This
chapter describes the concepts related to installing, upgrading,
and updating OpenVMS layered products.
Instructions
for installing, upgrading, and updating the OpenVMS operating system
software are in the current OpenVMS Upgrade and Installation Manual
for VAX, Alpha, or I64 systems.
Two methods are available
for installing or upgrading layered-product software:
The VMSINSTAL.COM command
procedure
The POLYCENTER Software Installation utility
Each layered product is packaged to use one of these. Refer
to the layered product's documentation for information about which
to use.
