Recover database Issue after missing spfile or pfile

In order to discover pfile or spfile I have discussed in The different ways to discover initialization parameter (spfile or pfile)

Now you may have the scenario that you yet not discovered your spfile or pfile then the remaining option is to create a new pfile. Suppose that you create your spfile like this.

-bash-3.00$ vi /oradata2/1.pfile
undo_tablespace=UNDOTBS1
undo_management=AUTO
compatible=10.2.0.1.0
db_name=arjudba
sga_target=400M

That is without control_files parameter inside it. It is ok if you don't have any controlfile and you want to create a new one. If you don't give any location inside pfile then oracle will create controlfile in the location of $ORACLE_HOME/dbs/cntrlarjudba.dbf.

However if you specify control_files parameter inside pfile then oracle will attempt to create controlfile in the specified location. Like if you create pfile as
-bash-3.00$ vi /oradata2/1.pfile
undo_tablespace=UNDOTBS1
undo_management=AUTO
compatible=10.2.0.1.0
db_name=arjudba
control_files='/oradata2/arjudba/arjudba/control01.ctl','/oradata2/arjudba/arjud
ba/control02.ctl'
sga_target=400M

then create controlfile statement will create controlfile in the location of /oradata2/arjudba/arjudba/control01.ctl, and /oradata2/arjudba/arjudba/control02.ctl

If you don't give any location of control_file parameter inside pfile then further startup will fails with ORA-00205
Like,

SQL> startup
ORACLE instance started.
