Cross-referenced all 70+ KB files against official Oracle docs. Critical fixes: - ExaCS: storage was flash cache not usable disk (76.8→190.8 TB QR), added X11M, removed X10M - ADB-S: OCPU→ECPU migration, 26ai as default, cross-region RTO 15→10 min - Compute: E5 max 94→126, A2 80→78, added E6/A4/BM shapes, 11 GPU shapes - Storage: Higher Perf IOPS 35K→50K, UHP 450K→300K, File Storage 25K→50K - DBCS: E5.Flex max 94→64, storage 80→150 TB, added 26ai - Networking: FastConnect +400 Gbps, NSG max 120 rules Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

what: Oracle Database on VM or Bare Metal in OCI. Full DBA control with
|
|
automated provisioning and backup. Available as single-instance or 2-node RAC.
|
|
|
|
editions:
|
|
- Standard Edition
|
|
- Enterprise Edition
|
|
- Enterprise Edition High Performance
|
|
- Enterprise Edition Extreme Performance
|
|
|
|
when_to_use:
|
|
- Standard Edition workloads (ADB requires EE)
|
|
- Need full OS and database control without Exadata
|
|
- Moderate workloads that don't need Exadata performance
|
|
- Budget-conscious deployments where Exadata is over-provisioned
|
|
- Development and test environments mirroring production DB config
|
|
- Applications requiring specific Oracle versions or patches
|
|
|
|
when_NOT_to_use:
|
|
- High-performance OLTP (Exadata or ADB better)
|
|
- Variable workloads benefiting from auto-scaling (use ADB-S)
|
|
- No DBA team available (use ADB-S)
|
|
- Need Exadata features (Smart Scan, HCC, Flash Cache)

gotchas:
|
|
- id: DBCS-001
|
|
issue: "2-node RAC is maximum on VM shapes"
|
|
impact: "Cannot scale RAC beyond 2 nodes (use ExaCS for more)"
|
|
recommendation: "If >2 RAC nodes needed, evaluate ExaCS"
|
|
- id: DBCS-002
|
|
issue: "Performance limited by block storage"
|
|
impact: "Cannot match Exadata IOPS/latency"
|
|
recommendation: "Use higher performance block volumes or move to ExaCS for I/O intensive workloads"
