The Replication Agent ltl_character_case configuration parameter controls the case in which the Replication Agent sends database object names to the primary Replication Server.
For example, if a replication definition is created for all tables named testtab, the table name sent by the Replication Agent must be testtab, or no match occurs. Because Replication Server is case-sensitive, a value of TESTTAB does not match a value of testtab.
If you create replication definitions, choose a default case (for example, create all replication definitions in either all uppercase or all lowercase), and change the value of the Replication Agent ltl_character_case parameter to match.
In an Oracle database, object names are stored, by default, in all uppercase, if no case was forced when the object was created. The Replication Agent sends object names in uppercase to the primary Replication Server, unless configured to do otherwise.
For more information about the ltl_character_case parameter, see the Replication Agent Administration Guide.
