the Way Oracle Designed Them to Run. AWS and Azure run Oracle databases on general-purpose hardware at Oracle list prices. OCI runs them on Exadata — the hardware Oracle builds specifically for Oracle databases — at 40–60% lower licence cost, with Smart Scan and storage offload features that reduce query time by an order of magnitude for large Oracle Fusion workloads. Symhas migrates Oracle databases to OCI Exadata Cloud Service using Oracle Zero Downtime Migration — no outage window, no data loss, and a tested rollback plan before the cutover begins. BYOL licence position reviewed and optimised before the first resource is provisioned.
Production-Grade from Day One.
Every capability designed, deployed, and documented by Symhas OCI-certified architects. Fixed price. Fixed timeline. SLA-backed from go-live.
Four Phases. Fixed Price.
Go/no-go gates at every phase. Scope and price agreed before week one. No surprises at handover.
Full Oracle database inventory — versions, sizes, features in use. BYOL licence position reviewed and optimised. Exadata shape sizing based on workload profiling. ZDM migration method selected. Migration wave plan agreed.
Exadata CS provisioned and configured. IORM and Smart Scan configured. ZDM toolkit installed and source-to-target connectivity validated. Pre-migration checklist completed. Non-production databases migrated first.
Production databases migrated using ZDM with redo apply running. Performance benchmarked against pre-migration baseline. Data Guard standby configured and lag validated. Cutover rehearsal completed in non-production.
Production cutover executed — ZDM switchover under 60 seconds. Source databases placed in read-only for 24-hour validation period. Data Guard DR test completed within 2 weeks of go-live. Source decommission approved.
6-Hour Batch to 38 Minutes. Zero Downtime. OCI Exadata CS.
A global asset management firm was running Oracle Fusion Finance on AWS RDS — paying AWS Oracle Database licence rates and experiencing a 6-hour Oracle month-end batch processing window that delayed financial close. The Oracle Performance team had identified Exadata as the solution but AWS does not offer Exadata.
Symhas migrated 6 Oracle databases to OCI Exadata Cloud Service using Oracle Zero Downtime Migration — zero unplanned downtime during migration, Oracle Fusion Finance month-end batch reduced from 6 hours to 38 minutes, and Oracle Database licence cost reduced by 43% through BYOL optimisation on OCI.
Oracle Database Migration to OCI Exadata CS — Financial Services
“The Oracle Fusion Finance month-end batch ran in 38 minutes. It had never run in under 4 hours in 8 years of operation. Exadata is not a marginal improvement — it is a different class of database infrastructure.”
— CTO, Global Asset Management Firm
We Configure for This Capability.
Oracle Exadata hardware in OCI — Smart Scan, IORM, flash cache, and Hybrid Columnar Compression for Oracle database workloads.
ZDM toolkit — physical and logical migration with continuous redo apply and sub-minute cutover window.
Serverless Oracle databases for analytics and development — self-patching, self-tuning, and auto-scaling.
Real-time database replication for DR — Active Data Guard, Far Sync zero-data-loss, and automated failover.
Database backup to OCI Object Storage — policy-driven, encrypted, and cross-region replicated.
Oracle Database licence review — identifying unused options, optimising BYOL position on OCI, and reducing annual licence spend.
The OCI tenancy, IAM, and network foundation that Oracle databases run on — built before the first database is migrated.
Cloud Guard, Vault, and Security Zones protecting the Oracle databases and Fusion applications running on OCI.
24x7 monitoring and incident response covering the Oracle databases and Fusion workloads running on OCI Exadata.
We Will Model the Exadata Performance and Cost Case. A 30-minute Oracle Database assessment with a Symhas OCI architect. We will review your current database workloads, BYOL licence position, and migration complexity — and produce an Exadata sizing and cost model before the engagement begins. No commitment. No pitch deck. An honest conversation about your OCI environment.
