Oracle Exadata Cloud at Customer: A Detailed Exploration
Oracle Exadata Cloud at Customer, known to the tech-savvy as ExaC@C, is a unique offering in database services. It’s part of the more extensive Oracle Cloud Infrastructure, providing autonomous and co-managed Oracle Database solutions.
The essence of this service lies in its perfect blend of customer control and Oracle management.
What’s in the Exadata C@C Box?
When you delve into Oracle Exadata Cloud at Customer, you uncover a treasure trove of features:
- Integrated system: ExaC@C integrates the prowess of Oracle Exadata and Oracle Cloud Infrastructure. It brings this stellar combination right into your data center while Oracle retains the responsibility of managing the Exadata infrastructure.
- Performance and scalability: You get full access to Oracle Database features and the remarkable performance and scalability of Oracle Exadata.
- Manageable through Oracle Cloud Infrastructure console: The management of ExaC@C is akin to other cloud resources. You can use Oracle Cloud Infrastructure’s console and APIs, maintaining total sovereignty over your data.
Breaking Down the Exadata Technical Architecture
Delving deeper into the technical architecture of ExaC@C, it is constituted of several interconnected components:
- Oracle Exadata Database Servers and Storage Servers are interconnected via a high-speed, low-latency RDMA fabric network and intelligent Oracle Exadata software.
- Virtual Machine Technology: This separates the customer-managed and Oracle-managed components on each database server. While you have root privilege for the Exadata database server VMs, the physical database server hardware is administered by Oracle.
- Oracle Exadata Storage Servers: These servers handle database storage, allocated to disk groups managed by Oracle Automatic Storage Management (Oracle ASM). You have full admin access to Oracle ASM disk groups, while Oracle manages the Exadata Storage Server hardware and software.
Additional Infrastructure Components Managed by Oracle
In addition to the database server hardware and Exadata Storage Servers, Oracle manages other infrastructure components of ExaC@C. This includes network switches, power distribution units (PDUs), and integrated lights-out management (ILOM) interfaces.
What is Oracle Exadata?
Oracle Exadata is a database machine, an integrated system designed by Oracle Corporation. It is primarily intended to host Oracle Database and aims to deliver optimized performance, scalability, and reliability compared to traditional database deployment methods.
It’s worth noting that Oracle Exadata is not a standalone database. Instead, it’s a combination of hardware and software that works in unison to enhance the capabilities of the Oracle Database.
It includes a blend of servers, storage, networking, and software, all optimized to work together seamlessly.
While Oracle Exadata is widely recognized for its high performance and efficiency, it’s essential to understand that these benefits depend on various factors, including specific workloads, configurations, and management practices.
Like any technological solution, its effectiveness ultimately hinges on its alignment with the specific needs and context of the organization using it.

Oracle Exadata Cloud at Customer: Supported Database Editions and Versions
Oracle Exadata Cloud at Customer extends support to various Oracle Database software releases. Here’s the rundown of what’s compatible:
- Oracle Database 19c (19. x): Fully supported with ExaC@C.
- Oracle Database 12c Release 2 (22.214.171.124): Supported for approved customers only, making it a selectively available option.
- Oracle Database 12c Release 1 (126.96.36.199): Supported, but with a catch. If you create or update a 188.8.131.52 database with an RU later than July 2022, you need a valid Market Driven Support (MDS) contract.
- Oracle Database 11g Release 2 (184.108.40.206): This version is supported, but if you’re creating or updating an 220.127.116.11 database with a PSU later than April 2021, you also need a valid MDS contract.
Exadata Cloud at Customer: Pros and Cons
Oracle’s Exadata Cloud at Customer (ExaCC) brings the power of Exadata into your data center. With this solution, Oracle deploys and manages the infrastructure, including monitoring, patching, and troubleshooting, right on your premises.
This setup provides access to Oracle Cloud service offerings with the underlying infrastructure running on Exadata on-site.
To further understand the potential advantages and drawbacks of ExaCC, let’s break them down:
|Colocation: ExaCC meets business requirements that mandate data to reside on a company’s premises, catering to needs for low latency connections or regulatory requirements.||Lock-in: Customers must commit to a minimum four-year contract with Oracle to provide on-site hardware.|
|Autonomous Database: Oracle’s Autonomous database, a service offered on Oracle Cloud, can be deployed using ExaCC.||Lock-in: Customers must commit to a minimum four-year contract with Oracle to provision the hardware on-site.|
|Reduced Capital Expenditure: Since Oracle owns the Exadata systems with ExaCC, the customer pays a subscription for the service used, potentially reducing costs compared to owning and managing Exadata on-site.||Availability: While on-premises Exadata systems have built-in redundancy, they cannot match the high availability of Exadata systems deployed on Oracle’s public cloud.|
|Service Encapsulation: Oracle remotely patches hardware components in a rolling fashion, preserving service availability throughout the updating process.||Costing Strategy: Customers pay a fixed monthly payment for Exadata infrastructure usage, plus payments for hourly OCPU consumption, which might result in a larger bill compared to an ExaCS deployment.|
