8.2.3 Understanding the Exadata Software Image Version

The Exadata image version number contains the product version, a date code, and a build number.

The Exadata version installed on an Exadata storage server or an Exadata database server is determined with the imageinfo command. The image version of an Exadata release consists of three components. For example, if the command imageinfo -ver returns 25.2.11.0.0.260604.1, then:

• The product version is 25.2.11.0.0.

  Starting with Oracle Exadata System Software release 18.1, the first three digits in the product version represent: Year.Release.Update. The remaining digits are reserved for minor updates as required.

• The date code is 260604. The date code format is YYMMDD.

• The Oracle-internal build number is 1. This component is not always used.

In most circumstances it is sufficient to reference a release by using only the non-zero digits in the product version, for example 25.2.11. However, when updating, you need to consider the complete product version and date code of the installed and target releases.
