Configuring ODBC Driver for SQL Server: A Step-by-Step Guide

The ODBC (Open Database Connectivity) driver is a crucial component in connecting to various databases, including SQL Server. In this article, we will explore the process of configuring the ODBC driver for SQL Server using DataDirect 7.1 Wire Protocol.

Pre-requisites

Before you begin, ensure that the DataDirect 7.1 driver has been installed and configured on your Linux-based system. You should also have a basic understanding of ODBC and its configuration files.

Step 1: Create an ODBC.ini File

Create a copy of the system odbc.ini file in the home directory of your database instance, for example, db2inst1. The path to this file is typically /opt/branded_odbc/IBM_Tools/odbc.ini.

Step 2: Configure the ODBC Driver

Open the odbc.ini file and add the following configuration details:

* `description=DataDirect 7.1 SQL Server Wire Protocol`

* `IpAddress=IP address of DB2 database server`

* `Driver=/opt/branded_odbc/lib/VMtrc00.so`

This configuration specifies the DataDirect 7.1 SQL Server Wire Protocol driver and sets the IP address of your DB2 database server.

Step 3: Set Environment Variables

To ensure that the ODBC driver is loaded correctly, you need to set environment variables. You can do this by adding the following lines to your shell profile or startup script:

* `export DJX_ODBC_LIBRARY_PATH=/opt/branded_odbc/lib`

* `export SHLIB_PATH=$SHLIB_PATH:/opt/branded_odbc/lib`

* `export LIBPATH=$LIBPATH:/opt/branded_odbc/lib`

Step 4: Load the ODBC Driver

Once you have set the environment variables, load the ODBC driver by running the following command:

`export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/branded_odbc/lib`

This command loads the DataDirect 7.1 SQL Server Wire Protocol driver and sets the library path.

Step 5: Test the Connection

To test the connection to your DB2 database server using the ODBC driver, use a tool like isql or db2cmd. These tools allow you to connect to your database instance and execute queries.

In conclusion, configuring the ODBC driver for SQL Server using DataDirect 7.1 Wire Protocol involves creating an odbc.ini file, setting environment variables, loading the ODBC driver, and testing the connection. By following these steps, you can successfully establish a connection to your DB2 database server using the ODBC driver.
