Oracle Linux Support: Premier, Basic & Contact Options

Teams comparing Oracle contracts against outside Oracle Linux server support face an unusual model: the operating system and its updates are free, and the paid subscription buys support services on top. Oracle Linux Basic, Premier, and Premier Plus are priced per physical CPU pair per year, with published list prices. This page lays out what is free, what each paid tier adds, how to contact Oracle support, and the lifecycle windows per release.

The free layer: OS and updates without a subscription

Oracle Linux is free to download, use, and distribute under GPLv2. Unlike Red Hat Enterprise Linux, updates are also free: Oracle publishes security updates and bug-fix errata on the public Oracle Linux yum server with no subscription, registration, or entitlement key required. Oracle's own Oracle Linux FAQ states that updates and errata are freely available, excluding items tied to paid offerings — Ksplice patches and Extended Support errata require a subscription.

The practical consequence: a fleet can run fully patched Oracle Linux at zero license cost. What a paid subscription adds is not update access but support services — a break/fix channel, indemnification, zero-downtime patching, and access to the Unbreakable Linux Network (ULN) and My Oracle Support.

Paid tiers: Basic, Premier, Premier Plus

Oracle's Linux Support page and the Oracle Linux Support Global Price List (dated July 1, 2026) define three tiers, all priced per physical CPU pair per year. A multi-core or hyperthreaded chip counts as one physical CPU; a two-socket server is one CPU pair. Systems with more than two physical CPUs require stacked subscriptions — one per additional CPU pair.

Note on naming: "Premier Limited" appears on the current price list only as an Oracle VM support tier ($599/system for hosts with up to 2 physical CPUs), not as an Oracle Linux tier. The current Oracle Linux lineup is Basic, Premier, and Premier Plus. All prices above are Oracle's published US list prices; contracted pricing may differ, and volume terms are quote-based through Oracle sales.

Ksplice: the Premier differentiator

Ksplice applies kernel, hypervisor, and select user-space (glibc, openssl) security patches to a running system without a reboot. It requires a Premier or Premier Plus subscription and works with both the Unbreakable Enterprise Kernel (UEK) and the Red Hat compatible kernel. It also includes known-exploit detection, which flags and can block attempts against select patched privilege-escalation vulnerabilities. Usage is documented in the Ksplice User's Guide on docs.oracle.com. For environments with strict uptime requirements, Ksplice is the main technical argument for Premier over Basic.

How to contact Oracle Linux support

• Portal. Service requests are filed through My Oracle Support at support.oracle.com. A valid Customer Support Identifier (CSI) from an active subscription is required to register and open cases.
• Phone. Oracle's Global Customer Support directory lists 1.800.223.1711 for the United States, with separate numbers per country. The phone line is also the fallback during a My Oracle Support portal outage.
• Severity levels. Cases are classified Severity 1 through 4 under Oracle's technical support policies. Severity 1 (complete loss of service in production) is worked continuously with 24x7 effort, and Oracle expects the customer to provide a contact around the clock while a Severity 1 case is open. Lower severities are handled during normal support hours. Oracle publishes definitions in its Software Technical Support Policies document rather than fixed response-minute guarantees per tier.

Coverage for RHEL and legacy CentOS installations

An Oracle Linux support subscription can be applied to existing RHEL and legacy CentOS Linux installations without reinstalling the operating system. Per the Oracle Linux FAQ: coverage extends to legacy CentOS (not CentOS Stream), is limited to packages and versions present on Oracle Linux installation media, and all errata delivered are Oracle Linux binaries, which are RHEL-compatible. Servers register against ULN with a CSI and pull updates from there. Oracle also publishes a conversion script for switching legacy CentOS or Rocky Linux installs to Oracle Linux in place. Organizations with an active Red Hat contract should check its terms before routing support for those systems to Oracle.

Lifecycle windows per release

Premier-level support runs ten years from a release's GA date, per Oracle's Lifetime Support Policy for open source offerings. Extended Support adds roughly three further years at an uplift (10% of the Premier subscription in year one, 20% in subsequent years, per the price list), followed by indefinite Sustaining Support without new errata.

Confirm dates for other releases against the lifetime support policy document before planning migrations; Oracle updates it periodically.

When third-party or managed support fits

Oracle's subscription is priced and structured around Oracle's stack — it pairs naturally with Oracle Database, OCI, and UEK-dependent features. It fits less well in two common situations:

• No Oracle stack. A shop running Oracle Linux purely as a free RHEL-compatible base, with no Oracle Database or OCI footprint, gets updates free from yum.oracle.com and may only need operational help: incident response, patch execution, performance troubleshooting, hardening. A managed provider covers that layer without a per-CPU-pair Oracle contract.
• Mixed fleets. Estates that combine Oracle Linux with Ubuntu, Debian, AlmaLinux, or RHEL end up with one support contract per distribution under the vendor model. A single provider covering the whole fleet consolidates that.

Medha Cloud provides Linux server support across Oracle Linux, RHEL-family, and Debian-family distributions, with 24/7 engineer availability by chat and phone. Background on the distribution itself is covered in Oracle Linux, and vendor support lines for other distributions are listed in Linux server support numbers.

FAQ

Is Oracle Linux really free, including updates?

Yes. The OS is GPLv2, and security errata and bug fixes are published free on yum.oracle.com. Exceptions are Ksplice live patches and Extended Support errata, which require a paid subscription.

What is the Oracle Linux support phone number?

1.800.223.1711 in the United States, per Oracle's Global Customer Support directory at oracle.com/support/contact.html. Cases normally go through the My Oracle Support portal at support.oracle.com; the phone line requires an active CSI.

How much does Oracle Linux Premier Support cost?

US list price is $1,399 per physical CPU pair per year on the July 2026 price list. Basic is $699 and Premier Plus is $2,499 on the same metric. Systems with more than two physical CPUs need one subscription per CPU pair.

Does Oracle support CentOS or RHEL servers?

Yes, within limits. An Oracle Linux subscription can cover existing RHEL and legacy CentOS installations (not CentOS Stream), with errata delivered as RHEL-compatible Oracle Linux binaries via ULN. No OS reinstall is required.
