These topics describe how to manage the DRDA® and DDM server jobs that communicate using sockets over TCP. It describes the subsystem in which the server runs, the objects that affect the server, and how to manage those resources.
The DRDA and DDM TCP/IP server that is shipped with the i5/OS™ program does not typically require any changes to your existing system configuration in order to work correctly. It is set up and configured when you install i5/OS. At some time, you might want to change the way the system manages the server jobs to better meet your needs, solve a problem, improve the system's performance, or look at the jobs on the system. To make such changes and meet your processing requirements, you need to know which objects affect which pieces of the system and how to change those objects.
These topics describe, at a high level, some of the work management concepts that need to be understood in order to work with the server jobs and how the concepts and objects relate to the server.
