Oracle Base and Software Location in installation of GI

Hi all,

Some documentation of OTN say that Oracle recommended that the installation location for GI should be into its own directory path because root.sh will change the ownership to root:oinstall entire path, but there are some documentation that this is not mentioned and the installation path is different:

bad:

# mkdir -p /u01/app/grid <- oracle base of grid

# mkdir -p /u01/app/grid/11.2.0 <- software location installation of grid, this is Grid Home

# mkdir -p /u01/app/oracle <- oracle base of rdbms

good:

# mkdir -p /u01/app/grid <- oracle base of grid

# mkdir -p /u01/app/11.2.0/grid <- software location installation of grid, this is Grid Home
