CLDATA Description

The Cluster Data Report (see CLDATA) contains information about all clusters selected for reporting. The report is organized as follows:

1. The report is subdivided into groups and where possible a group will be shown on one print line. A user can optionally select to suppress any or all detail groups.
2. Most groups are further subdivided into items that are shown in a keyword fashion; that is, the item name followed by an equal sign (=) and then the value (for example, RECSZ=100).
3. VSAM definitions incorporate many default values. In order to produce a concise report, CA Disk can suppress a group item if the default value is in effect. For example, the default attribute for a cluster is NOSPAN, so if NOSPAN is in effect, NOSPAN will not be displayed in the attribute group. However, if SPAN is in effect, SPAN will be displayed, as it is a non-default value.
4. If all items in a group are suppressed, the printing of the entire group will also be suppressed. For example, if all attributes in effect are the default values, the attribute line will be suppressed.
5. Where non-keyword values are to be printed, CA Disk lists the values in alphabetical order. This simplifies locating a particular group item.
6. An attempt has been made to shorten the conventional report line length in order to improve the usability of CA Disk in a terminal environment.
