High Availability (HA) Issues

High Availability (HA) allows users to run more than one Itential Platform (IP) instance in a data center. For example, you may have a data center on the East Coast with 6 active instances of IP running virtually. Meanwhile, you have a back-up on the West Coast that contains 6 instances of IP running in a passive state for disaster recovery. If task execution fails in a HA IP environment, you can determine the specific IP server that attempted to execute the task by referencing the Server ID of the failed task.

Each IP server in an HA environment has a unique Server ID property that is defined in one of two ways:

• Manually via the serverName property of the properties.json file located in the IP installation directory.
• Automatically by combining the MAC address and IP port values and hashing them.

When a server attempts to execute a task, its Server ID property is added to the Task Details panel of that task.

Make sure there are no connection issues affecting the server identified by the Server ID property of a failed task.
