SAP system performance problems
I´m trying to understand something about how and what can be done to improve our SAP system performance.
First of all this is a SAP ERP system that is installed in a windows server 2003 on a MS SQL Server database (in a cluster - cluster administration). We noticed that the performance of this SAP system is not the better and some users told us that some actions during the transactions are slow. The two servers (two cluster nodes) have a lot of RAM memory and also page file so I believe this problems are not related with this particulary things.
Can you told/teach me how can I check and measure if the system are with some problems!? Which transactions I must check to make this analysis and how can I correct/improve this situation?
Can you tell me please some tips regarding this type of problems?
