Technical Support


Free Support

Since Hercules is an Open Source product owned by no one in particular and copyrighted by many (lots of very sharp people have contributed over the years to Hercules’s success), there doesn’t exist any type of official “Technical Support Department” within any type of company or anything (like there usually is for closed-source products).

Instead, as with most Open Source products, there simply exists a dedicated group of individuals and enthusiasts who are willing to put in their spare time helping others with whatever problems and/or questions others may have regarding it. This dedicated group of Hercules enthusiasts is known as “our user community”, and it honestly does, in this author’s opinion, a pretty darn good job at providing whatever technical support most people find themselves needing.

If your question and/or concern regarding Hercules is not already addressed in our FAQ and/or documentation then you might consider posting your question to either the main Hercules-390 group or one of the more “focused” support groups listed further below:

The Hercules-390 group is your primary source for free Hercules support, and you are strongly encouraged to subscribe. It is a vibrant, active community with hundreds of members, most of whom are very knowledgeable in many different areas of mainframe technology, both from a hardware point of view as well as from an operating system and software point of view.

In addition to the main Hercules-390 group, other more specialized Hercules groups also exist to provide more focused support for a variety of popular IBM mainframe operating systems, such as DOS/VS, z/VSE, VM/370, z/VM, MVS, z/OS, etc:
