v EXEC CICS SET STATISTICS ON|OFF RECORDNOW.
CICS writes requested statistics to SMF even if, on one of the following, you
have specified OFF:
v The STATRCD system initialization parameter
v The CEMT SET STATISTICS command
v The RECORDING option of the EXEC CICS SET STATISTICS command.
Statistics counters are not reset.
Requested reset statistics
differ from requested statistics in that all statistics are collected, and all statistics
counters are reset. They are invoked by either of the commands:
v CEMT PERFORM STATISTICS RECORD ALL(RESETNOW)
v EXEC CICS PERFORM STATISTICS RECORD ALL(RESETNOW).
You can also invoke requested reset statistics when setting statistics recording
status ON or OFF, using either of the commands:
v CEMT SET STATISTICS ON|OFF RECORDNOW RESETNOW
v EXEC CICS SET STATISTICS ON|OFF RECORDNOW RESETNOW.
Note that it is valid to specify the RECORDNOW RESETNOW options only
when there is a genuine change of recording status. For example, coding EXEC
CICS SET STATISTICS ON RECORDNOW RESETNOW when STATISTICS is
already set ON causes an error response.
CICS writes requested reset statistics to SMF even if, on one of the following,
you have specified OFF:
v The STATRCD system initialization parameter
v The CEMT SET STATISTICS command
v The RECORDING option of the EXEC CICS SET STATISTICS command.
Unsolicited statistics
are automatically gathered by CICS for dynamically allocated and deallocated
resources. CICS writes these statistics to SMF just before the resource is
deleted if:
v Statistics recording status was set ON by the STATRCD system initialization
parameter (and has not subsequently been set OFF by a CEMT SET
STATISTICS or EXEC CICS SET STATISTICS RECORDING command).
or
v ON is specified on CEMT SET STATISTICS.
or
v The RECORDING option of the EXEC CICS SET STATISTICS command is
set to ON.
CICS collects unsolicited statistics for:
Autoinstall
Whenever an autoinstalled terminal entry in the TCT is deleted, CICS
collects statistics covering the autoinstalled period since the last
interval. This period includes any delay interval specified on the system
initialization parameters AILDELAY or AIRDELAY.
