Listener failover
This topic pertains to a clustered listener configuration. As long as at least one Unica Campaign listener is viable, failover should occur without disruption.
- Network issues (TCP/IP)
- Listener (software) failure
- Hardware failure
In rare cases, there may be a non-recoverable situation and any work that is in memory will be lost. In this case, a message alerts users to the situation so they can make a note of any flowchart changes that need to be redone.
To avoid possible loss to flowchart work, best practice is to configure checkpointFrequency and autosaveFrequency in the Unica Campaign partition settings. You can override the global configuration settings for individual flowcharts, using the option.
