Services in Scope

Three OCI Service Layers — Fully Orchestrated

eAppSys designs DR orchestration across the three OCI service layers that enterprise analytics and data platforms depend on — the analytics tier, the data tier, and the data movement and integration tier — with Object Storage replication and network failover coordinating the whole.

Oracle Analytics Cloud (OAC)

Cross-region OAC snapshot replication to standby Object Storage. Automated OAC pause (primary) and resume (standby) via OCI CLI. OAC snapshot import and restore in the standby region — including Model Admin Tool (RPD) connection reconfiguration and wallet replacement for the standby ADW.

Autonomous Data Warehouse (ADW)

Cross-region ADW standby — automated switchover monitoring until the secondary ADW reaches Available status. Post-failover ADW wallet management and connection reconfiguration in OAC to point to the standby database. Fallback switchover managed on the same automated framework.

Control requirements you can build OCI Data Integration (OCI DI)

Secondary OCI DI workspace activation monitoring — automated status check until Active. OCI DI workspace and application export/import automation using Object Storage as the transfer medium. Project and application import with data asset exclusion to prevent connection conflicts in the standby region.
DR Orchestration Services

Six DR Orchestration Service Areas

eAppSys delivers OCI DR orchestration across six service areas — from multi-region architecture design through to tested SOP documentation and ongoing DR readiness management.

Multi-Region DR Architecture

  • Primary and standby region resource mapping — compute, database, analytics, integration
  • Availability Domain and Fault Domain placement for within-region HA
  • Cross-region replication strategy — Object Storage, ADW standby, OAC snapshots
  • Standby region resource provisioning — equivalent services in inactive state
  • Load balancer design — primary and standby IP configuration for DNS switchover
  • Network topology — VCN peering and connectivity between primary and standby regions

OCI CLI Failover Automation

  • Scripted OCI CLI build job — shell script with environment-specific variable configuration
  • Visual Builder Studio (VB Studio) pipeline deployment for one-click failover execution
  • Alternate Cloud Shell execution path for scenarios where primary VB Studio is unavailable
  • Automated status monitoring loop — continuous polling until all services confirm Active/Available
  • Primary region shutdown automation — OAC pause, OCI DI stop — preventing split-brain and cost
  • Build log output — step-by-step execution tracking for the recovery team

Object Storage Replication

  • Cross-region bucket replication configuration — primary to standby automated replication
  • OAC snapshot storage — timestamped snapshots stored in standby Object Storage
  • OCI DI workspace export storage — automated workspace and application export management
  • Replication validation — confirming standby buckets are current before failover execution
  • Minimal data loss — continuous replication ensures standby data is always current
  • Post-failover primary bucket management during inactive state

DNS & Network Switchover

  • DNS change request process documentation and coordination with network teams
  • Load balancer IP switchover — primary to standby IP for traffic redirection
  • DNS propagation timing expectations — 15 minutes to 4 hours depending on provider
  • Emergency Change Request (ECR) process documentation for network teams
  • Post-switchover traffic validation — confirming all traffic is routing to standby region
  • Fallback DNS reversal — returning traffic to primary on recovery

SOP Design & Documentation

  • Full DR Standard Operating Procedure — Declare Failover . Validate . Fallback
  • Step-by-step runbook with screenshots, decision gates, and alternate paths
  • RACI matrix — clear ownership of each DR step across recovery team roles
  • Escalation path documentation — incident management integration
  • Verification checklist — confirming all services operational post-failover
  • Post-recovery actions register — tasks to complete after successful DR invocation

DR Testing & OracleCloudCare

  • Structured DR test execution — full failover and fallback cycle in a test scenario
  • Test execution report — actual vs target RTO, issues identified, remediation actions
  • Automation script validation — confirming build job executes cleanly in both directions
  • Annual DR test scheduling via OracleCloudCare managed operations
  • Post-update script review — validating automation after OCI service or configuration changes
  • Ongoing DR readiness monitoring — standby region health checks and replication validation

Why eAppSys

Your OCI DR Orchestration Partner

AI and analytics are only as good as the enterprise data beneath them. That data is our home ground.

Scripted — Not Manual

eAppSys implements DR failover as a scripted OCI CLI build job — not a step-by-step manual process. One-click execution in VB Studio, with an alternate Cloud Shell path documented for when the primary infrastructure is unavailable. The automation does the work; the recovery team monitors and validates.

Both Directions — Failover and Fallback

eAppSys designs and tests both directions as first-class scenarios. Failover (primary to standby) and Fallback (standby to primary) are equally scripted, equally tested, and equally documented in the SOP — returning to primary is as reliable as the initial failover.

Tested SOP — Not a Theory Document

eAppSys delivers a DR SOP that has been executed in a test scenario and validated with a test execution report. The recovery team knows the SOP works because it has been run — actual timings, actual issues identified, actual resolution steps documented.

OracleCloudCare — Ongoing Readiness

eAppSys maintains DR readiness through OracleCloudCare — standby region health checks, replication validation, annual DR test scheduling, and post-change script reviews after OCI service updates. DR does not drift after implementation.
Failover Execution Flow

Five Steps from Incident Declaration to Verified Operation

eAppSys designs the DR orchestration SOP around a five-step failover execution flow — matching the structure proven in real-world OCI DR engagements, with both automated and alternate manual paths documented.

01

1 — Declare

Disaster declared; incident raised; recovery team assembled; DNS change request initiated

02

2 — Execute

VB Studio build job triggered; OCI CLI commands execute; ADW, OAC, OCI DI activated in standby

03

3 — Monitor

Automated status loop; build log reviewed; all services confirm Active/Available in standby region

04

4 — Switch DNS

Load balancer IP updated; DNS redirected to standby region; primary region shut down

04

5 — Verify

End-to-end system test; analytics accessible; data pipelines running; OAC snapshot confirmed current

Fallback — Returning to Primary Region
The fallback process mirrors failover in reverse — the same OCI CLI build job is parameterised for the fallback direction, activating primary region resources, replicating any delta data from the standby, reversing DNS, and shutting down the standby region. eAppSys designs both directions as first-class scenarios — failover and fallback are equally scripted, tested, and documented.
Common Questions

Frequently Asked Questions

What is OCI Disaster Recovery Orchestration?
OCI Disaster Recovery Orchestration is the design, scripting, and execution management of automated failover and fallback across Oracle Cloud Infrastructure services — Oracle Analytics Cloud (OAC), Autonomous Data Warehouse (ADW), OCI Data Integration workspaces, and OCI Object Storage. eAppSys designs the multi-region architecture, implements OCI CLI-scripted build jobs for automated execution, configures Object Storage replication, manages DNS switchover coordination, and delivers a tested Standard Operating Procedure for the recovery team.
eAppSys OCI DR orchestration covers: Oracle Analytics Cloud (OAC) — snapshot replication, OAC pause/resume automation, snapshot import and restore on failover, RPD/Model Admin Tool connection reconfiguration; Autonomous Data Warehouse (ADW) — cross-region standby, automated switchover monitoring, wallet and connection management; OCI Data Integration — workspace and application export/import automation, secondary workspace activation; OCI Object Storage — cross-region bucket replication; and DNS and load balancer — IP switchover coordination and Emergency Change Request management.
eAppSys automates OCI DR failover using OCI CLI commands orchestrated through a scripted build job deployed in Oracle Visual Builder Studio (VB Studio). The build job executes a parameterised shell script covering ADW standby activation monitoring, secondary OAC startup, secondary OCI DI workspace activation, Object Storage replication validation, primary region resource shutdown (OAC pause, OCI DI stop), and continuous status monitoring until all components confirm Active or Available in the standby region. An alternate manual path via OCI Cloud Shell is documented for scenarios where the primary VB Studio instance is unavailable.
The automated OCI service failover — ADW standby activation, OAC restart, OCI DI workspace activation, and OAC snapshot restore — can be completed in under 30 minutes. The critical-path variable is the DNS change request to redirect traffic from the primary to standby load balancer IP, which typically takes 15 minutes to 4 hours depending on the network provider’s change management process. Total end-to-end RTO (all services operational, traffic confirmed on standby) is typically 2–3 hours in normal circumstances, validated through a DR test execution report.
eAppSys delivers: OCI multi-region DR architecture design; OCI CLI-scripted failover and fallback build jobs with variable configuration; OAC snapshot replication and import/restore procedures; ADW cross-region standby configuration and wallet management; OCI Object Storage bucket replication; a tested and documented DR Standard Operating Procedure (SOP) covering Declare, Execute, Monitor, DNS Switch, and Verify steps; a DR test execution report with actual vs target RTO; and integration into OracleCloudCare for ongoing DR readiness management and annual DR test scheduling.
