All tests performed on both Intel and AMD platforms, OCP 4.18 or above.
Testing is performed with different storage configurations, such as:

• ODF (Block)
• SAN (Block) iSCSI
• SAN (Block) FC

3. Detailed Implementation Guides

Select the specific configuration below for deep-dive technical requirements (Networking, YAML snippets, and Tuning):

A. Oracle 19c Single Instance

• Storage: ODF via RBD (Block mode)
• Key Tuning: HugePages (2MB), VirtIO-SCSI multiqueue.
• Additional Details: Oracle Database Workloads On OpenShift Virtualization Reference Architecture

B. Oracle 19c RAC (Real Application Clusters)

• Interconnect: Secondary Networks via Multus (SR-IOV recommended).
• Shared Storage: Requires ReadWriteMany (RWX) Block volumes.
• Additional Details: Oracle Database Workloads On OpenShift Virtualization Reference Architecture

C. Oracle 26ai Installation, RAC Setup, and Migration Guide from 19c

• Reference for Single Instance installations, RAC deployments, database migrations, and performance tuning on RHEL / Oracle Linux.
• Additional Details: Comprehensive reference Oracle 26ai

4. Tuning Best Practices

• Production-compliant performance improvements derived from HammerDB benchmarking on Single Instance and Oracle RAC instances on OCP Virtualization.
• Additional Details: Oracle Database Performance Tuning Best Practices for OCP-V

5. Known Issues and Limits

• MTU Settings: Ensure consistent MTU (9000 recommended) across the RAC private interconnect.
• IOPS Limits: Review default QEMU disk throttling if performance fluctuates.
