SYSTEM AND METHOD FOR PROVIDING SESSION AFFINITY AND IMPROVED CONNECTIVITY IN A CLUSTERED DATABASE ENVIRONMENT |
摘要 |
<p>A clustered database environment includes multiple database instances that appear as one server. An application server can use a data source and connection pools to connect with the clustered database. A notification service broadcasts notifications describing state changes in the database instances, which are then used by the data source and connection pools to control access to the database instances. A data source configuration allows for specification of a preferred affinity policy. A session affinity policy is used to provide database instance affinity for database access made under the context of a web session, whereby database operations are directed to a particular instance for a period of time when the application may be performing multiple, related updates to a specific data set. Directing such operations to a single database instance can be used to improve application performance due to increased local cache utilization.</p> |
