Identifying Your Oracle Database Software Release (21)

Because Oracle Database continues to evolve and can require maintenance, Oracle
periodically produces new releases. Not all customers initially subscribe to a new
release or require specific maintenance for their existing release. As a result, multiple
releases of the product exist simultaneously.

As many as five numbers may be required to fully identify a release. The significance
of these numbers is discussed in the sections that follow.

To understand the release nomenclature used by Oracle, examine the following
example of an Oracle Database server labeled "Release 10.1.0.1.0".
