Dear All,

We facing the same issue. can you pl send us the solution.

Thanks much.

[Former Member]

Yes Mr. Rohit I did, Unfortunately, that the buffer is reset due to system restart yesterday

for aix you should have:

ztta/roll_first = 1

ztta/roll_extension = 2000000000

ztta/roll_area = 6500000

heap dia and nondia can go to 4g

ES/SHM_SEGS_VERSION = 2

take the aix default for segment size (instead of 2m)..might be 4

it is very tough to give the recommendations based on just the profile parameters that you gave.

does the EWA report doesnt give you recommendations?they might have told you in what areas you are facing the perofrmance issues and you need to improve?

since when are you facing this performance issue,is it just today or you have been facing this for a long time

There is no easy way to tell.

You have go through the list of all of things to do for tuning.

One at a time and slowly rule out each item.

Couple of questions ??

Why do you have so many Dialog and Batch processes ??

Dont you have any Application servers ??

At first glance the Number of processes are too high

IN SM50 you need to click on the clock and see if all of the processes are being used and the time they have been used.

From you have mentioned would say the 2 vb processes are being used constantly

If that is the case then Would increase the number of vb and vb2 and decrease dialog accordingly

Did you find any pattern when performance is slow? How much swap is configured on this server?

[Former Member]

Yes Mr. Pravin, the average response times of the system is very poor,

Furthermore, that the number of transaction steps for Dialog process equal 212987 in an hour And for update process equal 86257 references to the EWA Report

Moreover, Iu2019m looking for any recommendation from sap for SAP application parameters in TCode: RZ10 , to distribute server resource

did you checked ST02 as said in my earlier post

[Former Member]

Much Cleaner post this time. But you still haven't mentioned what you meant by performance Issue.

Any more specifics about the issue ?? General system slowdown and so on

[Former Member]

Hello Ahmed,

Go to ST02 buffers and check if there are too many red entries on the screen,if yes let us know only those red entries
