Configuring the service, task management, and schedules setting

This section describes several global parameters for tasks, services, and schedules.

  1. Go to System Administration > Sys Admin > System Settings.

  2. From the Section dropdown menu, select Service, Task Management and Schedules.

  3. Configure the following parameters:

  • Cycles

    Determines whether to allow off cycle reads. Select True to enable this feature or False to disable it.

    Defines the number of tasks to be scheduled in a group. When a schedule has more than 500 nodes, the cycle schedules tasks in 500 node increments.

    Defines the number of seconds to wait between queries for data events. Enter the number of seconds for the queue service to wait before checking for new data in the Data Event table.

    Defines the number of hours to look backwards to find a data event. Data events are sorted based on creation time.

    Defines the maximum threshold size for the data event queue. This is the number of rows from the DataEvent table that can be retrieved at one time.

    Defines the maximum number of cycle services to run.

    Determines the time between occurrence retrieval. This is for internal use by cycle services. When more than one occurrence is due at the same time, a single service may try to run more than one occurrence and slow the task scheduling.

  • Service Management

    Defines the number of minutes an alternate server waits after startup before claiming the assigned service. Set the value high enough so that the preferred server has adequate time to reboot before the alternate server claims the services.

    Defines the number of minutes an alternate server waits before claiming a service when the preferred server becomes unavailable.

    Defines the refresh interval for the Server, Services, and Unassigned Services panes on the System Admin > Service Management tab.

  • Task Runners

    Determines whether IEE adds an entry to the log every time the database is polled for tasks. Select True to log entries. Select False if you are debugging a particular scenario.

    Defines the maximum number of seconds to elapse before task type and validation updates are reloaded in the task runner cache. For example, if changes are being made to validation sets, the task runners will not pick up the changes until the cache is refreshed.

    Defines the maximum number of seconds to elapse before the task runner services polls the database for new tasks. The default value is 3.

    Determines when to restart the task runners to reclaim memory. After a task completes and the task runner cleans up its memory, if the used memory exceeds the threshold defined in this setting the task runner restarts. Enter the threshold in megabytes. This restart logic does not affect service runners.

    This setting helps you control when to restart task runners to reclaim memory.

  • Task Templates

    Defines the User ID of the default user to use for task templates. The default is ItronEE.

  • Tasks

    Defines the threshold for what tasks to consider high priority. Each task instance includes a priority. Task priorities range from 1 to 99. One is the highest priority and 99 is the lowest priority. If a runner sees multiple tasks that are ready to run, the task runner selects the task with the highest priority. The highest priority equates to the lowest number.
