Configure client server communications

Do not modify the following settings without first consulting
BlackBerry AtHoc
 customer support.
You must have system administrator permissions to configure client server communications.
Most settings in the Desktop App settings page are established during the initial installation and configuration with the assistance of
BlackBerry AtHoc
 customer support. The settings in the Client Server Communications section of the Desktop App settings page are used to configure the settings that govern communication between the
BlackBerry AtHoc
 server and the desktop app, and the rate at which new alerts and user configuration updates are checked.
  1. In the navigation bar, click The Settings icon.
  2. In the
    Devices
     section, click
    Desktop App
    .
  3. On the
    Desktop App
     window, scroll down to the
    Client Server Communications
     section.
  4. Select a value from the
    Check Update Interval
     list.
    The Check Update Interval (CU) determines how frequently the desktop app polls the server for updates, including alerts. A lower value causes end users to receive desktop pop-up alerts sooner. A higher value causes users to receive desktop pop-up alerts later. The minimum value is 30 seconds. The maximum value is 15 minutes. The recommended value is 2 minutes.
  5. Select a value from the
    Reconnect Interval
     list.
    The Reconnect Interval specifies the interval the desktop app waits before attempting to contact the server again when the connection is lost. The minimum value is 1. The maximum value is 10. The recommended value is 2.
  6. Select a value from the
    Recovery Interval
     list.
    The Recovery Interval specifies the number of check update intervals the desktop app waits before attempting to contact the server again when the server responds to a Sign On (SO) or CU with an error. The minimum value is 1. The maximum value is 10. The recommended value is 2.
  7. Enter a value in the
    Start-up Delay
     field.
    The Start-up Delay setting is a fractional value between 0 and 1 inclusive that is used to determine the amount of delay before the desktop app first attempts to sign on. A value of 0 specifies no delay and a value of 1 specifies to wait one full check update interval. A value of .5 specifies a delay of 50% of the check update interval.
  8. Enter a value in the
    Communication Session Expires After
     field.
    This option determines when the desktop app session is reset on the server. The default value is 86400 seconds (24 hours). When the desktop app session expires, the desktop app performs a sign on at the next CU.
  9. Enter a value in the
    Override Default Communication Session Expiration Time After
     field.
    This setting cleans up system sessions that were created by the SYSTEM user. Sessions that are created by the SYSTEM user when desktop apps are deployed with the installation script and RUNAFTERINSTALL is set to "Y". Sessions can be created by the SYSTEM user when the installation script is used to update computers after the desktop app is installed.
    This option also enables desktop apps to perform a sign on in environments where users do not turn off their computer. This option provides a way to configure desktop apps to redirect during SO.
