Inventory load failed... OPatch cannot load inventory for the given Oracle Home.
Possible causes are:
   Oracle Home dir. path does not exist in Central Inventory
   Oracle Home is a symbolic link
   Oracle Home inventory is corrupted
LsInventorySession failed: OracleHomeInventory gets null oracleHomeInfo
OPatch failed with error code 73

Reason :
======

The Central Inventory is pointing to Wrong location and also the path inside the Inventory may points to PROD. So just change the inventory location to point to TEST and also check whether it presents.

Solution:
=========

Change the Location points to TEST in the following 

$ cat /etc/oraInst.loc
/test/oracledb/db/tech_st/11.1.0/admin/oui/TEST_test/oraInventory

$ pwd
/test/oracledb/db/tech_st/11.1.0/admin/oui/TEST_test/oraInventory/ContentsXML

$ cat inventory.xml_bkp |grep PROD


Change the following path points to TEST

$ cat inventory.xml |grep PROD
