Connected to an idle instance.

SQL> startup mount;
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/oracle/product/'



could not open parameter file “string”

This LRM-00109 errors are related with the missing of parameter file (pfile or spfile)


To solve this error, you can check and fix the PFILE or SPFILE NAME. 


I have changed pfile name with initCLONE.ora and it is started as follows.

SQL> startup mount;
ORACLE instance started.

Total System Global Area 2.1379E+10 bytes
Fixed Size 2230912 bytes
Variable Size 1.0469E+10 bytes
Database Buffers 1.0872E+10 bytes
Redo Buffers 36106240 bytes
Database mounted.



Sometimes If you set wrong ORACLE_SID, you may get this error. So check your ORACLE_SID with the following command.




Or IF Pfile or spfile don’t exist, then you can create it manually or you can restore spfile from backup.
