ORA-01078: failure in processing system parameters

Today, I got a issue during my experience
 ORA-01078: Failure in processing system parameters,
 LRM-00109: could not open parameter file '/app/oracle/product/11.2.0/db_1/dbs/init.ora
 Its first time I'm on this issue
 So, i realized that Failure caused during processing of INIT.ORA parameters during system startup.

My action was like the following and it had fixed, May be we can see easy/different way on the internet,However let me fix it :) 

[oracle@localhost ]$ sqlplus as sysdba 

SQL>startup 

ORA-01078: failure in processing system parameters LRM-00109: could not open parameter file '/app/oracle/product/11.2.0/db_1/dbs/init.ora' 

SQL> exit

Disconnected

Open database nomount mode by pfile

SQL> startup nomount pfile=/app/oracle/admin/orcl/pfile/init.ora

ORACLE instance started.

Create pfile again

SQL> create spfile from pfile

2 ;

create spfile from pfile

*

ERROR at line 1:

ORA-01078: failure in processing systemparameters

LRM-00109: could not open parameter file

'/app/oracle/product/11.2.0/db_1/dbs/init.ora'

 Create like that

SQL> create spfile from pfile='/app/oracle/admin/orcl/pfile/init.ora';

File created.

NOW create pfile 

SQL> create pfile from spfile;

File created.

SQL> exit

I got init.ora

 [oracle@localhost pfile]$ ls

init.ora

 [oracle@localhost pfile]$sqlplus

Enter user-name: sys as sysdba

Enter password:

I thought i resolved my issue but after this select 

SQL> select name from v$database;

select name from v$database

ERROR at line 1:

Close database

SQL> shutdown immediate;

ORA-01507: database not mounted

ORACLE instance shut down.

Open it should work i guess :)

SQL> startup
