What is Weblogic multi-tiered JDBC driver? What is the difference between common JDBC and multi-tiered JDBC?
posted 12 years ago
A Mutitier JDBC Driver decorates (wraps) an existing JDBC Driver to provide additional functionality. For example, the WebLogic RMI Driver wraps a JDBC Datasource to allow remote access to JDBC Connections. This driver is used internal by WebLogic to access all Datasources and TxDatasources configured through the Admin console. Another example, is the WebLogic JTS Driver whichs wraps a standard JDBC Datasource to provide support for distributed transactions.
