The Common Area Storage Usage Report tracks the allocation of
virtual storage at a monthly, weekly, daily, hourly, or
detail level. Figure 2-167 shows an example of a monthly
Common Area Storage Usage Report and Figure 2-168 shows the
hourly form of the report. In the hourly form, data for one
day is displayed by hour using the DAYS time-span of the MVS
Virtual Storage System Usage File (SCPVSM).
REPORT OPTIONS
The Common Area Storage Usage Report supports standard time
selection options, as well as SYSID selection and external
data selection. These options are controlled by the control
options discussed in Section 2.5.6.
DATA ELEMENTS
The elements reported are divided into the following
categories:
o CSA Average Values
o SQA Average Values
o CSA Average by Key
All categories contain above and below 16MB usage values.
CSA AVERAGE VALUES
CSA Average Values is shown in terms of the total allocated
storage and the average amount of unused storage.
ALLOCATED The amount of storage (pages) allocated actively
CSA: in the CSA, from the VSMAUCSL and VSMAUCSH
elements.
FREE PAGES The total amount of storage available in the
(BYTES): CSA, from the VSMAFCSL and VSMAFCSH elements.
LARGEST The total amount of storage available in the CSA
FREE BLOCK: in a contiguous block, from the VSMABCSL and
VSMABCSH elements.
ALLOCATED The total amount of storage (pages) allocated in
AREA SIZE: the CSA, from the VSMATCSL and VSMATCSH
elements. This measurement represents a "high
water" mark of storage allocated within the CSA.
The difference between this measurement and the
ALLOCATED CSA represents storage fragmentation.
SQA AVERAGE VALUES
SQA Average Values are shown in terms of the total allocated
storage and the average amount of unused storage.
ALLOCATED The amount of storage (pages) allocated actively
SQA: in the SQA, from the VSMAUSQL and VSMAUSQH
elements.
FREE PAGES The total amount of storage available in the
(BYTES): SQA, from the VSMAFSQL and VSMAFSQH elements.
LARGEST The total amount of storage available in the SQA
FREE BLOCK: in a contiguous block, from the VSMABSQL and
VSMABSQH elements.
ALLOCATED The total amount of storage (pages) allocated in
AREA SIZE: the SQA, from the VSMATSQL and VSMATSQH
elements. This measurement represents a "high
water" mark of storage allocated within the SQA.
The difference between this measurement and the
ALLOCATED CSA represents storage fragmentation
for SQA storage residing below 16MB. For SQA
residing above 16MB, it normally has an
allocated area equal to the specified ESQA size.
CSA AVERAGE BY KEY
CSA Average by Key values are shown in terms of the total
allocated storage and represent MVS Storage Keys 0 through 7
and 8 through F.
KEY x The amount of storage (pages) allocated in MVS
ALLOCATION: Storage Key x in the CSA, from the VSMAxCSL and
VSMAxCSH elements, where x represents one of the
MVS storage protection keys.
A reporting option permits either reporting by storage key or
reporting by storage subpool and key. Additionally, it is
possible optionally to produce all of the above-reported
elements with MINIMUM/MAXIMUM values to provide for more
detailed analysis.
