Q

Changing server mode from dedicated to shared

If we change the server mode from dedicated to shared, can the response time of end users improve? The database was initially in dedicated mode, but there are multiple users connecting to the same. What can be the effects on the existing database? Can this be more expensive in terms of resources?

Choosing to use shared server requires consideration of a number of factors. Chief among these is the number of concurrent database sessions. In general, you shouldn't use shared server unless you have at least hundreds of concurrent users; in such cases, the overhead of managing user processes and their memory can become a significant performance factor.
