How many extents are possible for a VSAM file

technology mainframe

  1. 123 extents for a VSAM file.

  2. 113 extents for a VSAM file.

  3. 133 extents for a VSAM file.

  4. 143 extents for a VSAM file.

Show answer
Correct Option: A

AI Explanation

To answer this question, we need to understand the concept of extents in VSAM (Virtual Storage Access Method) files.

In VSAM, a file is divided into multiple extents. An extent is a contiguous block of storage allocated to a file. Each extent can contain a certain number of records.

The maximum number of extents that can be allocated to a VSAM file depends on the size of each extent and the total storage available.

Based on the information provided, the correct answer is: Option A) 123 extents for a VSAM file.

This option is correct because it states that a VSAM file can have 123 extents.

What does a disposition of (NEW,CATLG,DELETE) mean?

technology mainframe

  1. Indicates a new dataset and allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends.

  2. Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step abends.

  3. Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends.

  4. Indicates a new dataset and allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step not abends.

Show answer
Correct Option: C

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Indicates a new dataset and allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends. This option is incorrect. The correct disposition would be to catalog the dataset if the step is successful, not to allocate and catalog it.

Option B) Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step abends. This option is incorrect. The correct disposition would be to delete the dataset if the step abends, not if it is unsuccessful.

Option C) Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends. This option is correct. The disposition (NEW,CATLG,DELETE) indicates that the dataset is new and needs to be allocated. If the step is successful, the dataset should be cataloged. If the step abends (fails), the dataset should be deleted.

Option D) Indicates a new dataset and allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step not abends. This option is incorrect. The correct disposition would be to delete the dataset if the step abends (fails), not if it doesn't abend.

The correct answer is C. This option is correct because it accurately describes the disposition (NEW,CATLG,DELETE) as indicating a new dataset that needs to be allocated. If the step is successful, the dataset should be cataloged, and if the step abends (fails), the dataset should be deleted.
