Creating a Domain with Managed Servers and Clusters

 


Configure the Administration Server

In every domain, one server must be designated the Administration server: the central point from which the whole domain is managed. The Configure the Administration Server window prompts you to define configuration information for the Administration Server. This information is used to access the Administration Server in the domain.

Servers can be reached using the following URL: protocol://listen-address:listen-port

In this URL, protocol can be any of the following:

listen-address and listen-port are defined in the Configure the Administration Server window.

To configure the Administration Server:

Review the values displayed in the window and modify them as necessary, using the guidelines provided in the following table. When you finish updating your settings, click Next.

In this field . . .

Do the following . . .

Note: Fields marked with an asterisk are required.

Name*

Enter a valid server name: a string of characters that can include spaces.

Each server instance in your product environment must have a unique name, regardless of the domain or cluster in which it resides, or whether it is an Administration Server or a Managed Server. In addition, the name of the Administration Server must be unique among all component names within the domain.

Note: This value is specified for identification purposes only; it is not used as part of the URL for applications that are deployed on the server. The server name is displayed in the WebLogic Server Administration Console. In addition, if you use WebLogic Server command-line utilities or APIs, you must specify this name to identify the server.

Listen address

From the drop-down list, select a value for the listen address. Valid values for the listen address are as follows:

  • All Local Addresses (default)

  • IP address of the computer that hosts the server

  • DNS name that resolves to the host

  • localhost (valid only for requests that are issued from the computer on which the server is running)

If you identify the listen address for a server instance as localhost, non-local processes cannot connect to the server instance. Only processes on the machine that hosts the server instance can connect to the server instance. If the server instance must be accessible as localhost (for example, if you create administrative scripts that connect to localhost), and it must also be accessible by remote processes, select All Local Addresses. The server instance determines the address of the machine and listens on it.

To learn more about Listen Addresses, see Specifying Listen Addresses.

Listen port

Enter a valid value for the listen port to be used for regular, non-secure requests (via protocols such as HTTP and T3). The default value is 7001. If you leave this field blank, the default value is used.

The valid listen port range is from 1 to 65534.

For more information, see Specifying Listen Ports.

SSL listen port

Enter a valid value to be used for secure requests (via protocols such as HTTPS and T3S). The default value is 7002. If you leave this field blank, the default value is used.

The valid listen port range is from 1 to 65534.

Note: By default, a server instance uses demonstration certificates to authenticate requests from a secure port. In a production environment, you must configure SSL to use certificates from a certificate authority. For more information, see "Configuring SSL" in Securing WebLogic Server at http://download.oracle.com/docs/cd/E13222_01/wls/docs91/secmanage/ssl.html.

For more information, see Specifying Listen Ports.

SSL enabled

Select the check box in this field to enable the SSL listen port. By default, the SSL is disabled for all new servers.


 

Specifying Listen Addresses

If you want to limit the valid listen address for a server, use the guidelines for specifying listen addresses provided in the following table.

If the listen address is set to . . .

Then the following is true . . .

All Local Addresses or DNS name

On multi-homed Windows machines, a server instance binds to all available IP addresses.

IP Address or DNS name

  • To connect to the server instance, processes can specify either the IP address or the corresponding DNS name.

  • Processes that specify localhost fail to connect.

  • You must update existing processes that use localhost to connect to the server instance.

  • For connections that specify the IP address for the listen address and a secured port for the listen port, host name verification must be disabled.

Note: To resolve a DNS name to an IP address, WebLogic Server must be able to contact an appropriate DNS server or obtain the IP address mapping locally. Therefore, if you specify a DNS name for the listen address, you must either leave a port open long enough for the WebLogic Server instance to connect to a DNS server and cache its mapping or you must specify the IP address mapping in a local file. If you specify an IP address for the listen address and then a client request specifies a DNS name, WebLogic Server will attempt to resolve the DNS name, but if it cannot access DNS name mapping, the request will fail.

localhost

  • Processes must specify localhost to connect to the server instance.

  • Only processes that reside on the machine that hosts the server instance (local processes) will be able to connect to the server instance.


 

Specifying Listen Ports

Refer to the following guidelines when specifying listen ports and secure listen ports:

 


Configure Managed Servers

The Configure Managed Servers window prompts you to provide the configuration information for one or more Managed Servers. Production environments typically deploy one or more Managed Servers, in addition to the Administration Server, to host enterprise applications. (For details, see Introduction to Domains.) This step is optional.

Note: You can create Managed Servers on remote machines using the pack and unpack commands. For more information, see "Creating and Starting a Managed Server on a Remote Machine: Main Steps" in Creating Templates and Domains Using the pack and unpack Commands at http://download.oracle.com/docs/cd/E13179_01/common/docs91/pack/tasks.html#remote.

To Configure Managed Servers:

  1. Review the current list of Managed Server configurations. Default values may vary, based on the domain source you selected earlier.
  2. Note: The wizard provides two views: a concise tabular view of all the Managed Servers and an individual view of each Managed Server, where each server is represented by a tab—you switch between servers by selecting the corresponding tab. To toggle the display mode between table and tab formats, click Switch Display.

  3. Add or modify entries as required by your domain, using the guidelines provided in the following table. To delete a Managed Server, select the Managed Server in the list and click Delete. When you finish updating your settings, click Next.
  4. In this field . . .

    Do the following . . .

    Note: Fields marked with an asterisk are required.

    Name*

    Enter a valid server name: a string of characters that can include spaces.

    Each server instance in your WebLogic environment must have a unique name, regardless of its function (Managed Server or Administration Server) and the domain or cluster in which it resides. In addition, the name of each Managed Server must be unique among all component names within the domain.

    The default value in this field is new_Server_n, where n specifies a numeric value used to differentiate among default Managed Server names; the value of n for the first Managed Server is 1. The value is incremented by 1 for each Managed Server that is added.

    Note: The server name is included for identification purposes only; it is not used as part of the URL for applications that are deployed on the server. The server name is displayed in the WebLogic Server Administration Console. In addition, if you use WebLogic Server command-line utilities or APIs, you must specify this name to identify the managed server.

    Listen address

    Select a value for the listen address from the drop-down list. Valid values for the listen-address are as follows:

    • All Local Addresses (default)

    • IP address of the computer that hosts the server

    • DNS name that resolves to the host

    • localhost (valid only for requests that are issued from the computer on which the server is running)

    If you identify a server instance's listen address as localhost, non-local processes cannot connect to the server instance. Only processes on the machine that hosts the server instance can connect to the server instance. If the server instance must be accessible as localhost (for example, if you create administrative scripts that connect to localhost), and it must also be accessible by remote processes, select All Local Addresses. The server instance determines the address of the machine and listens on it.

    If you intend to run the Managed Server on a remote machine, be sure to specify a valid IP address for the machine that will host the Managed Server.

    To learn more about listen addresses, see Specifying Listen Addresses.

    Listen port

    Enter a valid value for the listen port to be used for regular, non-secure requests (via protocols such as HTTP and T3). The default value is 7001. If you leave this field blank, the default value is used.

    The valid listen port range is from 1 to 65534.

    If you intend to run the Managed Server on a remote machine, be sure to specify a valid listen port for the machine that will host the Managed Server.

    For more information, see Specifying Listen Ports.

    SSL listen port

    Enter a valid value to be used for secure requests (via protocols such as HTTPS and T3S). The default value is 7002. If you leave this field blank, the default value is used.

    The valid listen port range is from 1 to 65534.

    Note: By default, a server instance uses demonstration certificates to authenticate requests from a secure port. In a production environment, you must configure SSL to use certificates from a certificate authority. For more information, see "Configuring SSL" in Securing WebLogic Server at http://download.oracle.com/docs/cd/E13222_01/wls/docs91/secmanage/ssl.html.

    For more information, see Specifying Listen Ports.

    SSL enabled

    Select the check box to enable the SSL Listen Port. The default is disabled.


     

 


Configure Clusters

A cluster is a group of WebLogic Server instances that work together to provide scalability and high-availability for applications. This window is displayed only if your domain contains at least one Managed Server.

The Configure Clusters window prompts you to configure the clusters in your domain. This step is optional.

To configure clusters:

  1. Review the current list of cluster configurations. Default values may vary, based on the domain source you selected earlier.
  2. Note: The wizard provides two views: a concise tabular view of all the clusters and an individual view of each cluster, where each cluster is represented by a tab—you switch between clusters by selecting the corresponding tab. To toggle the display mode between table and tab formats, click Switch Display.

  3. Add or modify entries, as required by your domain, using the guidelines provided in the following table. To delete a cluster, select the cluster in the list and click Delete. When you finish updating your settings, click Next.
  4. Note: If you are creating a domain that includes Service Bus functionality, you can configure only one cluster per domain.

    In this field . . .

    Enter a  . . .

    Note: Fields marked with an asterisk are required.

    Name*

    Valid cluster name: a string of characters that can include spaces.

    The name of the cluster must be unique among all component names within the domain.

    The default value in this field is new_Cluster_n, where n specifies a numeric value that is used to differentiate among all default cluster names; the value of n for the first cluster is 1. The value is incremented by 1 for each cluster that is added.

    Multicast address

    Multicast address for the cluster. This address is used by cluster members to communicate with each other. The default value is 239.192.0.0.

    Valid multicast addresses are any valid IP addresses from 224.0.0.1 to 239.255.255.255.

    Multicast port

    Multicast port for the cluster. The multicast port is used by cluster members to communicate with each other. The default value is 7001.

    Valid values for multicast ports are from 1 to 65534.

    Cluster address

    Cluster address that identifies the Managed Servers in the cluster.

    A cluster address can be one of the following:

    • Comma-separated list of IP addresses or DNS names and ports, for example: dns_name:port, dns_name:port

    • DNS name that maps to multiple IP addresses

    • localhost, DNS name, or IP address if the listen address of all Managed Servers is listening to the same address with unique port numbers

    The cluster address is used in entity and stateless EJBs to construct the host name portion of URLs. If the cluster address is not set, EJB handles may not work properly.
