Subject: RE: Win2k Pro. is mess...
choosing the right database product
It
could be that Interbase is a very recent addition to the open source /
freeware bunch. Also, prior to version 6, Interbase was
missing some essential data types, which made it a
bit less approchable. My company is still evaluating Interbase, but so
far
we
haven't found any "issues" and are extremely pleased with the JDBC driver and
the performance/features of this product.
There appears to be an issue setting different
character sets for the JDBC driver in data-sources.xml, but that is probably
true
for
all JDBC drivers and setting their extended parameters (it could be a problem
with Orion) and it's not a show stopper for us.
At
some point in time, we were also evaluating mySQL, but (AT THE TIME) it had no
transaction support, JDBC drivers were
in
flux and no blobs.
Personally, I believe that InterBase 6 offers more
features then mySQL. Another FREE option appears to come from
SAP
driver and a bunch of tools. It would be nice to hear
from somebody who know more about it.

You are probably right in your asumptions. Might I
ask why you have chosen to go for PostgreSQL? To me it seems a bit too
uncertain to have two pieces of experimental software in one project.
Personally I was thinking of switching to either MySQL or Interbase once my
system goes on-line. I have used Interbase quite a lot, just not with EJBs,
and it is totally free and open source nowadays. I have no experience with
MySQL, but as far as I have read on this list, quite many people are fond of
it, and it seems that the use of MySQL is a question of once needs for
transactions (which MySQL does not support).
I
am wondering if anyone is using the prepackaged Hypersonic database in
production... It has not given me any trouble during this development
project... yet... - I would feel MUCH better about using a 10+ years old
well-tested database like Interbase, and I simply do not know why more
people are not using it.
Any comments anyone?

DB
Hello Randahl,
First of all, I appreciate your
idea.
Yes, we came to the near conclusion that it
was not orion but it was postgresql.
To tell the truth, I believe in
orion but not very much so in postgresql.
As a matter of fact, we are using a CVS
version of PostgreSQL because
the released version of postgresql does not
yet support the right join sql statement.
To make matters worse, the Linux JDBC driver
was not working properly on the timestamp
field before I made a modification on the
driver. We were totally forgetting all about this.
Our Windows developers have had no
problems with ODBC drivers so far, out of which
we can guess it is not the DB itself but it
is the Linux JDBC driver.
What are your thoughts?
Once again, thank you very much.
Simon

I know this is a wild guess, but just to make
sure, I would of course do a disk scan on that machine to make sure it
is not a hardware problem - these things do happen, I am
afraid.
Another good thing would be to run the
application on a _different_ Win2K Pro. machine to make sure it is not
just something which is specific to only her single
machine.
BTW, I would doubt PostgreSQL more on Win2K
than I would doubt Orion. Orion is a java application, which gives it a
pretty good chance of running in the same way on different platforms. To
the best of my knowledge PostgreSQL on Win2K is a port of the code from
another platform, and from reading articles at PostgreSQL's web-site it
seems it is not totally stable on Win2K. I have seen at least two posts
on this list where people recommends *not* using PostgreSQL from Win NT
based systems - not yet, anyway.
I have used Orion on Win2K with no problems -
but then again I do *not* use PostgreSQL....
Hope you find a solution
Yours

Hello,
I do not really know if this is because
she's using Window 2000 Professional.
All our employees use Windows 2000
Servers or Linuxes or Solarises except for one person.
The exception is Windows 2000
Professional. The problem occurs only at her computer.
Once she updates a DB record, it messes
up another record. This does not
happen all the time, but once in a blue
moon. This is why I can't catch the problem in my code.
And I do not think it is my
code. I am using CMPs and orion 1.3.8 with
PostgreSQL.
I doubted postgresql and orion in the
beginning, and now I narrowed it down to orion because
it may be machine specific as I mentioned
earlier. Why does a DB server have to do with
a specific machine? Then what? An App.
Server which holds a session to a machine?
I am lost. Does anyone have any clue? I
really really hope it's my code.
I appreciate your attention.
Simon
