1. What is the pre-req for applying a rdbms patch?
Ans : OraInventory should be set in file oraInst.loc @/var/opt/oracle or /etc

Ans: The oraInventory is the location for the OUI (Oracle Universal Installer)’s bookkeeping. The orainventory stores information about: All Oracle software products installed in all ORACLE_HOMES on a machine Other non-Oracle products, such as the Java Runtime Environment (JRE). 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.

4. What is Global orainventory?
Ans : The Global oraInventory is the part of the XML inventory that contains the high level list of all oracle products installed on a machine. There should therefore be only one per machine. Its location is defined by the content of oraInst.loc.The Global OraInventory records the physical location of Oracle products installed on the machine, such as ORACLE_HOMES (RDBMS and IAS) or JRE. It does not have any information about the detail of patches applied to each ORACLE_HOMEs.The Global OraInventory gets updated every time you install or de-install an ORACLE_HOME on the machine, be it through OUI Installer, Rapid Install, or Rapid Clone.
Note: If you need to delete an ORACLE_HOME, you should always do it through the OUI de-installer in order to keep the Global OraInventory synchronized.
5. What is local Orainventory?
Ans : There is one Local OraInventory per ORACLE_HOME. It is physically located inside the ORACLE_HOME at $ORACLE_HOME/inventory and contains the detail of the patch level for that ORACLE_HOME.The Local OraInventory gets updated whenever a patch is applied to the ORACLE_HOME, using OUI.
