B.5 Specify Domain Name and Location Screen

Specify the following information for the domain you are creating:

• Domain name

  The name of the domain you want to create. The default name is base_domain.

• Domain Location

  The absolute path to the directory where this domain should be created. The default location is MW_HOME/user_projects/domains (on UNIX operating systems) or MW_HOME\user_projects\domains (on Windows operating systems), but you can specify any location.

  Note:

  On Windows systems, be sure to include the drive letter when you specify the domain location.

• Application Location

  The absolute path to the directory where applications created in this domain should reside. The default location is MW_HOME/user_projects/applications (on UNIX operating systems) or MW_HOME\user_projects\applications (on Windows operating systems).

  Note:

  On Windows systems, be sure to include the drive letter when you specify the application location.

B.6 Configure Administrator Username and Password Screen

Create a user that will be assigned to the Administrator role. This user is the default administrator used to start development mode servers.

• User name

  Specify the user name. The default name is weblogic.

• User password

  Specify the password for the user.

• Confirm user password

  Re-enter the user password.

• Description

  Enter a description for the user. This field is optional.

B.7 Configure Server Start Mode and JDK Screen

In the WebLogic Domain Startup Mode section, select one of the following startup modes:

• Development Mode

  Development mode should be used while you are developing your applications. Development mode uses a relaxed security configuration and enables you to auto-deploy applications. In this mode, boot.properties is used for username and passwords and polling is used for application deployment.

• Production Mode

  Production mode shouldbe used when your application is running in its final form. A production domain uses full security and may use clusters or other advanced features. In this mode, usernames and passwords are required and polling is not used for application deployment.

In the JDK Selection section, select the recommended JDK for your startup mode from the list of available JDKs, or select Other JDK and click Browse to find another JDK on your system. The recommended JDKs are described in the text for each mode in the WebLogic Domain Startup Mode section.

B.8 Configure JDBC Component Schema Screen

Configure the schema owner and password for each component schema listed on this screen. Changes to any of the fields on this screen are applied to all selected component schema in the table.

For example, if all of your schemas reside on the same database, select all of the schemas in the table, then specify the appropriate database values for the schemas (DBMS/Service, Host Name, and Port).

If, for example, you hare a different password for each schema, then you must select each schema individually and specify the password for the selected schema only.

Review the table on this screen and identify which fields you need to modify:

• Vendor

  Select the vendor for your database from the drop-down list.

• Driver

  Select the driver type from the drop-down list.

• Schema Owner

B.10 Select Optional Configuration Screen

Select any category for which you want to perform custom or advanced configuration:

• Administration Server

  Select this to edit your Administration Server settings. You will be able to:

  • Change the name of your Administration Server (default is AdminServer).

  • Specify custom port numbers.

  • Configure the Administration Server to accept SSL connections.

• Managed Servers, Clusters and Machines

  Select this to add or delete managed servers, clusters, and machines. You can also modify the settings of any existing server, cluster, or machine.

• Deployments and Services

  Select this to customize how deployments and services are targeted to machines and clusters.

• JMS File Store

  Select this to customize your JMS file store settings.

• RDBMS Security Store

  Select this if you want to configure an external relational database management system (RDBMS) as a data store for various security providers.

B.11 Configure Administration Server Screen

The Administration Server is the primary tool used to manage a WebLogic Server domain.

One WebLogic Server instance in each domain is configured as the Administration Server. If you have multiple WebLogic Server instances, then all the other instances are referred to as Managed Servers. In a domain with only one WebLogic Server instance, that instance functions both as Administration Server and Managed Server.

• Name

  Specify the name of your Administration Server. The default name is AdminServer.

• Listen Address

  Use the drop-down list to select an address or range of addresses that the Administration Server will listen to for events. The default selection is All Local Addresses.

• Listen Port

  Specify the listen port number. The default port number is 7001.

Select SSL enabled if you want your Administration Server to accept SSL connections. Be sure to specify the SSL Listen Port if you select the SSL enabled option.

B.12 Configure Managed Servers Screen

A managed server is an instance of WebLogic Server used to host enterprise applications. A typical production environment has at least one managed server, which is managed by the Administration Server.

Use this screen to add or delete managed servers; click Add to add a managed server. To delete a managed server, select the server name and click Delete.

For each managed server, specify:

• Name

  Name of the managed server. Each server within the domain must have a unique name. The server name is not used as part of the URL for applications that are deployed on the server. It is for your identification purposes only.

• Listen Address

  Enter an IP address or DNS name if you want to limit the number of valid addresses for a server instance. Otherwise, URLs to the server can specify any of the host computer's IP address, any DNS name that maps to one of the IP addresses, or the localhost string.

• Listen Port

  Enter the port number from which you want to access the server instance. If you run multiple server instances on a single computer, each server must use its own listen port.

  Note:

  Do not set the listen port number to 7001; this is the default port for the Administration Server.

• SSL Listen Port

  Enter the port number from which you want to access the server instance for SSL connections - this column is only active if the corresponding SSL enabled checkbox in the same row is selected.

Click Switch Display to see the managed server information in tabs rather than in a table.

B.13 Configure Clusters Screen

A cluster consists of multiple managed server instances working together to provide increased scalability and reliability.

Use this screen to add or delete clusters; click Add to add a cluster. To delete a cluster, select the cluster name and click Delete.

For each cluster, specify:

• Name

  Name of the cluster.

• Cluster messaging mode

  If you are creating a cluster within a new WebLogic Server environment, Oracle recommends that you use the Unicast messaging type.

  If you are creating a cluster within an existing WebLogic Server environment or you need to ensure backward compatibility with older versions of WebLogic Server, you must use the Multicast messaging type. This enables multiple applications to subscribe to a given IP address and port number and listen for messages.

  Select "multicast" or "unicast" from the drop-down list. If you select "multicast" you must also provide:

  • Multicast address

    A multicast address is an IP address in the range from 224.0.0.0 to 239.255.255.255. The valid range is from 224.0.0.0 to 239.255.255.255. The default value used by WebLogic Server is 239.192.0.0. You should avoid using multicast addresses in the range x.0.0.1. This address must be unique to this cluster and should not be shared by other applications.

  • Multicast port

    The multicast port is used by cluster members to communicate with each other. Valid values are between 1 and 65535.

• Cluster address

  Address of the cluster.

Click Switch Display to see the cluster information in tabs rather than in a table.

B.14 Assign Servers to Clusters Screen

This screen only appears if you created at least one cluster on the Configure Clusters Screen.

Use this screen to assign each managed server in your domain to a cluster.

B.15 Create HTTP Proxy Applications Screen

An HTTP proxy server proxies requests from a web server to WebLogic Server instances in a cluster, and provides load balancing and failover for the proxied HTTP requests.

If you want to proxy requests for a cluster, select Create HTTP Proxy next to the cluster name, then select a proxy server from the drop-down list in the "Proxy Server" field.

B.16 Configure Machines Screen

A machine is the logical representation of the computer that hosts one or more WebLogic Server instances. Each Managed Server must be assigned to a machine. The Administration Server and Node Manager are used to manage the machines defined on this screen.

If you are creating a new machine on a non-UNIX operating system, specify the following:

• Name

  Name of the machine. This name is used to identify the machine within the WebLogic Server domain; it does not have to correspond to the machine's network name.

• Node manager listen address

  Enter the DNS name or IP address on which the Node Manager listens.

• Node manager listen port

  Enter the port number on which the Node Manager listens for incoming requests.

For UNIX machine, click the "Unix Machine" tab and specify the following:

• Name

  Name of the machine. This name is used to identify the machine within the WebLogic Server domain; it does not have to correspond to the machine's network name.

• Post bind GID enabled and Post bind GID

  Select Post bind GID enabled to specify a non-privileged group account under which the server instance runs, then enter the group in the Post bind GID column. The default group is nobody, which is a standard UNIX group ID that provides the least possible privileges. In a production environment, Oracle recommends that you create a group account specifically for running instances of WebLogic Server. .

• Post bind UID enabled and Post bind UID

  Select Post bind UID enabled to specify a non-privileged user account under which the server instance runs, then enter the user in the Post bind UID column. The default user is nobody, which is a standard UNIX account that provides the least possible privileges. In a production environment, Oracle recommends that you create a user account specifically for running instances of WebLogic Server.

• Node manager listen address

  Enter the DNS name or IP address on which the Node Manager listens.

• Mode manager listen port

  Enter the port number on which the Node Manager listens for incoming requests.

B.17 Assign Servers to Machines Screen

Use this screen to assign each WebLogic Server instance to the corresponding machine on which it runs.

B.18 Target Deployments to Servers or Clusters Screen

Use this screen to target your deployments to servers or clusters. Doing so enables WebLogic Server to serve the deployment to clients.

The Configuration Wizard automatically takes care of all necessary deployment targeting. You should not have to change anything on this screen unless specifically directed to do so.

In the left pane, select the server or cluster. Then, select the deployment in the right pane that you want to target to the selected server or cluster. The "Target" column in the right pane shows you the servers and clusters to which each deployment is targeted.

B.19 Target Services to Servers or Clusters Screen

Use this screen to target your deployments to servers or clusters. Doing so enables WebLogic Server to serve the deployment to clients.

The Configuration Wizard automatically takes care of all necessary services targeting. You should not have to change anything on this screen unless specifically directed to do so.

In the left pane, select the server or cluster. Then, select the service in the right pane that you want to target to the selected server or cluster. The "Target" column in the right pane shows you the servers and clusters to which each service is targeted.

B.20 Configure JMS File Stores Screen

Edit the configuration information for the JMS file stores, which are used to store persistent messages and durable subscribers.

• Name

  Alphanumeric (no spaces) name of your JMS file store. Each JMS file store configuration in your WebLogic environment must have a unique name, regardless of the domain or cluster in which it resides.

• Directory

  Directory where the JMS file store is located.

• Synchronous write policy

  Use the drop-down list to select one of the following for each file store:

  • Cache-Flush

    Transactions cannot complete until all of their writes have been flushed down to disk. This policy is reliable and scales well as the number of simultaneous users increases.

  • Direct-Write

    File store writes are written directly to disk. This policy is supported on Solaris and Windows. If this policy is set on an unsupported platform, the file store automatically uses the Cache-Flush policy instead.

  • Disabled

    Transactions are complete as soon as their writes are cached in memory, instead of waiting for the writes to successfully reach the disk. This policy is the fastest, but the least reliable (that is, transactionally safe). It can be much faster than the other policies, but power outages or operating system failures can cause lost or duplicate messages.

B.21 Configure RDBMS Security Store Database Screen

To make changs on this screen, select a database type from the drop-down list in the "Database Type" field. Then, select the appropriate driver in the "Driver" field.

Provide the following credentials for the selected database:

• DBMS SID

  The service ID of your database; this is usually the same as the global ID.

• DBMS Host

  The name of the system on which the database is running.

• DBMS Port

  The listen port number of the database.

• User Name

  The user name to access the database.

• User Password

  The password for the database user.

• Confirm User Password

  Re-enter the password for the database user.

Click Test Connection to make sure that the connection to your database is valid.

B.22 Configuration Summary Screen

Verify the information on this screen. In the Summary View field, select a category from the drop-down list to view information about that category:

• Deployment

  Shows the deployments that will be configured in each cluster and server. You can click on the name of a deployment to view detailed information about the selected deployment.

• Application

  Shows the applications that will be configured in each cluster and server. You can click on the name of an application to view detailed information about the selected application.

• Service

  Shows the services that will be configured in each cluster and server. You can click on the name of a service to view detailed information about the selected service.

• Cluster

  Shows the clusters that will be configured in this domain and the servers that will be configured in each cluster. You can click on each server name to view information specific to that server.

• Machine

  Shows the machines that will be configured in this domain and the servers that will be configured in each machine. You can click on each server name to view information specific to that server.

• JMS Server

  Shows the JMS file store information for each managed server.

Use the Previous button if you want to return to a previous screen to alter some portion of the configuration.
