How mounting two or more instance + OFA HowTo + others problems

[Quoted] 1)I'm having two databases ORCL, TEST. I'm putting the neccessary entry in tnsnames.ora and listener.ora for the two databases. In oratab file, i'm putting a line for eache DB with "Y". The problem: I can connect only to one of my DB, for the second I got error message ora-01033. What is the problem please.

2) In the following a part of my initORCL.ora file.

   for LOGFILE (as you can see below, this is also the case for controlfiles), I'm dispatching redolgfiles on three physically seperated drivers.
My question is: can I do the same thing for DATAFILE? if Yes where I can? Juste before AUTOEXTEND ON? What about temp, tools, users, index... files can I dispatched them also as LOGFILE? dbassit, and OFA docs do not show what to do exactly.

CREATE DATABASE ORCL
controlfile reuse

LOGFILE '/u01/oradata/ORCL/redolog_1.rdo' size 50M REUSE,


        '/u02/oradata/ORCL/redolog_2.rdo' size 50M REUSE,


        '/u03/oradata/ORCL/redolog_3.rdo' size 50M REUSE


                MAXLOGMEMBERS 3
                MAXLOGHISTORY 1
DATAFILE '/u01/oradata/ORCL/system01.dbf' SIZE 300M REUSE
                AUTOEXTEND ON
                MAXDATAFILES 254
                MAXINSTANCES 1
                CHARACTER SET WE8ISO8859P1
                NATIONAL CHARACTER SET WE8ISO8859P1;
