To begin the VMFSGMAP session, enter the VMFSGMAP command with
the name of the saved segment product parameter file (SEGBLD), the
name of the z/VM saved
segments component in the saved segment product parameter file
(ESASEGS), and the name of the system saved segment build list (SEGBLIST),
which is also the name of the associated SEGDATA file:
vmfsgmap segbld esasegs segblist
Note: If you enter only VMFSGMAP, this command will use the
default PPF and build list names as shown here.
Entering the VMFSGMAP command places you into an XEDIT session.
The initial display is the Segment Map panel. VMFSGMAP divides your
system storage into 4 MB ranges: 0-3 MB, 4-7 MB, and so on. If a saved
segment or saved system is wholly or partially defined in one of these
4 MB ranges, VMFSGMAP displays a heading for the storage range on
the panel, followed by a segment map record for each saved segment
or saved system defined in the range. A segment map record identifies
the status, name, and type of the saved segment or saved system and
pictorially shows the amount of storage used.
If a saved segment is defined in the SEGDATA file and on the system,
the segment map record contains the version from the SEGDATA file
and indicates by a status code (column 1) how the definitions compare.
Figure 1 shows an example of the Segment
Map panel. This example shows that the first 4 MB range of storage
that contains a saved segment or saved system is X'004-007' MB.
Following the heading for the X'004-007' MB range is a map
record for the CMSPIPES saved segment. The map record supplies the
following information about CMSPIPES:
Its status is 'P', for planned, which means it is defined in the
SEGDATA file but not on the system.
Its type is DCSS, and it occupies the 1 MB storage range from
7-8 MB.
Only the first four 64 KB segments of the DCSS contain
data, and the permitted access is read-only.
For information about the syntax of segment map records, see the
description of the VMFSGMAP EXEC in the
z/VM: VMSES/E Introduction and Reference. Figure 1. Example of the VMFSGMAP EXEC
Segment Map Panel. PF keys 13-24 provide the same functions
as PF keys 1-12.
