Scheduler
|
Specifies the scheduler type for this inbound communication.
There are two options:
-
Timer Service:
This scheduler is configured using the At
Fixed Rate, Delay, and Period properties.
-
Work Manager: The
task is scheduled through the J2EE Work Manager. Work Manager is supported
by J2EE (JCA 1.5 and above). This
scheduler is configured using the Delay and Period properties.
|
Select Timer Service or Work Manager.
If your container doesn’t support JCA Work Manager, select Timer Service .
|
|
Schedule Type
|
Applies to both the Timer Service or
the Work Manager. Specifies whether
the task is scheduled to occur once or be repeated.
|
Select OneTime or Repeated.
|
|
Delay
|
Applies to both the Timer Service or
the Work Manager. Specifies, in
milliseconds, the length of delay time before the task is executed.
|
An integer indicating the amount of time, in milliseconds, before
the task is executed (1000 milliseconds is equal to 1 second).
|
|
Period
|
Specifies the wait interval in milliseconds between successive
repeated task executions. This is used for the Repeated Schedule Type (see Schedule Type).
Applies to both the Timer Service or
the Work Manager.
|
An integer indicating the amount of time, in milliseconds, between
successive task executions (1000 milliseconds is equal to 1 second).
Enter a positive integer. The configured default is 100. Lowering this value may increase the
number of transactions per second.
|
|
At Fixed Rate
|
Specific to the Timer Service configuration
only. Specifies whether a Fixed-Rate execution
or Fixed-Delay execution is used.
This is used for the “Repeated” schedule type by the “Timer
Service” scheduler.
-
Fixed-Rate: A fixed-rate
execution means that 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 will occur in rapid succession to catch up. In the long run, the frequency
of execution will be exactly the reciprocal of the specified period
(assuming the system clock underlying Object.wait(long) is accurate).
-
Fixed-Delay: A
fixed-delay execution means that 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 will be delayed as well. As a result, the frequency
of execution will generally be slightly lower than the reciprocal
of the specified period (assuming the system clock underlying Object.wait(long)
is accurate).
|
Select True or False.
True indicates that a fixed-rate
execution is used. False indicates
that a fixed-delay execution is used.
