Additional Configurations:

In order to use the Essentia's ODBC Driver you must configure your Windows system, and be able to execute the ping and telnet command to the unix host succesfuly. This commands must make their conection via Window Sockets. This lines must be added to the /etc/services file (unix host) and the services file of the Window system (The services file on Windows can be anywhere, depending your Windows Sockets implementation, ask your System Administrator):

	
		Environ________7100/tcp_______# Iql Server
		Environ-deb_____7110/tcp_______# Iql Server

On the unix host you need to update the /etc/inetd.conf file, the lines you need to add are the following:

	     Environ__stream__tcp__nowait__root__ /usr2/idea43/rbin/iqlsrv__iqlsrv !e/etc/iqlsrv.env -f  /tmp/iqlsrv.log

IMPORTANT: Use tabs instead of spaces on the underlines chars (___), if you use spaces instead of tabs your configuration will not work properly!.

Replace '/usr2/idea43' with the directory where you have installed the iqlsrv file.

There is another file that must be configured, this file will set the necessary environment for the server Iql (/etc/iqlsrv.env). This file must set the following variables: Por ejemplo:

		IDEAFIX=/usr2/idea43
		DATADIR=$IDEAFIX/data
		ESSENTIA=$IDEAFIX/essentia
		LANGUAGE=spanish
		SERVERS="aurus;denarius"

		
		# ps -ax | grep inetd
		   85  ?  S <   0:00 inetd
		15095 pp0 D <   0:00 grep inetd
		# kill -1 85
