This chapter describes how to use the Change Center in Fusion Middleware Control. It also describes how to use Fusion Middleware Control to record WLST scripts, create notes, and customize table views.
This chapter includes the following sections:
The Change Center provides a way to lock a domain configuration so you can make changes to the configuration while preventing other accounts from making changes during your edit session.
When locking is enabled, you start the edit process by obtaining a lock. When you finish making changes, you save the changes. The changes do not take effect, however, until you activate them, distributing them to all server instances in the domain.
To make any changes to Oracle WebLogic Server using Fusion Middleware Control:
Locate the Change Center above the Target Navigation pane.
Select Changes, then select Lock & Edit to lock the editable configuration hierarchy for the domain.
This enables you to make changes using Fusion Middleware Control.
Make the changes you desire on the relevant pages within Fusion Middleware Control and click Save on each page where you make a change.
When you have finished making all desired changes, return to the Change Center and select Changes, then select Activate Changes.
For more information, see Configuration Options.
After you finish
Some changes you make in Fusion Middleware Control take place immediately when you activate them. Other changes require you to restart the server affected by the change. See View pending changes.
To view changes that you have saved, but which have not yet taken effect:
Locate the Change Center above the Target Navigation pane.
Select Changes, then select either View Change List or View Restart Checklist.
The Change List or Restart Checklist page is displayed.
From the Change List page, you can view all changes that have been saved, but not yet activated.
From the Restart Checklist page, you can view all server instances that must be restarted for configuration changes to take effect.
To restart a server:
In the Restart Checklist table, select the row of the server you want to restart.
Click Restarts.
Click Done.
The Change Center provides a way to lock a domain configuration so you can make changes to the configuration while preventing other accounts from making changes during your edit session.
To enable or disable the domain configuration locking feature in a development domain:
Locate the Change Center above the Target Navigation pane.
Select Changes, then select Preferences.
The Change Center Preferences page is displayed.
From the Change Center Preference page, select or clear the Auto-Commit Mode (Automatically Acquire Lock and Activate Changes) field to enable or disable this feature.
Click OK.
To verify that domain configuration locking is enabled:
Locate the Change Center above the Target Navigation pane.
Select Changes, then locate Auto-Commit Mode.
If a blue checkmark appears next to Auto-Commit Mode, the domain configuration lock is enabled.
If there is no checkmark, select Auto-Commit Mode to enable the domain configuration lock.
A confirmation message is displayed on the page.
After you finish
When you enable domain configuration locking, you must use the Change Center to unlock and edit the domain configuration. See Use the Change Center.
When you select Lock & Edit in the Change Center, you obtain a lock on the editable configuration hierarchy which prevents other people from making changes until you release the configuration lock.
To release the configuration lock:
Locate the Change Center above the Target Navigation pane.
Select Changes, then select one of the following options:
To release the lock explicitly before you make any changes, select Release Configuration.
To release the lock implicitly after you save any changes, select Activate Changes or Undo All Changes.
A confirmation message is displayed on the page indicating the configuration lock has been released.
You can specify individual Change Center preferences.
To specify preferences for the Change Center:
Locate the Change Center above the Target Navigation pane.
Select Changes, then select Preferences.
The Change Center Preferences page is displayed.
From the Change Center Preference page, you can specify the following options:
Activation Timeout
Warn User Before Taking Lock
Auto-Commit Mode (Automatically Acquire Lock and Activate Changes)
Management Operation Timeout
Click OK.
A confirmation message is displayed on the page.
To help automate the task of configuring a domain, you can record your configuration actions in Fusion Middleware Control as a series of WebLogic Scripting Tool (WLST) commands and then use WLST to replay the commands.
WLST is a command-line scripting environment that you can use to create, manage, and monitor WebLogic Server domains.
You cannot record WLST commands for the following:
Changes to the security data that is maintained by a security provider. For example, you cannot record the commands to add or remove users, roles, and policies.
Changes to deployment plans.
Deployment operations: deploy, redeploy, undeploy, start, stop.
Runtime operations found on Control or Monitoring pages, such as starting and stopping applications or server instances.
For more information, see Configuration Options.
This section includes the following tasks:
You can only record actions that modify a domain's configuration document. See Record WLST scripts.
To start recording your Fusion Middleware Control actions as WLST commands:
Locate the Change Center above the Target Navigation pane.
Select Recording, then select Start Recording.
A confirmation message is displayed on the page.
After you finish
Fusion Middleware Control starts recording all actions that change the domain's configuration. As it records each command, it writes the command to the script file that you specified in your recording preferences. See Set WLST recording preferences.
To stop recording your Fusion Middleware Control actions as WLST commands:
Locate the Change Center above the Target Navigation pane.
Select Recording, then select Stop Recording.
A confirmation message is displayed on the page indicating that Fusion Middleware Control has stopped recording your actions.
To view the commands that have been recorded in your script file:
Locate the Change Center above the Target Navigation pane.
Select Recording, then select View Recording.
The View Recording page shows the commands that have been recorded into the script file in the current and previous recording sessions.
You cannot edit the commands that are displayed on this page. Instead, you can use a text editor to edit the commands in the script file.
Click OK.
You can specify individual preferences for WLST recording.
To set preferences for recording WLST scripts:
Locate the Change Center above the Target Navigation pane.
Select Recording, then select Preferences.
The Set Preferences for WLST Recording page is displayed.
From the Set Preferences for WLST Recording page, you can specify the following options:
Base Script Directory
Script File Name
Append to File
