high swap rate

[Former Member]

Hi

In my Development System when i check Tune Summary (ST02) ,i could see Swap rate is high for some prarameters viz

Program buffer PXA

abap/buffersize 400000 kB Size of program buffer

abap/pxa shared Program buffer mode

Screen buffer PRES

zcsa/presentation_buffer_area 4400000 Byte Size of screen buffer

sap/bufdir_entries 2000 Max. number of buffered screens

Generic key table buffer TABL

zcsa/table_buffer_area 30000000 Byte Size of generic key table buffer

zcsa/db_max_buftab 5000 Max. number of buffered objects

Export/import buffer EIBUF

rsdb/obj/buffersize 4096 kB Size of export/import buffer

rsdb/obj/max_objects 2000 Max. number of objects in the buffer

rsdb/obj/large_object_size 8192 Bytes Estimation for the size of the largest object

rsdb/obj/mutex_n 0 Number of mutexes in Export/Import buffer

Swap rate for Export/import buffer is almost 120 swaps per day.

Moreover 2 instance are running on these server having 4gb RAM Capacity.

plz tell me to what extent i have to increase the size of these parameters so that swap rate comes down.

First tell us what SAP is actually running on the machine. Version? Number of users?

this is a general AS ABAP question, wrong forum.

But in order to answer it more information is needed.

on which OS is the server installed, if Linux or Windows 32 or 64 Bit.
