<p>The Change Network Attributes (CHGNETA) command changes the network attributes of a system. A network attribute is control information about the communications environment. Network attributes contain specifications that can be used for networking and communications.
</p>
<p><b>Restrictions:</b>
</p>
<ol>
<li>This command is shipped with public exclude (*EXCLUDE) authority. When this command is shipped, authority is issued only to the security officer. The security officer can grant the use of this command to other users.
</li>
<li>A user is required to have both all object (*ALLOBJ) and input/output system configuration (*IOSYSCFG) special authority to change the network attributes <b>Network job action (JOBACN)</b>, <b>DDM/DRDA request access (DDMACC)</b>, and <b>Client request access (PCSACC)</b>.
</li>
<li>A user is required to have *IOSYSCFG special authority to change the network attribute <b>Allow add to cluster (ALWADDCLU)</b>.
</li>
</ol>
<p><b>Notes:</b>
</p>
<ol>
<li>Information about specifying communications names is in the CL concepts and reference topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.
</li>
<li>Information about advanced program-to-program communications (APPC), advanced peer-to-peer networking (APPN), and high-performance routing (HPR) is in the APPN Support information in the iSeries Information Center at http://www.iseries.ibm.com/infocenter.
</li>
<li>More information on this command is in the Work Management information in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter or the Communcations Management book, SC41-5406.

<div><h3><a name="CHGNETA.COMMAND.EXAMPLES">Examples</a> </h3>
<p><b>Example 1: Changing the Pending System Name</b>
</p>
<p>
<pre>
CHGNETA SYSNAME(SYSTEST) ALRSTS(*ON)
ALRPRIFP(*YES) ALRLOGSTS(*LOCAL)
</pre>
</p>
<p>This command changes the pending system name. The current system name is changed at the next IPL. Local alerts are generated and logged and the system is a primary focal point.
</p>
<p><b>Example 2: Changing the Node Servers</b>
</p>
<p>
<pre>
CHGNETA LCLCPNAME(CPNAME) LCLNETID(NETNAME)
NETSERVER((*LCLNETID BOSTON)
(MINN ROCHEST) (MAINE BANGOR))
</pre>
</p>
<p>This command changes the name of the local control point, the network ID, and the list of network node servers. The servers are used only if the node type is *ENDNODE or *BEXNODE.
</p>
<p><b>Example 3: Clearing the List of Node Servers</b>
</p>
<p>
<pre>
CHGNETA NETSERVER(*NONE) DDMACC(DDMLIB/DDMPGM)
</pre>
</p>
<p>This command clears the list of network node servers and sets the name of the DDM access program.
</p>
<p><b>Example 4: Implementing the APPN Virtual Object Model</b>
</p>
<p>
<pre>
CHGNETA ALWVRTAPPN(*YES)
</pre>
</p>
<p>This command causes any future APPN devices and sessions to use virtual controllers.
</p>
<p><b>Example 5: Allowing HPR Transport Tower for APPN Sessions</b>
</p>
<p>
<pre>
CHGNETA ALWHPRTWR(*YES) HPRPTHTMR(1 2 4 8)
</pre>
</p>
<p>This command enables APPN session traffic to use HPR transport tower support when possible. It also resets the HPR path switch timers to the default values.
