Setting Up VHS Environments
Setting Up VHS Environments
The grouping of multiple VHS processes that share one VHS prompt file and one VHS
primary log file is called a VHS environment. You might have one VHS environment for
ATM applications and another VHS environment for point-of-sale programs. You can
have up to a hundred separate VHS environments. Each VHS environment has a
name that you specify, such as ATM, POS, or DEV.
Figure 1-5 shows a VHS configuration that includes an operator console program
(such as ViewPoint or NonStop NET/MASTER). This configuration has two
environments: ATM and POS. You use Pathway screens to move from environment to
environment.
For the clarity of the diagram, only one VHS process is depicted per environment. You
could assume that each $ATM and $POS represents one or more VHS processes.
