DataNucleus Support

Free Support

With any software, there are times when you need assistance to make full use of it. Here at DataNucleus we want you to make the best of the software that we provide, and we provide a level of free support. DataNucleus provides access to public discussion/IRC facilities, providing a place for you to discuss issues you are having. We don’t guarantee to provide answers, simply providing places where you could get some level of support when people have time.

  1. Check the Documentation for DataNucleus AccessPlatform before anything else. The answer is usually there, either in a tutorial/example, or in one of the many guides. Yes I know you can’t be bothered, but then this is where you can do things for yourself.

  2. Look in the DataNucleus LOG. This usually contains a lot of information that may answer the issue. You can always configure the log to give more output.

  3. Try a recent release to see if your version is out of date, or download the latest code to see if the expected result is then achieved.

  4. Go to the DataNucleus Groups.IO OR DataNucleus Gitter and ask. Always try to give as clear a description of the problem as possible, together with your input data, and any associated log output. These are the only sites where we provide any free support.

  5. If you have a problem and don’t report it, or report it on a third party site that we don’t use then it really doesn’t say much for your participation in the open source community.

Please do not use Twitter and expect answers to support questions
We have very little time for this type of support and contributors to DataNucleus are more likely to get any available free support


We are committed to safeguarding the privacy of users of our support services and we will only use the information we collect about you lawfully and in accordance with the Data Protection Act 1998 (the “Act”).

Data Protection legislation and the Act is currently going through a period of change. The introduction of the European Union’s General Data Protection Regulation (GDPR) and the new British Data Protection Bill, which will replace the Act and is currently passing through Parliament is the basis of this change. This Privacy Notice is therefore intended to comply with the Act and GDPR but may change over time.

Sharing with third parties

We will, in general, not share your information with third parties under any circumstances. The only exceptions to this would be :

  • To external experts where a particular problem that you request support on requires expertise outside of our organisation; in this case we will explicitly request authorisation from you to contact them, and what data, if any, should be shared. Such recipients would only have access to your personal information as required by them to perform their functions, and would not be permitted to use such personal information for any other purposes. Any such recipients will be subject to contractual confidentiality obligations.

  • To government or law enforcement authorities if we determine in our sole discretion that we are under a legal obligation to do so.

Although we will do our best to protect your personal information, you should be aware that the transmission of information via the internet is not completely secure and we cannot guarantee the security of your personal information transmitted to the Website or any third party; for this reason, any transmission is at your own risk.

Retention of Personal Data

How long we need data depends on what we are using it for, whether that is to provide services to you, for our own legitimate interests (described above) or so that we can comply with the law. We will actively review the information we hold and when there is no longer a customer, legal or business need for us to hold it, we will delete it securely. This review will include whether a support contract is still active.
