Author Database systems for OpenVMS/VAX?

I'm about to resurrect my old MicroVAX 3100-10 and I'm currently playing around with SIMH emulator and OpenVMS 7.3.
I'm generally interested in database systems and would like to know, which databases are available for VMS/OpenVMS for VAX?
I'm aware of
- RDB (so not available for VAX, unfortunately)

MySQL is good, but what other systems are there for hobbyist use (and where can I get them)?
I also heard of someone, who was able to build Ingres 8.9 (the free university Ingres) on VMS, but I couldn't find any detailed information about this. Does anyone know, if there is a VMS build available somewhere?
Are there some old DB systems for VMS (like Ingres, Adabas etc.) available for hobbyist users?

Thanks in advance.

Best regards,

There are several challenges with getting newer open source code to work on VAX/VMS.

It can expect the C long long type, which HP/DEC/CPQ C does not support.

I am not sure of the state of GCC/VAX. I know that some of the source was lost for the older port.

Also many of the projects expect that the GNU tool build tools are available.

Thanks, but I'm mostly looking for older, "ancient" systems. Like the old ingres 8.9 for VMS.

I am not aware of open source Ingres that will build on VAX. I used the closed source Ingress on VAX/VMS a long time ago. Ingres added support in their ii_termcap file for REGIS output on a VT340 for a project that I was working on back then. The sample ii_termcap entry has an easily fixed error that prevents it from just working.

Unfortunately even at 9600 baud, the REGIS character rendering was too slow to use, but it did allow a color display back then on real Digital terminals.

I know of some work reported on the sourceforge vms-ports project about attempts to port some databases to VMS. In those cases, the ports are dependent on HP fixing bugs in the new shared memory API, and that is not available on VAX.

You may want to see what it takes to get the berkely db from sleepycat to build on VAX/VMS.

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
