Enter the full path to the domain that you want to reconfigure, for example, C:\domains\mydomain. You can also use the Browse button to navigate to the domain directory.


Reconfiguration Setup Progress

Surrounding text describes setupprogress.gif.

This screen displays the progress of the setup process. During this process:

  • WLS core infrastructure files are updated

  • The WebLogic domain configuration is read

  • Reconfiguration templates for your installed products, including Fusion Middleware products, are automatically applied. This updates various domain configuration files such as config.xml, config-groups.xml, and security.xml (among others).

  • Schemas, scripts, and other such files that support your Fusion Middleware products are updated.

  • The domain upgrade is validated.

Click Next to continue. The Domain Mode and JDK screen is displayed.

After configuring the domain mode and selecting the JDK, subsequent screens depend on the contents of the domain, and differ for each domain.

Domain Mode and JDK

Proxy Server

This drop-down list contains all Managed Servers that are not assigned to a cluster. Select the Managed Server on which to deploy the proxy application.

A proxy application named OracleProxy4_clustername_servername is created and deployed on the Managed Server.


Coherence Clusters

Description of coherencecluster.gif follows
Description of the illustration coherencecluster.gif

This screen is displayed only if you included Coherence in the WebLogic Server installation. It lists the Coherence cluster that is automatically added to the domain.

Column Description

Name

Accept the default cluster name or type a new name for the Coherence cluster.

When updating a domain, if you have added additional Coherence clusters to the domain via WLST or the Administration Console, they are also listed here.

Coherence Listen Port

Enter the port number to use as the Coherence cluster listen port.


When including a Coherence cluster in a domain:

  • All Managed Servers and clusters that you configure in the domain during the current Reconfiguration Wizard session or future Configuration Wizard sessions are automatically added to the Coherence cluster.

  • Servers and clusters that already exist in the domain prior to running the Reconfiguration Wizard are automatically assigned to the Coherence cluster.

  • When reconfiguring a domain, if the domain contains a only an Administration Server and no Managed Servers, the Administration Server is automatically assigned to the Coherence cluster. If, however, at least one Managed Server exists in the domain, the Administration Server is not assigned to the Coherence cluster.

  • If there are multiple Coherence clusters in the domain (for example, you added a second Coherence cluster via WLST or the Administration Console), any servers or clusters that you subsequently add to the domain via the Reconfiguration Wizard are automatically assigned to the first Coherence cluster that is listed on the Coherence Clusters screen.

Machines

Description of machines.gif follows
Description of the illustration machines.gif

In a WebLogic domain, the machine definitions identify physical units of hardware and are associated with the WebLogic Server instances or system components (such as OHS servers) that they host.

Use this screen to add or delete machines, or to modify the settings for an existing machine. Each machine has the following configuration settings.

Select the Machine tab (for Windows) or the UNIX Machine tab (for UNIX).

Column Description

Name

Enter a valid machine name. The machine name is used to identify the machine within the WebLogic domain; it does not have to match the network name for the machine. The name must be unique among all component names within the domain.

Node Manager Listen Address

Select a value from the drop-down list for the listen address used by Node Manager to listen for connection requests. By default, the IP addresses defined for the local system and localhost are shown in the drop-down list. The default value is localhost.

If you specify an IP address for a machine that hosts the Administration Server and you need to access the WebLogic Server Node Manager, you must disable host name verification.

For more information, see "Using Host Name Verification" in Administering Security for Oracle WebLogic Server.

Node Manager Listen Port

Enter a valid value for the listen port used by Node Manager to listen for connection requests.

The valid Node Manager listen port range is from 1 to 65535. The default value is 5556.

Post bind GID enabled

(UNIX machines only) Select this check box to enable a server running on this machine to bind to a UNIX group ID (GID) after it finishes all privileged startup actions. By default, this check box is not selected.

Post bind GID

(UNIX machines only) Enter the UNIX group ID (GID) under which a server on this machine will run after it finishes all privileged startup actions. Otherwise, the server continues to run under the group from which it was started. For this setting to take effect, you must select the Post bind GID enabled check box.

Post bind UID enabled

(UNIX machines only) Select this check box to enable a server running on this machine to bind to a UNIX user ID (UID) after it finishes all privileged startup actions. By default, this check box is not selected.

Post bind UID

(UNIX machines only) Enter the UNIX user ID (UID) under which a server on this machine will run after it finishes all privileged startup actions. Otherwise, the server continues to run under the account from which it was started. For this setting to take effect, you must select the Post bind UID enabled check box.


You might want to create machine definitions in situations such as the following:

  • The Administration Server uses the machine definition, with the Node Manager application, to start remote servers.

  • WebLogic Server or other system components such as OHS use configured machine names when determining the server in a cluster that is best able to handle certain tasks, such as HTTP session replication. Those tasks are then delegated to the identified server.

    Note:

    You must configure machines for each product installation that runs a Node Manager process. The machine configuration must include values for the listen address and port number parameters.

Click Add to add a new machine. The default name for a new machine is new_[Unix]Machine_n, where n starts at 1 and increments by 1 for each machine that you add.

Click Delete to delete an existing machine.

Assign Servers to Machines

Description of assign_srv_to_mach.gif follows
Description of the illustration assign_srv_to_mach.gif

Use this screen to assign WebLogic Server instances to each of the machines you defined.

  1. In the Machine list box, select the Windows or UNIX machine to which you want to assign a WebLogic Server instance.

  2. Assign WebLogic Server instances to the selected machine in one of the following ways:

    • Double-click the WebLogic Server instance in the Server list box.

    • Select the appropriate WebLogic Server instance in the Server list box and click the right arrow.

    • Shift+click to select multiple servers in the Server list box; then, click the right arrow.

    The name of the WebLogic Server instance is removed from the Server list box and added, below the name of the target machine, in the Machine list box.

  3. Repeat steps 1 and 2 for each WebLogic Server instance to assign to a machine.

  4. Review the machine assignments.

    If necessary, you can remove a WebLogic Server instance from a machine in one of the following ways:

    • Double-click the name of the appropriate WebLogic Server instance in the Machine list box.

    • Select the appropriate WebLogic Server instance in the Machine list box and click the left arrow.

    The name of the WebLogic Server instance is removed from the Machine list box and restored to the Server list box.

Deployments Targeting

Description of target_deployments.gif follows
Description of the illustration target_deployments.gif

Use this screen to target applications for deployment on servers or clusters.

Applications associated with the product for which you are configuring the domain are targeted automatically to the Managed Server created for that product or to the cluster to which that Managed Server is assigned. In this screen, you can target applications to additional servers and clusters.

To target an application deployment to a cluster or server:

  1. In the Target list box, select the cluster or server on which you want to deploy applications.

    The name of the selected target is displayed as the title of the list box on the right.

  2. In the target_name list box, select the check boxes corresponding to the applications to deploy on the selected target.

    The applications displayed here vary, depending on the products that you selected in the Select Domain Source screen, earlier in the wizard.

    Note:

    When you select a Managed Server in the Target list box, some of the check boxes in the target_name list box might be disabled, indicating applications that are already targeted at the cluster that contains the selected Managed Server.

    After you select applications, the names of the targeted clusters and servers are displayed in the Target column in the target_name list box.

  3. Repeat steps 1 and 2 for the other clusters and servers, as required.

  4. After making the required selections, click Next.

When you reconfigure a domain, if you delete a Managed Server or cluster to which applications are currently targeted, the Reconfiguration Wizard automatically retargets those applications as follows:

  • If the applications were originally targeted solely to the Managed Server or cluster that you are now deleting (that is, after you delete the Managed Server or cluster, the applications would become untargeted in the modified domain), then the Reconfiguration Wizard automatically retargets the applications to all eligible targets.

    An eligible target is any cluster or Managed Server that is not defined in the configuration groups specification (config-groups.xml file) of an included template. Servers or clusters that are specified in config-groups.xml are essentially owned by the template and, therefore, are not eligible for automatic targeting.

  • If the applications were originally targeted to multiple targets (including Managed Servers, clusters, and the Administration Server), and one of the targeted Managed Servers or clusters is deleted, then, in the extended domain, the Reconfiguration Wizard leaves the remaining target associations intact and does not attempt to retarget the applications.

Services Targeting

Description of servicestargeting.gif follows
Description of the illustration servicestargeting.gif

Use this screen to target services to the appropriate Managed Servers or clusters.

Services that are associated with the product for which you are configuring the domain are targeted automatically, to the Managed Server created for that product or to the cluster to which that Managed Server is assigned. In this screen, you can target services to additional servers and clusters.

To target services to Managed Servers or clusters:

  1. In the Target list box, select the cluster or server on which you want to deploy services.

    The name of the selected target is displayed as the title of the list box on the right.

  2. In the target_name list box, select the check boxes corresponding to the services to deploy on the selected target.

    The services displayed here vary, depending on the products that you selected in the Select Domain Source screen earlier in the wizard.

    Note:

    When you select a Managed Server in the Target list box, some of the check boxes in the target_name list box might be disabled, indicating services that are already targeted at the cluster that contains the selected Managed Server.

    After you select services, the names of the targeted clusters and servers are displayed in the Target column in the target_name list box.

  3. Repeat steps 1 and 2 for the other clusters and servers, as required.

  4. After making the required selections, click Next.

When you reconfigure a domain, if you delete a Managed Server or cluster to which services are currently targeted, the Reconfiguration Wizard automatically retargets those services as follows:

  • If the services were originally targeted solely to the Managed Server or cluster that you are now deleting (that is, after you delete the Managed Server or cluster, the services would become untargeted in the modified domain), then the Reconfiguration Wizard automatically retargets the services to all eligible targets.

    An eligible target is any cluster or Managed Server that is not defined in the configuration groups specification (config-groups.xml file) of an included template. Servers or clusters that are specified in config-groups.xml are essentially owned by the template and, therefore, are not eligible for automatic targeting.

  • If the services were originally targeted to multiple targets (including Managed Servers, clusters, and the Administration Server), and one of the targeted Managed Servers or clusters is deleted, then, in the extended domain, the Reconfiguration Wizard leaves the remaining target associations intact and does not attempt to retarget the services.

JMS File Stores

Description of jms_file_stores.gif follows
Description of the illustration jms_file_stores.gif

A JMS file store is a disk-based file in which persistent messages can be saved.

Use this screen to modify the JMS file stores that are configured in your domain. It contains the following fields.

Column Description

Name

Enter a valid name for the JMS file store. The name must be a string of characters. The name of the JMS file store must be unique among all component names within the domain.

Directory

Enter the path of the directory (in your system) in which the JMS file store resides.

Synchronous write policy

From the drop-down list, select one of the following synchronous write policies to determine how the file store writes data to the disk.

If the JMS file store is used exclusively for paging non-persistent messages to the disk, the synchronous write policy is ignored.

Cache-Flush

WebLogic Server enables the default file write behavior of the operating system and storage device, which typically includes caching and scheduling file writes, but forces a flush of the cache to disk before completing a transaction.

For more information, see "Cache-Flush Policy" inAdministering Server Environments for Oracle WebLogic Server.

Direct Write

WebLogic Server writes synchronously to a primary set of files in the location defined by the Directory attribute of the file store configuration using a native I/O wlfileio driver.

For more information, see "Direct-Write Policy" in Administering Server Environments for Oracle WebLogic Server

Direct-Write-With-Cache

For most scenarios, Oracle recommends using the Direct-Write-With-Cache policy. When this policy is selected, WebLogic Server writes synchronously to a primary set of files in the location defined by the Directory attribute of the file store configuration using a native I/O wlfileio driver.

For more information, see "Direct-Write-With-Cache Policy" in Administering Server Environments for Oracle WebLogic Server.

Disabled

WebLogic Server relies on the default file write behavior of the operating system and storage device.

For more information, see "Disabled Policy" in Administering Server Environments for Oracle WebLogic Server.

Direct-Write

Write operations are performed directly to the disk. This policy is supported on Solaris and Windows. If this policy is active on an unsupported platform, the file store switches automatically to the cache-flush policy.

For more information, see "Direct-Write Policy" in Administering Server Environments for Oracle WebLogic Server

Disabled

Transactions are complete as soon as the writes are cached in memory. When this policy is active, completion of transactions does not depend on waiting for writes to reach the disk.

This setting affects performance, scalability, and reliability.


Configuration Summary
