Liveliness QoS

See Policy or Return to Glossary

Liveliness QoS offers the following settings to detect failures on the publishing node:

AUTOMATIC
Infrastructure managed (default), leases are renewed automatically by the service. Only process failures can be detected this way.
MANUAL_BY_PARTICIPANT
Application managed, the entire Domain Participant renews its lease when one of its contained Entities asserts its liveliness, either explicitly or implicitly.
MANUAL_BY_TOPIC
Application managed, each Data Writer is responsible for renewing its own lease, either implicitly or explicitly. Source: OpenSplice Glossary
