**ORA-1078 ORA-1565 Errors while starting database with SPFILE on ASM**

I was getting following error’s while starting a database using spfile on ASM. Actually this was a cloned RAC environment.

SQL> create SPFILE='+ASM_GROUP/PORTALDB/spfileportaldb.ora' from pfile;
    File created.
    SQL> shut immediate;
    ORA-01109: database not open
    Database dismounted.
    ORACLE instance shut down.
    SQL> exit
    SQL> startup mount
    ORA-01078: failure in processing system parameters
    ORA-01565: error in identifying file '+ASM_GROUP/PORTALDB/spfileportaldb.ora'
    ORA-17503: ksfdopn:2 Failed to open file +ASM_GROUP/PORTALDB/spfileportaldb.ora
    ORA-01000: maximum open cursors exceeded

Error first states that it has failed to process the parameter. Second states that it has failed to identify the spfile and is unable to open. But I was able to open the database normally with pfile. Also the spfile was present in ASM diskgroup which I confirmed by listing DG contets on asmcmd prompt.

Problem here was that I had started the database with pfile from non-default location and pfile located in $ORACLE\_HOME/dbs had following entries

SPFILE='+ASM_GROUP/PORTALDB/spfileportaldb.ora'

In this case spfile too was created with same contents. Correct method is to specify the non-default pfile location in ‘create spfile’ syntax.

SQL> CREATE SPFILE='+ASM_GROUP/PORTALDB/spfileportaldb.ora' from pfile=\'/home/oracle/portaldb.ora\';
    
    File created.
    
    SQL> shut immediate;
    ORA-01109: database not open

# [Move SPFILE from ASM to File System][] #

The following is an example of how to move your SPFILE from ASM to your file system or vice versa

ASM to File System

In this case, we have our spfile in the +DATA diskgroup and we want to move it to the default location on our file system. The default location will be in our $ORACLE\_HOME/dbs directory. In order to accomplish this, we need to create a pfile from our existing spfile and then create the new spfile from this temporary pfile. Afterwords, we bounce the database instance for the change to take effect.

SQL> show parameter spfile
    
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    spfile                               string      +DATA/orcl/spfileorcl.ora
    
    SQL> create pfile='/tmp/orcl.pfile' from spfile;
    
    File created.
    
    SQL> create spfile='/u01/app/oracle/product/10.2.0/db_1/dbs/spfileorcl.ora'
    from pfile='/tmp/orcl.pfile';
    
    File created.
    
    SQL> startup force
    ORACLE instance started.
    ...
    Database mounted.
    Database opened.
    
    
    SQL> show parameter spfile
    
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    spfile                               string      /u01/app/oracle/product/10.2.0
                                                    /db_1/dbs/spfileorcl.ora

## Cleaning up the old ASM spfile ##

At this point you may want to clean up the old spfile within ASM. To do that, use the asmcmd utility to remove the file. The file system spfile will take precedence over the ASM spfile, but it’s not a bad idea to remove the old spfile in ASM.

$ . oraenv
    ORACLE_SID= [orcl] ? +ASM
    $ asmcmd
    ASMCMD> cd DATA/orcl
    ASMCMD> rm spfileorcl.ora
    ASMCMD> exit

## File System to ASM ##

The reverse procedure is similar. However, because Oracle will use the file system spfile first if it sees one, we need to remove or rename that file system spfile before bouncing the database instance.

SQL> show parameter spfile
    
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    spfile                               string      /u01/app/oracle/product/10.2.0
                                                    /db_1/dbs/spfileorcl.ora
    
    
    SQL> create pfile='/tmp/orcl.pfile' from spfile;
    
    File created.
    
    SQL> create spfile='+DATA/orcl/spfileorcl.ora'
    from pfile='/tmp/orcl.pfile';
    
    File created.
    
    $ cd $ORACLE_HOME/dbs
    $ mv spfileorcl.ora old_spfileorcl.ora
    
    
    SQL> startup force
    ORACLE instance started.
    ...
    Database mounted.
    Database opened.
    
    
    SQL> show parameter spfile
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    spfile                               string      +DATA/orcl/spfileorcl.ora

## Fixing an OMF spfile name ##

One common error you may run into is if you didn’t provide a full path to the spfile within your ASM diskgroup (i.e., you created the spfile as ‘+DATA’ instead of ‘+DATA/orcl/spfileorcl.ora’). If that happens, then Oracle is going to assign an Oracle Managed File (OMF) name to your spfile and all you need to do is create an alias for it using the asmcmd tool.

SQL> create pfile='/tmp/orcl.pfile' from spfile;
    File created.
    
    SQL> create spfile='+DATA'
    from pfile='/tmp/orcl.pfile';
    File created.
    
    $ cd $ORACLE_HOME/dbs
    $ mv spfileorcl.ora old_spfileorcl.ora
    
    SQL> startup force
    ORA-01078: failure in processing system parameters
    ORA-01565: error in identifying file '+DATA/orcl/spfileorcl.ora'
    ORA-17503: ksfdopn:2 Failed to open file +DATA/orcl/spfileorcl.ora
    ORA-15056: additional error message
    ORA-17503: ksfdopn:DGOpenFile05 Failed to open file +DATA/orcl/spfileorcl.ora
    ORA-17503: ksfdopn:2 Failed to open file +DATA/orcl/spfileorcl.ora
    ORA-15173: entry 'spfileorcl.ora' does not exist in directory 'orcl'
    ORA-06512: at line 4
    
    $ . oraenv
    ORACLE_SID= [orcl] ? +ASM
    $ asmcmd
    ASMCMD> cd DATA/orcl/
    ASMCMD> ls PARAMETERFILE
    spfile.277.756994081
    ASMCMD> mkalias +DATA/orcl/parameterfile/spfile.277.756994081
    +DATA/orcl/spfileorcl.ora
    ASMCMD> exit
    
    SQL> startup force
    ORACLE instance started.
    ...
    Database mounted.
    Database opened.
    
    
    SQL> show parameter spfile
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    spfile                               string      +DATA/orcl/spfileorcl.ora

This code was tested on an Oracle 10g Standard Edition database.

**ORA-01565: error in identifying file /dbs/spfile@.ora**

When we’re going to create pfile from spfile while spfile running on ASM instance, We can face the below errors,

SQL> create pfile=’/u01/inittest.ora’ from spfile;  
create pfile=’/u01/inittest.ora’ from spfile  
\*  
ERROR at line 1:  
ORA-01565: error in identifying file ‘?/dbs/spfile@.ora’  
ORA-27037: unable to obtain file status  
Linux Error: 2: No such file or directory  
Additional information: 3

Solution :

We need to give ASM path of SPFILE.

SQL> create pfile=’/u01/inittest.ora’ from spfile=’+DATA/dbasm/spfiledbasm.ora';

File created.
