Installing multiple copies of the IBM Data Server Driver for ODBC and CLI on the same machine

To install multiple copies of the IBM Data Server Driver for ODBC and CLI on the same machine, you need:

• to obtain the compressed file that contains the driver.
  • See: Obtaining the IBM Data Server Driver for ODBC and CLI.

For each copy of the IBM Data Server Driver for ODBC and CLI that you are installing:

1. create a unique target installation directory; and
2. follow the installation steps outlined in Installing the IBM Data Server Driver for ODBC and CLI.
3. Ensure the application is using the correct copy of the driver. Avoid relying on the LD_LIBRARY_PATH environment variable as this can lead to inadvertent loading of the incorrect driver. Dynamically load the driver explicitly from the target installation directory.

If you are installing two copies of the IBM Data Server Driver for ODBC and CLI under the following conditions:

• the operating systems on the target machine is AIX®; and

• the DB2® Version 9 CD is mounted on the target machine.

the steps you would follow are:

1. Create the two directories, $HOME/db2_cli_odbc_driver1 and $HOME/db2_cli_odbc_driver2, where you will install the driver.
2. Locate the compressed file that contains the driver on the install CD. In this scenario, the file would be called db2_driver_for_odbc_cli.tar.Z.
3. Copy db2_driver_for_odbc_cli.tar.Z to the install directories, $HOME/db2_cli_odbc_driver1 and $HOME/db2_cli_odbc_driver2.
4. Uncompress db2_driver_for_odbc_cli.tar.Z in each directory:

   cd $HOME/db2_cli_odbc_driver1
   uncompress db2_driver_for_odbc_cli.tar.Z
   tar -xvf db2_driver_for_odbc_cli.tar
   cd $HOME/db2_cli_odbc_driver2
   uncompress db2_driver_for_odbc_cli.tar.Z
   tar -xvf db2_driver_for_odbc_cli.tar

5. Delete db2_driver_for_odbc_cli.tar.Z.
