Oracle Coherence = Is this a library free of charge and can be used in my programm?

sorry for asking such a question:

But I was not able to figure out if the Coherence http://www.oracle.com/technetwork/middleware/coherence/downloads/coherence-101246.html can be used in my programs.

Does anybody know what the licencing costs and if there is an "open/free" version that I can use in my programs free of charge? I know there are commerci开发者_如何学运维al editions available, but is there also a free edition available? (if not I think I will have to use infinispan?)

Thanks Jens

Oracle Coherence is covered by the OTN License. You can see the terms of the license at OTN License Agreement. The license states the following:

You may not:

• use the programs for your own internal data processing or for any commercial or production purposes, or use the programs for any purpose except the development of your application;
• use the application you develop with the programs for any internal data processing or commercial or production purposes without securing an appropriate license from us;
• continue to develop your application after you have used it for any internal data processing, commercial or production purpose without securing an appropriate license from us, or an Oracle reseller;
• remove or modify any program markings or any notice of our proprietary rights;
• make the programs available in any manner to any third party;
• use the programs to provide third party training;
• assign this agreement or give or transfer the programs or an interest in them to another individual or entity; - cause or permit reverse engineering (unless required by law for interoperability), disassembly or decompilation of the programs;
• disclose results of any program benchmark tests without our prior consent.*

No, Oracle Coherence cannot be used free of charge. It is a commercial product only. If you work for a large company, the company may already license it as part of a larger Oracle license agreement, for example as part of a WebLogic Suite license or something like that. If you work for a start-up, you may be able to get it for low cost or no charge for a period of time through an Oracle start-up program. If you work for a small or medium sized business, it will be very hard to get it, as the license is per-core (per "Oracle CPU") and the price is fairly high.

As 2020, there is now a free and open source version of Oracle Coherence, labeled as Community Edition.
