Oracle ExaCC licensing. Billed by OCPU.

Oracle Exadata Cloud at Customer puts Exadata hardware in your data center but bills it as a cloud service by OCPU, so the cost lever shifts from processor licenses to scaling discipline and your Bring Your Own License position.

This guide is for Oracle license managers and infrastructure leaders sizing an ExaCC deal in 2026. Read it alongside the Oracle licensing pillar and the Oracle Practice page so the metric and the negotiation stay aligned.

How is Oracle ExaCC actually licensed?

ExaCC keeps Exadata in your data center but shifts billing to a cloud consumption model. You pay for compute by the OCPU per hour, and the database itself comes either license included or under Bring Your Own License.

What is an OCPU and why does it matter?

An OCPU is Oracle's compute unit, roughly one physical core with hyper threading. ExaCC charges by the OCPU you have provisioned, not the OCPU you use, so an idle but provisioned core still bills. Oracle documents the model on its cloud price list.

• License included: the cloud rate bundles the database license into the OCPU price.
• Bring Your Own License: you apply perpetual licenses and pay a lower cloud rate.
• Storage and options: billed separately from the OCPU compute line.

When does Bring Your Own License pay off?

BYOL pays off when you already own perpetual Database Enterprise Edition and the options the workload needs. The cloud rate drops sharply, but support on the perpetual licenses continues, so the net saving depends on your support base.

What actually drives the ExaCC bill?

The bill is driven by provisioned OCPUs, the options you enable, and how disciplined you are about scaling down. Hardware is fixed once installed, so the variable cost is almost entirely the OCPU line.

Why does OCPU scaling discipline matter so much?

ExaCC lets you scale OCPUs up and down online. Teams scale up for a peak and rarely scale back. That idle headroom is the single most common source of ExaCC overspend we see.

How do database options inflate the cost?

Options such as partitioning, multitenant, and in memory bill per OCPU. Enabling an option across the full rack when only one database needs it multiplies the cost. License the option to the workload, not the hardware.

1. Map options to databases: list which database actually uses each option.
2. Cap OCPUs per workload: set a provisioned ceiling and review it monthly.
3. Reconcile BYOL: match perpetual licenses to the OCPUs claiming the lower rate.

What to do next

1. Pull the current provisioned OCPU count per ExaCC database.
2. Compare provisioned OCPUs against peak and steady state demand.
3. List every enabled database option and the databases that use it.
4. Confirm which perpetual licenses back any BYOL OCPUs.
5. Model license included against BYOL for each workload.
6. Set a monthly scale down review owned by a named person.
7. Fold the ExaCC rate into your wider Universal Credits negotiation.

Frequently asked questions

What is Oracle Exadata Cloud at Customer?

Exadata Cloud at Customer, or ExaCC, is Oracle Exadata hardware installed in your own data center but operated as a cloud service by Oracle. You consume it with cloud metering while the machine sits behind your firewall.

How is ExaCC licensed and billed?

ExaCC bills through Oracle Cloud credits by OCPU per hour, with database options layered on top. You can bring existing database licenses under Bring Your Own License or pay the license included rate per OCPU.

Does Bring Your Own License save money on ExaCC?

It can, when you already hold perpetual Database Enterprise Edition and option licenses. BYOL drops the cloud rate sharply, but you still owe annual support on the perpetual licenses, so the net depends on your support base.

What are the common ExaCC cost traps?

The frequent traps are scaling OCPUs up and forgetting to scale down, paying license included rates while holding unused perpetual licenses, and licensing every enabled database option across the whole rack rather than per workload.

How does ExaCC differ from Exadata on premises?

On premises Exadata is a capital purchase you license by processor. ExaCC keeps the same hardware in your room but shifts you to a cloud consumption model, so the lever moves from license counts to OCPU scaling discipline.

Can you negotiate ExaCC pricing?

Yes. The committed consumption rate, the BYOL discount, and the OCPU floor are all negotiable, especially when ExaCC sits inside a larger Oracle Universal Credits commitment.
