> ### Setting Environment Variables

> You must set several environment variables for the ODBC Client on Linux and UNIX by executing a shell script located in the installation directory.

> To execute the shell script:

> - If you are using the Bourne or Korn shell, type:
> - `. sqlnk.sh` (for 32-bit client)
> - `. sqlnk64.sh` (for 64-bit client)
> - If you are using the C shell, type:
> - `source sqlnk.csh` (for 32-bit client)
> - `source sqlnk64.csh` (for 64-bit client)

> Executing this shell script sets the following environment variables:

> ODBCINI | Specifies where the centralized odbc.ini or odbc64.ini file is located.
> SQLNK_ODBC_HOME | Specifies the full path of the directory containing the ODBC Client shared libraries.

> Executing this shell script also sets the appropriate library search environment variable (LD_LIBRARY_PATH on Solaris and Linux, SHLIB_PATH on HP-UX, or LIBPATH on AIX).
