    Does a root segment exist without child segment?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    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.

    Where we use Fast path databases, and two examples of those?

    • High transaction rate is involved. DEDB and MSDB. VSAM is the only access methos.

    • Less transaction rate is involved

    • Large data is involved

    • 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.

    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

    • True

    • False

    Correct Answer
    A. True
    Explanation
    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.

    A PSB can exists without a single PCB?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    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.

    The flow of a transaction execution in IMSDC is ==>  MOD- > DIF- >DOF- >MID

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In IMSDC, the flow of a transaction execution follows the sequence MOD- DIF- DOF- MID. This means that the transaction goes through the stages of modification, differentiation, distribution, and finally mid-office processing. Therefore, the statement "The flow of a transaction execution in IMSDC is MOD- DIF- DOF- MID" is true.

    How many databases involved in IMS?

    • 3- Fast Path, Full function, HLADB

    • 1- Fast Path

    • 2- Full function and HLADB

    • None

    Correct Answer
    A. 3- Fast Path, Full function, HLADB
    Explanation
    IMS (Information Management System) involves three types of databases: Fast Path, Full function, and HLADB. Fast Path is a database that is optimized for high-speed transaction processing. Full function database provides a complete set of features for managing and manipulating data. HLADB (High Level Application Database) is a database that supports hierarchical data structures. Therefore, the correct answer is 3- Fast Path, Full function, HLADB.

     How many secondary indexes are possible in a single IMS database?

    • 256

    • 255

    • 5

    • None

    Correct Answer
    A. 255
    Explanation
    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.

    DBRC is set to on when?

    • Batch production jobs

    • Testing jobs

    • Online

    • Both online and batch production

    Correct Answer
    A. Both online and batch production
    Explanation
    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.

    A PSB is defined that TYPE=GSAM. Can you identify this relates to which PCB?

    • DB PCB

    • IO PCB

    • Alternate PCB

    • GSAM PCB

    Correct Answer
    A. GSAM PCB
    Explanation
    The given information states that a PSB is defined with TYPE=GSAM. This suggests that the PSB is related to a GSAM PCB. The TYPE parameter in the PSB definition is used to specify the type of PCB associated with it. Therefore, the correct answer is GSAM PCB.

    How many DLI calls can we give in a program?

    • 10

    • 256

    • 255

    • No limit depending on memory limitation

    Correct Answer
    A. No limit depending on memory limitation
    Explanation
    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.

    How much data we can store in HLADB databases?

    • 1 GB

    • 1 TB

    • 2 GB

    • None

    Correct Answer
    A. 1 TB
    Explanation
    HLADB databases can store up to 1 TB of data. This means that the maximum amount of data that can be stored in HLADB databases is 1 terabyte.

  • 15. 

    How many places we need to give PCB in a program?

    • 2 places

    • 1 Only in Entry statement

    • In each DLI call

    • None

    Correct Answer
    A. 1 Only in Entry statement
    Explanation
    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.

     What kind of error/Status codes you will get during IMS deadlock?

    • GG, U0102

    • FH, U0777

    • GB, U476

    • GC,U551

    Correct Answer
    A. FH, U0777
    Explanation
    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.

    In a Logical relatioship, a segment can exists with multiple parents. Justify your answer?

    • Parents are from the same database

    • Parents are from multiple data bases

    • A child segment can have more than one parent. This is possible only with outside databases.

    • None

    • All of the above

    Correct Answer
    A. 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.
