ORACLE_BASE when installing GRiD
The installer asks for a place to put the new GRID software, and makes a suggestion for that.
It specifies ORACLE_BASE in the format of: /u01/app/<<software owner>> (typically "grid")
It suggests an ORACLE_HOME of: /u01/app/11.2.0/grid
Note that the suggested ORACLE_HOME for the grid install, does not live inside the suggested ORACLE_BASE.
This seems to be different than what happens when installing/upgrading the DBMS software.
In the DBMS install ORACLE_BASE will be specified like : /u01/app/oracle
and then an ORACLE_HOME is suggsted that lives on top of ORACLE_BASE: /u01/app/oracle/product/11.2.0.3/dbhome_1
