OS — Oracle Linux
Oracle Linux
The operating system Oracle develops and tests its databases on. There is no more natural home for a database server — and we deploy, secure and tune it precisely for your workload.
Why Oracle Linux under an Oracle database
No licence fees
Oracle Linux is free, updates included — you pay only for support if you want it. Binary compatible with RHEL.
UEK — a kernel tuned for Oracle
The Unbreakable Enterprise Kernel is optimised specifically for database workloads and modern storage.
Ksplice — patches without reboots
Kernel security patches applied live. The database server keeps running — and stays current.
One vendor, one path
OS and database from the same vendor: preinstall packages, tested combinations, no compatibility guesswork.
OS and database installation
We build the whole database server from bare metal (or VM/cloud) to a running, documented database — one supplier, no responsibility ping-pong.
- Oracle Linux installation — physical servers, virtualisation, cloud
- OS preparation for the database: preinstall RPM, kernel parameters, limits
- Hugepages, NUMA and memory configuration for large SGAs
- Storage layout design, ASM, multipathing, udev rules
- Oracle Database installation — single instance and Grid Infrastructure / RAC
- Full documentation — a server you can take over with no question marks
System hardening
A database is only as secure as the system it runs on. We harden servers systematically, following recognised guidance — not "disable SELinux and move on".
- Hardening along CIS benchmarks, minimal installation footprint
- SELinux configured properly — enabled, not bypassed
- Firewalling and segmentation: access only from where it belongs
- Ksplice / dnf automation for security updates
- Key-based SSH access, auditing of privileged operations
- Regular compliance checks against the security baseline
Tuning the OS for database workloads
The difference between an "installed" and a "tuned" server shows up in latencies and in the hardware bill. We configure the system around the database's real workload profile.
- I/O scheduler and storage parameters per disk type
- Network tuning for RAC interconnect and application peaks
- Transparent HugePages off, classic hugepages sized correctly
- OS metrics wired into the database monitoring stack
Planning a new database server?
We will design it from the OS up to the database — or assess and fine-tune the one you already run.
