INFORMIXSQLHOSTS environment variableThe INFORMIXSQLHOSTS environment variable specifies where the SQL client or the database server can find connectivity information.

INFORMIXSQLHOSTS environment variable

The INFORMIXSQLHOSTS environment variable specifies where the SQL client or the database server can find connectivity information.

pathname: The full path name of the connectivity information file.
UNIX: Default =$INFORMIXDIR/etc/sqlhosts
Windows server: Default = %INFORMIXDIR%\etc\sqlhosts.%INFORMIXSERVER%

For example, the following command overrides the default location and specifies that the mysqlhosts file is in the /work/envt directory:

setenv INFORMIXSQLHOSTS /work/envt/mysqlhosts
