Pathway Installation Considerations
These routines are examples of how to start and stop the VHS Browser and might
not be appropriate for all installations. It is recommended that you customize these
routine macros for your specific system needs.
Pathway Installation Considerations
The following subsections describe additional considerations for installing VHS
Browser into your Pathway environment.
VHS Browser Stand-Alone Pathway Configuration Files
When you install the VHS Browser as a stand-alone Pathway system, several files are
created. Table 2-6 on page 2-25 lists all the files created. Three Pathway configuration
files are important to note:
The VHS Browser facility is added and started automatically whenever you start your
Pathway system cold.
Security Considerations
The VHS Browser facility does not provide its own security checking. VHS relies on the
security system provided by Pathway to check for two authorization levels:
•
Who can install and start the VHS Browser facility
•
Who can run the VHS Browser facility
When INSTVHS is run, the VHS ISV files are restored with the operator’s ownership
and security values. Verify these values to ensure that they are acceptable. VHS
installation procedures require read access to the ISV files and result in files being
copied and created on the VHS-BROWSER-SUBVOL parameter subvolume.
Modifying the VHS Configuration Files
After installing the VHS process, VHSCI, VHS GUI Agent facility, and the VHS Browser
facility, you can modify the VHS configuration files, see Figure 2-5 on page 2-29.
