Clinging to outdated data access technologies can expose your business to significant risks. If your VB6 applications still rely on Oracle Objects for OLE (OO4O), it’s time to face a hard truth: Oracle has moved on.
Oracle officially deprecated OO4O with the release of Oracle Database 11g. In fact, Oracle 11g Release 2 was the last version to include and support OO4O. With the advent of Oracle Database 12c, Oracle made a decisive break—OO4O was completely removed from the database suite. This means that any application still using OO4O will face immediate compatibility issues if upgraded beyond Oracle 11g.
OO4O was widely used for VB6 applications interacting with Oracle databases, but with its deprecation, businesses now face:
For businesses still running legacy VB6 applications, the best path forward is to modernize and migrate to .NET while adopting Oracle Data Provider for .NET (ODP.NET).
Oracle’s answer to the challenges posed by OO4O is Oracle Data Provider for .NET (ODP.NET). Unlike OO4O, ODP.NET is actively maintained and updated to support the latest Oracle Database features. Oracle has consistently released new versions, such as the ODP.NET 23c Developer Release in mid-2023 and the managed ODP.NET driver version 23.7.0 in December 2024.
