3.8 Installing with the POLYCENTER Software Installation Utility
3.8.4.1 Requesting an Explanation to Questions
To request a full description of all product options and information, use the /HELP
qualifier with PRODUCT INSTALL. To request help about an individual question,
press the Help key or PF2 in response to the question. The POLYCENTER
Software Installation utility displays a description (if one is available) and a
summary of disk and memory requirements for the option.
The following example uses the Help key:
$ PRODUCT INSTALL UCX
.
.
.
Optional example files may be installed... [YES]
Help
The example files include client server programming examples.
Block Size - Total: 507 Optional: 0 Required: 507
Global Pages - Total: 0 Optional: 0 Required: 0
Global Sections - Total: 0 Optional: 0 Required: 0

The amount of information varies; some products provide more information than
others, and some products provide no information.
3.8.4.2 Accepting Default Answers
Default answers come from one of three places:
• A product configuration file (PCF), if one is supplied
• The product database (PDB), for upgrades of previously installed products
• The product description file (PDF)
If you specify an input PCF and it contains an answer for an option, the default
answer from the PCF is used. Depending on the entry in the PCF, the default
answer may or may not be allowed to change.
If no input PCF exists, or if the input PCF does not contain an answer for an
option, the default answer comes from either the PDB or the PDF. If the PDB is
present and contains the option, then the default answer comes from the PDB. If
the PDB is not present (a new installation) or does not contain the option (a new
option), then the default comes from the PDF. Default answers that come from
either the PDB or PDF may be changed.
To answer an option, either press Return to accept the default answer, or supply
your own answer and then press Return.
Some products contain a subset of questions or options. During an installation
procedure, you can accept the default values for an entire subset or you can
answer each option in the subset.
When you select an option that has suboptions, the POLYCENTER Software
Installation utility will ask:
Do you want the defaults for all options? [YES]
If you answer YES, you will not be asked about the subitems. Instead, the utility
will use the defaults for the subitems. If you answer NO, the utility asks you
about each subitem.
