<h1 class="topictitle1">Routing entries</h1>
|
|
<div><p>The routing entry identifies the main storage subsystem pool to
|
|
use, the controlling program to run (typically the system-supplied program
|
|
QCMD), and additional run-time information (stored in the class object). Routing
|
|
entries are stored in the subsystem description.</p>
|
|
<p>A routing entry can be likened to a single entry in a shopping mall directory.
|
|
Customers that cannot find the store they need may use a directory to help
|
|
send them in the right direction. The same is true on the iSeries™ system.
|
|
Routing entries guide the job to the correct place. Routing entries in a subsystem
|
|
description specify the program to be called to control a routing step for
|
|
a job running in the subsystem, which memory pool the job will use, and from
|
|
which class to get the run-time attributes. Routing data identifies a routing
|
|
entry for the job to use. Together, routing entries and routing data provide
|
|
information about starting a job in a subsystem. </p>
|
|
<p>Routing entries consist of these parts; the subsystem description,
|
|
class, comparison data, maximum active routing steps, memory pool ID, program
|
|
to call, thread resources affinity, resources affinity group, and the sequence
|
|
number. </p>
|
|
</div>

<div>

|
<ul class="ullinks">
|
|
<li class="ulchildlink"><strong><a href="rzaksrtentryclass.htm">Class</a></strong><br />
|
|
Job run-time attributes are contained in the class object that
|
|
is specified in the (<span class="parmname">CLS</span>) parameter in the routing entry.
|
|
If a job consists of multiple routing steps, the class used by each subsequent
|
|
routing step is specified in the routing entry used to start the routing step.
|
|
If the class does not exist when the routing entry is added, a library qualifier
|
|
must be specified because the qualified class name is kept in the subsystem
|
|
description.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaksroutentrycompare.htm">Comparison data</a></strong><br />
|
|
The comparison value (<span class="parmname">CMPVAL</span>) parameter of
|
|
the routing entry specifies data that is compared with routing data to determine
|
|
which routing entry to use. (The routing entry also specifies the starting
|
|
position for the comparison.) The routing data is compared with the comparison
|
|
value of each routing entry in sequence number order until a match is found.
|
|
The sequence number contained in a routing entry defines the order in which
|
|
the routing entries are scanned and can be used as the identifier of the routing
|
|
entry. </li>
|
|
<li class="ulchildlink"><strong><a href="rzaksrtentrymaxact.htm">Maximum active routing steps</a></strong><br />
|
|
The maximum active routing steps <span class="parmname">(MAXACT) </span>parameter
|
|
of the routing entry specifies the maximum number of routing steps (jobs)
|
|
that can be active at the same time through this routing entry. </li>
|
|
<li class="ulchildlink"><strong><a href="rzaksrtentrymempool.htm">Memory pool ID</a></strong><br />
|
|
The memory pool ID (<span class="parmname">POOLID</span>) parameter of the
|
|
routing entry specifies the pool identifier of the storage pool in which the
|
|
program runs. The pool identifier specified here relates to the storage pools
|
|
in the subsystem description. </li>
