What parameter of the job statement is used to limit the CPU time consumed by the job?
-
EXECMAX
-
LIMIT
-
TIME
-
RUNTIME
In JCL (Job Control Language) on IBM mainframe systems, the TIME parameter on the JOB statement specifies the maximum CPU time that a job step can use. If a job step exceeds this time limit, the system abends the job with a specific error code (often S322). EXECMAX and RUNTIME are not valid JCL parameters, and LIMIT is used for different purposes like limiting output records, not CPU time.
To answer this question, we need to understand the parameters used in a job statement, specifically those related to limiting CPU time.
Option A) EXECMAX - This option is incorrect because EXECMAX is not a valid parameter used to limit CPU time. It is used to specify the maximum number of times a job can be executed.
Option B) LIMIT - This option is incorrect because LIMIT is also not a valid parameter used to limit CPU time. It is used to specify the maximum amount of resources a job can consume, such as memory or disk space.
Option C) TIME - This option is correct because the TIME parameter is used to limit the CPU time consumed by the job. It specifies the maximum amount of CPU time that the job can use before it is terminated.
Option D) RUNTIME - This option is incorrect because RUNTIME is not a valid parameter used to limit CPU time. It is used to specify the maximum amount of time a job can run, including both CPU time and waiting time.
The correct answer is Option C) TIME. This option is correct because the TIME parameter is specifically used to limit the CPU time consumed by the job.
