A Recurring Capital Sink With No Endpoint
The business was approaching its third on-premises hardware refresh in under ten years, each cycle consuming budget that never translated into new capability — only continuity of the status quo.

Retiring the hardware refresh cycle with OCI Autonomous Database
A discrete manufacturing company was staring down its third consecutive on-premises Oracle hardware refresh in under a decade, with no disaster recovery site to show for the investment. OptiSol re-architected the environment onto OCI Autonomous Database with built-in Data Guard-based DR, ending the refresh cycle and adding resilience the on-premises setup never had.

The Challenge
A Third Hardware Refresh, and Still No Disaster Recovery Site
The company's Oracle database underpinned production scheduling, inventory, and supply-chain visibility across its plant floor, yet every capital cycle went toward keeping the same on-premises architecture alive rather than making it more resilient.
No Disaster Recovery Site at Any Point
Despite three hardware generations, the company had never budgeted for a secondary site, leaving production scheduling and inventory systems with a single point of failure the whole time.
Manual Tuning Couldn't Keep Pace With Plant Growth
New production lines and expanded supply-chain integrations kept adding load, and DBA time increasingly went to manual performance tuning rather than the improvements the business actually needed.
The Approach
A Cloud-Native Re-Architecture, Not Another Lift-and-Shift
Rather than recommend a fourth hardware refresh or a like-for-like cloud VM migration, OptiSol proposed re-architecting onto OCI Autonomous Database — moving the DR and tuning burden into the platform itself.
Cloud Readiness Assessment
OptiSol profiled the Oracle estate against AWR and Statspack history spanning multiple production cycles, identifying which workloads were strong Autonomous Database candidates and which custom PL/SQL objects needed remediation first.
Autonomous Database & Data Guard DR Design
The target architecture paired OCI Autonomous Database with a Data Guard standby in a second OCI region, giving the company a tested disaster recovery posture from day one instead of an afterthought bolted on later.
Staged Migration via OCI Database Migration and RMAN
OCI Database Migration handled schema and metadata conversion while an RMAN-based backup restore populated the Autonomous Database target, validated against row counts and checksums before any cutover planning began.
Data Guard Switchover Rehearsal
The team rehearsed a full Data Guard switchover to the standby region twice before go-live, confirming production scheduling and inventory applications could reconnect automatically without manual DNS or connection-string changes.
30-Day Post-Migration Validation
Performance was benchmarked against the pre-migration AWR baseline for 30 days after cutover, with Autonomous Database's built-in auto-tuning changes tracked separately to confirm they were net improvements, not just different plans.
Hardware Refresh Cycle Eliminated Going Forward
Moving to OCI Autonomous Database removed the recurring on-premises refresh the company had budgeted for every few years, converting a capital expense pattern into a predictable operating cost.
Disaster Recovery the Company Never Had
The Data Guard standby in a second OCI region gave the business its first real cross-region DR site, an estimated improvement from effectively zero recovery capability to a tested, automatable failover path.
DBA Time Redirected From Tuning to the Business
Autonomous Database's self-tuning and self-patching capabilities typically remove a large share of routine index and statistics maintenance, freeing the DBA team to work on supply-chain integration projects instead.
Elastic Capacity for Plant Growth
Autonomous Database's independent compute and storage scaling let new production lines and supply-chain integrations add load without the manual capacity planning the on-premises hardware previously required.
The Impact
The Business Impact
- Recurring on-premises hardware refresh cycle eliminated entirely
- First cross-region disaster recovery site established via Data Guard on OCI
- Full Data Guard switchover rehearsed and validated twice before go-live
- 30-day AWR-baseline performance validation completed with no unresolved regressions
- Routine tuning and patching workload substantially reduced through Autonomous Database automation
- New production lines and integrations now scaled without manual capacity workarounds
We stopped asking 'can we afford the next hardware refresh' and started asking what our DBA team should actually be building. That's the real shift Autonomous Database made possible." — OptiSol Oracle Engineering Lead
