convert oracle ASM database instance to normal database instance 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:
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> select name from v$database;
NAME
---------
DB11G
Node1 hostname:
ASM.example.com
Node2 hostname:
DB11g.example.com
step1)
create pfile for spfile for duplicate database.
SQL> create pfile from spfile;
File created.
step2)
Create directory structure, same as DB11Gory database.
$ mkdir -p /u01/app/oracle/oradata/DB11G
$ mkdir -p /u01/app/oracle/fast_recovery_area/DB11G
$ mkdir -p /u01/app/oracle/admin/DB11G/adump
step3)
Make the following changes in pfile.

Replace the ASM disk with file system path.
*.audit_file_dest='/u01/app/oracle/admin/DB11G/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.control_files='/u01/app/oracle/oradata/DB11G/control01.CTL','/u01/app/oracle/fast_recovery_area/DB11G/control02.CTL'
*.db_block_size=8192
*.db_create_file_dest='/u01/app/oracle/oradata'
*.db_create_online_log_dest_1='/u01/app/oracle/fast_recovery_area'
*.db_domain=''
*.db_name='DB11G'
*.diagnostic_dest='/u01/app/oracle'

Step4)
Move password file and pfile to target location.
[oracle@ASM dbs]$ scp initDB11G.ora oracle@clone:/u01/app/oracle/product/11.2.0/db_1/dbs/
oracle@clone's password:
initDB11G.ora 100% 997 1.0KB/s 00:00
Monday, February 20, 2017
[oracle@ASM dbs]$ scp orapwDB11G oracle@clone:/u01/app/oracle/product/11.2.0/db_1/dbs/
oracle@clone's password:
orapwDB11G 100% 1536 1.5KB/s 00:00
[oracle@ASM dbs]$

Step5)
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 = clone.example.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DB11G)
(UR = A)
)
)

Step6)
Start duplicate (tareget) database in nomount.
[oracle@DB11G admin]$ export $ORACLE_SID=DB11G
[oracle@DB11G admin]$ echo $ORACLE_SID
DB11G
[oracle@DB11G admin]$ sqlplus
