Which command is used to save the dataset in view mode ?

  1. zf.zl

  2. repl

  3. repl.zf.zl

  4. replace


Correct Option: C

AI Explanation

To answer this question, you need to understand the commands used to save a dataset in view mode.

Let's go through each option to understand why it is correct or incorrect:

Option A) zf.zl - This option is incorrect because the command "zf.zl" is used to save a dataset in write mode, not in view mode.

Option B) repl - This option is incorrect because the command "repl" is used to replicate a dataset, not to save it in view mode.

Option C) repl.zf.zl - This option is correct. The command "repl.zf.zl" is used to save a dataset in view mode. The "repl" command is used to replicate the dataset, and the "zf.zl" command is used to save it in view mode.

Option D) replace - This option is incorrect because the command "replace" is used to replace values in a dataset, not to save it in view mode.

The correct answer is Option C) repl.zf.zl. This option is correct because it combines the "repl" command to replicate the dataset and the "zf.zl" command to save it in view mode.

Which attribute of PDS should be modified so that it can have members within?

  1. Block size

  2. Directory blocks

  3. Space

  4. Record Format


Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of a Partitioned Dataset (PDS) and its attributes.

A Partitioned Dataset (PDS) is a file organization structure used in mainframe systems, such as IBM's z/OS. It is similar to a directory or folder in other operating systems, where it can contain multiple members or files.

The attribute of a PDS that should be modified to allow it to have members within is the "Directory blocks" attribute.

Option A) Block size - This option is incorrect because the block size refers to the size of the physical storage blocks used to store the data within the dataset. It does not affect the ability to have members within the dataset.

Option B) Directory blocks - This option is correct because the directory blocks attribute determines the number of blocks reserved for storing the directory information, which includes the list of members within the PDS. By increasing the number of directory blocks, you can allow the PDS to have more members.

Option C) Space - This option is incorrect because the space attribute determines the amount of storage allocated for the entire PDS, including the data and directory blocks. It does not directly affect the ability to have members within the dataset.

Option D) Record Format - This option is incorrect because the record format attribute determines the format of the individual records within the dataset. It does not affect the ability to have members within the dataset.

Therefore, the correct answer is option B) Directory blocks. By modifying the directory blocks attribute, you can allow a PDS to have members within.

ASM

  1. Advanced Storage Manager

  2. Auxiliary Storage Manager

  3. Automatic Storage Manager

  4. Adaptive Sequence Manager


Correct Option: B

AI Explanation

To answer this question, we need to understand the acronym ASM and its possible meanings. Let's go through each option to determine the correct answer:

Option A) Advanced Storage Manager - This option is incorrect because ASM does not commonly stand for Advanced Storage Manager. There is no widely recognized definition of ASM as Advanced Storage Manager.

Option B) Auxiliary Storage Manager - This option is correct because ASM commonly stands for Auxiliary Storage Manager. An Auxiliary Storage Manager is responsible for managing the storage resources of a computer system, including secondary storage devices such as hard drives or tape drives.

Option C) Automatic Storage Manager - This option is incorrect because ASM is not commonly used to represent Automatic Storage Manager. Automatic Storage Manager is a specific storage management feature in Oracle Database that simplifies the management of Oracle database files.

Option D) Adaptive Sequence Manager - This option is incorrect because ASM is not typically used to represent Adaptive Sequence Manager. Adaptive Sequence Manager is not a widely recognized term or acronym in the context of storage management.

The correct answer is B) Auxiliary Storage Manager. This option is correct because ASM commonly stands for Auxiliary Storage Manager, which refers to the management of secondary storage devices in a computer system.
