All the shared server processes monitor the common queue When a statement arrives on the common queue, the first available shared server picks it up From then execution proceeds through the usual parse-bind-execute cycle, but when it comes to the fetch phase, it is impossible for the shared server to fetch the result set back to the user process: there is no connection between the user process and the shared server So instead, the shared server puts the result set onto a response queue that is specific to the dispatcher that received the job in the first place Each dispatcher monitors its own response queue, and whenever any results are put on it, the dispatcher will pick them up and fetch them back to the user process that originally issued the statement Figure 4-11 depicts three user processes making use of shared server mode User processes 1 and 2 try to connect to an instance or service and are handed over to Dispatcher 1 by the listener, while user process 3 interacts with the instance via Dispatcher 2

A B C D E F G L M N O P User process 1 submits a statement for execution Dispatcher 1 places the statement onto the common queue A shared server process picks up the statement from the common request queue, parses it, executes it, and generates a result set The shared server places the result set in Dispatcher 1 s response queue Dispatcher 1 fetches the result set from its response queue Dispatcher 1 returns the results to User process 1 These steps are identical to steps A F but apply to User process 2 Note that Dispatcher 1 services both these user processes User process 3 submits a statement for execution Dispatcher 2 places the statement onto the common queue A shared server process picks up the statement from the common request queue, parses it, executes it, and generates a result set The shared server places the result set in Dispatcher 2 s response queue Note that this shared server process could be the very same process that performed preceding steps C, I, O, D and J Dispatcher 2 fetches the result set from its response queue Dispatcher 2 returns the results to User process 3

A result of the mechanism of dispatchers and queues is that any statement from any user process could be executed by any available shared server This raises the question of how the state of the session can be maintained It would be quite possible

for a user process to issue, for example, a SELECT FOR UPDATE, a DELETE, and a COMMIT In a normal dedicated server connection, this isn t a problem because the PGA (which is tied to the one server process that is managing the session) stores information about what the session was doing, and therefore the dedicated server will know what to COMMIT and what locks to release The PGA for a dedicated server session will store the session s session data, its cursor state, its sort space, and its stack space But in the shared server environment, each statement might be picked off the common queue by a different shared server process, which will have no idea what the state of the transaction is To get around this problem, a shared server session stores most of the session data in the SGA, rather than in a PGA Then whenever a shared server picks a job off the common queue, it will go to the SGA and connect to the appropriate block of memory to find out the state of the session The memory used in the SGA for each shared server session is known as the user global area (the UGA) and includes all of what would have been in a PGA with the exception of the session s stack space This is where the memory saving will come from Oracle can manage memory in the shared pool much more effectively than it can in many separate PGAs The part of the SGA used for storing UGAs is the large pool This can be configured manually with the large_pool_size parameter, or it can be automatically managed EXAM TIP In shared server, what PGA memory structure does not go into the SGA The stack space
