The Oracle Universal Installer inventory stores information about all Oracle software products installed in all Oracle homes on a host, provided the product was installed using Oracle Universal Installer.
Inventory information is stored in Extensible Markup Language (XML) format. The XML format enables easier diagnosis of problems and faster loading of data. Any secure information is not stored directly in the inventory. As a result, during removal of some products, you may be prompted to enter the required credentials for validation.
For more information, see "Oracle Universal Installer Inventory" in the Oracle Universal Installer and OPatch User's Guide in the Oracle Database documentation library:

Note: Oracle recommends placing the central inventory on a local file system that is not shared by other systems, since the central inventory is a system-specific inventory of the installations on this system. It is strongly recommended that you place the central inventory on a local disk so that installations from other systems do not corrupt the inventory. You should not place the central inventory in the Oracle Base.
