Install Oracle ODBC on Solaris(Unix)_Connect Oracle_to_SQL_Server

I’ve searched a lot of software for to connect Oracle and SQL Server databases. There are a lot of software, but I couldn’t use any of them except DataDirect ODBC. Unfortunately, this soft is not free. I couldn’t find any free software that works on unix.

Let’s start installation.

1. Download DataDirect ODBC driver from here.

Choose your appropriate system(64-bit UNIX/Linux, 32-bit UNIX/Linux,…). After you choose it, there will appear Registration region. Fill it with your information and when you see the following section, do as it is shown on the picture:

DataDirect Registration Region

I chose Oracle, SQL Server and Solaris SPARC…Because I am trying to connect Oracle Database to SQL Server Database, note Oracle Database is installed on Solaris SPARC.

2.  Extract Downloaded file:



3. Go to the extracted file and run the following:

# ./unixmi.ksh

Is this the current operating system on your machine (Y/N) ? [Y] PRESS ENTER



EULA - Connect Products (revised 2/21/11)

Enter YES to accept the above agreement : YES


In the Key field, enter either EVAL or the Key provided.

Fill it with your registration information. I am writing EVAL because I just want to try it.

Name          :Mariam
Company       :JSC Bank of Georgia
Serial Number :EVAL
Key           :EVAL

Installation ended successfully.

3. Configure odbc.ini file, located in /opt/Progress/DataDirect/Connect_for_ODBC_61.

There will be written some information when you open this file, but the following entries are enough:

Description=SQL Server ODBC driver

Note I have changed the following values:

MS_SQLServer2000 – is your desired name, name it as you wish.(Will be used later)
Description – Just a descriptive text, write what you wish.
Database – Name of the SQL Server Database.
Address – Ip address of the server on which SQL Server Database is installed. 1433 is a default port for SQL Server.  Ensure that this port is opened on  firewall(Or you will not  be able to connect SQL Server)

4. Tnsnames.ora



DB_NAME_ALIAS – is your desired name.
DB_NAME – Is SQL Server Database name
1522 – Is any free port, If you have multiple listeners on the server(where Oracle is installed) choose any port that is available. – Ip of the server, where Oracle is installed

5. listener.ora

       (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = tcp)(HOST = = 1522))

     (PROGRAM= hsodbc)

Underlined entry is very important, or you will get  ORA-28500 error.

6.  Go to  the following directory: $ORACLE_HOME/hs/admin

There will be the file called inithsodbc.ora, copy that file and rename it like this: initDB_NAME_ALIAS.ora

# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.

# HS init parameters
set ODBCINI=/opt/Progress/DataDirect/Connect_for_ODBC_61/odbc.ini
# Environment variables required for the non-Oracle system

7.  Start the listener.

Before starting listener, ensure that ODBC lib directory is specified in the shared library environment variable:


After that we can start listener:

$ lsnrctl start LISTENER_DB_NAME_ALIAS

8. Create database link:

SQL> create database link LINK_NAME     
     connect to “username”     
     identified by “password”     
     using ‘DB_NAME_ALIAS’;


username– is the user in SQL Server Database.
password – is its password

Do not forget to use quotas(“”).

9. Check if it works

SQL> select * from dual@LINK_NAME;


That’s it Smile
