Timer Service
– Available for Java EE, this scheduler is configured using the
At Fixed Rate
,
Delay
, and
Period
properties.
■
Work Manager
– Available for Java EE (JCA 1.5 and above), this scheduler is configured
using the
Delay
and
Period
properties.
TABLE 7
Connectivity Map - TCPIP Inbound Schedules - Listener Schedule
Name
Description
Scheduler
The scheduler type for this inbound communication. Select one of the following
options:
■
Timer Service
– The task is scheduled through the Java EE Timer Service.
Timer Service is supported by Java EE.
■
Work Manager
– The task is scheduled through the Java EE Work Manager.
Work Manager is supported by Java EE (JCA 1.5 and above).
If your container doesn’t support JCA Work Manager, select
Timer Service
.
Schedule Type
This property, though visible from the Properties Editor, is disabled. The only
available schedule type is Repeated, indicating that the task is scheduled for
repeated execution at regular intervals defined by the
Period
property.
Delay
An integer 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
An integer indicating the length of time (in milliseconds) between successive task
executions. This property applies to both the Timer Service and the Work
Manager.
At Fixed Rate
An indicator of whether a fixed-rate execution or fixed-delay execution is used.
This property applies to the Timer Service configuration only. Select
true
to
indicate fixed-rate; select
false
to indicate fixed-delay.
■
Fixed-Rate
– Each execution is scheduled relative to the scheduled time of
the initial execution. If an execution is delayed for any reason (such as
garbage collection or other background activity), two or more executions
occur in rapid succession to “catch up.” In the long run, the frequency of
execution is exactly the reciprocal of the specified period, assuming the
system clock underlying
Object.wait(long)
is accurate.
■
Fixed-Delay
– Each execution is scheduled relative to the actual time of the
previous execution. If an execution is delayed for any reason (such as garbage
collection or other background activity), subsequent executions are delayed
as well. As a result, the frequency of execution is generally slightly lower than
the reciprocal of the specified period, assuming the system clock underlying
Object.wait(long)
is accurate.
