You can create multiple instances for each cron task. You
can also reload instances of cron tasks, and you can delete instances
of cron tasks.
Creating cron task instances
Before you can run custom cron tasks, you must create
a cron task instance. You can create numerous instances for a single
cron task, which allows you to fine-tune these tasks to your business
needs.
Copying cron task instances
After you create a cron task instance, you can copy it
and change it. When you copy a cron task instance, the active status,
schedule, run as user ID, and parameter values are also copied.
Changing cron task instances
You can change the attributes or parameter values for a
cron task instance to suit your specific needs. You can change the
attributes or parameter values without restarting the application
server.
Deleting cron task instances
In the Cron Task Setup application, you can delete cron
task instances that you are no longer using. An instance is a copy
of a cron task that you can change to suit your business needs.
