Scheduler Settings

The Scheduler component controls task scheduling in Waveset.

To configure scheduler settings on a particular server,

1. Follow the first two steps under Using the Administrator Interface to Configure Waveset.

2. Select the Scheduler tab.

   The following Use default options are enabled by default, which allows the scheduler to behave more efficiently when the Waveset server and repository are very busy. You can accept the default settings or deselect the Use default option to specify custom values.

   • Use default (Automatic). Sets the scheduler start up mode to Automatic.

   • Use default (false). Disables scheduler debug tracing.

   • Use default (100). Allows the scheduler to run a maximum of 100 tasks at any one time.

   • Use default (Allow any task). Allows any task to execute on the server.

   To specify custom settings for the scheduler, deselect one or more of the Use default options and configure the following options:

   • Scheduler Startup. Select a startup mode for the scheduler on this server:

     • Automatic. Starts when the server is started. This setting is the default startup mode.

     • Manual. Starts when the server is started, but remains suspended until manually started.

     • Disabled. Does not start when the server is started.

   • Tracing Enabled. Select this option to activate scheduler debug tracing to standard output on this server.

   • Maximum Concurrent Tasks. Select this option to specify the maximum number of tasks, other than the default, that the Scheduler will run at any one time. Requests for additional tasks above this limit will either be deferred until later or run on another server.

   • Task Restrictions. Specify the set of tasks that can execute on the server. To do this, select one or more tasks from the list of available tasks. The list of selected tasks can be an inclusion or exclusion list depending on the option you select. You can choose to allow all tasks except those selected in the list (the default behavior), or allow only the selected tasks.

3. Click Save to save your changes to the server settings.
