Oracle service Database

Start by examining how the library lists worksheet connections and represents the protected attributes under _connectionXML. Reproduce a workbook migration containing an Oracle connection whose service differs between environments, then trace why the service is absent from the database name. Done means the service can be changed during a code-based migration and the resulting workbook retains the intended connection.

Migrating a workbook that contains an oracle connection from one environment to another one through code is not possible if the "service" is different,
The service in oracle is equivalent to the database name but when we list the worksheet connections the database name comes up empty. The information about the service is under "protected attributes" under _connectionXML in the attrib.
So there is no way to change it
