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 […]
In this article, we will see how to convert an existing Physical Standby Database into an Active Data Guard configuration in Oracle 19c. The read-only physical standby database can be used to offload reporting and query workloads from the primary database. Users can execute SELECT statements and complex analytical queries on the standby, thereby reducing […]
Keeping a standby database synchronized with its primary is critical for fast failover, reporting offload, and disaster recovery readiness. When archived redo transfer is slow, missing, or the standby has fallen behind significantly, an SCN-based incremental RMAN refresh is a fast, reliable way to bring the standby forward. This article provides a clear, step-by-step operational […]
This procedural article describes configuring a Snapshot Standby (Data Guard) and exercising the convert-to-snapshot / convert-back lifecycle. Follow the steps precisely and validate each checkpoint in your environment before proceeding. Step 1 — Verify roles on Primary and Standby On Primary: Sample output (Primary): On Standby: Sample output (Standby): Step 2 — Confirm archived log […]
