Hello list, 


I'm having a problem with a oracle HS, unixodbc & freetds...I'm posting
this here first because the trace shows unixodbc is unhappy.

Oracle HS is writing this in the HS log file: 


[Generic Connectivity Using ODBC] version:

connect string is: defTdpName=ascom;SYNTAX=(ORACLE8_HOA,





<datasource name='ascom' type='GENERIC_ODBC_FOR_HS' connect='ASCOM'>


<misc year2000Policy='-1' consumerApi='1'

parserDepth='2000' noInsertParameterization='true'


ORACLE GENERIC GATEWAY Log File Started at 01-Jun-06 23:57:47

[unixODBC][Driver Manager]Data source name not found, and no default

specified (SQL State: 00000; SQL Code: 0)

(Last message occurred 2 times)


The part from unixODBC seems to be stopping the show here I think...but
I'm not sure.

Strange thing is that I can connect&query with isql on this db and that
seems to work excellent.

The fact that isql working makes me believe unixodbc & freetds are ok
from the commandline.


Some info: 


Unixodbc version: 2.1.1


Compile-time settings (established with the "configure" script):

Version: freetds v0.63

MS db-lib source compatibility: no

Sybase binary compatibility: unknown

Thread safety: yes

iconv library: yes

TDS version: 8.0

iODBC: no

unixodbc: yes 


Odbcinst.ini has an entry for freetds

Oracle user has a $HOME/.odbc.ini 

The system has /etc/odbc.ini 

Both of these odbc.ini files are symbolic links to

(I presume this should function ?)


The oracle user has an env var ODBCSYSINI=/usr/local/etc/odbc.ini and an


Still, when called through HS unixODBC seems unable to find the dsn
files, most likely due to my stupidity :-)

I've tried setting the envs in listener.ora, it seems to go the unixodbc
according the listener trace, but unixodbc in turn is unhappy...


What am I missing here ?

Thanks for any help :-)
