OFA changes for Oracle 10gR2

The most notable change to the Oracle Flexible Architecture for Oracle 10g is 
the ORACLE_HOME directory name. Previously OFA recommendation was:

   /u01/app/oracle/product/9.2.0

with Oracle Database 10g is has been changed to:

   /u01/app/oracle/product/10.2.0/type[_n]

where 'type' is the type of ORACLE_HOME:

   db -- database Oracle Home
   client -- client Oracle Home

and '_n' is the counter designator so that you can have multiple installations 
of the same Oracle software release in a common Oracle base directory, for 
example:

   /u01/app/oracle/product/10.2.0/db_1
   /u01/app/oracle/product/10.2.0/db_2

I am a big supporter of OFA and I recommend that you adopt these changes as 
soon as possible.
