Oracle Java Database Connectivity (JDBC) sharding data source enables Java connectivity to an Oracle Globally Distributed Database without requiring the application to provide a sharding key.

Using the JDBC sharding data source, you do not need to identify and build the sharding key and the super sharding key to establish a connection. The sharding data source scales out to distributed databases transparently because it does not involve any change to the application code.

To use the JDBC sharding data source, set the connection property oracle.jdbc.useShardingDriverConnection to true as shown here.

Properties prop = new Properties();
prop.setProperty("oracle.jdbc.useShardingDriverConnection", "true");

The default value of oracle.jdbc.useShardingDriverConnection is false.

See the Oracle Database JDBC Developer’s Guide for more information and examples.
