Known bugs in OBDC?

From
"Robert John Shepherd"
Date:
Has anyone experienced problems with ODBC driver on NT4?

My database server died today, and when it came back up all IIS could
get out of the ODBC driver was:

  Microsoft OLE DB Provider for ODBC Drivers error '80004005'
  Could not send Query to backend; Could not send Query to backend;
Socket has been closed

pgAdmin II connects fine with no complaints from the same box, it just
seems to be the ODBC connections that are failing big time.

Hi,

What are you trying to do through IIS? pgAdmin uses the ODBC for all
it's connections, so I'd guess for the most part the driver installation
is fine.

Connection pooling could be the cause.

My website uses IIS to connect to Postgresql, having migrated to this
from MS-SQL 7 (which I had never seen this problem with).

Whilst I'm happy to accept there may be issues between IIS and the pgsql
ODBC driver that have caused this, I'm convinced this has nothing to do
with my postgresql installation having whacked up the debug levels and
logging to the max on the install and watched the logfiles during this
problem.

I thought that the ODBC driver currently didn't support connection
pooling?

Or is this a case of IIS performing the pooling?

I agree, it's probably not you installation. Did you see Hiroshi's
message about pooling? Can you tell IIS not to do it?

Regards, Dave.

Are there any implications for the server in telling IIS not to pool
connections? Is it going to suddenly spawn more postgresql processes
than the box can handle? :)

I wouldn't have thought so, but that is somewhat outside my area of
(ahem) expertise. I try to avoid IIS whereever possible.

Maybe yes.
I've just put an improved version of dll on my home page
  http://w2422.nsk.ne.jp/~inoue/ .
Please try the dll.
