I have a problem about install a new database on asm in RAC

Question

i installed crs and oracle db,next step i want to create a db on asm using dbca.rsp
following info is some options in dbca.rsp,but i do not know how to edit my template file(here is mydb.dbc),let the datafile path point to ASM disk
if it will create ASM diskgroup ORADG,it will also create path +ORADG/oradata directory automatically during dbca's create process?
and can i put flash_recovery_are on asm?

Hi,
wouldn't create database using dbca is more easy and error-less?
Template file format is basically like xml format. If you have created Diskgroup then you can use
$ dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName mydb -sid mydb1,mydb2 -SysPassword Myss123456 -SystemPassword Myss123456 -emConfiguration NONE -storageType ASM -asmSysPassword Myss123456 -diskGroupName ORADG
Cheers
