2-16 Oracle Fusion Middleware Performance and Tuning Guide

2.9.4 Tuning Oracle WebCenter Concurrency

Oracle WebCenter has its own controls for managing concurrency. See Configuring Concurrency Management in Oracle Fusion Middleware Administrators Guide for Oracle WebCenter.

2.9.5 Tuning BPEL Concurrency

The Oracle BPEL Process Manager has its own thread controls and specialized tuning. See Section 13.2.1, BPEL Threading Model .

2.10 Set Logging Levels

The amount of information that applications log depends on how the environment is configured and how the application code is instrumented. To maximize performance it is recommended that the logging level is not set higher than the default INFO level logging. If the logging setting does not match the default level, reset the logging level to the default for best performance. Once the application and server logging levels are set appropriately, ensure that the debugging properties or other application level debugging flags are also set to See Also: For more information on how to use custom Work Managers to customize thread management, and when to use custom work managers, see the following: ■ Tune Pool Sizes in Oracle Fusion Middleware Performance and Tuning for Oracle WebLogic Server ■ Thread Management in Oracle Fusion Middleware Performance and Tuning for Oracle WebLogic Server ■ MDB Thread Management in Oracle Fusion Middleware Performance and Tuning for Oracle WebLogic Server ■ Using Work Managers to Optimize Scheduled Work in Oracle Fusion Middleware Configuring Server Environments for Oracle WebLogic Server ■ Avoiding and Managing Overload in Oracle Fusion Middleware Configuring Server Environments for Oracle WebLogic Server You can use Oracle WebLogic Administration Console to view general information about the status of the thread pool such as active thread count, total thread count, and queue length. You can also use the Console to view each applications scoped work manager metrics from the Workload tab on the Monitoring page. The metrics provided include the number of pending requests and number of completed requests. For more information, see Servers: Monitoring: Threads and Deployments: Monitoring: Workload in the Oracle Fusion Middleware Oracle WebLogic Server Administration Console Online Help. The work manager and thread pool metrics can also be viewed from the Oracle Fusion Middleware Control.

To avoid performance impacts, do not set log levels to levels that produce more diagnostic messages, including the FINE or TRACE levels.
