Certainly! Here's an updated version of the Automated BCM Workflow Knowledge Article with a clear explanation that the workflow is task-driven, and includes an approval/control step for the application team before it proceeds with switchover and RPO validation.

Title: Automated BCM Workflow for Oracle Databases
Category: Oracle DBA / Business Continuity
Created On: 23-Jun-2025
Author: [Your Name or Team]
Audience: DB Support, Application Teams, Infra


๐Ÿ”น Purpose

This article outlines the automated BCM (Business Continuity Management) process for Oracle databases. It provides a task-driven, controlled workflow for switching roles between Primary and Standby databases. Users initiate BCM through a ticket, and the system handles validations, evidence gathering, and controlled execution.


๐Ÿ”น Key Feature: Task-Driven Workflow with User Control

The BCM automation follows a multi-stage workflow, which gives explicit control to the application team. After the ticket is raised:

  • The workflow creates a task for the application team to confirm readiness.
  • The switchover will not proceed automatically until the app team completes and closes the task.
  • Once the task is closed:
    • The workflow proceeds to gather RPO evidence (replication status, lag checks).
    • Then it executes the switchover or failover in a controlled, auditable manner.

This ensures collaboration, traceability, and accountability between DB and application teams.


๐Ÿ”น Prerequisites for Requesting BCM

Requirement Details
๐ŸŽซ Service Ticket Must be raised in ITSM system with all required fields
๐Ÿ“Œ Correct Database Info Ensure accurate DB name, primary host, standby host
Healthy Replication Archive logs applied without significant lag
๐Ÿ“ก Connectivity Ensure listener & SQLNet connectivity between primary and standby
๐Ÿงพ Application Team Readiness Confirmed via automated task in workflow
๐Ÿ” Business Approval Required for production; attach approval thread/email

๐Ÿ”น Workflow Overview

flowchart TD
    A[User Raises Ticket] --> B[Workflow Validates Inputs]
    B --> C[Create Task for App Team]
    C --> D[Wait for Task Closure]
    D --> E{Task Closed?}
    E -- No --> F[Wait / Notify SLA Breach]
    E -- Yes --> G[Gather RPO & Replication Evidence]
    G --> H[Execute Switchover/Failover]
    H --> I[Post-Check and Update Ticket]

๐Ÿ”น What Happens After Task is Closed?

Once the application team marks the task as completed/closed:

  1. ๐Ÿงช RPO Evidence Collection:

    • Archive log apply lag
    • Standby sync status
    • Timestamp comparison between primary & standby
  2. ๐Ÿ” Switchover Execution:

    • Via dgmgrl switchover or patronictl switchover
    • Optional pre-checks: listener, TNS, DB roles
  3. ๐Ÿ“‹ Post-Checks:

    • Role confirmation (Primary/Standby)
    • Application connectivity verification (optional)
    • Ticket updates with timestamps and summary

๐Ÿ”น Ticket Template (Mandatory Fields)

Field Sample
Request Type BCM – Oracle Switchover
DB Name ORCLPRD
Primary Host db1.prod.local
Standby Host db2.dr.local
Business Approval Attached
Preferred Window 10 PM – 12 AM SGT

๐Ÿ”น Notes

  • For Planned Switchover, raise the request at least 24 hours in advance.
  • For Unplanned Failover, automation proceeds faster but still creates a task for audit.
  • SLA for App team task completion may be enforced in future versions.

๐Ÿ”น Benefits of This Approach

✅ Ensures application team involvement and readiness
✅ Automates technical checks, RPO validation, and switch execution
✅ Reduces manual errors and ensures auditability
✅ Integrates into your ITSM system with ticket/task traceability
