Fixing the Dreaded *.mk Error in DBD::Oracle insalls

If you have ever had this message: Unable to locate an oracle.mk, proc.mk or other suitable *.mk file in your Oracle installation. (I looked in…) It can be a very frustrating one to track down. There is no 100% answer for this problem but there seems to be two main scenarios where I have encountered this and have come up with somewhat of a solution, here it is.

Cloning Oracle Home from RAC to Stand-Alone

I cloned Oracle software before and it is a simple process: tar $ORACLE_HOME, copy the tar file to the new server, untar, run the cloning script which will register the new home with the inventory, and you are done! In theory, at least. Here is what actually happened:

Applying Oracle 11.2 April 2010 PSU for Single-Instance ASM and DBMS

I saw that PSU 9343627 was released and gave it a whirl. I was a little confused when the README seemed to contain a lot of instructions that always assumed it to be on a clustered, RAC install. My setup was a single-instance Grid Infrastructure installation just to provide ASM. I soon met problem upon problem when going through first this setup step.
