FAQ: What happens when the PowerCenter Domain Configuration Database fails?
Answer

The master gateway node maintains a connection to the domain configuration database.
If the domain configuration database becomes unavailable, the master gateway node tries to reconnect.
The resilience timeout period depends on user activity and whether the domain has one or multiple gateway node:

Single gateway node

If the domain has one gateway node, the gateway node tries to reconnect until a user or service tries to perform a domain operation.
When a user tries to perform a domain operation, the master gateway node shuts down.

Multiple gateway nodes

If the domain has multiple gateway nodes and the master gateway node cannot reconnect, then the master gateway node shuts down.
If a user tries to perform a domain operation while the master gateway node is trying to connect, the master gateway node shuts down.
If another gateway node is available, the domain elects a new master gateway node.
The domain attempts to connect to the domain configuration database with each gateway node.
If none of the gateway nodes can connect, the domain shuts down and all domain operations fail.
