1 TransactionsEssentials Licensing Questions

1.1 Why is it free?

It is free because we want to reach the largest possible community of fans that are happily using our product - secretly hoping that you will recommend us to your friends. Once in a while, somebody comes along who likes us enough to pay for our commercial offerings so in the end everybody wins. It's that simple…

1.2 Is the (open source) license viral?

No it is not. We use the Apache license, second version. You can use TransactionsEssentials in just about any way you like, without the need to open up the sources of your own work.

1.3 Can I bundle TransactionsEssentials in my closed source product?

Yes, the apache license clearly allows this. The more people use TransactionsEssentials, the better we like it.

1.4 What does the patent notice mean? Why does it say that I shouldn't implement the interface com.atomikos.icatch.Participant?

It is possible to implement the Participant interface in ways that may violate known patents and patents pending to which the TransactionsEssentials license does not (and cannot) grant the rights. This is particularly true in the case of web services. Although it is unlikely that anybody will want to do this, the warning is still there in the notice file. The built-in implementations of Participant (e.g., in the com.atomikos.datasource.xa package) do not violate any patents - at least not to our knowledge - so there is no need to worry.

1.5 Are contributions distributed as open source too?

All approved contributions are guaranteed to be distributed under the same open source (apache) license as TransactionsEssentials. Contributions by the Atomikos Community, for the Atomikos Community.

1.6 Why do contributors need to sign an agreement?

Approved contributions are guaranteed to be distributed under the same open source (apache) license as TransactionsEssentials. We ask contributors to sign an agreement for the following reasons:

  • So that Atomikos can publish the contributions as apache-licensed.
  • So that Atomikos can protect contributors from infringement law suits and other legal risks typical for open source projects.
  • So that Atomikos can represent the entire community in such legal affairs (without having to gather all contributors in court).
  • To keep patented code out of TransactionsEssentials, so that TransactionsEssentials can remain free and open.

In other words: the agreement allows Atomikos to protect and enforce the rights of the entire community. This is similar to what many open source organizations do, including Apache (to name just one).

2 ExtremeTransactions Licensing Questions

2.1 Is ExtremeTransactions free?

No. Customers who pay us often find it hard to justify a budget for something that is free, so ExtremeTransactions includes extra benefits that are reserved for paying customers. And to be totally honest: we can't afford to offer everything we do for free; somebody needs to pay our lunch smile

2.2 Is ExtremeTransactions open source?

No, it is not. Although based on our open source core, this product is closed-source and has a proprietary license. You may use this product only if you are a subscriber (see Buy Online). Educational licenses are available for approved institutions - mail us to find out more.

2.3 Can I evaluate ExtremeTransactions before buying?

No. We offer paid support and commercial value-added features that need to be configured with our help. Since we already develop and offer TransactionsEssentials for free, we cannot afford to also give free evaluation support for ExtremeTransactions, so free evaluations do not make sense. Suppose you were serious about using ExtremeTransactions and were evaluating it - what would happen if you encountered a problem? Your management would probably deny the budget for a purchase because evaluation did not work. Wouldn't you rather have us fix the problem with our support? That's exactly what you get when you pay…

2.4 Can I redistribute ExtremeTransactions?

Yes, if you have an agreement to do so. Redistribution agreements are available from Atomikos.

2.5 How does the pricing model of ExtremeTransactions fit virtualization?

Our prices are not based on core counts or CPU counts. We don't care how many times you install it (because we think the more you use it, the more value it brings you).

3 Support Questions

3.1 Is prior application certification required before we can get support?

No. This used to be the case but we've moved away from that because people did not like it. These days, we'll give you support as soon as you subscribe so there are no delays involved.

4 Other Questions

4.1 Why is Atomikos not in standards bodies like OASIS?

Although we did web service transactions before the term "web service" was invented, we are not in standards bodies like OASIS because we own important intellectual property rights that we would need to give up due to such membership (yes, we believe in IPR).

However, we are closely observing any standardization process related to transactions and history has proven that we are successful at supporting any standard that comes up. We are also glad to give feedback on such standardization efforts provided that it does not affect our IPR.
