Description
TIMESTOP specifies the point at which Model 204 automatically terminates the run.
The run ends when the number of CPU milliseconds left for the run equals the setting of TIMESTOP. To initiate a command or SOUL request, the milliseconds remaining must be twice the value of TIMESTOP.
Files can be logically inconsistent after automatic termination. Use of the ROLL BACK and ROLL FORWARD facilities ensures the logical consistency of files.
If TIMESTOP is set to 0, the Model 204 timing facility's automatic shutdown is bypassed. If, in addition, the JCL EXEC statement parameter TIME is set to 1440 (24 hours), the z/OS automatic shutdown is bypassed, and Model 204 continues to run indefinitely until brought down by other means.
