EXERCISE 20-1. IF YOU HAVE REAL RAW DEVICES, SUBSTITUTE THEIR NAMES AC...

3. If using Windows, use the Notepad to create a file named INIT+ASM.ORA in

the ORACLE_HOME\database directory, with just these four lines:

instance_name='+asm'instance_type='asm'asm_diskstring='c:\app\oracle\raw*.disk'_asm_allow_only_raw_disks=false

If using Linux, use an editor such as vi to create a file named init+asm.ora in

the ORACLE_HOME/dbs directory with these five lines:

asm_diskstring='/u01/app/oracle/raw*.disk'memory_target=0

Note the use of the parameter _ASM_ALLOW_ONLY_RAW_DISKS. This is

a “hidden” parameter (use of which is not supported) that will allow ASM

to use files rather than raw devices for the purposes of this exercise. The last

parameter disables automatic memory management, which is necessary on

some Linux systems depending on how shared memory has been configured.
