An IMS Batch program can be run as

technology programming languages

  1. a DLI

  2. a BMP

  3. a DBB

  4. All of the above

Show answer
Correct Option: D

AI Explanation

To answer this question, we need to understand the different types of programs in IMS (Information Management System).

A. DLI (Data Language Interface) - This is a type of IMS program that interacts with IMS databases using the DL/I (Data Language Interface) calls. It allows the program to read, write, update, and delete data in IMS databases. Therefore, an IMS Batch program can be run as a DLI.

B. BMP (Batch Message Processing) - This is another type of IMS program that processes messages in a batch environment. It can receive messages from IMS online programs or other batch programs, perform processing on the messages, and send responses back. Therefore, an IMS Batch program can be run as a BMP.

C. DBB (Database Batch) - This is a type of IMS program that performs batch database processing. It can read, update, and delete data in IMS databases without using the DL/I calls. Therefore, an IMS Batch program can be run as a DBB.

D. All of the above - This option is correct because an IMS Batch program can be run as a DLI, BMP, or DBB. All three options are valid ways to run an IMS Batch program.

Therefore, the correct answer is D) All of the above.

ADRDSSU Utility is used
technology programming languages

  1. To reduce free space fragmentation

  2. To copy or move Datasets from one DASD to another

  3. All of the above

  4. None of the above

Show answer
Correct Option: C
Explanation:

To answer this question, the user needs to know what ADRDSSU Utility is used for.

The ADRDSSU Utility is a tool used for backup, restore, and copying datasets. It can be used to copy or move datasets from one DASD to another, and can also be used to reduce free space fragmentation.

Therefore, the correct answer is:

C. All of the above

Which of the following is not an ADRDSSU control statement
technology programming languages

  1. DUMP

  2. COPY

  3. MOVE

  4. CONVERTV

Show answer
Correct Option: C
Explanation:

To solve this question, the user needs to be familiar with ADRDSSU (ADRDSSU) utility and its control statements.

Now, let's go through each option:

A. DUMP - This is a valid ADRDSSU control statement. It creates a dump of a dataset to an output dataset.

B. COPY - This is a valid ADRDSSU control statement. It copies a dataset or a group of datasets to another dataset or a group of datasets.

C. MOVE - This is not a valid ADRDSSU control statement. Although MOVE is a valid COBOL verb, it is not a control statement used in ADRDSSU.

D. CONVERTV - This is a valid ADRDSSU control statement. It converts a VSAM dataset to a non-VSAM dataset or vice versa.

Therefore, the answer is:

The Answer is: C

Parameters which can be overridden in a VSAM file

What are the files that can be created using LIKE Parameter?
technology programming languages

  1. VSAM File

  2. Tape File

  3. none of above

  4. Both a and b

Show answer
Correct Option: A
Explanation:

To answer this question, the user needs to know about the LIKE parameter in mainframe programming.

The LIKE parameter is used to create a new file that has the same record-layout as an existing file. This is useful when you want to create a new file with the same structure as an existing file, but with different data.

Now, let's go through each option and explain why it is right or wrong:

A. VSAM File: This option is correct. You can use the LIKE parameter to create a new VSAM file that has the same record-layout as an existing VSAM file.

B. Tape File: This option is incorrect. You cannot use the LIKE parameter to create a new tape file. Tape files are typically used for backup and archival purposes, and do not have a record-layout like VSAM files.

C. None of above: This option is incorrect. As explained above, option A is correct.

D. Both a and b: This option is incorrect. Although option A is correct, option B is not.

Therefore, The Answer is: A. VSAM File

The exact syntax for the REFDD Parameter
technology programming languages

  1. REFDD=*.ddname

  2. REFDD=*.stepname.ddname

  3. REFDD=*.jobstepname.procstepname

  4. REFDD=*.jobstepname.ddname

Show answer
Correct Option: A

The interface used to connect the program to the Database in IMS is
technology programming languages

  1. ACB

  2. DLI

  3. BMP

  4. MPP

Show answer
Correct Option: B
Explanation:

To answer the question, the user needs to know the basic concepts of IMS, including the different interfaces used to connect the program to the Database in IMS.

Each option is explained below:

A. MPP: This option stands for Message Processing Program, which is not the correct interface used to connect the program to the Database in IMS.

B. ACB: This option stands for Access Control Block, which is not the correct interface used to connect the program to the Database in IMS.

C. DLI: This option stands for Data Language Interface, which is the correct interface used to connect the program to the Database in IMS. It provides a high-level interface for accessing IMS databases.

D. BMP: This option stands for Batch Message Processing, which is not the correct interface used to connect the program to the Database in IMS.

Therefore, the answer is: C. DLI
