what is the oraInventory ?

OraInventory is directory which store the information all the oracle software products installed on all Oracle_Homes on a machine.
In a 11i Application system the RDBMS and iAS ORACLE_HOMEs are registered in the oraInventory. The 806 ORACLE_HOME, which is not managed through OUI, is not.

On Unix/Linux, the location of the oraInventory is defined by the content of oraInst.loc, at:
- /var/opt/oracle/oraInst.loc on Solaris, HP-UX and Tru64
- /etc/oraInst.loc on Linux and AIX
On Windows, the location of the oraInventory is defined by the value of the registry key HKEY_LOCAL_MACHINE|Software\Oracle\INST_LOC or if this value is not defined, at C:\Program Files\Oracle\Inventory.
=> Before OUI 2.X, the oraInventory was binary.
=> Starting with OUI 2.X and 11.5.8, the information in the inventory is stored in Extensible Markup Language (XML) format. It is called XML oraInventory.
XML inventory is divided into 2 distinct components:
  • Global (or Central) Inventory
  • Local (or Home) Inventory
