OUI-15038: Unable to execute rule 'CheckCentralInventoryLocation' OR OPatch failed to locate Central Inventory
This happend during application of the CPU aka SPU i.e. SPU Jan 2013. While running the OPatch on the oracle home we hit the wall.As a standard practice we run the pre-requisite checks on any Oracle Home / DB which needs to be patched and we ran into folliwng errors.

So, clearly the issue was with the central inventory location. So I decided to point to central inventory for OPatch. and ran the check with following flag
#./opatch prereq CheckConflictAmongPatchesWithDetail -phBaseDir /home/oracle/14841409
This also failed with following error
OPatch failed to locate Central Inventory.
Possible causes are:
The Central Inventory is corrupted
The oraInst.loc file specified is not valid.
Recommendation: Check if the oraInst.loc specified is correct or use OUI AttachHome feature to attach the home to the Central Inventory
So something is amiss and decided to look into the inventory.xml. However, the inventory looks fine and still something not right. Now if you read the above error carefully it also tells you, how to fix it!!
Now I had two ways, possibly, to fix the problem.
1. Either to re-create the central inventoy (which looks preeety dicy to me as this was shared server with other application groups)
2. OR to simpley try to reattach the home and see if that fix the problem.
I decided to go with option 2 and again I have two choices to fix it.
1. Either run the attachHome script from Problem ORACLE_HOME
OR
2. run the following command to fix it.
Command -
However there is a problem with above command. To use it I need to have the name of ORACLE_HOME. Hence in the case where my inventory is corrupted, it is very difficult to find out the correct name for ORACLE_HOME.
So I simply decided to run the attachHome from ORACLE_HOME
#$ORACLE_HOME/oui/bin/attachHome.sh
And when I ran the opatch again the issue was resolved.
