About This Quiz

VSAM is a high-performance access method used to organize data in the form of files in Mainframes that was introduced in the 1970s. Job Control Language, as discussed in class, is the command language of which is the commonly used Operating System in the IBM Mainframe computers. Take this ultimate quiz on JCL and VSAM in preparation for the mock test to see how ready you are.

    JES3 is environment is centralized

    • True

    • False

    Correct Answer
    A. True
    Explanation
    JES3, which stands for Job Entry Subsystem 3, is indeed a centralized environment. It is a mainframe operating system component that manages the execution of batch jobs in a centralized manner. JES3 receives job requests from multiple users and systems, and then schedules, controls, and monitors the execution of these jobs. This centralized approach allows for efficient resource allocation and management, ensuring that jobs are processed in a controlled and organized manner. Therefore, the correct answer is true.

     MSG LEVEL = (1,1) means print

    • All JCL statement will be printed including allocation message

    • Print only JCL Statements

    • © Print only JOB statement

    • None of the above

    Correct Answer
    A. All JCL statement will be printed including allocation message
    Explanation
    The correct answer is "All JCL statement will be printed including allocation message." This means that when MSG LEVEL = (1,1), all JCL statements, including the allocation message, will be printed. This setting allows for a more detailed printing of the JCL statements, providing information about the allocation of resources during job execution.

    Maximum number of steps in a JOB are     

    • 255

    • 256

    • 16

    • 15

    Correct Answer
    A. 255
    Explanation
    The maximum number of steps in a job is 255. This means that a job can have a maximum of 255 different tasks or operations.

    TSO is a program executed by MVS to get your program and JCL       into machine code

    • True

    • False

    Correct Answer
    A. True
    Explanation
    TSO (Time Sharing Option) is a program executed by MVS (Multiple Virtual Storage) operating system to interact with the mainframe system. It provides a command-line interface that allows users to enter commands and perform various tasks such as running programs, editing files, and submitting JCL (Job Control Language) for execution. TSO does not directly convert programs and JCL into machine code, but it provides the necessary environment and facilities to execute programs and process JCL, which eventually results in the generation of machine code. Therefore, the given statement is true.

    Which is not a keyword parameter    

    • CLASS

    • PGM

    • MSGLEVEL

    • PRTY

    Correct Answer
    A. PGM
    Explanation
    In the given list, "PGM" is not a keyword parameter. The other options, "CLASS", "MSGLEVEL", and "PRTY" are all keyword parameters.

    All available storage is assigned to a job or jobstep, if region is coded as            

    • 0K

    • 0M

    • 0K or 0M

    • 1K

    Correct Answer
    A. 0K or 0M
    Explanation
    The correct answer is "0K or 0M". This means that if the region is coded as 0K or 0M, it indicates that no storage is assigned to the job or jobstep. This could be used when a job or jobstep does not require any storage allocation.

    The  Utility used to delete dataset, find databset, cataloged & uncataloged dataset        

    • IEBGENER

    • IEBCOPY

    • IEFBR14

    • IEHLIST

    Correct Answer
    A. IEFBR14
    Explanation
    IEFBR14 is a utility program used in mainframe systems to create or delete datasets. It can also be used to find datasets and determine if they are cataloged or uncataloged. The utility is commonly used for simple file management tasks and does not perform any actual data processing.

    • 16

    • 15

    • 12

    • 32

    Correct Answer
    A. 15
    Explanation
    In a single job, a maximum of 15 instream procedures can be coded.

    Maximum number of DD statements in a job      

    • 3276

    • 3273

    • 3723

    • 3237

    Correct Answer
    A. 3273
    Explanation
    The maximum number of DD (Data Definition) statements in a job is 3273. DD statements are used in JCL (Job Control Language) to define the input and output data sets for a job. Each DD statement specifies a unique data set and its characteristics. The maximum limit of 3273 DD statements ensures that a job can define a large number of data sets for processing.

    Rate this question:

  • 11. 

    Which statement is correct-

    • Job-Region will override Exec-Region

    • JOB-CONDITION will overwrite EXEC-COND

    • EXEC-TIME will override JOB-TIME

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the above statements are correct. In the given options, each statement indicates that a specific attribute or condition will take precedence over another in a job or execution scenario. The first statement suggests that the job region will have priority over the execution region. The second statement states that the job condition will overwrite the execution condition. Lastly, the third statement asserts that the execution time will override the job time. Therefore, all three statements are accurate in describing the hierarchical order of attributes in the given scenario.

    SCRATCH specifies entry of dataset should not physically deleted        from the volume                                      

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is "SCRATCH specifies entry of dataset should not physically deleted from the volume". The correct answer is False. This means that the statement is incorrect. SCRATCH actually specifies that the entry of a dataset can be physically deleted from the volume.

    IEFBR14 use to check the syntax of JCL  without affecting any dataset

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true. IEFBR14 is a utility program used in mainframe systems to create a dummy dataset. It is often used to check the syntax of Job Control Language (JCL) without affecting any actual datasets. The program does not perform any actual processing or data manipulation, but it allows users to verify the correctness of the JCL syntax before executing the job.

    JOB Accounting information and TYPERUN is a positional parameter

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because TYPERUN is not a positional parameter in the context of JOB Accounting information. A positional parameter refers to a parameter that is specified by its position in the command line or script, whereas TYPERUN is likely to be a specific value or option that is not determined by its position. Therefore, TYPERUN is not a positional parameter in this case.
