There are no patches that need to be applied from the patchset Oracle Application Server PatchSet 10.1.3.5.0

Getting the following error while upgrading iAS to patchset 10.1.3.5.0.

"There are no patches that need to be applied from the patchset Oracle Application Server PatchSet 10.1.3.5.0"

The reason for this error is that the Global inventory and Local inventory data of this instance is corrupt. Hence the patchset 'runInstaller' command couldn't find the correct inventory information of 1013_ORACLE_HOME on this instance, then got the above error message.

Note: Due to this issue, users cannot upgrade iAS to patchset 10.1.3.5.0. This will cause delay to their project schedule

Solution to this issue is that
1. Confirm there is the instance inventory folder :
/.../[sid]/inst/apps/[sid]_[hostname]/admin/oraInventory

2. Create oraInst.loc file under 1013_ORACLE_HOME. Edit oraInst.loc to add the following line and save it:
inventory_loc=/.../[sid]/inst/apps/[sid]_[hostname]/admin/oraInventory

3. Since there is the valid and correct Local Inventory under 1013_ORACLE_HOME, invoke the 10.1.3.5.0 patchset runInstaller program by running the command:
$ ./runInstaller -invPtrLoc [1013_ORACLE_HOME]/oraInst.loc
