An improved method, mechanism, and system for implementing, generating, and maintaining for implementing session pools is disclosed. A session in a session pool can be customized to with a specific set of affinities and attributes. Tags can be associated with the customized sessions. When a later request is made for a session having a set of desired characteristics, the tags can be used to search for and identify a session in the session pool having the requested characteristics. Also disclosed is a method, mechanism, and system for dynamic sizing of session pools.

Method and mechanism for implementing tagged session pools

A net traffic optimization method provides for clients and servers to communicate with each other over a busy network. Each client process will make an Oracle database service request that is recognized by a listener process in the servers. As each database instance comes up, it generates a globally unique instance identifier ('UII'). Each UII remains valid as long as the database instance that generated it is running. The same UII identifier is given to every client needing a connection to that particular instance. Client processes can simultaneously or sequentially connect to database instances, and must never see the same UII being used to identify two different instances.

Globally unique instance identification

In transferring data from/to a database server, the size of a network buffer used by a network layer is dynamically adjusted according to the call type and expected size of data to be transferred for the call. Due to such use of appropriate buffer size, throughput performance of the transfer may be enhanced.
