In the program specification Block the field length for the segment name is

  1. 4

  2. 8

  3. 6

  4. 12


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of field length in a program specification.

Field length refers to the maximum number of characters allowed in a particular field within a program specification. In this case, we are specifically looking at the field length for the segment name.

The correct answer is B) 8. This means that the segment name field in the program specification can have a maximum length of 8 characters.

  1. System managed Buffering

  2. System managed buffer

  3. Service managed Buffering

  4. None of the above


Correct Option: A
  1. increases the number of Index buffers for random access

  2. increases the amount of virtual storage

  3. increases the number of Data buffers for sequential access

  4. All of the above


Correct Option: A
  1. Copy the data of VSAM file which has to be REORG into another dataset

  2. Delete the current VSAM dataset

  3. Define the VSAM dataset.

  4. All of the above


Correct Option: D
Explanation:

To answer this question, the user needs to have knowledge of VSAM (Virtual Storage Access Method) and the process of VSAM REORG.

The correct answer is:

D. All of the above

Explanation:

The process of VSAM REORG involves the following steps:

A. Copy the data of VSAM file which has to be REORG into another dataset: This step involves backing up the data in the VSAM file to another dataset before the REORG process can begin. This ensures that the data is not lost in case the REORG process fails.

B. Delete the current VSAM dataset: Once the backup is complete and verified, the original VSAM dataset can be deleted.

C. Define the VSAM dataset: After the original dataset has been deleted, a new VSAM dataset can be defined with the same name and attributes as the original dataset.

Therefore, all of the options listed above are correct steps that are involved in the process of VSAM REORG.

  1. for Backup/Recovery

  2. for increasing the speed

  3. for file backup

  4. All of the above


Correct Option: A
  1. Can only be used for VSAM datasets

  2. Dataset created by EXPORT command cannot have a sequential organization

  3. Dataset created by the IMPORT step is not processed until it has gone through corresponding EXPORT step

  4. Dataset created by EXPORT command can only have a sequential organization


Correct Option: A
  1. INFILE(ddname) | OUTDATASET(dsname)

  2. OUTFILE(ddname)| INDATASET(dsname)

  3. INFILE(ddname) | INDATASET(dsname)

  4. OUTFILE(ddname)| OUTDATASET(dsname)


Correct Option: D
  1. ERASE / NOERASE

  2. INHIBITSOURCE / NOINHIBITSOURCE

  3. NOINHIBITSOURCE / INHIBITSOURCE

  4. TEMPORARY / PERMANENT


Correct Option: C
  1. Write only Mode

  2. Read only Mode

  3. Read Write Mode

  4. All of the above


Correct Option: B
  1. Write only Mode

  2. Read only Mode

  3. Read Write Mode

  4. All of the above


Correct Option: B
  1. Write only Mode

  2. Read only Mode

  3. Read Write Mode

  4. All of the above


Correct Option: B
  1. ERASE operation is complete

  2. NOERASE operation is complete

  3. IMPORT operation is complete

  4. EXPORT operation is complete


Correct Option: C
  1. ERASE operation is complete

  2. NOERASE operation is complete

  3. IMPORT operation is complete

  4. EXPORT operation is complete


Correct Option: D
  1. Control Interval

  2. Cascade Interval

  3. Record Mode

  4. None of the above


Correct Option: C
Explanation:

To solve this question, the user needs to know about the CIMODE parameter in mainframe systems.

The answer is: C. Record Mode

Explanation:

The CIMODE parameter is used in IBM mainframe systems to specify the mode of processing for the target dataset. It can have one of the following values:

  • CI (Control Interval) mode: This mode processes the target dataset in control interval format. Control intervals are groups of records that are read and written as a single unit. This mode is useful for datasets with a high number of records.

  • CA (Cascade) mode: This mode processes the target dataset in cascade mode, which means that records are read and written in groups of control areas. Control areas are groups of control intervals that are read and written as a single unit. This mode is useful for datasets with a high number of control intervals.

  • Record mode: This mode processes the target dataset in record mode, which means that records are read and written one at a time. This mode is useful for datasets with a low number of records.

Since the question asks which mode allows the processing of the target dataset in a record mode, the correct answer is C. Record Mode. Option A is incorrect because it refers to control interval mode, and option B is incorrect because it refers to cascade mode. Option D is incorrect because one of the above options is correct.

  1. INTOEMPTY

  2. OBJECTS

  3. Only b

  4. Both a and b


Correct Option: D
Explanation:

To solve this question, the user needs to have knowledge of the IMPORT command in SQL.

The correct answer is:

D. Both a and b

Explanation:

The IMPORT command is used to import data from an external file into a SQL database. The IMPORT command has several parameters, one of which is the "PARAMETERS" parameter. The "PARAMETERS" parameter has several subcommands, including "INTOEMPTY" and "OBJECTS".

  • The "INTOEMPTY" subcommand is used to import data into an empty table.
  • The "OBJECTS" subcommand is used to import data into an existing table.

Therefore, option D is correct because both subcommands "INTOEMPTY" and "OBJECTS" are subcommands of the IMPORT parameter.

  1. IMPORT INFILE(DD1) OUTFILE(DD2) IEMPTY

  2. IMPORT INFILE(DD1) OUTFILE(DD2) INTOEMPTY

  3. IMPORT INFILE(DD1) OUTFILE(DD2) IETY

  4. IMPORT INFILE(DD1) OUTFILE(DD2) EMPTY


Correct Option: A
  1. Reduce DASD free space fragmentation

  2. Copy or move data sets from one DASD device to another or dump

  3. Restore backup copies of entire DASD volumes

  4. Increase File storage


Correct Option: D
