ORA-01031: insufficient privileges问题解决办法

在操作系统本地在oracle用户下使用sqlplus / as sysdba连接sqlplus的时候提示ORA-01031: insufficient privileges

查看操作系统版本信息

[oracle@OracleBak admin]$ lsb_release -aLSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarchDistributor ID: CentOSDescription:    CentOS release 6.6 (Final)Release:        6.6Codename:       Final

正常本地登陆的时候应该不需要授权的，检查sqlnet.ora文件，文件路径为$ORACLE_HOME/network/admin/sqlnet.ora,

[oracle@OracleBak admin]$ cat sqlnet.ora # sqlnet.ora Network Configuration File: /opt/ora11/product/11.2/network/admin/sqlnet.ora# Generated by Oracle configuration tools.SQLNET.AUTHENTICATION_SERVICES= (NTS)NAMES.DIRECTORY_PATH= (TNSNAMES,EZCONNECT)

检查监听和tnsping均正常，查阅资料后发现sqlnet.ora中的SQLNET.AUTHENTICATION_SERVICES

1、在windows下，SQLNET.AUTHENTICATION_SERVICES必须设置为NTS才能使用OS认证；
不设置或者设置为其他任何值都不能使用OS认证。

2、在linux下，在SQLNET.AUTHENTICATION_SERVICES的值设置为ALL，或者不设置的情况下，OS验证才能成功；

将此参数修改为ALL后即可使用sqlplus / as sysdba;直接登陆了，可是使用sqlplus sys/oracle@orcl as sysdba;登陆的时候提示ORA-12641: Authentication service failed to initialize，将sqlnet.ora中的

SQLNET.AUTHENTICATION_SERVICES= (ALL)

这一行去掉之后再使用用户名和密码登陆可以正常登陆了
