What is Oracle Coherence?
Oracle Coherence is a distributed data grid solution that allows organizations to predictably scale mission-critical applications by providing fast and reliable access to frequently used data. It enables organizations to push data closer to the application for faster access and greater resource utilization.
By automatically and dynamically partitioning data, Oracle Coherence ensures continuous data availability and transactional integrity, even in a server or site failure.
Oracle Coherence Editions
Oracle Coherence is available in three editions:
- Oracle Coherence Standard Edition One (OC-SEO): This edition allows unlimited nodes in a cluster, but only two nodes can be configured to have any partitioned cache services.
- Oracle Coherence Enterprise Edition (OC-EE): This edition provides advanced features for data grid applications, including data query and aggregation, data replication services, and data partitioning services.
- Oracle Coherence Grid Edition (OC-GE): This is the most feature-rich edition of Oracle Coherence, providing all the capabilities of the Enterprise Edition plus real-time data analysis, in-memory data processing, and continuous data availability.
Each edition of Oracle Coherence includes unlimited Oracle Coherence Real-Time Data Clients licenses, providing Java client access from within the Coherence cluster.

Footnotes:
- Coherence Multitenancy works only in conjunction with Oracle WebLogic Server Multitenant. See Oracle WebLogic Server Multitenant for additional licensing details.
- Grid Edition is required for Federated Caching, WAN, and other deployments that implement cluster-to-cluster interconnects, including any deployment where responsibility for data and/or processing spans more than one data center, and activities are coordinated between those data centers using any form of Coherence-provided messaging or connectivity, such as deployments that feature two or more TCMP clusters interconnected by Coherence*Extend.
Oracle Coherence Licensing Metrics
Oracle Coherence licensing is based on two metrics:
- Named User Plus: This metric is defined as an individual authorized by you to use the programs installed on a single server or multiple servers, regardless of whether the individual is actively using the programs at any given time. A non-human operated device will be counted as a named user plus in addition to all individuals authorized to use the programs if such devices can access the programs.
- Processor: This metric defines all processors where the Oracle programs are installed and/or running.
Oracle Coherence License Costs
The cost of Oracle Coherence licensing is as follows:
- Coherence Standard Edition One (OC-SEO):
- Named User Plus License: $16.00
- Software Update License & Support for Named User Plus: $3.52
- Processor License: $800.00
- Software Update License & Support for Processor: $176.00
- Coherence Enterprise Edition (OC-EE):

You can indeed be using the product. But in our experience, Coherence has been installed as part of the fusion middleware installer. You should understand if you can avoid installing Coherence if you are not using it. If you are unable not to install Coherence, document this fact.
Coherence Community Edition – What is it?
Coherence Community Edition (CE) is a free and open-source edition of Oracle Coherence, a market-leading in-memory data grid. It provides a reliable and scalable platform for state management and polyglot processing on the data grid.
Cost
As an open-source edition, Coherence CE is free of charge. This makes it an accessible choice for organizations looking to leverage the capabilities of an in-memory data grid without the associated costs of commercial software.
How it Differs from Other Editions
Coherence CE differs from other editions of Coherence in several ways:
- Licensing: Coherence CE is licensed under the Open Source Initiative’s Universal Permissive License, Version 1.0. This means it’s free to use for any purpose, unlike the Enterprise edition, which requires a paid license.
- Features: While Coherence CE provides a reliable and scalable platform for state management and polyglot processing on the data grid, some advanced features in the Enterprise edition may not be included in the Community edition.
- Community Support: As an open-source project, Coherence CE benefits from a community of developers who contribute to its development and offer support to other users. This contrasts with the Enterprise edition with Oracle’s official support.
- Integration: Coherence CE can be integrated with other systems through Coherence*Extend, allowing each cluster to act as a Data Client or a Real-Time Client.
In summary, Coherence Community Edition offers a cost-effective solution for organizations leveraging the power of an in-memory data grid. While it may lack some of the advanced features of the Enterprise edition, it’s open-source nature and community support make it a compelling choice for many use cases.
