Multipools jdbc

WebLogic Server allows you to cluster JDBC objects, including data sources, connection pools and multipools, to improve the availability of cluster-hosted applications. Each JDBC object you configure for your cluster must exist on each managed server in the cluster—when you configure the JDBC objects, target them to the cluster.

Apr 22, 2003 Multipools can keep track of dead connection pools and can avoid selection of the dead connection pools. The multipool can check whether a connection pool has revived in the background. MultiPools can be created from the Administration Console in the following way: Open the WebLogic Administration Console and click JDBC. Click the link to MultiPools (located below the link to Connection Pools). Then on the page that appears on the right, click Configure a New JDBC MultiPool.

Then on the page that appears on the right, click Configure a New JDBC MultiPool. Each of the tabs on the screen is described next. JDBC application code should always close connections explicitly to derive the most benefit from pooling. When the application explicitly closes a connection, the pooling implementation can reuse the connection immediately. If the connection is not closed, other applications cannot reuse it. Later in this chapter we shall see how you can access a server-side JDBC pool using either a data source or one of WebLogic's wrapper JDBC drivers. 5.1.3 Multipools WebLogic also lets you set up a multipool a pool of multiple connection pools that then can be targeted to either a single server or a cluster.
