Configure concurrent constraints for managed servers


Long-running tasks submitted to the managed executor service, the managed scheduled executor service, or the managed thread factory, need to create new threads that will not be managed as a part of WebLogic Server's self-tuning thread pool. Because an excessive number of running threads can have a negative affect on server performance and stability, you can specify the maximum number of running threads that are created by the concurrency utilities API.

For information about configuring and using the concurrent managed objects (CMOs) in Oracle WebLogic Server, see "Configuring the Concurrent Managed Objects" in Administering Server Environments for Oracle WebLogic Server.

To configure the concurrent contraints for a managed server:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the Domain Structure tree, select Environment > Server.
  3. Select Configuration > General > Concurrency.
    1. In Max Concurrent New Threads, enter the maximum number of concurrent new threads that can be created by all of the Managed Thread Factories in this managed server scope.
    2. In Max Concurrent Long Requests, enter the maximum number of concurrent long-running requests that can be submitted to all of the Managed Executor Services or Managed Scheduled Executor Services in this managed server scope.
  4. Click Save.
  5. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
