Object Swapping
Use
Swapping occurs when the buffer is full, and the SAP System has to load additional objects into the buffer. Objects in the buffer that were used the least recently are removed. In this context, the term “swap” means the objects removed from the buffer are lost and cannot be replaced until a new database access is performed (replacing what was lost).
There are two possible reasons for swapping
● There is no space left in the buffer data area
The buffer is too small. You should increase the buffer size.
● There are no directory entries left
Although there is enough space left in the buffer, no further objects can be loaded because the number of directory entries is limited.
For the Repository buffers (nametab buffers), the number of directory entries is determined by the number of entry counts, all other buffers have there own parameter for entries.
The parameter abap/programs is no longer used. You do not have to change it if you want to increase the program buffer. For all other buffers you have to change the number of directory entries accordingly to the change in buffer size.
