Performance Problems after a system copy

[Former Member]

Hello,

I did a SAP migration (homogeneous system copy) to a new server (windows server 2012 (R2)) some weeks ago. But since then all sap users are complaining with the performance of this SAP system. This is a SAP ERP 6.0 and the new server has 24Gb of RAM with 8 processors.

The database is an Oracle database 11.2 g (11.2.0.4). I set/adjust all the oracle parameters as it described in the recommendations in sap note 1431798 (Oracle 11.2.0: Database Parameter Settings).

How can I check if the system is slow or not? For example, in ST22 I don´t have any shortdumps... also in SM21.

In ST02 I see the following values:

I also set some SAP parameters some weeks ago but I don´t know exactly if I set well or not some parameters, this is, if the values are good/fit or not for this type of system:

I also checked the ST03n and this what I see the information for this month:

Can you help me to understand if I can change something in way to increase the performance of this SAP system!?

Hi Samid,

Addtionally, if possible, please compare the SAP and DB instance parameters with source system and make corresponding adjustments.
