<p>The Retrieve Server Job Information (QGYRTVSJ) API returns information about
|
|
auxiliary server jobs started for the current job on the iSeries server. This
|
|
API will return the number of auxiliary server jobs and the job names for each
|
|
auxiliary server job. This information can be used to:</p>
|
|
|
|
<ul>
|
|
<li>Retrieve information about the auxiliary server jobs by calling the
|
|
Retrieve Job Information (QUSRJOBI) API.</li>
|
|
|
|
<li>Change the run-time attributes of one or more auxiliary server jobs using
|
|
the Change Job (CHGJOB) CL command.</li>
|
|
</ul>
|
|
|
|
<p>An <strong>auxiliary server job</strong> is used to do work asynchronously
|
|
from the job that started the auxiliary server job. For example, the auxiliary
|
|
server job is used to complete building lists of information.</p>
|
|
|
|
<p>The Change Server Job (QGYCHGSJ) API can be used to change the maximum
|
|
number of auxiliary server jobs that can be active at any one time.</p>
|
|

<p>The receiver variable that receives the information requested. You can
|

specify the size of the area to be smaller than the format requested as long as
|

you specify the length parameter correctly. As a result, the API returns only

the data that the area can hold.</p>

<dt><strong>Length of receiver variable</strong></dt>

<p>The length of the receiver variable provided. The length of receiver

variable parameter may be specified up to the size of the receiver variable
|
|
specified in the user program. If the length of receiver variable parameter
|
|
specified is larger than the allocated size of the receiver variable specified
|

in the user program, the results are not predictable. The minimum length is 8

bytes.</p>
