<h3><a name="acsjvmcust"></a>Set JVM custom properties</h3>
|
||
|
|
|
||
|
|
<p>You can set JVM custom properties for application servers, deployment managers, and node agents.</p>
|
||
|
|
|
||
|
|
<p><strong>Note:</strong> If you are using Network Deployment, you must set custom properties for the application server and the deployment manager. If you do not set them in the deployment manager, the plugin configuration regeneration cannot set the correct values in the plugin configuration file.</p>
|
||
|
|
|
||
|
|
<p>To set JVM custom properties, perform these steps:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li><a href="acstart.htm">Start the administrative console</a>.</li>
|
||
|
|
<li>Navigate to the application server, deployment manager, or node agent.
|
||
|
|
<ul>
|
||
|
|
<li>For an application server, expand <strong>Servers</strong>, click <strong>Application Servers</strong> and click the name of your application server.</li>
|
||
|
|
<li>For a deployment manager, expand <strong>System Administration</strong> and click <strong>Deployment Manager</strong>.</li>
|
||
|
|
<li>For a node agent, expand <strong>System Administration</strong>, click <strong>Node Agents</strong>, and click the name of the node agent.</li>
|
||
|
|
</ul></li>
|
||
|
|
<li>Click <strong>Process Definition</strong>.</li>
|
||
|
|
<li>On the <strong>Process Definition</strong> page, click <strong>Java Virtual Machine</strong>.</li>
|
||
|
|
<li>On the <strong>Java Virtual Machine</strong> page, click <strong>Custom Properties</strong>.</li>
|
||
|
|
<li>On the <strong>Custom Properties</strong> page, you can create a new custom property or change the value of an existing custom property.
|
||
|
|
<ul>
|
||
|
|
<li>To create a new custom property, perform these steps:
|
||
|
|
<ol type="a">
|
||
|
|
<li>Click <strong>New</strong>.</li>
|
||
|
|
<li>In the <strong>Name</strong> field, specify the name of the custom property. In the <strong>Value</strong> field, specify an appropriate value for the property.</li>
|
||
|
|
<li>Click <strong>Apply</strong> or <strong>OK</strong>.</li>
|
||
|
|
</ol></li>
|
||
|
|
<li>To change the value of an existing custom property, perform these steps:
|
||
|
|
<ol type="a">
|
||
|
|
<li>Click the name of the custom property that you want to change.</li>
|
||
|
|
<li>Specify a new value for the property.</li>
|
||
|
|
<li>Click <strong>Apply</strong> or <strong>OK</strong>.</li>
|
||
|
|
</ol></li>
|
||
|
|
</ul></li>
|
||
|
|
<li><a href="acsave.htm">Save the configuration</a>.</li>
|
||
|
|
<li>Restart the application server for the changes to take effect.</li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<p><strong>Example: the com.ibm.websphere.network.useMultiHome custom property</strong></p>
|
||
|
|
|
||
|
|
<p>You can set this JVM custom property in a multihomed environment where WebSphere Application Server is restricted to listen only on a specific IP address for Discovery and SOAP messages. By default, the value of the property is <tt>true</tt> and the application server listens on all IP addresses on the host for Discovery and SOAP messages. If the property is set to <tt>false</tt>, then WebSphere Application Server will only listen on the configured host name for Discovery and SOAP messages. If you set the property to <tt>false</tt>, you must have a host name configured on WebSphere Application Server that resolves to a specific IP address.</p>
|
||
|
|
|
||
|
|
<p>To set this property so that the application server listens on only one port, follow these steps:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>In the administrative console, navigate to <strong>Servers --> Application Servers --> Process Definition --> Java Virtual Machine --> Custom Properties</strong>.</li>
|
||
|
|
<li>Click <strong>New</strong>.</li>
|
||
|
|
<li>In the <strong>Name</strong> field, specify <tt>com.ibm.websphere.network.useMultiHome</tt>.</li>
|
||
|
|
<li>In the <strong>Value</strong> field, specify <tt>false</tt>.</li>
|
||
|
|
<li>Click <strong>OK</strong>.</li>
|
||
|
|
<li>Save the configuration.</li>
|
||
|
|
</ol>
