When starting a database, which is in version 12c, aperece the following error;
SQL> startup ORA-01078: failure in processing system parameters LRM-00109: could not open parameter file ‘C:\ORACLE\DB_1\DATABASE\INITSITO.ORA’
It seems that missed init.ora. Fortunately or rather a rule I usually have contfolfile autobackup, so this case is simple bastantante solve the problem. We must connect to RMAN and execute the following commands.
rman> STARTUP NOMOUNT rman> RESTORE SPFILE FROM AUTOBACKUP
