For a cross-reference of Enform reports to the data files they require, see the file
XREFRPTS in the base or work subvolume. For a sample of this file, see Appendix B,
Cross-Reference of Enform Queries to Data Files.
Entities
The TPDC component configures Measure to collect all the applicable entities on the
node being measured. For a list of these Measure entities, see Table 3-2 on page 3-7.
The TBUILD macro of SPAM can help determine automatically what charts and reports
can be produced from any given Measure data files.
SPAM also creates the Performance Aggregate entities listed in Table 3-4. For an
alphabetical list of all entities with their attributes and attribute definitions, see
Appendix A, Entity and Attribute Definitions.
Caution. The selection criteria of your queries might result in nothing selected for certain
reports.
If you execute Enform reports that find no qualifying records (for example, by inadvertently
excluding everything), most of the Enform reports will fail with the Enform error “!!!ERROR
[138] Invalid time specified” because no records qualified. This situation also occurs if you
execute Enform reports against empty data files. TPRODUCE attempts to provide helpful hints
on the possible cause of such errors.
