SQL> conn / as sysdba
ERROR:
ORA-01031: insufficient privileges

解决方法：

$id oracle
uid=500(oracle) gid=500(oinstall) groups=500(oinstall)

少了一个DBA组！

#usermod -G dba oracle

# id oracle
uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)

通常还要关注以下这个配置：

$cat $ORACLE_HOME/network/admin/sqlnet.ora
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
