■TimerService – Available for Java EE, this scheduler is congured using the At Fixed Rate,
Delay,and Period properties.
■WorkManager – Available for Java EE (JCA 1.5 and above), this scheduler is congured
usingthe Delay and Period properties.
TABLE7 ConnectivityMap - TCPIP Inbound Schedules - Listener Schedule
Name Description
Scheduler Thescheduler type for this inbound communication. Select one of the following
options:
■TimerService – The task is scheduled through the Java EE Timer Service.
TimerService is supported by Java EE.
■WorkManager – The task is scheduled through the Java EE Work Manager.
WorkManager is supported by Java EE (JCA 1.5 and above).
Ifyour container doesn’t support JCA Work Manager, select Timer Service.
ScheduleType Thisproperty, though visible from the Properties Editor, is disabled. The only
availableschedule type is Repeated, indicating that the task is scheduled for
repeatedexecution at regular intervals dened by the Period property.
Delay Aninteger indicating the length of time (in milliseconds) before the task is
executed.This property applies to both the Timer Service and the Work Manager.
Period Aninteger indicating the length of time (in milliseconds) between successive task
executions.This property applies to both the Timer Service and the Work
Manager.
AtFixed Rate Anindicator of whether a xed-rate execution or xed-delay execution is used.
Thisproperty applies to the Timer Service conguration only. Select true to
indicatexed-rate; select false to indicate xed-delay.
■Fixed-Rate– Each execution is scheduled relative to the scheduled time of
theinitial execution. If an execution is delayed for any reason (such as
garbagecollection or other background activity), two or more executions
occurin rapid succession to “catch up.”In the long run, the frequency of
executionis exactly the reciprocal of the specied period, assuming the
systemclock underlying Object.wait(long) is accurate.
■Fixed-Delay– Each execution is scheduled relative to the actual time of the
previousexecution. If an execution is delayed for any reason (such as garbage
collectionor other background activity), subsequent executions are delayed
aswell. As a result, the frequency of execution is generally slightly lower than
thereciprocal of the specied period, assuming the system clock underlying
Object.wait(long)is accurate.
