RE: playing around with oracle 10.2, RAC with VMWare Server and Suse 10.1

first of all your ASM instances have to be set up clustered. You need to
access the diskgroups from all
To turn a single instance database into RAC you could use rconfig which
will do the job for you.
see chapter D in the os specific 10g Docs "Oracle Clusterware and Oracle Real Application Clusters Installation and Configuration Guide for ..."
If you want to do it on your own:
Create undo tablespaces for the other instances. Create redo log groups for the other threads. e.g.
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 4 SIZE 100M, GROUP 5 SIZE 100M, GROUP 6 SIZE 100M;
ALTER DATABASE ENABLE PUBLIC THREAD 2;
Parameters that should be set instance specific: instance_number,thread,instance_name,undo_tablespace. It is not neccessary to recreate your controlfile! Nevertherless the error you posted when trying this was related to ASM. Diskgroup was not mounted.
