Solution of LRM-00109 error in Oracle Database.

Article explains solution of LRM-00109 error while starting database.

When user got following errors to gather it is may be due to some mismatch with server parameter file (spfile) and parameter file (init.ora). Generally these errors are occurring due to not exist of pfile or spfile on system. May be oracle doesn't find out parameter file in default location. Or may be file there but contents of file is wipe off. There are so many reasons for getting ORA-01078 with LRM-00109 errors to gather. If you get only ORA-01078 then it is indication of wrong parameter configuration. But when you get both errors simultaneously is indicating problem of parameter file/server parameter file existence. In this article we can see how error will be generating and how it gets resolved. 

 SQL> conn /as sysdba

Connected to an idle instance.

SQL> startup 

ORA-01078: failure in processing system parameters 

LRM-00109: could not open parameter file 'D:\ORACLE\ORA92\DATABASE\INITGPT.ORA' 

 Reason: Server parameter file or parameter file doesn't available::

Some times error ORA-01078 is coming with LRM-00109. It is due to either spfile or init.ora doesn't available in required path. If database is running with spfile and there is no init.ora available in system. If Oracle dba execute following command in SQL*Plus for creating spfile.ora (which already there in system but init.ora doesn't in system). 

 SQL>create spfile from pfile;

*

ERROR at line 1:

ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file 'D:\ORACLE\ORA92\DATABASE\INITGPT2.ORA'

System will generate error for creating spfile because required init.ora doesn't available. Means you will get error. But your command "create spfile from pfile" will be generating new empty spfile and it will be overwriting existing spfile. Means your current spfile has been washed and becoming empty. After getting this error if you are trying to restart your database then you will get actual following error due to spfile file is empty. 

 SQL> startup

ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file 'D:\ORACLE\ORA92\DATABASE\INITGPT2.ORA'

 How to resolve ORA-01078 with LRM-00109 error? 

 For resolving this error, you should need to replace init.ora or spfile if you have backup of same files. If you don't have backup then go to alert.log and copy all parameters in one file and save as "init.ora". Modify same init.ora with some parameters which need single quotation mark " ' " like background_dump_dest,controlfiles,db_name etc. Connect as sysdba in SQL*Plus and execute command "create spfile from pfile". This command will generate again your server parameter file (spfile) in system which needs to be starting database.
