<h1 class="topictitle1">Work management on the <span class="keyword">iSeries server</span></h1>
|
|
<div><p>All of the work done on the <span class="keyword">iSeries™ server</span> is
|
|
submitted through the work management function. On an <span class="keyword">iSeries server</span>,
|
|
you can design specialized operating environments to handle different types
|
|
of work to satisfy the requirements of your server.</p>
|
|
<p>However, when the operating system is installed, it includes a work management
|
|
environment that supports interactive and batch processing, communications,
|
|
and spool processing.</p>
|
|
<p>On the server, all user jobs operate in an environment called a <dfn class="term">subsystem</dfn>,
|
|
defined by a subsystem description, where the server coordinates processing
|
|
and resources. Users can control a group of jobs with common characteristics
|
|
independently of other jobs if the jobs are placed in the same subsystem.
|
|
You can easily start and end subsystems as needed to support the work being
|
|
done and to maintain the performance characteristics you want.</p>
|
|
<p>The basic types of jobs that run on the server are interactive, communications,
|
|
batch, spooled, autostart, and prestart.</p>
|
|
<p>An interactive job starts when you sign on a workstation and ends when
|
|
you sign off. An Advanced Program-to-Program Communication (APPC) batch
|
|
job is a job started from a program start request from another system. A non-communications
|
|
batch job is started from a job queue. Job queues are not used when starting
|
|
a communications batch job. Spooling functions are available for both input
|
|
and output. Autostart jobs perform repetitive work or one-time initialization
|
|
work. Autostart jobs are associated with a particular subsystem, and each
|
|
time the subsystem is started, the autostart jobs associated with it are started.
|
|
Prestart jobs are jobs that start running before the remote program sends
|
|
a program start request.</p>

|
|
One subsystem, called a <dfn class="term">controlling subsystem</dfn>, starts
|
|
automatically when you load the server. Two controlling subsystem configurations
|
|
are supplied by IBM<sup>®</sup>.</li>

<li class="ulchildlink"><strong><a href="rbal1considappc.htm">APPC subsystems</a></strong><br />
|
|
In a distributed relational database using an Systems Network Architecture (SNA) network, communications jobs and interactive jobs are the main types of work an administrator must plan to manage on each server.</li>
|
|
<li class="ulchildlink"><strong><a href="rbal1tcpipsub.htm">TCP/IP subsystems</a></strong><br />
|
|
By default, the DDM TCP/IP server prestart jobs used for DRDA<sup>®</sup> TCP/IP connections
|
|
run in the QUSRWRK subsystem. QUSRWRK is the user work subsystem. It contains
|
|
jobs that are started by servers to do work on behalf of a user. The DRDA<sup>®</sup> listener
|
|
job that dispatches work to the prestart jobs runs in QSYSWRK. </li>
