Flexibility in Partitioning Database Files

The value of the partitioned attribute is maintained in the database control file, to enable the setting to vary in different instances of the database. This means that when a JADE application is deployed to different sites, some installations could have a selection of database files partitioned while others have a different selection or no partitioned files.

With such flexibility, there is the potential for consistency issues at deployment time if an evolved schema were to violate the file partitioning rules. To help avoid such issues, you can set a partitionable attribute for a DbFile instance, to indicate that the associated database map file is a candidate for partitioning.
