command 'sqlplus system/manager' works fine. But in case connect system/manager as sysdba, it will tell me "ORA-01031: insufficient privileges" error.
[oracle@bej301441 ~]$ sqlplus system/manager as sysdba

ERROR:
ORA-01031: insufficient privileges
Solution
This is not the sqlplus which under $RDBMS_ORACLE_HOME.We need switch ORACLE_HOME to realoracle账号 DB HOME,and use sqlplus which in DB HOME to connect.
[oracle@bej301441 ~]$ which sqlplus
/u01/oracle/mc3yd213/apps/tech_st/10.1.2/bin/sqlplus
cd to DB home,and run env file, this will set required env parameters.
[oracle@bej301441 11.1.0]$cd /u01/oracle/mc3yd213/db/tech_st/11.1.0
[oracle@bej301441 11.1.0]$ . ./mc3yd213_bej301441.env
Now you can check $ORACLE_HOME, and sqlplus directory
[oracle@bej301441 11.1.0]$ echo $ORACLE_HOME
/u01/oracle/mc3yd213/db/tech_st/11.1.0
[oracle@bej301441 11.1.0]$ which sqlplus
/u01/oracle/mc3yd213/db/tech_st/11.1.0/bin/sqlplus
[oracle@bej301441 11.1.0]$ sqlplus system/manager as sysdba
