Note: If there are a large number of data records to be saved, the CAFF screen
may be frozen for some appreciable time, until the records have been saved.
You may want to stop the Detector when it has detected all affinities. This is
indicated by the “Date/time of last change” field changing very infrequently and, if
the optional periodic saves are performed, the “Records written last save” field
being consistently near zero.
If CICS shuts down normally, but the Detector is not stopped, the Detector
eventually detects that CICS is not running and terminates cleanly with a save.
Changing the Detector options
You can control how the Detector operates by changing the options that it uses.
Option values are preserved in the Transaction Affinities Utility control file,
CAUCNTL, so that they can be used across separate runs of the Detector. For
more information about the control file, see “The control record VSAM file” on
page 17.
Notes:
1. Generally, any option can be changed while the Detector is stopped. However,
some options can also be changed while the Detector is paused or running.
(These options are identified in the descriptions on page 37.)
2. You can change an option even if the Detector is stopped and the Reporter is
running (that is, reading the CAUCNTL file).
To review and change the options that the Detector uses, press the F4 function key
of the Detector control screen, CAFF01. In response, the Detector displays its
options screen, CAFF02 (shown in Figure 7) is displayed.
To update the options screen, press Enter.
To return to the Detector control screen, press the F12 function key.
