Setup installs in the product installation directory a default system information file, named odbc.ini, that contains data sources. See "Data Source Configuration on UNIX/Linux" for an explanation of the odbc.ini file. The system administrator can choose to rename the file and/or move it to another location. In either case, the environment variable ODBCINI must be set to point to the fully qualified path name of the odbc.ini file.

For example, to point to the location of the file for an installation on /opt/odbc in the C shell, you would set this variable as follows:

In the Bourne or Korn shell, you would set it as:

As an alternative, you can choose to make the odbc.ini file a hidden file and not set the ODBCINI variable. In this case, you would need to rename the file to .odbc.ini (to make it a hidden file) and move it to the user’s $HOME directory.

The driver searches for the location of the odbc.ini file as follows:

If the driver does not locate the system information file, it returns an error.
