Questions and Answers
- 1.
Does a root segment exist without child segment?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A root segment refers to the main or initial segment of a structure or system. In most cases, a root segment does exist without any child segments because it is the starting point or base of the structure. Child segments are typically derived or connected from the root segment, but it is possible for the root segment to exist independently without any child segments attached to it. Therefore, the answer "True" is correct.Rate this question:

A PSB can exists without a single PCB?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. A PSB (Program Specification Block) cannot exist without a single PCB (Program Control Block). The PSB contains information about the program's specifications, such as the program name, type, and location. The PCB, on the other hand, contains information about the program's execution, such as the program's status, resources allocated, and execution priority. Without a PCB, the PSB would not have the necessary information to execute the program correctly.Rate this question:

How many DLI calls can we give in a program?
- A.
10
- B.
256
- C.
255
- D.
No limit depending on memory limitation
Correct Answer
D. No limit depending on memory limitationExplanation
The correct answer is "No limit depending on memory limitation" because the number of DLI calls that can be made in a program is not restricted by any specific number. The limit is determined by the available memory in the system. As long as there is enough memory to store the necessary data for each DLI call, there is no set maximum limit on the number of calls that can be made.Rate this question:

In a Logical relatioship, a segment can exists with multiple parents. Justify your answer?
- A.
Parents are from the same database
- B.
Parents are from multiple data bases
- C.
A child segment can have more than one parent. This is possible only with outside databases.
- D.
None
- E.
All of the above
Correct Answer
C. A child segment can have more than one parent. This is possible only with outside databases.Explanation
A child segment can have more than one parent, which means it can be related to multiple parent segments. This is possible only with outside databases, as parents from the same database would create a circular relationship. Therefore, the correct answer is that a child segment can have more than one parent, and this is possible only with outside databases.Rate this question:

The following IMS status codes,my friend has been asked in an interview. Are you support him thease are related to SSA? AU-SSA length exceeds maximum length AH-Invalid SSA in insert AJ-SSA specified for the call is invalid AK-Field name incorrectly coded for SSA
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given IMS status codes (AU, AH, AJ, AK) are related to SSA (Subsystem Attach) in IMS. These codes indicate different errors or issues related to SSA. "AU-SSA length exceeds maximum length" suggests that the length of the SSA provided is longer than the maximum allowed length. "AH-Invalid SSA in insert" indicates that an invalid SSA was provided during an insert operation. "AJ-SSA specified for the call is invalid" signifies that the SSA specified for the call is invalid. "AK-Field name incorrectly coded for SSA" implies that the field name in the SSA is incorrectly coded. Therefore, the statement "The following IMS status codes are related to SSA" is true.Rate this question:

What kind of error/Status codes you will get during IMS deadlock?
- A.
GG, U0102
- B.
FH, U0777
- C.
GB, U476
- D.
GC,U551
Correct Answer
B. FH, U0777Explanation
During an IMS deadlock, the FH, U0777 error/status code will be received. This code indicates that a deadlock condition has occurred in the IMS system. Deadlock refers to a situation where two or more transactions are waiting for each other to release resources, resulting in a state of deadlock where no progress can be made. The U0777 code specifically signifies a deadlock timeout, indicating that the deadlock detection mechanism has identified a deadlock and has timed out waiting for it to be resolved.Rate this question:

- A.
256
- B.
255
- C.
5
- D.
None
Correct Answer
B. 255Explanation
The correct answer is 255 because in a single IMS database, there can be a maximum of 255 secondary indexes. Secondary indexes are used to improve the performance of database queries by allowing faster access to specific data. IMS databases can have multiple secondary indexes, but the maximum limit is 255.Rate this question:

Where we use Fast path databases, and two examples of those?
- A.
High transaction rate is involved. DEDB and MSDB. VSAM is the only access methos.
- B.
Less transaction rate is involved
- C.
Large data is involved
- D.
None
Correct Answer
A. High transaction rate is involved. DEDB and MSDB. VSAM is the only access methos.Explanation
Fast path databases are used when there is a high transaction rate involved. Two examples of fast path databases are DEDB and MSDB. The only access method supported by these databases is VSAM. This means that when there is a need for fast access to data and a high volume of transactions, these databases are used with VSAM as the access method.Rate this question:

DBRC is set to on when?
- A.
Batch production jobs
- B.
Testing jobs
- C.
Online
- D.
Both online and batch production
Correct Answer
D. Both online and batch productionExplanation
DBRC (Database Recovery Control) is set to "on" for both online and batch production jobs. This means that DBRC is enabled and active for both types of jobs. DBRC is a feature in mainframe systems that provides control and management of database recovery processes. By having it set to "on" for both online and batch production, it ensures that database recovery is available and managed for both types of jobs, whether they are executed online or as part of a batch production process.Rate this question:

How many places we need to give PCB in a program?
- A.
2 places
- B.
1 Only in Entry statement
- C.
In each DLI call
- D.
None
Correct Answer
B. 1 Only in Entry statementExplanation
In a program, we only need to give PCB (Program Control Block) in the entry statement. The PCB contains information about the program, such as its name, size, and location in memory. It is necessary to provide the PCB in the entry statement to ensure that the program is properly initialized and executed. Giving the PCB in each DLI (Device Level Interface) call or not giving it at all would be incorrect as it would lead to errors or incomplete program execution.Rate this question:

My friend told me, giving qualified SSA in DLI call is just like Indexing. Can you support him and why?
- A.
Yes- In SSA we give which field we are going to retrieve. So it acts as a Index.
- B.
No- I do not support
- C.
No- Any SSA we can give, that is index
- D.
None
Correct Answer
A. Yes- In SSA we give which field we are going to retrieve. So it acts as a Index.Explanation
The given answer is correct because in SSA (Single Static Assignment) form, each variable is assigned only once and is given a unique name. This unique name acts as an index to identify the specific field or value that we are retrieving. Therefore, giving qualified SSA in DLI call can be considered similar to indexing.Rate this question:
