found in IBM® Toolbox for Java™: Managing connections
This figure illustrates how you can use a connection pool to manage your connections to an iSeries™ server.
The figure is composed of the following:
Inside the AS400ConnectionPool (the oval) are multiple connections. Each connection is an AS400 object, which is pictured as a small image of an iSeries server with a lightning bolt on it:
The top half of the circular arrow points from the AS400ConnectionPool (the oval) to the Java application (the rectangular image on the left). On the arrow is one of the connections from the pool, and one of the connection images in the connection pool is faded. This represents a connection from the connection pool being requested and used by the Java application.
The bottom half of the circular arrow points from the Java application to the connection pool. This represents the Java application returning the connection to the connection pool.
The single line that connects the iSeries server (the image on the right) to the AS400ConnectionPool (the oval) represents socket connections to the server.
