Oracle Universal Installer Evidences (OUI) are a cause for false positives.
FlexNet Manager, for licensing purposes, cannot trust OUI data for Oracle Options (that are collected by the Oracle Inventory scripts and are set as used after multiple queries).
As of the ARL Update of December 24th, OUI installer evidences will be intentionally ignored. You will be able to see the raw evidences from the Inventory Devices (or unrecognized evidences devices tab), but these evidences will no longer trigger application recognition for Oracle Options.
Regarding Oracle Database, OUI evidences will also leave false positives (when the database are upgraded, for instance) and cause many “unspecified editions” installations.
Considering that OUI evidence could still be a sign that the Oracle inventory failed for all instances on a server, the precedence rules for Oracle will be modified the following way:
Oracle Unspecified will be removed by any later Oracle Database Standard or Enterprise Edition version. Thus, all false positives due to upgrades will be removed.
If Oracle Installer says Oracle Database is installed, but the instance is inventoried on the server, Oracle Unspecified Edition installation will warn on a possible Oracle Inventory issue.
OUI Evidence spreadsheet is attached for reference.
