I'm using FreeTDS with Perl and mod_perl in an Apache 2.2.15, mod_perl 2.0.4,
Perl 5.12.2 environment (brand spankin new) and I'm experiencing some
discrepencies between running my DBD::Sybase (ver 1.10)/DBI (ver 1.615) on
the command line and from within mod_perl.

We are connecting to 3 different SQL servers: 12.5 Sybase on Linux, 12.5
Sybase on Solaris 5.8, and MS SQL.

Everything's fine from the command line, but from mod_perl, we're seeing the
following FreeTDS trace:

log.c:190:Starting log file for FreeTDS 0.82

And this is what I'm seeing on the solaris box in the error log:

My freetds.conf config for this server looks like this:

[GSAPROD]
host = sybx.myco.com
port = 5100
tds version = 4.2

And in our web server logs, we see this:

DBIWrapper
connect('packetSize=4096;loginTimeout=5;server=GSAPROD;scriptName=httpd;hostname=client-host;database_name=ourdb','user',...)
failed: OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (78) NUMBER
= (49)
Server GSAPROD, database
Message String: Unexpected EOF from the server
OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (78) NUMBER = (34)
Server GSAPROD, database
Message String: Adaptive Server connection failed

I've looked at the LD_LIBRARY_PATH, SYBASE, FREETDS and other environment
items, but have been unable to find the problem.

It was suggested in this thread
(https://lists.ibiblio.org/sympa/arc/freetds/2006q2/019981.html) that
explicitly setting the database_name
Any help will be appreciate?

Eric
