This article outlines the automated process for BCM (Business Continuity Management) in Oracle databases. It enables controlled and validated switchover or failover operations between Primary and Standby environments using an internal automation framework. Users are expected to follow the procedure to initiate BCM safely.

🔹 Scope

• Oracle Database (Version 12c and above)
• Applies to all environments configured with Primary–Standby setup
• Only for databases registered in the automation system

   • Must match with inventory/CMDB

2. Primary–Standby Pairing

   • Checks hostname-to-database mapping

3. Replication Health

   • Zero or tolerable lag
   • Archive logs applied within last few minutes

4. Listener + SQLNet Reachability

   • Basic `tnsping
