After you have created an Application Data Model (ADM), you can select additional databases to be associated databases of an ADM, as explained in the following procedure. See "Creating an Application Data Model" for instructions on creating an ADM.
To associate a database to an ADM:
From the Application Data Models page, select an ADM, select Actions, then Associated Databases.
This dialog lists all of the databases associated with this ADM and the schemas assigned to each application per database. You can add more databases that give you a choice of data sources when subsetting and databases to mask during masking.
Click Add, then select a database from the pop-up.
The selected database now appears in the Database section of the Associated Databases dialog.
To change a schema, select the associated database on the left, select the application on the right for which the schema is to be changed, then click Select Schema.
Select the missing schema from the list in the pop-up, then click Select.
