Edition Based Redefinition (EBR) is a new feature introduced from Oracle Software Version 11g R2.Edition-based redefinition allows multiple versions of PL/SQL objects, views and synonyms in a single schema.This feature facilitates Online patching of database objects in R12.2 online Patching.
Editionable and Non-editionable Objects
Below schema object types are editionable in the database:
SYNONYM
VIEW
SQL translation profile
All PL/SQL object types:
FUNCTION
LIBRARY
PACKAGE and PACKAGE BODY
PROCEDURE
TRIGGER
TYPE and TYPE BODY
If a schema object type is editionable in the database, then it can be editionable in schemas.All other schema object types are noneditionable in the database and in every schema, and objects of that type are always noneditioned. Tables are always noneditioned objects.
To view the editions related information in the database, use the below datadictionary tables.
DBA_EDITIONS: SELECT * FROM dba_editions;
DBA_OBJECTS_AE: DBA_OBJECTS_AE view shows all objects, of all editions.
