<p>The Open List of Activation Group Attributes (QWVOLAGP) API generates a list
of all the activation groups that are associated with a given job and their
attributes. The QWVOLAGP API places the list into a receiver variable. You can
access additional records by using the Get List Entries (QGYGTLE) API. On
successful completion of the QWVOLAGP API, a handle is returned in the list
information parameter. You may use this handle on subsequent calls to the
following APIs:</p>
<dl>
<dd>Get List Entries (QGYGTLE)</dd>
<dd>Find Entry Number in List (QGYFNDE)</dd>
<dd>Close List (QGYCLST)</dd>
</dl>
<p>The records returned by the QWVOLAGP API include an information status field
that describes the completeness and validity of the information. Be sure to
check the information status field before using any other information
returned.</p>
<br>
<h3>Authorities and Locks</h3>
<dl>
<dt><em>Job Authority</em></dt>
<dd>
<ul>
<li>*JOBCTL if the job for which activation group attributes are being
retrieved has a user profile different from that of the job that calls the
QWVOLAGP API.</li>
</ul>
For additional information on these authorities, see the <a href=
"../books/sc415302.pdf" target="_blank">iSeries Security Reference</a> <img
src="wbpdf.gif" alt="Link to PDF"> book.</dd>
</dl>
<br>
<h3>Required Parameter Group</h3>
<dl>
<dt><strong>Receiver variable</strong></dt>
<dd>OUTPUT; CHAR(*)
<p>The variable that is used to return the activation group attributes that was
requested.</p>
</dd>
<dt><strong>Length of receiver variable</strong></dt>
<dd>INPUT; BINARY(4)
<p>The length of the receiver variable.</p>
</dd>
<dt><strong>List information</strong></dt>
<dd>OUTPUT; CHAR(80)
<p>Information about the list of activation group attributes that were opened.
For a description of the layout of this parameter, see <a href="../apiref/oli.htm">Format
of Open List Information</a>.</p>
</dd>
<dt><strong>Number of records to return</strong></dt>
<dd>INPUT; BINARY(4)
<p>The number of records in the list to put into the receiver variable.</p>
</dd>
<dt><strong>Format name</strong></dt>
<dd>INPUT; CHAR(8)
<p>The format of the information to be returned in the receiver variable. You
must use the following format name:</p>
<table cellpadding="5">
<!-- cols="15 85" -->
<tr>
<td align="left" valign="top"><em>RAGA0100</em></td>
<td align="left" valign="top">This format is described in <a href=
"#HDRRAGA100">RAGA0100 Format</a>.</td>
</tr>
</table>
<br>
</dd>
<dt><strong>Qualified job name</strong></dt>
<dd>INPUT; CHAR(26)
<p>The job name, the job user profile, and the job number of the job for which
you want to return activation group attributes.</p>
<table cellpadding="5">
<!-- cols="15 85" -->
<tr>
<td align="left" valign="top"><em>CHAR 1-10</em></td>
<td align="left" valign="top">The job name</td>
</tr>
<tr>
<td align="left" valign="top"><em>CHAR 11-20</em></td>
<td align="left" valign="top">The user profile</td>
</tr>
<tr>
<td align="left" valign="top"><em>CHAR 21-26</em></td>
<td align="left" valign="top">The job number</td>
</tr>
</table>
<p>You can use these special values for the qualified job name:</p>
<table cellpadding="5">
<!-- cols="10 90" -->
<tr>
<td align="left" valign="top"><em>*</em></td>
<td align="left" valign="top">The job in which this program is running. The
rest of the qualified job name parameter must be blank.</td>
</tr>
<tr>
<td align="left" valign="top"><em>*INT</em></td>
<td align="left" valign="top">The internal job identifier locates the job. The
rest of the qualified job name parameter must be blank.</td>
</tr>
</table>
<br>
</dd>
<dt><strong>Internal job identifier</strong></dt>
<dd>INPUT; CHAR(16)
<p>The internal name for the job. The List Job (QUSLJOB) API creates this
identifier. If you do not specify *INT for the qualified job name parameter,
this parameter must contain blanks.</p>
<p>If your application already has this information available from the List Job
(QUSLJOB) API, the QWVOLAGP API can locate the job more quickly with this
information than with a job name. However, if you call QUSLJOB solely to obtain
this parameter for use by QWVOLAGP, you would get poorer performance than by
using a job name in calling QWVOLAGP.</p>
</dd>
<dt><strong>Error code</strong></dt>
<dd>I/O; CHAR(*)
<p>The structure in which to return error information. For the format of the
structure, see <a href="../apiref/error.htm#hdrerrcod">Error Code Parameter</a>.</p>
</dd>
</dl>

<p><strong>Activation group number.</strong> The activation group number of the
activation group listed. This is the last 32 bits of a 64 bit internal number
that uniquely identifies the activation group within the job. The full 64 bit
value can be retrieved using the "Activation group number long" field.</p>
<p><strong>Activation group number long.</strong> The 64 bit activation
group number of the activation group listed. This is an internal number that
uniquely identifies the activation group within the job.</p>
<p><strong>Activation group state.</strong> The state of the activation group.
Possible values follow:</p>
<table cellpadding="5">

</table>
<p><strong>Heap storage size.</strong> The total amount of heap storage that is
allocated to the activation group in bytes.</p>

<p><strong>Note:</strong> It is not recommended to reclaim eligible activation
groups if you are not familiar with that activation group. Other activation
groups may have references to the activation group that you are reclaiming. For
example, a program of one activation group could be bound to a service program
that belongs to another activation group. If you reclaim the service program's
activation group and then call the program, you will get a destroyed object
error when the service program is referred to.</p>
<p><strong>Number of activations.</strong> The total number of program
activations in this activation group.</p>

group is shared or not. A shared activation group is an activation group that
belongs to more than one job at the same time. Possible values follow:</p>
<table cellpadding="5">
