<h1 class="topictitle1">Object identification</h1>
|
|
<div><p>Because the existence of an independent disk pool on a server means that
|
|
multiple databases exist on a single server, identifying an object is more
|
|
complex than it is on a system with only a single system database. When multiple
|
|
databases exist, it is possible to duplicate the names of libraries and objects
|
|
in separate databases. The library name and object name do not necessarily
|
|
uniquely identify an object. There will be times when you also need to know
|
|
the name of the independent disk pool. The name of the independent disk pool
|
|
and its database are, by default, the same. However, they do not necessarily
|
|
have to match. A database name can be up to 18 characters long, while an
|
|
independent disk pool name can be up to 10 characters long.</p>
|
|
<p>While the same library name can exist in two different disk pool groups,
|
|
libraries cannot have the same name in the system disk pool as in an independent
|
|
disk pool. </p>
|
|
<div class="section"><h4 class="sectiontitle">Control language (CL) commands</h4>When using control language
|
|
(CL) commands that support specification of *ALL or *ALLUSR for the libraries
|
|
to be searched, the system will typically interpret this to mean "all (user)
|
|
libraries in your current library namespace" rather than "all (user) libraries
|
|
on the system." Some commands may interpret *ALL or *ALLUSR differently,
|
|
so it is important to check the command documentation. <p>If you
|
|
used the Display Object Description (<a href="../cl/dspobjd.htm">DSPOBJD</a>)
|
|
command, certain system libraries, like QSYS, may appear multiple times if
|
|
the command is showing information for both the system disk pool and one or
|
|
more independent disk pools. </p>
|
|
<div class="note"><span class="notetitle">Note:</span> Most messages that go to the job log
|
|
(QSYSOPR) or history log do not contain the name of the independent disk
|
|
pool. They only contain the object name and library. You must determine what,
|
|
if any, disk pool group the job that issued the message was using to be able
|
|
to find the object.</div>
