Configuration States and Behavior

After you finish creating or modifying a configuration, you must save and activate the configuration before the Oracle® Enterprise Session Border Controller (E-SBC) saves the changes to the running configuration.

At any time, the following three versions of the configuration can exist on the E-SBC.

• Editing. The editing configuration is the version that you are making changes to from the Web GUI. The editing version is stored in the E-SBC volatile memory. The editing version cannot survive a system reboot.
• Saved. The saved configuration is the version of the editing configuration that the system copies into the non-volatile memory when you click Save on the Web GUI. Until you activate the saved configuration, the changes do not take effect on the E-SBC. The system does not load the saved, but not activated, configuration as the running configuration on reboot.
• Running configuration. The running configuration is the configuration that the system is using. When you activate the saved configuration it becomes the running configuration. Most configuration changes can take effect upon activation. Some configuration changes require a system reboot. On reboot, the system loads the running configuration.

The process for saving and activating a configuration, includes the following steps.

1. OK. All configuration dialogs display an OK button that saves changes to the editing memory. If you reboot before the next step, the E-SBC does not save the changes.
2. Save. The Save button on the Web GUI toolbar verifies the configuration, displays errors, saves the current configuration to the last-saved configuration, and stores it on the E-SBC. The system displays any errors at the bottom of the Configuration page. If you reboot after saving the changes, the E-SBC retains the changes and moves the changes to the running configuration.
3. Activate. After you finish making one or more configuration changes, OK and Save from the last configuration dialog that you need to edit at this time. The system displays the Confirmation dialog containing the Activate button. When you click Activate, the E-SBC activates all of the saved configuration changes and saves the new configuration to the running configuration. If you cancel the activation function, the E-SBC saves the configuration in a file and does not change the running configuration. You can continue to make changes to the configuration.
