LDG Storage DSA or EDSA view
The LDG Storage DSA or LDG Storage EDSA view shows a number of important CICS® Storage Manager dynamic storage areas statistics values for the Dynamic Storage Area (DSA) or Extended Dynamic Storage Area (EDSA) for the selected interval. You can use it to analyze the program activity, program storage usage, and program compression activity in relation to the CICS Dynamic Storage Areas (DSAs).

- Chart area
- The chart provides a graphical representation of the current amount of storage used, amount of storage allocated, and percentage use, 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. 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 current setting of 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 LDG Loader global view and view the Loader and Storage Manager global statistics for the selected interval.
For each DSA type, program storage, 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.
