Ayur,

To address your first questions, need to

Dilalog WPs are in waiting state (no PRIV state)

CPU utilization

Database stats updated or not

Any net work related issue

Since your problem is not continuous investigating a). Operating System at that time will be useful.

ST03N response times analysis is the conclusion area whether the problem is related to OS, DB, Network etc.

Regarding your second query:

You can buffers as below

$SYNC This resets all buffers of the application server

$CUA This resets the CUA buffer of the application server

$TAB This resets the TABLE buffers of the application server

$NAM This resets the nametab buffer of the application server

$DYNP - the screen buffer of the application server

Check link: http://www.sap-basis-abap.com/bc/resetting-the-buffer-in-sap.htm

But before restting the buffers have a look at teh link below

Hope . . This may be helpful

Ayur,

Following checks may be useful

a. ST03, choose Performance Database -> goto - >profiles - > RFC profile

b .Analyse the output (Times) from the output of STAD (Mention the specific client in STAD)

c. Check any background jobs running for very long time

while less or no users on other (good condition clients), you can try below too

d. Increase the WP trace level, i think CTRLSHIFTF7 and check any useful info

e. Swich on the trace in ST05 and analyse the output

Hi,

If you're asking yourself this kind of question, you should urgently take a SAP administration course.

You can't get this knowledge and experience from forum questions because the answer will be :

Check transactions :

ST06, STAD, ST03, DB02, ST04, ST05 and so on....

Regards,

Olivier

What exactly did you check?

You can use "perfmon" on Windows to check performance data over some time. You can use ST06/OS07N.

Restart the instance
