Very high response time

[Former Member]

Hi,

We are using 64 bit kernel.

OS is windows 2003 server with service pack 2. and the db is MSSQLSRV 9.0.3042

Our system is 24GB RAM with virtual momory of 72 GB.

And there are 3 systems running.

R3 Development and Quality and BW development.

We have set PHYS_MEMSIZE = 4096 for R3 develpment and BW development

and for R3 quality PHYS_MEMSIZE = 6192

We have set the profile parameter as per the SAP Note Note 88416 - Zero

administration memory management as of 4.0A/ Windows.

But still the response time is more for CPU. The CPU takes 80% of the total response time 1300MS.

But once we restart the server at the OS level the total response time decreases to 600ms. After 1 or two days it goes back to 1300ms.

Please help me.

Best Regards,

Sriram.S

I would recommend that you review SAP Note#1009297.

If the symptons described in that note are occuring then this can also cause a high CPU time, in this case obtain the KB from Microsoft and apply.

Hi All,

All the servers are running on the same host. More over i have implemented the note Note 1009297 - Windows Server 2003 Family: High Paging Rates.

But still i am facing the same problem.

Please help.

Hi Sriram,

It might be that at all the three servers standard background jobs are running. 3 Instance on single server .. surely need high hardware resource.

Hello Sriram,

are all the 3 systems running on same server??then you should expect a real high CPU utilization
