WAY4 Auto Switchover is a new component of WAY4 High Availability Cluster. It detects unavailability of a primary node and automatically switches the system to the secondary node. Switching is completed within 15-30 seconds. The monitoring and switching algorithm depends on predefined rules that can be extended and customized. Examples of such rules:
No connection with a node, connection attempt terminates with an error or takes longer than a timeout
Connection errors that cannot be eliminated by repeated attempts (‘invalid username or password’, ‘account is locked’, ‘restricted session’, ‘Oracle is not available’, etc.)
Insufficient space in a tablespace
The solution has been already proven in live environment operations.
