Optimize J2EE engine

[Former Member]

Dear experts,

our scenario is to run standard WebDynpro application(s), using JCO to connect to SAP and SQLJ for database access.

Can you suggest which services, applications etc. could be turned off so performance will be better?

Thanks in advance!

if u r using JCO , there are two ways to connect to Back End.

1)Direct Connection

2)Connection Pools

For direct Connection , each time connection is opened then execute back end RFCs and then closing the connection for a particular call to back end.

But when we use connection pool , if with same user ' , it is better.

this will help u.
