In the past few years, Oracle has released its latest version of Oracle Database: version 12c. Oracle Database 12c contains all the latest features, bug fixes, and security patches. Many applications built on Oracle Forms, ADF, APEX, or even non-Oracle applications rely on a connection to an Oracle database to query, insert, and update data.
When an Oracle database is upgraded to 12c, it is important to also upgrade or modernize your application to the latest version in order to decrease the possibility of compatibility issues occurring between your application(s) and your 12c Oracle database.
What you’ll learn in this article:
✓ Issues encountered when connecting to a 12c Oracle database
✓ The reason these errors occur
✓ Workarounds that may fix these errors
