Oracle 9i rac spfile in raw

Question

We have a 9i Oracle RAC which uses init.ora files for two nodes instead of the shared spfile. The spfile is created in a shared raw device but it is not being used.
I would like to fix that. I have two possible methods I would like to confirm
Method 1:
1. Can I remove the spfile from the shared disk? It is a raw device... I have never worked with raw devices before for spfiles. Doing an "rm spfile" would work although it points to a raw?
2. Create a shared spfile that points to a raw from any of the init.ora files.
Method 2:
Or would it be better to do that in a single step:
create spfile '/oracle/oradata/spfile.ora' from pfile '/home/oracle/init1.ora';
where /oracle/oradata/spfile.ora points to a raw device then point each init.ora file to the shared spfile location?

Answer 1

Dear Chandra Pabba,
I Successfully created shared spfile but load balance has been failed ...and all connections are being made to one instance only.....

Now, I created a spfile on shared storedge by using node1
sql> create spfile='/dev/vx/rdsk/oradg1/itpo_raw_spfile_10m' from
pfile='/orahome/pfile_03092009.ora';
it successfulya created
After it I escaleted the spfile from dbs to raw partition
making entry into inititpo1.ora and inititpo2.ora of each node's dbs
folder
SPFILE=/dev/vx/rdsk/oradg1/itpo_raw_spfile_10m
Now the probleme is user are connecting with only one instance........
when i checked
sql> select username,inst_id from gv$session;
it lists only connection on only one node itpo1....
If any have idea about this then suggestion will be greatly
appreciated....
Thanks in Advanced
