Oracle versions numbers can be very long. Complicating matters further, different product families within Oracle use the version hierarchy
differently. This can make it confusing to determine whether a specific product update has been certified with Oracle E-Business Suite.
Oracle Database update numbers can be daunting. However, it might be reassuring to learn that the fifth-level digit in Oracle Database version is not relevant to E-Business Suite certifications. In other words, you can apply any database patchsets that have been certified at the fourth-level digit.
For example, we have certified EBS 12.2 with Database 22.214.171.124. All of the following Oracle Database patchsets will work with EBS 12.2:
This is sometimes shown in our documentation in either of the following ways:
The absence of a fifth-digit or the presence of an 'X' in the fifth digit's place means any fifth-digit level updates may be applied to an Oracle Database for EBS 12.2 without requiring a new certification. This applies to all environments, including test and production environments.
