Oracle Linux-Specific Considerations

• Unbreakable Enterprise Kernel (UEK): Optimized for performance and latest features

• Ksplice: Zero-downtime kernel updates (no reboots required)

• RHEL Compatibility: Binary compatible with RHEL

• Oracle Support: Enterprise-grade support for Oracle workloads

• Free to use: No subscription required for updates

• Oracle Linux 8: Stable, long-term support

• Oracle Linux 9: Latest features, recommended for new deployments

# Or for OL9:
sudo dnf config-manager --enable ol9_baseos_latest ol9_appstream

# Core iSCSI and multipath tools
sudo dnf install -y \

# Check multipath
multipath -ll

# Check services
systemctl status iscsid
