Stopping the collection of data

You can stop collecting dependency or affinity data on a particular region only when the Collector is running or paused on that region.

To stop collecting data on a specified CICS® region, use one of the methods shown in Table 1.

Table 1. Methods for stopping data collection by the Collector
Where used Command or function key
CINT transaction's Operations Menu, CIU100 Type 2 against a listed CICS APPLID and press Enter. You are asked to confirm that you want data collection to be stopped on the specified region.
CINT transaction's Operations Menu, CIU100 If there is more than one CICS region listed on the Operations Menu, you can type 2 against the first CICS APPLID in the list ALL and press Enter to stop the Collector on all the regions. You are asked to confirm that you want data collection to be stopped on all regions.
3270 terminal CINT STOP 1 
3270 terminal CINT STOPALL 2 
Console F cicsjob, CINT STOP 3 
Console F cicsjob, CINT STOPALL 4 
Application program EXEC CICS START TRANSID('CINT') FROM('STOP')  5 
Application program EXEC CICS START TRANSID('CINT') FROM('STOPALL')  6 

Notes:

 1  This option stops the Collector on the local CICS region; that is, the region to which the 3270 terminal is connected.

 2  This option stops the Collectors on all the monitored CICS regions.

 3  cicsjob is the name of your CICS startup job. This job stops the Collector on the local CICS region.

 4  cicsjob is the name of your CICS startup job. This job stops the Collectors on all the monitored CICS regions.

 5  This command, issued from a program initiated during the first quiesce stage of CICS shutdown (that is, a program specified in the first half of the PLT for CICS shutdown) stops the Collector on the local region. You are recommended to implement this command, to prevent the Collector delaying CICS shutdown if it is not in the STOPPED state. A PLTSD program to stop the Collector, CIUSTOP, is supplied with CICS IA. For information about installing and running PLTSD programs, see the CICS Customization Guide.

 6  This command, issued from a PLTSD program on the local CICS region, stops the Collectors on all the monitored CICS regions.

Using one of the methods in Table 1 stops the Collector recording any dependency or affinity data in the CICS region until you next start the Collector. Stopping the collector also destroys the data space, and saves the data collected to the VSAM data files.

If there are many data records to be saved, the Operations Menu screen might be frozen for some time, until the records have been saved.

You might want to stop the Collector, on a specified CICS region, when it has detected all dependencies there. You can find out when this has happened from the Collector Statistics Menu screen, CIU150; see Displaying Collector statistics for a specified region. When the Collector has detected all dependencies, the “Date/time of last change” field changes very infrequently and, if optional periodic saves are performed, the “Records written last save” field is consistently near zero.
