Long description of Figure 2: Java program creating a single AS400 object and socket connection for the same iSeries server (rzahh552.gif)

found in IBM^® Toolbox for Java™: Managing connections

This figure illustrates that having multiple program objects share a single AS400 object reduces the number of connections and the amount of resource used on the system.

Description

The figure is composed of the following:

• A rectangle on the left represents a Java program
• A rectangle on the right represents an iSeries™ server
• A small circle between the rectangles represents a single AS400 object created by the Java program that connects to the iSeries server

The Java program (the left rectangle) contains several kinds of objects that use the AS400 object. Lines from these program objects connect to the AS400 object (the small circle).

Lines from the AS400 object connect to services contained in the iSeries server (the right rectangle). Each service represents a separate connection to the server. The services appropriately mirror the program objects:

• A data queue program object uses the AS400 object, which connects to a data queue server job
• Two integrated file system objects uses the AS400 object, which connects to a single file server job
• A command call object uses the AS400 object, which connects to a command call server job

All these program objects use the same AS400 object, which creates separate connections for each job that runs on the server. In this case, because the integrated file system objects use the same AS400 object, they share the same connection to and job on the server.
