Managing servers

After you have added an application, added a component, and added an environment, you must add a server, or multiple servers, and associate them with environments. Environments are platforms on which applications are deployed and configured. A software environment is a collection of hosted servers and application software that provides a platform for running and testing applications.Your application resides on the server or servers that you define. You can group servers into server groups.You can also divide servers into server levels. Server levels are used to group servers according to functional use, such as JBoss servers or Load Balancers. You can further create server level groups.The following image depicts the infrastructure model that has server groups, server levels and server level groups:

Use the following procedures to manage servers:

• • • To create a new server
    • To create a server level

To create a new server

1. Click Environment > Servers.
2. On the Active Servers page, click Create Server on the right.

3. Enter the following information for the server:

   Field	Description
   Name	A unique name for the server
   Dns/url	The Domain Name System (DNS) or Uniform Resource Locator (URL) for accessing the server
   IP address	The Internet Protocol (IP) address of the server
   OS platform	The operating system on which the server runs

4. In the Server Groups field, select the server groups that you want to associate with the server. 
5. In the Environments field, select the environments that you want to associate with the server.
6. Click Create.

To create a server level

After you have created servers and associated them with environments, you can group servers virtually within server levelsaccording to functional use. For example, you can create a server level to group together all JBoss servers or to group together your load balancers.During the creation of a server level, you first create the server level itself and then you create server instances for the server level. An instance of a server level is an occurrence within the space of a server, such as Application Server 1 or Application Server 2.

1. Click Environment > Servers and then click Create Server Level on the right.
2. In the dialog box, enter server level name in the Name field.
3. (Optional) Add a description in the Description field. 
4. Click Create Level.
5. On the Server instance page, enter a name and (optionally) a description for the instance.
6. From the Parent field, select a parent server for the instance.
7. Select the relevant environments in the Environment field.
8. Select the relevant properties in the Properties field.
9. Click Create your server instance name.
