Everyone,
which databases are available on QNX? Preferably I want to use free stuff if
possible. How about MySQL, is it possible to run MySQL on QNX?
Thanks
John
I just tried compiling mysql and had some success. The errors that came up
seem to be configuration type problems (some includes that should/shouldn’t
be there, etc.) so it’s probably not a bad port. Looks like about 98% of
the files compile without error (based on a ‘make -k’ and a rough guess).
cheers,
Kris

MySQL has two ports, one at:

I have been using Empress on RTP for almost a year now.
I believe they provide a version of Empress for free download from their
website
that allows you to evaluate and develop. Once you go to production though,
you
will need to purchase a license. Their prices aren’t bad though, about 1/4
to 1/3 the
price of a SQLServer or an Oracle. There’s an ODBC driver that works from
Windows, a precompiler for embedded SQL statements in your C/C++ code,
two additional, lower level data access methods (that I have not tried), an
HTML
parser allowing you to embed SQL in your HTML code and a report writer.

I have a data base design for QNX 4 that I’d love to port to Nto, especially
since it can easily take advantage of multi-threading. The biggest
challange is removing some (a small amount) of propriatery code from it. I
already know how I would redo the sections in question and the new design is
much better than the old.
It’s an ISAM design, though. Not SQL. It is absolutely lightning fast
however. It has many configurable caching options. Can be linked into a
program or called as a server. It also has the option of being passed a
list of filters and returning multiple qualifying records from a single get.
Has both C and C++ APIs. Does anyone want to fund my redevelopment of it?
You won’t be sorry.

If ISAM is what you’re after, then check out Faircom’s C-TREE product.
Apparently they have a QNX port. A few years ago, I used their product
on SCO UNIX and was quite happy with its performance.

Hello DZM
(That’s a funny name.)
Anyway, ISAM = Indexed/Sequential Access Method. The rules are typically
these:
- records are (usually) fixed in length
- the data base has 1 or more index, where an index is a list of fields by
which the file is sorted. - access to a record is by a key which refers to an index. I.E. Give me
the employee record who’s SSN is 123-45-6789 - once you have accessed a record you may then read sequentially forward or
backward through the file.
SQL is a more interpreted language that returns tables, not just records.
I.E. Give me all of the employee records who’s SSN is greater than or equal
to 123-00-0000 and less then or equal to 123-99-9999 and who’s state is
‘CA’.
SQL is very popular scripting kind of language and arguably more versitile.
All SQLs (I think) will be slower than pretty much all ISAMs. All ISAMs
will require writing a program to perform whatever function you want to
acomplish. Many SQL’s (I think) actually sit on top of an ISAM.
QDB, the Q-TPS Data Base is an ISAM data base. In addition to the features
listed above it supports multiple keys (i.e. SSN, last name/first name,
city/state/zip, etc.), getting blocks of records with filters (much like a
SQL) and Getting Cached Keys before you decide to get whole records, which
can greatly speed up accesses. It also supports a varity of caching
algorithms. QDB is also, and primarily, very fast.
I have a beta version of QDB available. It is being tested right now and
had exposed a real shortcoming in the Neutrino memmove() function. I have
re-written the memmove() function in asm and will be posting that function
tomorrow. In the mean time I will be creating a new version of QDB probibly
next week and testing it.
Let me know if you are interested in a free beta version.

Both Empress and Postgres work very well, although they have different
philosophies. Empress targets more at embedded, so they lack certain
features (autoincrement is most missing one for people coming from
Windows/Oracle world) but claims much better raw performance (I have not
seen sufficiently detailed benchmarks to support that claim however).
Postgres is very sophisticated and extensible, performance depends heavily
on schema and fine tuning. It does not ‘just compile’ on QNX and porting is
non-trivial enough to turn away anyone without experience. Get binary from
qnxzone.

Every time I go look at www.qnxzone.com (including just minutes ago),
there’s some news items on the newsZone page, but every other page
except for registration (including softwareZone and developerZone) is
utterly blank, with the same notation that’s been there for months:
“Coming soon…”
Am I looking the wrong place? Am I in the twilightZone

It may be very active underneath, but you can’t tell from the surface.
I’ve been periodically checking back for the last 3 months and nothing
has changed except an occasional new bit. It seems very–leisurely .
I’m not complaining (per se), I’m just trying to figure out what
everyone is talking about when they say “check qnxzone”.

We have no primary PHP coder since a while back,
that’s why it’s a bit stalled, also the other admins have been very busy
at their own ends.
Hopefully we will get something new up without boring everyone to death

There’s a MySQL port at http://developers.cogentrts.com/repository. Use the
package manager to get it. The only problem is that it requires a little
playing
with the host name when you try to connect - it only supports a TCP/IP
connection
and when it sees that you are connecting from the local host it tries (and
fails) to
create a UNIX-domain socket. It’s on my list of things to fix.
Cheers,
Andrew

There are rumors that UNIX domains are implemented in QNX 6.2
