This section describes the connection URL format and how to create connection objects with the drivermanager class.
If you want to use the drivermanager class to create connection objects, you need to know how to make a connection URL that provides access information to the Oracle server. the Oracle connection URL for the thin clien
This article mainly describes how to greatly improve the performance of Oracle JDBC programs by using the connection and statement pool features. We generally use pool technologies, such as connection pool and statement pool, to significantly improve the performance of database-intensive applications, because this can achieve Object reuse, you do not need to spend time and resources to recreate objects.
