Update Physical Layer Wizard in OBIEE

This wizard allows you to update database objects in the Physical layer of a repository based on their current definitions in the back-end database.

When the wizard processes the update, the server running the Administration Tool connects to each back-end database. The objects in the Physical layer are compared with those in the back-end database. 

Explanatory text alerts you to differences between objects as defined in the database in the Physical layer and as defined the back-end database, such as data type-length mismatches and objects that are no longer found in the back-end database. For example, if an object exists in the database in the Physical layer of the repository but not in the back-end database, the following text is displayed:

"Object does not exist in the database"
