INFORMIXDIR environment variable

The INFORMIXDIR environment variable specifies the directory that contains the subdirectories in which your product files are installed. You must always set INFORMIXDIR. Verify that INFORMIXDIR is set to the full pathname of the directory in which you installed your database server. If you have multiple versions of a database server, set INFORMIXDIR to the appropriate directory name for the version that you want to access. For information about when to set INFORMIXDIR, see your Informix® Installation Guide.

pathname
is the directory path where the product files are installed.
To set INFORMIXDIR to usr/informix/, for example, as the installation directory, enter the following command:
setenv INFORMIXDIR /usr/informix
