This capability unlocks accelerated provisioning pipelines for development, testing, QA refreshes, and rapid environment replication—while keeping production workloads uninterrupted. […]
A standby database is a transactionally consistent copy of the production database. It enables the production Oracle database to survive disasters and data corruption. When the production database becomes unavailable due to a planned or unplanned outage, Data Guard can promote a standby database to the primary role, minimizing downtime. In addition, performance of the […]
