Fault Tolerance
A fault tolerant environment is similar to a migration environment but includes additional features to ensure uninterrupted operation even after the failure of a component. A fault tolerant environment ensures network connections, continuous service, and data access through synchronized shared storage. If a component switch occurs, client machines and applications continue to function normally with no database engine interruption.
Pervasive PSQL Vx Server is the preferred product for fault tolerant environments for the same reason as discussed in Migration.
No special steps are required to install or configure Pervasive PSQL in a fault tolerant environment. Refer to the hypervisor documentation.
