jakarta-commons-dbcp - Jakarta Commons DataBase Pooling Package
- Description:
Many Jakarta projects support interaction with a relational
database. Creating a new connection for each user can be time
consuming (often requiring multiple seconds of clock time),
in order to perform a database transaction that might take
milliseconds. Opening a connection per user can be unfeasible
in a publicly-hosted Internet application where the number of
simultaneous users can be very large. Accordingly, developers
often wish to share a "pool" of open connections between all
of the application's current users. The number of users actually
performing a request at any given time is usually a very small
percentage of the total number of active users, and during
request processing is the only time that a database connection
is required. The application itself logs into the DBMS, and
handles any user account issues internally.
