Domain Failover

Domain Failover

The Service Manager on the master gateway node accepts service requests and manages the domain and services in the domain. The domain can failover to another node when the domain has multiple gateway nodes. Configure multiple gateway nodes to prevent domain shutdown when the master gateway node is unavailable.
The master gateway node maintains a connection to the domain configuration repository. If the domain configuration repository becomes unavailable, the master gateway node tries to reconnect when a user performs an operation. If the master gateway node cannot connect to the domain configuration repository, the master gateway node may shut down.
If the domain has multiple gateway nodes and the master gateway node becomes unavailable, the Service Managers on the other gateway nodes elect another master gateway node. The domain tries to connect to the domain configuration repository with each gateway node. If none of the gateway nodes can connect, the domain shuts down and all domain operations fail. When a master gateway fails over, the client tools retrieve information about the alternate domain gateways from the domains.infa file.
Application services running on the master gateway node will not fail over when another master gateway node is elected unless the application service has a backup node configured.
