# Set EJB target servers and clusters

When you deploy an EJB, you specify the servers and clusters to which the EJB deployment is targeted. After you have deployed an EJB, you can update the servers and clusters to which it is targeted.

To set target servers and clusters for a deployed EJB:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
2. In the left pane of the Administration Console, select Deployments.

   The right pane lists the EJBs and other modules that you have deployed, or tried to deploy.

3. In the right pane, click the desired EJB.
4. Select the Targets tab.

   Servers and clusters in the domain are displayed.

5. Select the check box next to the individual servers and/or clusters to which you wish to deploy the EJB and click Save.

   By default, the Administration Console deploys an EJB to all server instances in the cluster (the "All servers in the cluster" option). To deploy the EJB to selected servers in a cluster, select "Part of the cluster", and then select the individual server instances to which you want to deploy the EJB.

6. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
   Not all changes take effect immediately—some require a restart (see Use the Change Center).
