To remove Materials Studio servers from a Linux system
1.Log in using an account with administrative privileges.
2.Ensure that all server jobs running under this installation are stopped. You can use the Server Console from a Materials Visualizer installation under Microsoft Windows to check whether any jobs are still running. Details of, and controls to stop, any jobs that are running on a particular server gateway can be found under each of the server nodes of the server gateway that you intend to remove. Available server gateways are listed under the Console Root > Server Management > Server Gateways node of the Server Console.
3.
Stop the gateway daemon.

Change directory to the Gateway folder and run:
./msgateway_control_<portnumber> stop

4.
If your system is running Red Hat Linux and you have configured your gateway to start automatically, then:
◾Use chkconfig to remove all the links to /etc/rc.d/init.d/msgateway_control_<portnumber> using the command:
/sbin/chkconfig --del msgateway_control_<portnumber>
◾Remove the /etc/rc.d/init.d/msgateway_control_<portnumber> file using the command:
rm /etc/rc.d/init.d/msgateway_control_<portnumber>

5.
If your system is running SuSE Linux and you have configured your gateway to start automatically, then:
◾Use chkconfig to remove all the links to /etc/init.d/msgateway_control_<portnumber> using the command:
/sbin/chkconfig --del msgateway_control_<portnumber>
◾Remove the /etc/init.d/msgateway_control_<portnumber> file using the command:
rm /etc/init.d/msgateway_control_<portnumber>

6.
Remove all gateway configurations by running the gwdeconfigureall tool:
◾cd into etc/Gateway at the top level of your Materials Studio installation and run:
./gwdeconfigureall

7.Delete the top-level directory and all the subdirectories into which you installed Materials Studio using the rm -rf command.
