Starting the monitor

z/OS MVS Planning: Global Resource Serialization
SA23-1389-00

Enter the following command to start the monitor from the operator console:
START ISGECMON,INTERVAL=ssss

The INTERVAL parameter specifies, in decimal, the number of seconds that the monitor is to pause between each contention check. You can use the INTERVAL parameter to control how sensitive the program is. A larger value means that data set contention is not detected immediately. A smaller value causes contention to be detected more promptly, but a smaller value also causes the monitor to use more CPU cycles.
