SMS Storage DSA, EDSA, or GDSA view

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.

You can also access this view by clicking the DSA, EDSA, or GDSA hyperlink in the SMS Storage global view, or the CDSA, UDSA, ECDSA, EUDSA, GCDSA, or GUDSA hyperlink in the SMT Task subpools view.

The information line shows the time interval of the records.

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 to edit CICS resources directly. For more information, see Using resource editors in the CICS Explorer User Guide.
