The DBCP Component

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.
|
|
There are several Database Connection Pools already available, both
|
|
within Jakarta products and elsewhere. This Commons package provides
|
|
an opportunity to coordinate the efforts required to create and
|
|
maintain an efficient, feature-rich package under the ASF license.
|
|
The commons-dbcp package relies on code in the commons-pool package to
|
|
provide the underlying object pool mechanisms that it utilizes.
