The SMS Storage DSA, EDSA, or GDSA view
shows a number of important CICS® Storage
Manager dynamic storage areas statistics values for the Dynamic Storage
Area (DSA), Extended Dynamic Storage Area (EDSA), or Grande Dynamic
Storage Area (GDSA) for the selected interval.
You can access the view from CICS Storage manager statistical
data in the sheet views, or the storage alerts in the Statistics
Alerts view. For details, see Visualizing storage.

The view has the following areas:
- Chart area
- The chart provides a graphical representation of the current size
of, and amount of storage used for, each DSA type in the selected
DSA over a number of intervals. For the Dynamic Storage Area (16-bit
storage), the CDSA, UDSA, SDSA, and RDSA are shown. For the EDSA (32-bit
storage), the ECDSA, EUDSA, ESDSA, ERDSA, and ETDSA are shown. For
the GDSA (64-bit storage), the GCDSA, GUDSA, and GSDSA are shown.
If enough intervals are available, the chart shows a maximum of 12
intervals: six before and five after the selected interval. Each interval
is shown as a separate column in the chart, and shows the time, interval
number, current active user transactions, peak active user transactions,
and number of times at MAXTASK. The column for the currently selected
interval is outlined. The bars and points on the chart provide an
indication of the value, not an actual value. To see the actual values
for an interval, hover over an area in the column to display a tooltip
that shows actual values.
- Data area
- The data area shows specific statistical information about the
DSAs during the selected interval. You can click the columns to change
the interval selection. The DSA types in the data area are color-coded
to match the colors of values on the chart. To change the colors,
click the Configure chart colors hyperlink,
and select Interval traces in the Chart Colors
pane in the Preferences window.
You can click
the APPLID hyperlink to display the SMS Storage global view
and view the Storage Manager global statistics for the selected interval.
For
each DSA type or current subpools value, you can click the hyperlink
to view the Domain Subpools view or the SMT
Task subpools view, as appropriate.
If you have an
active CICS SM connection to the region, you can click the Open
CICS Region Editor for region_name hyperlink
