-
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.Rate this question:

Correct Answer(s)
A. A) Tables that are seldom changed.
A. C) Customizing data.Explanation
Table buffering is recommended for tables that are seldom changed and for customizing data. Table buffering helps improve performance by storing frequently accessed data in memory, reducing the need to access the database. This is particularly beneficial for tables that are not frequently updated, as it allows for faster retrieval of data. Additionally, buffering customizing data can help improve the performance of applications that rely on this data for customization purposes.Rate this question:

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 requiredExplanation
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.Rate this question:
