Configuring High Availability for Entities

Configure high availability for an entity to ensure service continuity when the active entity goes down or you stop the node for administrative purposes. To configure high availability for an entity, start a

EDS Node

with the same name on two or more hosts. When you start a node with the same name on multiple hosts, the entity on one of the nodes becomes active. If you stop the node on which the active entity is running or if the primary node fails, the entity on one of the standby nodes becomes active.

Additional Configuration Tasks for Source Services

The following table describes additional tasks for configuring high availability for a particular type of source service:

Source Service Type	Additional Configuration Tasks
MQTT	No additional tasks.
Flat File, JSON	Configure the source application instances to log data to a file on a shared network drive and specify the shared location for the source service.
TCP	Configure the source application to connect to the new active node when fail over occurs.
Syslog	For information about how to set up high availability for a Syslog target service, contact Informatica Global Customer Support.
UDP	High availability is not supported.

Additional Configuration Tasks for Target Services

For some types of services, you might need to perform additional tasks to set up high availability.

The following table describes additional tasks for configuring high availability for a particular type of target service:

Target Service Type	Additional Configuration Tasks
Cassandra, PowerCenter, RulePoint	No additional tasks.
HDFS	Perform advanced configuration tasks for supporting high availability.
