Tuning the Reconciler Server Settings

Although the default settings are usually adequate, you can sometimes improve Reconciler performance if you adjust the following settings on the Edit Server Settings page:

• Parallel Resource Limit. Specifies the maximum number of resource threads that the Reconciler can process in parallel.

  Resource threads allocate work items to worker threads, so if you add additional resource threads, you might also have to increase the maximum number of worker threads.

• Minimum Worker Threads. Specifies the number of processing threads that the Reconciler always keeps open.

• Maximum Worker Threads. Specifies the maximum number of processing threads that the Reconciler can use. The Reconciler starts only as many threads as the workload requires, which places a limit on that number. Worker threads automatically close if they are idle for a short duration.

During idle times, the threads stop if they have no work to do, but only down to the minimum number of threads specified. As the load increases, the Reconciler adds more threads until the maximum number of threads is reached. The Reconciler never has less than the minimum number of threads or more than the maximum.

Generally, more threads allow more concurrency. However, at some point, too many threads can put too much load on the machine or just do not provide additional benefit. Because the worker threads are typically reading and writing User and Account objects, having too much concurrency might overload the Waveset repository RDBMS.

Recommending generic, optimal settings is not possible because deployments are so different. Reconciler settings must be adjusted differently for each deployment environment.

To Change the Reconciler Server Settings

Perform the following steps to change the Reconciler server settings:

1. Log into the Administrator interface.

2. Click the Configure -> Servers -> Reconciler tabs.

3. When the Edit Server Settings page is displayed, adjust the settings as necessary.

   See Editing Default Server Settings for more information.
