BP,

What you are asking falls somewhat into the realm of Black Magic. Will you see a decrease in resource requirements from Multi Threaded Server (MTS) which is what I believe your asking. Possibly. It depends on the total number of connections to your database and the type of transaction these connections represent. MTS works well for database with a LARGE number of constant connections, like > 100, that process very short transactions. If these are batch types of transactions that process a large number of rows at a time then MTS is not for you. One item that you may have to weigh carefully is what level of delay can you tolerate in processing a transaction? The reason is that if a transaction request comes in and there is no shared server available to process it then it will wait either for a server to free up or Oracle to start a new one, which is NOT a guarantee. In using MTS I've found the kernel's load balancing algorithms (those that control the birth and death of shared servers) to be somewhat erratic and unpredictable.

Hi List ,
Is there any way I can make shared connectiuon explicitely . When I am looking at v$session I am finding tons of JDBC connection which are dedicated . Can I expect some performance gain or low resource requirement out of this if I make these dedicated connections to shared .
Thanks ,
Bp
