Configuring WebLogic Server 9.x JDBC

摘要

WebLogic Server 9.x provides database connectivity with data sources. A data source is a pool of database connections from which a connection can be obtained. A data source can be configured separately or as a multidatasource. A multi-data source is collection of data sources. A data source is configured with a JNDI binding. A DataSource object is obtained with a JNDI lookup. A Connection object can be obtained from a DataSource object with the getConnectionO method. WebLogic Server provides an administration console to configure a data source; WebLogic Server 9.x includes Type 4 JDBC drivers from DataDirect for DB2, Informix, Microsoft SQL Server, Sybase, and Oracle databases. JDBC drivers for other databases can be incorporated in the server by including the JAR files for the JDBC drivers in the server classpath.
