APO performance after replacing the application servers

28 Views

Hi,

We recently replaced all the APO production application servers(windows

2000) with new servers that aree windows 2003,The new servers are

having higher configuration compared to the old servers. There was no

change to the CI/DB server and they still run on OS400/DB400.After this

application server change we are observing the following issues :

1. The overall dialog performance in the application servers have come down drastically.Especially high db request time.

2. The CIF queue transfers from R/3 to APO have slowed considerably which are happening through the application servers.

I initially found the RZ12 was not having the new application servers in the server group and later included them. This improved the CIF transfers but still not to the normal performance levels. I also observed majority of the dialog processes doing sequential read in theapp servers. We would like to know if there are any specific steps tobe performed at the DB level after this hardware changes. Please

clarify.

Thanks,

Mahesh
