Changing the heartbeat interval You can change the frequency of the heartbeat signal that is sent by active Maximo Anywhere apps to MobileFirst Server. About this task At run time, a Maximo Anywhere app generates a heartbeat signal at a frequency that is defined at system level. The signal is used to determine whether the app is connected to MobileFirst Server. If connectivity is confirmed, the app uploads local data changes that are not yet saved to the server. The frequency of the heartbeat therefore determines the frequency of the automatic upload. You define the frequency of the heartbeat signal by specifying the interval between successive signals in worklight.properties file for the Maximo Anywhere project. The active setting applies to all applications that are built and deployed for the project. The default heartbeat interval is 1200 seconds (20 minutes. A lower value reduces the battery life of devices on which the Maximo Anywhere apps run. Procedure 1. Open the worklight.properties file in the maximoanywhere_home\Anywhere\ MaximoAnywhere\server\conf directory. 2. In the si.device.heartbeat.timeInterval property, specify the value of the heartbeat interval in seconds. 3. Save and close the file. 4. Deploy the project WAR file to MobileFirst Server. a. From the Server Configuration Tool, select Replace the project WAR file of
