DFDSS cannot be used to
-
Reduce DASD free space fragmentation
-
Copy or move data sets from one DASD device to another or dump
-
Restore backup copies of entire DASD volumes
-
Increase File storage
AI Explanation
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Reduce DASD free space fragmentation - DFDSS can be used to reduce DASD free space fragmentation. DFDSS (Data Facility Data Set Services) is a utility program in z/OS that provides various functions related to managing datasets and storage. It includes functions for managing free space on DASD (Direct Access Storage Device) by defragmenting free space.
Option B) Copy or move data sets from one DASD device to another or dump - DFDSS can be used to copy or move data sets from one DASD device to another or to create backups of datasets through a dump operation. These operations are commonly performed using the DFDSS utility.
Option C) Restore backup copies of entire DASD volumes - DFDSS can be used to restore backup copies of entire DASD volumes. It provides functions for backup and restore operations, allowing users to restore datasets or entire volumes from backup copies.
Option D) Increase File storage - DFDSS cannot be used to increase file storage. DFDSS primarily deals with managing datasets and storage, but it does not have the capability to increase the storage capacity of a file.
Based on the explanations above, the correct answer is D) Increase File storage. This option is incorrect because DFDSS cannot be used to increase file storage.

To solve this question, the user needs to know what FTP is and what parameters it uses. FTP (File Transfer Protocol) is a standard network protocol used to transfer files from one host to another over the Internet.
Now, let's go through each option and explain why it is right or wrong:
A. GET: This option is a valid FTP parameter. It is used to retrieve a file from a remote server.
B. PUT: This option is a valid FTP parameter. It is used to upload a file to a remote server.
C. EXIT: This option is not a valid FTP parameter. It is a command to exit the FTP client.
D. BYE: This option is a valid FTP parameter. It is used to terminate an FTP session.
Therefore, the answer is:
The Answer is: C
-
OPEN
-
RMDIR
-
OUT
-
GET
-
TERMINATE
-
DELETE
-
CLOSE
-
None of the above
To solve this question, the user needs to know about computer networking and the basic commands used to manage network connections.
Option A, TERMINATE, is not a valid command to terminate a connection with another computer. There is no such command in computer networking.
Option B, DELETE, is not a valid command to terminate a connection with another computer. This command is used to delete files or directories, not network connections.
Option C, CLOSE, is the correct command to terminate a connection with another computer. This command is used to close a network connection or a file stream.
Option D, None of the above, is incorrect because option C, CLOSE, is the correct command to terminate a connection with another computer.
Therefore, the answer is: C. CLOSE.

To solve this question, the user needs to understand the program specification and the field length for the status code.
Option A: 4. This option might be correct for some programs, but it does not match the specified program in the question.
Option B: 8. This option might be correct for some programs, but it does not match the specified program in the question.
Option C: 6. This option might be correct for some programs, but it does not match the specified program in the question.
Option D: 2. This option is the correct answer according to the program specification given in the question.
Therefore, the answer is: The Answer is D.
-
PLAN Name in which the DB2 program has to be bound
-
Collection name in to which the program has to be bound
-
Database Name
-
Dataset in which the DB2 program resides
To answer this question, the user needs to have knowledge of DB2 and the process of binding a program.
The PLAN parameter in DB2 refers to the plan name in which the DB2 program has to be bound.
Option A is correct because the PLAN parameter specifies the name of the plan to which the program should be bound during the BIND process.
Option B is incorrect because the collection name refers to a set of related objects in DB2, and it is not related to the PLAN parameter.
Option C is incorrect because the database name refers to the name of the database in which the tables and other objects used by the program are located, and it is not related to the PLAN parameter.
Option D is incorrect because the dataset refers to the physical location of the program code, and it is not related to the PLAN parameter.
Therefore, the correct answer is:
The Answer is: A. PLAN Name in which the DB2 program has to be bound
-
Authentication failure
-
SELECT statement has resulted in retrieval of more than one row
-
Generated when the consistency tokens in the DBRM and the load module are different
-
Resource Unavailable
To understand this question, the user needs to know what SQL is and its error codes. SQL (Structured Query Language) is a programming language used to manage and manipulate relational databases. SQL error codes are used to indicate any errors or problems that occur during SQL processing.
Option A: Authentication failure. This error occurs when a user provides incorrect login credentials while trying to access the database. However, SQL code -818 is not related to authentication failure.
Option B: SELECT statement has resulted in retrieval of more than one row. This error occurs when a SELECT statement is expected to return only one row, but it returns more than one row. However, SQL code -818 is not related to this error.
Option C: Generated when the consistency tokens in the DBRM and the load module are different. This error occurs when there is a mismatch between the consistency tokens in the DBRM (Database Request Module) and the load module. Consistency tokens are used to ensure that the DBRM and the load module are in sync. SQL code -818 is related to this error.
Option D: Resource Unavailable. This error occurs when the required resources are not available in the system. However, SQL code -818 is not related to this error.
Therefore, the correct answer is:
The Answer is: C. Generated when the consistency tokens in the DBRM and the load module are different.
Which of the following Environment cannot access DB2?
-
TSO
-
CICS
-
IMS
-
ENDEVOUR
To solve this question, the user needs to have basic knowledge of mainframe environments and their capabilities to access DB2.
Now let's go through each option and explain why it is right or wrong:
A. TSO - This environment can access DB2. TSO (Time Sharing Option) is an interactive dialog with the operating system, which provides an interface for the user to interact with the system. DB2 can be accessed through TSO environment using SPUFI and QMF tools.
B. CICS - This environment can access DB2. CICS (Customer Information Control System) is a transaction processing system that can access DB2 databases to store and retrieve data.
C. IMS - This environment can access DB2. IMS (Information Management System) is a hierarchical database management system that can access DB2 databases using the DLI (Data Language Interface) module.
D. ENDEVOUR - This environment is a software change management tool and does not have the ability to access DB2.
Therefore, the correct answer is:
The Answer is: D. ENDEVOUR
