Is there any freely available distribution of any Relational DBMS for RSX-11 ? Or for any other PDP-11 OS ?

None that I am aware of. This also ties in to the question of what is
means by a relational database. You could possibly argue that
Datatrieve-11 is. But it's technically not free anyway, but at least
it's possible to find distributions. Oracle is certainly a relational
DB, but that one is definitely not free, and not easy to find either.
Same story for Mimer.
(All for RSX by the way. Not sure if anything except Datatrieve exists
for other OSes...)

Uh, relational database on a 16 bit processor with minimal memory & disk storage (by current standards)?Seems very unlikely, but never say never, I guess...

RDBMS were 'defined' by Codd in 1970, the first commercial RDBMS was released in 1979 (Oracle), and the PDP-11 was discontinued in the mid to late 1990s, so I guess there *could* have been an RDBMS running on a PDP-11, but seems unlikely to me...

Ingress was born on the 11/70 although I’m not sure how easy it would to find that and compared to later version it’s pretty unadorned.   Berkeley DB also started on the 11 although it more designed for casual databases than some like Ingress.  

Sent from a handheld expect more typos than usual

Are you really looking for a "relational database"?  There's this website:  oracle-v2.nl, but you'll probably spend a lot of time getting it working (I haven't tried it or looked for a download).  If on the other hand, if all you want is keyed/index access to files (i.e. Cobol's "ORGANIZATION INDEXED"), RMS is available on the PiDP-11 image you are probably running.  (run $rmsdes).

Docs are at bitsavers, rsx_11Mplus_V4.x/8a

Getting Oracle working does not take any effort, but finding the actual
distribution is another story.

Same with Mimer.

Datatrieve-11 is easier to find, and I'd say it's a relational database
as well. However, the query language for Datatrieve-11 isn't SQL.
Actually, Mimer don't use SQL on the PDP-11 version either.

But manuals are around, so if someone wants to play, it's not hard to
get running at all.

And yes, RMS is another option. It's pretty much like NOSQL databases.
For some, that might indeed be enough as well.

I'll have a look at RMS, I'm not familiar with it.

It will probably be enough for my needs, but anything-SQL would be my first choice.

RMS is pretty low level. For sure look it over, but it might appear a
little daunting if you aren't used to low level file access handling
like that.

Datatrieve-11, while not using SQL, have a fairly straight forward query
languange, and an interface so that you can write applications that
access data trough it fairly easily. But it does also depend on what
languange you are planning to use...

You will probably need to read through some manuals no matter what.

The oracle-v2.nl is my website, and it runs Oracle v2.1 in simh.
It can be accessed using a telnet connection, all the info is on the site.

And yes, I do have the distribution kit, both for V2 and V4.1 (fits on a RL02 image).

Will the V2 distribution kit become available? Maybe but not for now.

That would be cool if possible.  I started out with Oracle RDBMS V4 on VAX/VMS V4 in 1984. I'm still an Oracle DBA - currently we're using Oracle 19c

I wish I had some older copies.  I have some V7 on CD for OpenVMS and Alpha but that's as early as I have.

That would be quite nice !
I too started with Oracle V4 around 1990 on a PC as an applications programmer. I think it was the first version available for a PC ?

On a side note, I read somewhere that the "first" Oracle (v2) was developed and originally released on PDP-11. Is there any truth to this ?

Oracle V2 was written in MACRO-11 and did run on any pdp-11 with RSX-11M or RSX-11M+ and required I&D space.
Up to V5.1 was ported to RSX-11M+, V5.0 and v%.1 required quite some fiddling as the Oracle kernel became quite big (for that time).

V2 did run on VMS in the compatibility mode.

After the V2 release, the whole SW was rewritten in C, and became V3.

V3.1.3 was the first on VMS as well on a few Unix systems. V#.1 was ported by me to the Danish Supermax machine,
a sort of multi cpu system based on the MC 68000

V3 did not have transaction control (ACID), it was very similar to MySQL V3.

From V4 and onwards, the ACID stuff became part of it.

Dear All,

 We can't have a RDPMS discussion in the PiDP11 group without at least mention of MUMPS(DSM).
 I would hope that there are some images around somewhere. But, not sure if it was ever released off license.

The largest PDP-11 installation I ever saw was at a medical services company in Louisville Kentucky that had I want to say it was four very built out 11/70s running MUMPS. Amcor was the name of the place. Their building with the custom built data center room is still there too. This is in Louisville, Kentucky.

DSM-11 can be found online. If it is "legal" or not is another question.
But that is also true of all other DEC OSes for the PDP-11.

I think there's a license available for hobbyists for the DEC OSs, but maybe not including VMS.

As for DSM I think the license is still held by InterSystems.

Sortof half but no. There was a license to use some specific older
versions of the OSes on a specific simulator done by DEC.
In truth, you have a much easier time to run VMS legally as a hobbyist
than any DEC OS for the PDP-11 (sadly).

Very possibly.
