You can check whether the landscape configuration is consistent and complete at any time. This allows you to check the effects of the configuration changes without activating them. Activate the configuration when you have made all necessary settings.
When you check the configuration, the output area shows the checks that are carried out. If the configuration is not consistent, the system issues a message telling you so. You can use information in this message to revise your configuration.
The system also checks the configuration when you activate it. If the configuration is consistent, the system updates the configuration files of the affected hosts and restarts the servers if necessary. If the configuration has errors, the output area displays appropriate messages and does not update the configuration files.
