7.4 Removing an Origin Server from a Pool

You can remove an origin server from a pool by using either the administration console or the CLI.

Note:

• When dynamic discovery is enabled (see Section 6.5), if you delete an origin server that is an Oracle WebLogic Server instance in a cluster, and then reconfigure the Oracle Traffic Director instance, the instance might not start if no valid origin servers remain in the pool.

• When you remove an origin server from a pool, you are, in effect, modifying a configuration. So for the updated configuration to take effect in the Oracle Traffic Director instances, you should redeploy the configuration as described in Section 4.3, "Deploying a Configuration."

• 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."

Removing an Origin Server from a Pool Using the Administration Console

To remove an origin server from a pool 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 delete origin servers.

4. In the navigation pane, expand Origin-Server Pools, expand the pool for which you want to delete origin servers, and select Origin Servers.

   A list of the origin servers in the selected pool is displayed.

5. Click the Delete icon for the origin server that you want to delete.

   A message is displayed in the Console Message pane confirming that the origin server was deleted.

   In addition, the Deployment Pending message is displayed at the top of the main pane. You can either deploy the updated configuration immediately by clicking Deploy Changes, or you can do so later after making further changes, as described in Section 4.3, "Deploying a Configuration."

Removing an Origin Server from a Pool Using the CLI

To remove an origin server from a pool, run the delete-origin-server command, as shown in the following example:

tadm> delete-origin-server --config=soa --origin-server-pool=osp1 soa-app2.example.com:1900
OTD-70201 Command 'delete-origin-server' ran successfully.

For the updated configuration to take effect, you should deploy it to the Oracle Traffic Director instances by using the deploy-config command.

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