convert oracle RDBMS to ASM RDBMS step by step.

OS details of Both node:-

Linux DB11G.example.com 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

Red Hat Enterprise Linux Server release 5.4 (Tikanga)

DB name:

SQL> select name from v$database;

NAME
---------
DB11G

Node1 hostname:

DB11G.example.com

Node2 hostname:

ASM_DB.example.com

step1)

create pfile for spfile for duplicate database.

SQL> create pfile from spfile;

File created.

step2)
make the following changes in pfile.

I have already created 2 ASM diskgroups DATA and FRA.

*.control_files=(+DATA, +FRA)
*.db_recovery_file_dest=+FRA
*.db_recovery_file_dest_size=2147483648
*.db_create_file_dest=+DATA
*.db_create_online_log_dest_1=+FRA
*.db_create_online_log_dest_2=+DATA -- optional if you want another online redo logs dest.

move password file and pfile to target location.

[oracle@DB11G dbs]$ scp initDB11G.ora oracle@ASM_DB:/u01/app/oracle/product/11.2.0/db_1/dbs/
oracle@ASM_DB's password:
initDB11G.ora 100% 997 1.0KB/s 00:00

[oracle@DB11G dbs]$ scp orapwDB11G oracle@ASM_DB:/u01/app/oracle/product/11.2.0/db_1/dbs/
oracle@ASM_DB's password:
orapwDB11G 100% 1536 1.5KB/s 00:00
[oracle@DB11G dbs]$

step3)

Create directory structure, same as DB11Gory database.         ---------optional

$ mkdir -p /u01/app/oracle/oradata/DB11G
$ mkdir -p /u01/app/oracle/fast_recovery_area/DB11G
$ mkdir -p /u01/app/oracle/admin/DB11G/adump

step4)
tnsname.ora  on primary database server(DB11G.example.com)

# Generated by Oracle configuration tools.

DB11G =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = DB11G.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = DB11G)
    )
  )
DB11G_tar =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ASM_DB.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = DB11G)
    (UR = A)
    )
  )

step5)

Start duplicate (tareget) database in nomount.

[oracle@ASM_DB admin]$ export $ORACLE_SID=DB11G
[oracle@ASM_DB admin]$ echo $ORACLE_SID
DB11G
[oracle@ASM_DB admin]$ sqlplus
