Persistence Unit: Advanced Configuration

This page shows the advanced attributes of a persistence unit.

This page also allows you to create and configure DB Dictionaries and Query Caches.

The following considerations apply to DB Dictionaries:

If a DB Dictionary is defined in persistence.xml, it appears in the DB Dictionary table. If a DB Dictionary is defined in persistence.xml, you cannot delete it, but you can configure it via the Administration Console.
If a DB Dictionary is not defined in persistence.xml, you can create a new one from this page.
If a DB Dictionary is not defined in persistence.xml or you have not explictly created one, an internal default is used. The Kodo runtime configures the default DB Dictionary based on the Connection URL and Connection Drive attribues. This default DB Dictionary does not appear in the DB Dictionary table.

The following considerations apply to Query Caches:

If a Query Cache is defined in persistence.xml, it appears in the Query Cache table. If a Query Cache is defined in persistence.xml, you cannot delete it, but you can configure it via the Administration Console.
If a Query Cache is not defined in persistence.xml, you can create a new one from this page.
If a Query Cache is not defined in persistence.xml or you have not explictly created one, an internal default is used. The Kodo runtime configures the default Query Cache based on the Data Cache that you have configured. This default DB Dictionary does not appear in the DB Dictionary table.
