Admin Interface No Longer Selects a Default Schemas Database
As of MarkLogic 9, you can create a database without an associated schemas database. Earlier versions of MarkLogic required you to specify a schemas database when creating a new database. This change has no impact on users creating databases through the Admin API. However, this change affects the database creation page of the Admin Interface as follows:
The Admin Interface no longer automatically selects the pre-defined Schemas database as the schemas database when you create a database through the UI. Instead, you must explicitly select a schemas database or else you will create a database with no associated schemas database.
Depending on the uses to which you put the database, some operations might fail if there is no associated schemas database. For example, features such as temporal document management and template driven extraction require a schemas database to be associated with the content database.
