TIME parameter

Parameter type

Keyword, optional

Purpose

Use the TIME parameter to specify the maximum amount of time that a job may use the processor or to find out through messages how much processor time a job used.

The system terminates a job that exceeds the specified time limit unless an installation exit routine at exit IEFUTL extends the time. Exit routine IEFUTL is established through System Management Facilities (SMF).

You can use the TIME parameter on a JOB statement to decrease the amount of processor time available to a job or job step below the default value. You cannot use the TIME parameter on a JOB statement to increase the amount of time available to a job step over the default value. To increase the allowable time over the default value, use the TIME parameter on the EXEC statement.

For releases prior to MVS/ESA SP Version 4 Release 3.0, the amount of time that a job step receives might be slightly more or less than the requested processor time. The exact amount of processor time is based on certain system events.

As of MVS/ESA SP Version 4 Release 3.0, the job step receives at least the requested amount of CPU time. Based on system events, additional CPU time might be provided.
