Install oracle12c and start the error report ORA-01078: failure in processing system parameters

ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file'/ u01qapplash oracle.product12.2.0anddbhomeowners 1anddbsandinitdb12c.ora'
Because in the parameter file, export ORACLE_SID=db12c
But when dbca built the database, the database was named kobe, so the parameter file could not be found.
Method: change to kobe
Export ORACLE_SID=kobe
Take effect again
Recommendation: ORACLE_SID should be the same as the database created
