connection between a PROCESS and a DISKFILE. If a Program has no lower
PROCESSes, then the connection is from the Program to the DISKFILE.
Selecting Objects Creating a selection of objects that the PC component can manage is one of Flow Map
Host’s objectives. A selection of approximately 100 objects is most useful. A selection
of approximately 400 objects is at the extreme end of usefulness. You can greatly
reduce the processing time of the Host and PC components by carefully selecting
commands and clauses.
All configuration statements are optional, but a configuration file must be supplied.
Most configuration statements are used to select the TPDC entities that will be used to
construct the Flow Map objects and connections. You can select entities by identifying
the entities by their names or by defining threshold values that are applied to the
counters in the entities.
Selection Statements Which objects are in the final output is determined by a combination of the following
commands and clauses:
SET ALLOW-TRANSIENTS command
GROUP commands
INCLUDE commands
EXCLUDE commands
SET DISCARD command
DISCARD clauses
THRESHOLD commands
APPLY-THRESHOLDS clauses
SET APPLY-THRESHOLDS command
The GROUP, INCLUDE and EXCLUDE commands select objects according to entity
identification values. The variations on DISCARD can include or exclude potentially
large numbers of DISKFILE or PROCESS objects. Transient objects can also be
included or excluded. THRESHOLD commands select objects according to attribute
values.
Selection phases are applied in the following priority:
1. Test for transients
2. Selection by GROUPs
3. Selection by INCLUDE
4. Exclusion by EXCLUDE
5. Test for DISCARD
6. Test for THRESHOLDS
