Before Using VHS
Before using the VHS, determine the applications that should use VHS as a home
terminal.
To use VHS with an application:
1. Start VHS.
2. Stop the application.
3. Configure the application so that the VHS process is its home terminal. For more
information, see Specifying VHS as the Home Terminal of Applications.
4. Start the application.
Because the application is not available between the time you stop it and restart it, you
need to plan how to integrate VHS in your application environment to minimize
application downtime.
Starting VHS
To run VHS, locate and invoke the startup file created during the installation process.
For example, if the VHS startup file VHSSTART was created on $SYSTEM.STARTUP,
then you would type this command:
1> OBEY $SYSTEM.STARTUP.VHSSTART
When VHS starts, it reads and validates all ASSIGNs, parameters, and DEFINEs to
initialize its environment. If a parameter is not specified, VHS uses its default values
(listed in Section 2).
If the parameters are valid, VHS:
Caution. The hometerm of VHS should be a physical (static) device. A dynamic device, such
as a Telnet window, might cause problems when it is terminated.
