When dealing with temporary data sets in JCL, how can you ensure they are automatically deleted after job execution?
- Specify SPACE=(0,0) in the DD statement
- Use DISP=DELETE in the DD statement
- Use DISP=MOD in the DD statement
- Use DISP=NEW in the DD statement
DISP=DELETE is used to specify that a dataset should be deleted after the job completes, handling temporary data sets
What are the different methods for specifying input data for a program in JCL?
- Specifying input in the PROC
- Using the DD statement
- Using the DEFINE statement
- Using the INPUT statement
Input data for a program in JCL is typically specified using the DD statement
How can you specify the disposition of a dataset during allocation in JCL?
- Specifying the DSN parameter, indicating the dataset name.
- Specifying the LRECL parameter, indicating the record length of the dataset.
- Using the ALLOC parameter, indicating the allocation status of the dataset.
- Using the DISP parameter, indicating whether to keep or delete the dataset after job execution.
The DISP parameter determines what happens to the dataset after job execution.
In JCL, what are the differences between a system abend code and a user abend code?
- System abend codes are for informational purposes, while user abend codes halt job execution.
- System abend codes are hardware-related, while user abend codes are application-specific.
- System abend codes are user-triggered, while user abend codes are system-generated.
- System abend codes indicate successful job completion, while user abend codes signal errors.
System abend codes are related to hardware or software failures, while user abend codes are specific to the application and triggered by the user.
In JCL, what happens if the condition specified in an IF statement is not met?
- The job abends
- The job enters a loop
- The job executes the ELSE clause
- The job step is skipped
If the condition specified in an IF statement is not met, the job step is skipped
When using job dependencies, what does it mean if a job is set to execute "WHEN COND"?
- The job executes based on a time condition
- The job executes only when a predecessor job fails
- The job executes when a specific condition is met
- The job executes whenever it is scheduled
"WHEN COND" allows the job to execute when a specific condition is met
What happens when a job is triggered in a mainframe environment?
- The job is held in a queue
- The job is marked as complete
- The job is submitted for execution
- The job is terminated
When a job is triggered, it means it is submitted for execution in a mainframe environment
In JCL, what is conditional execution, and how is it achieved using job scheduling options?
- Specifying conditions based on the job class
- Specifying conditions based on the job priority
- Specifying conditions based on the success or failure of previous job steps
- Specifying conditions based on time
Conditional execution in JCL allows a step to be executed based on the success or failure of previous steps or specific conditions
In JCL, what happens when an EXIT statement is encountered during job execution?
- The job continues execution
- The job goes into a loop
- The job terminates abnormally
- The job waits for user input
When an EXIT statement is encountered, the job terminates abnormally
What happens if you don't specify a priority for a JCL job?
- The job gets the default priority assigned by the system
- The job goes into a waiting state
- The job is terminated immediately
- The job runs with the highest priority
If no priority is specified, the system assigns a default priority
