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