Link to SQL Server fails

Question

Oracle: 11gR2 on Linux and tryed following the instructions found on (therefore some generic stuff inside the files):
http://www.gotodba.com/install-and-configure-db-link-to-sql-server-database-in-linux.html
Steps:
Step 1
Installed FreeTDS and configured /etc/unixODBC/odbc.ini with the following:
[ODBC Data Sources]
MYDB2=IBM DB2 ODBC DRIVER
SQLDB=FreeTDS
[SQLDB]
Driver = /usr/local/freetds/lib/libtdsodbc.so
#Driver = /usr/lib64/libodbc.so
Server = 10.0.0.9
Database = komspom_kanc
Port = 3488
TDS_Version = 8.0
Afterwards I can successfully login to the SQL server using:
isql -v SQLDB <userid> <password>
Step 2
Created the initSQLDB.ora file in $ORACLE_HOME/hs/admin with the lines:
# This is a sample agent init file that contains the HS parameters that are
# needed for the Database Gateway for ODBC
# HS init parameters
HS_FDS_CONNECT_INFO = SQLDB
HS_FDS_TRACE_LEVEL = 0
HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so
HS_DB_NAME = SQLDB
HS_DB_DOMAIN = GOTODBA.COM
HS_FDS_SUPPORT_STATISTICS = FALSE
# ODBC specific environment variables
set ODBCINI=/etc/unixODBC/odbc.ini
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
Step 3
Added the following lines to listener.ora:
SID_LIST_LISTENER_TWNYCSLD04=
(SID_LIST=
(SID_DESC =
(ORACLE_HOME = /shared/app/komisija/product/11.2.0/dbhome_1)
(SID_NAME = SQLDB)
(PROGRAM = dg4odbc)
(ENVS=LD_LIBRARY_PATH=/usr/lib64:/usr/local/freetds/lib:/shared/app/komisija/product/11.2.0/dbhome_1/lib)
and reloaded the listener:
lisnrctl reload
Step 4
Added the following line to tnsnames.ora:
SQLDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = linux1.kons.gov.ba)(
(CONNECT_DATA =
(SERVICE_NAME = SQLDB)
(HS = OK)
afterwards tnsping SQLDB runs fine...
Step 5
Created a link as sys:
create database link sqldb.gotodba.com
connect to user
identified by "password"
using 'SQLDB';
But after I run
select * from "myTable"@sqldb.gotodba.com;
I get:
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from SQLDB.GOTODBA.COM
What could be wrong and how to test where exactly shit hits the fan, pardon my language :)

Answer 1

Ok, my bad... Was editing the listener.ora blindly instead of reading the documentation. I think ths should now be more or less correct?
# listener.ora Network Configuration File: /shared/app/komisija/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = linux1.kons.gov.ba )(PORT = 1521))
ADR_BASE_LISTENER = /shared/app/komisija
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC =
(ORACLE_HOME = /shared/app/komisija/product/11.2.0/dbhome_1)
(SID_NAME = SQLDB)
(PROGRAM = dg4odbc)
(ENVS=LD_LIBRARY_PATH=/usr/lib64:/usr/local/freetds/lib:/shared/app/komisija/product/11.2.0/dbhome_1/lib)
lsnrctl status now returns:

The command completed successfully
However the select now returns:

select * from "tblAktiCX"@sqldb
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
And that's it..no error message... where to go from here?
