(RAC) Software 32-bit on CentOS EL 4 Update 5 (ASM_HOME)

It is always recommended to install RAC bineries in atleast two different HOMEs one for ASM and another for DB homes.
Lets start Installing RAC bineries for ASM_HOME.

set ORACLE_BASE to /u01/app/asm for this installation.

Start the runInstaller command as oracle user from any one node When OUI displays the Welcome page, click Next

[oracle@node1-pub ~]$ export ORACLE_BASE=/u01/app/asm
[oracle@node1-pub ~]$ 11g_database/database/runInstaller
