatingthe length of time (in milliseconds)between successive task
executions. This propertyapplies to both the Timer Serviceand the Work
Manager.
At FixedRate An indicator ofwhether a xed-rate execution or xed-delayexecution is used.
This property appliesto the Timer Service conguration only.Select true to
indicate xed-rate; selectfalse to indicate xed-delay.
■
Fixed-Rate – Each executionis scheduled relative to the scheduledtime of
the initial execution.If an execution is delayedfor any reason (such as
garbage collection orother background activity), two or moreexecutions
occur in rapidsuccession to “catch up.” In the longrun, the frequency of
execution is exactlythe reciprocal of the specied period,assuming the
system clock underlyingObject.wait(long) is accurate.
■
Fixed-Delay – Each executionis scheduled relative to the actualtime of the
previous execution. If an executionis delayed for any reason (suchas garbage
collection or otherbackground activity), subsequent executions are delayed
as well. As a result,the frequency of execution is generallyslightly lower than
the reciprocal ofthe specied period, assuming the systemclock underlying
Object.wait(long) is accurate.
