oraInst.loc points to an Inventory that does not exist

Problem:

/etc/oraInst.loc points to an Inventory that does not exist:

mkdir : No such file or directory at ./adclone.pl line 1274

ERROR: Failed to execute ./adclone.pl


Solution: Step -1 

/home/applprod

Step-2

/etc/oraInst.loc 

/home/applprod/oraInventory - previously it was /home/oraprod/oraInventory

(or)
As root user, run /tmp/orainstRoot.sh.

Rerun clone again, but it failed.

The root directory had completely filled up because the backup was restored to /oracle and not /u0/oracle.
Removed /oracle, then reran /tmp/orainstRoot.sh and tried script again.
