Suse10 10gR2 Laptop RAC

I recommend the following reading Linux 10g Laptop RAC.

I have just installed RAC 10gR2 on Suse10.

The document above guided me thru the steps.

Specific Suse10 :
- raw devices are configured by editing /etc/raw with values like raw1:loop1 and must be activated with rcraw start (+ chkconfig -a raw for persitence)

To take care :
- read point 8 to survive reboot...

Specific 10gR2 :
In 10gR2, MAXINSTANCES must not be specified by create controlfiles. In 10gR2, the controlfile can grow dynamically. Even if I created my controlfile with maxinstances=1, I can do alter database add logfile instance 'RAC2' ; alter database add logfile instance 'RAC2' ; alter database enable instance 'RAC2';, which is simply great! CREATE CONTROLFILE just belongs to the past!

I had to run vipca manually as root at the end of the root script of the crs installation. I also removed my existing oracle_homes and rebooted before installing database software again. The VIP interface must be configured in /etc/hosts and DOWN (ifconfig down eth0:2).

The doc written by Amit Poddar on Howad site is usefull. Enjoy rac'ing on your pocket desk calculator!
