This problem occurs after the database is installed today. I searched the internet and found many posts to solve this problem,
SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: cocould not open parameter file '/u01/app/oracle/product/10.2.0/db_1/dbs/initora10g. ora'
Directly perform the following operations:
Cp/u01/app/oracle/admin/orcl/pfile/init. ora.823201112436/u01/app/oracle/product/10.2.0/db_1/dbs/initora10g. ora
In addition, pay attention to the following issues,
[Root @ localhost dbs] # ls-l

Confirm the permission of this file. If the permission is different from the permission of the current file, modify the following:
[Root @ localhost dbs] # chown oracle: oinstall initora10g. ora
After the above operations, there should be no problem
