Setting communication thresholds and active job status updates for CASO

The communication statuses determine how the central administration server processes current and future jobs that are delegated to an unresponsive managed media server.

See What happens when CASO communication thresholds are reached.

You can change the thresholds that trigger the communication statuses when managed media servers become unresponsive. You can also set how often the managed media server sends active job status updates to the central administration server. The frequency affects the network traffic.

To set communication thresholds and the frequency of active job status updates

  1. On the central administration server's navigation bar, click Media Servers.

  2. Do one of the following:

    To set defaults to apply to a managed media server when it is installed

    Do the following in the order listed:

    • On the task pane, under Media Server Installation Tasks, click Configure managed media server defaults.

    • Proceed with step 3.

    To set defaults for an existing managed media server

    Do the following in the order listed:

    • Right-click the managed media server for which you want to configure settings, and then click Properties.

    • Click the Settings tab.

    • Proceed with step 3.

    To set defaults for a group of managed media servers in a pool

    Do the following in the order listed:

    • Select or create the media server pool that contains the managed media servers to which you want to apply new settings.

    • Right-click the media server pool, and then click Properties.

    • Click the Settings tab.

    • Check Apply these settings to all of the managed media servers in the pool.

    • Proceed with step 3.

  3. On the Settings tab, click Custom settings, and then click Edit Custom Settings.

  4. On the Configuration tab, change the defaults as appropriate:

    Communication Stalled (no more jobs are queued to the managed media server)

    Type the amount of time before the managed media server's status changes to Communication Stalled if the managed media server is unresponsive.

    The central administration server does not delegate jobs to the managed media server when it has a status of Communication Stalled. Job delegation resumes if the managed media server returns to an Enabled status before the threshold is exceeded.

    The default threshold is five minutes.

    No Communication (jobs are recovered from the managed media server)

    Type the amount of time before the managed media server's status changes from Communication Stalled to No Communication.

    When the status of the managed media server changes from Communication Stalled to No Communication, the central administration server marks the active jobs on the managed media server as Failed. The custom error-handling rule Recovered Jobs is applied to any job that is active when the No Communication status appears.

    The default threshold is 15 minutes.

    Send active job status updates in seconds to the central administration server

    Check Send active job status updates in seconds to the central administration server to send a job status update to the central administration server. You can adjust the number of seconds that a managed media server waits between sending job status updates to the central administration server. To preserve network bandwidth when many jobs are running, increase the amount of time between job update statuses. Decrease the amount of time if you want to send more updates.

    The default is 10 seconds, which provides near real-time monitoring. This setting is recommended only for fast network connections.

    For low bandwidth network connections, consider a setting of 120 seconds. This frequency allows updates to be displayed for a medium-sized job while still significantly decreasing the network traffic caused by job status updates.

    If you uncheck the check box, job status updates are not sent. Job progress is not displayed on the central administration server. When the job is complete, the Job History view on the central administration server is updated.

  5. Click OK.
