Managing the TCP/IP server
The DRDA® and DDM TCP/IP server does not typically require any changes to your existing system configuration. At some time, you might want to change the way the system manages the server jobs to better meet your needs, to solve a problem, to improve the system performance, or to look at the jobs on the system.
To make such changes and meet your processing requirements, know which objects affect which pieces of the system and how to change those objects. This topic collection describes how to manage the DRDA and DDM server jobs that communicate by using sockets over TCP. It describes the subsystem in which the system runs, the objects that affect the system, and how to manage those resources.
To fully understand how to manage your System i™ product, it is suggested that you carefully review the Work management topic collection before you continue with this topic collection. This topic collection describes, at a high level, some of the work management concepts that understand to work with the server jobs, and how the concepts and objects relate to the system. This topic collection then shows you how the TCP/IP server can be managed and how they fit in with the rest of the system.
- DRDA TCP/IP server terminology
The same software is used for both DDM and DRDA TCP/IP access to DB2 Universal Database™ for iSeries™.
- TCP/IP communication support concepts for DDM
There are several concepts that pertain specifically to the TCP/IP communications support used by DRDA and DDM.
- DRDA and DDM server jobs
These topics discuss DRDA and DDM server jobs.
- Configuring the DDM server job subsystem
By default, the DDM TCP/IP server jobs run in the QUSRWRK subsystem. Using iSeries Navigator, you can configure DDM server jobs to run all or certain server jobs in alternate subsystems based on the client's IP address.
- Identifying server jobs
Being able to identify a particular job is a prerequisite to investigating problems and gathering performance data.
