File ownership after patching or relinking Oracle RDBMS software
Some time ago I received the warning message “chmod: changing permissions of ‘/u00/app/oracle/product/11.2.0.4/bin/extjobO’: Operation not permitted” when patching the Oracle RDBMS at a customer site. This was the reason for me, to check what happens to file permissions and ownership when patching or relinking Oracle RDBMS software.
