Wich of the following SQL statements types always bypass the SAP table buffers?
- "Select Distinct" statements
- Open SQL statements
- "Select Single" statements
- Native SQL statements
- "Select for Update" statements
Correct Answer(s)

A. "Select Distinct" statements
A. Native SQL statements
A. "Select for Update" statements

Explanation

"Select Distinct" statements, Native SQL statements, and "Select for Update" statements always bypass the SAP table buffers. The "Select Distinct" statement retrieves only unique values from a table, and since it does not require any buffering, it bypasses the table buffers. Native SQL statements allow direct interaction with the database, bypassing any buffering mechanisms. "Select for Update" statements lock the selected rows for update, bypassing the table buffers to ensure data consistency. Therefore, these three types of SQL statements always bypass the SAP table buffers.

- To speed up context switches (roll in/ roll out)
- To decrease the sizer of the work porcess's local memory
- To prevent buffer swaps
- To prevent operating system paging
Correct Answer

A. To speed up context switches (roll in/ roll out)

Explanation

Parts of user context are stored in extended memory instead of local memory to speed up context switches. Context switches involve saving the current state of a process and loading the saved state of another process. By storing the user context in extended memory, the switching process becomes faster as the data can be accessed more efficiently. This helps in improving the overall performance of the system by reducing the time taken for context switches.

- Insuficient number of free processes
- SAP buffers (program, CUa or sceen) are too small
- CPU bottleneck
- Not enough Extended Memory or space in the Roll Buffer avaible
Correct Answer

A. Insuficient number of free processes

Explanation

A high 'wait time' in a system is most likely caused by an insufficient number of free processes. When there are not enough processes available to handle the workload, tasks have to wait in a queue, leading to increased wait times. This can result in slower system performance and delays in executing tasks.

Where and when is ABAP heap memory allocated?
- In teh local memory of the work process, when the work process is started
- In teh local memory of the work process, when required
- In shared memory, when required
- In shared memory, when the system started
Correct Answer

A. In teh local memory of the work process, when required

Explanation

ABAP heap memory is allocated in the local memory of the work process when required. This means that the memory is allocated dynamically as needed during the execution of the program. The work process is responsible for managing its own local memory and allocating heap memory when necessary to store data and objects. This allows for efficient memory usage as memory is only allocated when it is actually needed, and it is deallocated when it is no longer required.

3. SWAPS in transaction ST02 are an indication of high CPU utilization. Determine whether this statement is true or false.
- True
- False
Correct Answer

A. False

Explanation

This statement is false. SWAPS in transaction ST02 are not necessarily an indication of high CPU utilization. SWAPS, also known as page swaps or paging, occur when the operating system moves data from the main memory (RAM) to the secondary storage (hard disk) to free up space in RAM. This is done when the RAM is full or when the operating system decides to optimize memory usage. SWAPS can occur due to various reasons, such as insufficient RAM, memory leaks, or high memory usage by other processes. It is not directly related to CPU utilization.

- A) rdisp/wp_no_dia
- B) rdisp/wp_no_btc
- C) rdisp/wp_no_enq
- D) rdisp/dynamic_wp_check
Correct Answer

A. D) rdisp/dynamic_wp_check

Explanation

The correct answer is D) rdisp/dynamic_wp_check. This profile parameter affects the activation of dynamic work processes. When this parameter is set to a non-zero value, the system dynamically activates additional work processes based on the workload. This allows for better utilization of system resources and improved performance.

1. Virtual memory is made up of OS swap or page file and physical memory components. Determine whether this statement is true or false.
- True
- False
Correct Answer

A. True

Explanation

This statement is true. Virtual memory is indeed made up of the operating system's swap or page file and physical memory components. The swap or page file is a portion of the hard drive that the operating system uses as an extension of physical memory. It allows the operating system to temporarily store data that is not currently being used by programs in physical memory. When the data is needed again, it can be swapped back into physical memory. This helps to optimize memory usage and allows for efficient multitasking.

2. In transaction ST02, there is a problem if there is a lot of swapping in the SAP buffers.Determine whether this statement is true or false.
- True
- False
Correct Answer

A. True

Explanation

In transaction ST02, there can indeed be a problem if there is a lot of swapping in the SAP buffers. Swapping refers to the process of moving data between the main memory and the disk, and excessive swapping can lead to performance issues and slower response times. Therefore, it is true that there can be a problem if there is a lot of swapping in the SAP buffers.

3. Which of the following parameters lead to the allocation of heap memory for dialog processes? Choose the correct answers.
- A) em/initial_size_MB
- B) em/max_size_MB
- C) rdisp/roll_SHM
- D) Ztta/roll_extension
Correct Answer(s)

A. B) em/max_size_MB
A. D) Ztta/roll_extension

Explanation

The correct answers for the question are B) em/max_size_MB and D) Ztta/roll_extension. These parameters are responsible for allocating heap memory for dialog processes. em/max_size_MB determines the maximum heap memory size in megabytes that can be allocated for a dialog process, while Ztta/roll_extension determines the size of the extended memory that can be used for roll area in dialog processes.
