Inefficient usage of JCO connections

22 Views

Hi,

SAP did a review on the portal that I mantain and wrote:

"Inefficient usage of JCo connections:

With the help of Wily Transaction Traces we could identify that for the initial startpage of a user (MSS) two JCo connections are opened within the same pool to the same backend. This is re-dundant as the data could be received over one connection. The effect is the double amount of JCo connections which means an additional usage of resources.

Each login consists of two connections into the backend. We observed when refreshing the page hitting either the F5 key or the enter key on the URL, the user is logged out of the portal and the backend system to be logged in again immediately.

This behaviour consumes J2EE and Backend resources unnecessarily. This behaviour was also observed in the productive environment."

I don't understand this point, can you help me ?

Thanks in advance.
