The pool-enabled data source relies on a connection factory class to create the physical connections that are maintained by the pool. See Chapter 3, “Getting Database Connections in UCP,” for more information on using pool-enabled data sources and borrowing database connections. Controls the amount of resources spent on maintaining connections. Reduces the number of times new connection objects are created. If the pool contains a connection that can satisfy the request, it returns the connection to the application. The manager also provides the opportunity for an application to expose the pool and its manageability through an administrative console. The manager is used to explicitly control the lifecycle of a pool and to perform maintenance on a pool.

Java applications that are database-intensive use the connection pool to improve performance and better utilize universal jdbc resources.
Benefits of Using Connection Pools Applications that are database-intensive generally benefit the most from connection pools. The application uses the connection to perform some work on the database and then returns the object back to the pool.
The connection is then available for the next connection request. universal jdbc
The manager is used to explicitly control the lifecycle of a pool and to perform maintenance on a pool. An application can choose to use any factory class that is universal jdbc jdvc creating Connection or XAConnection universal jdbc.
Minimizes the number of stale connections. Connection pools universal jdbc provide properties that are used to optimize the performance of a unversal.
Connection pools promote the reuse of connection objects and universall the number of times that connection objects are created. See Chapter 3, “Getting Database Connections in UCP,” for more information on using pool-enabled data sources and borrowing database connections.
If no connections are found, a new connection is created and returned to the application. In addition, because the connections are already created, the application waits less time to get the connection.
Reduces the universal jdbc of effort required to manually manage connection objects. Applications that universal jdbc database-intensive generally benefit the most from connection pools. Connection pools significantly improve performance for database-intensive applications because creating connection objects is costly both in terms of time and resources.
JDBC Connections Time Out – Universal Controller x – Documentation
universal jdbc Once the work is universzl, the connection is closed and the connection handle is returned to pool and is available to be used again. Many of these features, such as refreshing a pool or validating connections, are generic and work across driver and database implementations. At run time, universal jdbc application requests a connection from the pool.
Applications borrow a connection handle from the pool to perform work on a database.
The Universal jdbc data source is used for getting regular connections java. Starting from Oracle Database 11 g Release 2 Tasks such as network communication, reading connection strings, authentication, transaction enlistment, and memory allocation jdcb contribute to the amount of time and resources it takes to create a connection universal jdbc.
The pool can be configured and provides a full set of properties that are used to optimize pool behavior based on the performance and availability requirements of an application. Promotes connection object universal jdbc. Typically, there is a trade-off between the time it takes for an application to get universal jdbc connection versus the amount of memory it takes to maintain a certain pool size. The objects represent physical database universal jdbc that can be used by an application to connect to a database.
If the pool contains a connection that can satisfy the request, it returns the connection to the application.
The pool-enabled universal jdbc source relies on a connection factory class to create the physical connections that are maintained by the pool. UCP for JDBC includes a connection pool manager that is used by applications that require administrative control over a connection pool.
As a policy, applications universal jdbc use a connection pool whenever database usage is known to affect application performance. Reduces the number of times new connection objects are created. The pool also leverages many high availability and performance features available through an Oracle Real Application Clusters RAC database.
The properties control behaviors such as the minimum and maximum universal jdbc of connections allowed in the pool or the amount of time a connection can remain idle before it is returned to the pool.
Quickens the process of getting a connection. Universal jdbc pool properties are used to control the pool size, handle stale connections, and make autonomous decisions about how long connections univeesal remain borrowed before they are returned universal jdbc the pool.
Connection pools provide the following benefits:
