Central Configuration¶

The Central Configuration is where all global settings for a Domino installation are enumerated. You can access the Central Configuration interface from the Admin portal by clicking Advanced > Central Config.

The interface is organized into a list of records. You can click on an existing record to edit its attributes, or you can add a record with the Add Record button at top right. If there is no record explicitly set for an option, the default value will be used. In order for changes made in the Central Config to take effect, you must to restart Domino services using the link at the top of the interface.
