5.4 Updating Oracle Traffic Director Instances Without Restarting

When you make changes to some configuration parameters, the running Oracle Traffic Director instances of the configuration need not be restarted for the changes in the configuration to take effect. You can dynamically reconfigure the Oracle Traffic Director instances to reflect the new configuration.

For a list of the parameters that support dynamic reconfiguration, see "Dynamic Reconfiguration" in the Oracle Traffic Director Configuration Files Reference.

You can dynamically reconfigure the running instances of a configuration by using either the administration console or the CLI.

Note:

The CLI examples in this section are shown in shell mode (tadm>). For information about invoking the CLI shell, see Section 2.3.1, "Accessing the Command-Line Interface."

Reconfiguring an Oracle Traffic Director Instance Using the Administration Console

To reconfigure an Oracle Traffic Director instance by using the administration console, do the following:

1. Log in to the administration console, as described in Section 2.3.2, "Accessing the Administration Console."

2. Click the Configurations button that is situated at the upper left corner of the page.

   A list of the available configurations is displayed.

3. Select the configuration for which you want to reconfigure instances.

4. In the navigation pane, select Instances.

5. Click the Reconfigure button for the instance that you want to update dynamically.

   A message is displayed in the Console Messages pane confirming that the instance was reconfigured.

Reconfiguring Oracle Traffic Director Instances Using the CLI

To reconfigure one or more Oracle Traffic Director instances of a configuration, run the reconfig-instance command.

For example, the following command reconfigures the instances of the configuration soa on the nodes apps1 and apps2.

tadm> reconfig-instance --config=soa apps1 apps2

For more information about reconfig-instance, see the Oracle Traffic Director Command-Line Reference or run the command with the --help option.

Note:

Alternatively, you can use the following command from within the instance directory:

> $INSTANCE_HOME/net-config_name/bin/reconfig
