<p>The Change Group Attributes (CHGGRPA) command changes the group attributes of an interactive job. The CHGGRPA command must be used to change an interactive job into a group job before a Transfer to Group Job (TFRGRPJOB) command can be used. The following attributes can be changed:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li>An interactive job can be changed into a group job.
|
||
|
|
</li>
|
||
|
|
<li>A group job can be changed into a non-group, interactive job.
|
||
|
|
</li>
|
||
|
|
<li>A message queue can be associated with a group.
|
||
|
|
</li>
|
||
|
|
<li>A message queue can be disassociated from a group.
|
||
|
|
</li>
|
||
|
|
<li>A group job's descriptive text can be changed.
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>More information about group jobs is in the Work Management information in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

<p><b>Example 1: Changing an Interactive Job to a Group Job</b>
|

|
|
</p>
|
||
|
|
<p>
|

|

<pre>
|

CHGGRPA GRPJOB(GROUPJ1) MSGQ(QGPL/GRPMSGQ)
|
||

|
</pre>
|
||
|
|
</p>
|
||
|
|
<p>An interactive job is first changed to a group job before it is allowed to create other group jobs at the work station. This command changes a work station job into a group job with the group job name GROUPJ1; a message queue is associated with the group and (as long as it is in break or notify mode in the job issuing a TFRGRPJOB or End Group Job (ENDGRPJOB) command) is allocated to the active job in the group. The group data area (*GDA) is also created.
|
||
|
|
</p>
|
||
|
|
<p><b>Example 2: Changing a Group Job to a Nongroup Job</b>
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
<pre>
|
||
|
|
CHGGRPA GRPJOB(*NONE)
|
||
|
|
</pre>
|
||
|
|
</p>
|
||
|
|
<p>Assume that the job in the previous example issues this command. Assume also that the job is the only active job in the group. Group job GROUPJ1 is changed into a nongroup, interactive job. The group job name is removed, and the group data area (*GDA) is deleted. The change from a group job into a nongroup job occurs only if it is the only active job in the group.
