The resource file for configuring Gateway communication is $XAPPLRESDIR/DbuimxOrb.
$SYBASE/interfaces (where the environment variable SYBASE is defined as the directory in which Sybase is installed). It is not necessary to have Sybase installed on every machine where a Gateway daemon may execute. All that is required is that the $SYBASE/interfaces file be accessible from each machine on which a Gateway daemon may execute. See the User's Guide.ORACLE-SID environment variable to specify it. If multiple Oracle databases are necessary, you must make use of the OracleDatabase resource in the $XAPPLRESDIR/DbuimxOrb resource file. See the User's Guide for more information.$INFORMIXDIR/etc/sqlhosts (where the environment variable INFORMIXDIR is defined as the directory in which Informix is installed). It is not necessary to have Informix installed on every machine where the Gateway daemon may execute. It is required that the $INFORMIXDIR/etc/sqlhosts file be accessible from each machine on which a Gateway daemon may execute. Also, the /etc/services file on each machine must be set up properly for each Informix on-line service port.
