Controlling Concurrent Managers
This essay explains how to control your concurrent managers.
Manager States
Individual managers read requests to start concurrent programs and actually start
programs running when certain conditions are satisfied, such as the manager's work
shift definition, number of target processes, and specialization rules.
You can start, shut down, or reset the concurrent managers at any time. Oracle
E-Business Suite provides an Internal Concurrent Manager that processes these
commands. You can issue commands either to individual managers, or, by altering the
state of the Internal Concurrent Manager, you can control every manager at once.
Note: Start your concurrent managers on machines with hostnames of
30 or fewer characters. Managers may fail to start on machines with
longer hostnames.
Starting Individual Managers
You can restart or activate managers on an individual basis. Restarting a concurrent
manager forces the Internal Concurrent Manager to reread the definition for that
concurrent manager. Activating a manager cancels a previous command to deactivate
it, and allows the Internal Concurrent Manager to submit a request to start that
manager when its work shift starts.
You should restart an individual manager when you:
•
modify its work shift assignments
•
modify a work shift's target number of processes
•
modify its specialization rules
•
change a concurrent program's incompatibility rules
Deactivating Individual Managers
When you shut down an individual manager, you can choose whether to abort all
requests and deactivate the manager immediately, or to allow it to finish processing its
current requests before deactivating.
If you choose to Deactivate the manager, requests that are currently running are
