Oracle Enterprise Architecture
Performance, Availability, Cost Optimization
Senior Oracle consulting for mission-critical environments where downtime is not an option. From RAC and Data Guard to performance tuning and hybrid PostgreSQL + PMFA deployments.
🎯 Oracle RAC Cluster Architecture
High Availability • Scalability • Zero-Downtime Operations
Scalability
Horizontal scaling by adding nodes to RAC cluster. Handle 10x traffic spikes without vertical scaling limits.
Zero-Downtime
Rolling patches, online node addition/removal. 99.99% uptime guaranteed - maintenance during business hours.
Cache Fusion
Shared cache across nodes with sub-millisecond block transfers. Global SGA coordination for maximum performance.
Cost Optimization
Consolidate multiple single-instance DBs into one RAC cluster. License fewer cores through hard partitioning.
Our Implementation Methodology
Assessment & Planning
- • Current architecture review
- • Performance baseline (AWR/ASH)
- • Licensing audit & optimization
- • ROI calculation & TCO analysis
Design & Deployment
- • RAC cluster design (2-16 nodes)
- • Storage architecture (ASM/NFS)
- • Network tuning (interconnect)
- • Zero-downtime migration plan
Optimization & Support
- • Performance tuning (SQL, indexes)
- • Monitoring setup (OEM, Grafana)
- • Runbooks & operational training
- • 24/7 emergency support option
RAC Is NOT a Silver Bullet
We're honest: RAC won't fix bad SQL. If your app has poorly optimized queries, RAC will just distribute the slowness across more nodes. We always start with performance tuning FIRST (SQL optimization, partitioning, indexing), then add RAC only if you need high availability or horizontal scalability.
Real talk: 70% of "slow database" problems are application-side (bad SQL, N+1 queries, missing indexes). We'll tell you if RAC is the right solution or if you just need performance tuning.
