<h1 class="topictitle1">Internal identifiers</h1>
|
|
<div><p>You know of jobs, spooled files, and so forth, by their names.
|
|
The system uses an ID that is associated with the name. The ID is assigned
|
|
based on usage.</p>
|
|
<p>Several of the APIs either require or allow you to use an internal ID.
|
|
When you use an internal ID, it is generally faster because the system does
|
|
not have to convert the external name to the internal ID.</p>
|
|
<p>A variety of terminology is used to identify internal IDs. For example:</p>
|
|
<ul><li>Work Management uses an <em>internal job identifier</em>.</li>
|
|
<li>Spooling uses an <em>internal spooled file identifier</em>.</li>
|
|
<li>Security uses the term <em>handle</em> to mean the user profile that is
|
|
currently running the job.</li>
|
|
<li>Message handling uses the term <em>message key</em> (also appears on CL
|
|
commands) to identify a message in a message queue.</li>
|
|
</ul>
|
|
<p>The internal values are often accessed in one API and then used in another.
|
|
For example, if you want a list of jobs, you would use the List Jobs (QUSLJOB)
|
|
API, which provides the internal job ID for each job in the list. You could
|
|
then use the internal job ID to access a spooled file for a job with the Retrieve
|
|
Spooled File Attributes (QUSRSPLA) API.</p>
