Re: Bug with caching SQLTypes in Connection:getSQLType(oid)

I was the one that started the stated thread. Sorry about not following
up, but I really do not know whether it was fixed or not.

I cannot remember why, but I know that I compiled a new driver, and it
did not get on very well with the backend (I think).

Anyway, the development was nearly finished, and when I moved to the
production server, not caching the requests was not critical, as the
client and the server are on two machines on the same subnet. The
development machine was in a different country than the server.

So, I "forgot" about the problem.

I think the interoperation issues were due to the fact we are on a 7.0.3
server, or something like that.

We may be changing our server from a 7.0.3 to a 7.1 or 7.2 by January so
I may test that again (new developments using similar techniques will
take place). BTW, which one do you recommend, 7.1 or 7.2? The server is
a RH6.2 2xPIII (800) 512Mb RAM, upgrading to 1Gb soon. The database size
is about 3Gb, and growing every day. Servlet operation against the
database is the main performance concern, and the server is most of the
time doing many INSERTs on different tables, and precalculating
statistics (SELECT - INSERT).

So, I recall: I was about to test more, but I could not. I may soon have
a second opportunity.

Sorry for not clarifying that before.
