Buffer Parameter Increase???

Former Member

In one of the servers we are facing high number of swaps in the following buffers.

Program buffer (PXA)

CUA buffer (CUA)

Screen buffer (PRES)

Export/Import buffer (EIBUF)

To overcome this issue we have to increase the value in corresponding

Program buffer (PXA)

abap/buffersize

CUA buffer (CUA)

rsdb/cua/buffersize

Screen buffer (PRES)

zcsa/presentation_buffer_area

Export/Import buffer (EIBUF)

rsdb/obj/buffersize

My Question is how do I analyze how much Value should I increase for each of the Parameter.

Useful answers will be rewarded!

Hai,

you can increase the buffer size in RZ10 in instance profile

abap/buffersize by default you will get 300,000 you can increase up to 600,000

But you need to restart the system..

Hi Praveen,

You can analyze from ST02, there you will find what is allocated and current and max. used.

Hello,

swap of buffer is basically comes under perfomance tuning and parameterizations. check the "performance tuning guides" for details.

To get the actual values system required, generally we execute command,

sappfpar pf=<path of instance file parameter>
