GCPM, connection pool management

The G&R Connection Pool Manager is a component of G&R Glink for Java™ Enterprise Edition that offers connection setup and pooling to Glink for Java™ API applications. Instead of clients having to set up and manage connections to Enterprise Information Systems themselves the Pool Manager offers a simple high-level API whereby clients can request working connections, use them, and release them back to the Pool Manager when finished with them.

The Pool Manager was designed with two different environments in mind:

Web server/Servlet container environment: where J2EE is either not present or not required. In this scenario, client components such as Java Server Pages and Servlets can use the Pool Manager to obtain working mainframe connections in a simple and consistent manner. A client can request several connections from different pools at the same time, allowing integration of several mainframe applications into a single client application.
Stand-alone environment: a desktop or server scenario where there's no Web server involved. In this environment a Java application can use the Pool Manager as a service library to obtain working mainframe connections. The application could act as a server for remote clients, or it could be a desktop client application. In either case the Pool Manager interface is the same.

The Pool Manager offers some of the same functionality as the J2EE Connector Architecture:

Multiplexing of many users on few connections
Connection pool management
Tracing and logging
