Your
370
Virtual Machine Paging Activity
When you use the Local 3277 Session, you will be
making use of
"370
Virtual Machine" facilities. These
facilities require disk space equal in size to the size of
your
"virtual machine."
The size of your virtual machine can be as large
as
4
megabytes (4,194,304), but 1 megabyte (1,048,576
bytes)
or
even 512k bytes (524,288 bytes) is enough for
many users.
The
VM/PC
CMS Minidisks
Users of the Local 3277 Session generally prefer to have
collections of files available
on
their fixed disk(s). These
collections of files are called
"CMS
Minidisks," and their
sizes are determined by the amount of information the
user wants to have available.
A minidisk can be as large as
10 megabytes (an entire
fixed disk),
but
minidisks of about 1 megabyte provide
adequate space for many activities.
As you will learn in Chapter 3, you can allow several
users
to
share the space
on
the fixed disk(s). Each of
these users may wish
to
have their own minidisks.
It
is
helpful to know, however, that it
is
possible for several
users to use the same minidisk. Also, it
is
possible to
define a minidisk
on
a diskette, in which case the
maximum size of the minidisk is 354k.
Printer Spooling Activity
Users
of
the Local 3277 Session have the ability to tell
VM/PC
to print a file and, without waiting for the file to
print, continue with other activities. This capability
is
called "printer spooling"
and
is accomplished by copying
the files
to
be
printed onto a disk until there
is
time to
print them. As these files are printed, they are erased
from the disk.
You will want to leave some disk space free to allow for
spooling your printer files.
