The ICVR system initialization parameter
specifies the default runaway task time interval in milliseconds as a decimal number.
- ICVR={2000|number}
- You can specify zero, or a number in the range 250 through 2 700 000, in multiples of
250. CICS® rounds down values that are not multiples of 250.
This is the RUNAWAY interval used by transactions defined with RUNAWAY=SYSTEM. See TRANSACTION attributes for further information.
- CICS might purge a task if it has not given up control
after the RUNAWAY interval for the transaction (or ICVR if the transaction definition specified
RUNAWAY=SYSTEM). If you code ICVR=0, runaway task control is inoperative for transactions specifying
RUNAWAY=SYSTEM in their transaction definition (that is, tasks do not get purged if they appear to
be looping). The ICVR value is independent of the ICV value, and can be less than the ICV value. CICS runaway task detection is based upon task time, that is, the
interval is decremented only when the task has control of the processor.
