ORA-01031: insufficient privileges 问题解决笔记

关于ORA-01031: insufficient privileges 问题解决笔记 A） File $Oracle_HOME/network/admin/sqlnet.ora
这个是涉及oracle 是os 认证，还是密码文件认证$ORACLE_HOME/network/admin/sqlnet.ora中的AUTHENTICATION_SERVICES参数：
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；此外还有这个参数
spfile中的REMOTE_LOGIN_PASSWORDFILE参数：
1、值为exclusive时，远程能作为sysdba身份登录
2、值为none时，以sysdba身份无法登录B） File $ORACLE_HOME/rdbms/lib/config.c（or config.s）
C） The output of command "id"
oracle 用户拥有正确辅组，如果没有dba 组则也无法进行操作系统认证登入数据库
一般以上2个是常见的原因，如果查证后还是有问题可以尝试以下方法：
D） A trace file obtained with the following commands:Linux:
strace -o /tmp/strace_sysdba.output -cfT sqlplus / as sysdbaAIX, Solaris:
truss -fea -o /tmp/truss_sysdba.output sqlplus / as sysdba
HP-UX:
tusc -afpo /tmp/tusc_sysdba.output -aef sqlplus / as sysdbaFor WindowsA） File %ORACLE_HOME%/network/admin/sqlnet.ora
B） The output of the commands "echo %username% and "NET LOCALGROUP ORA_DBA"
C） A pair of client/server SQL*Net traces obtained while reproducing the problem as per Note 395525.1 and Note 374116.1以下是一个测试案例：【去掉oracle 的 dba 组】[oracle@vmrac1 ~]$ strace -o /tmp/strace_sysdba.output -cfT sqlplus / as sysdbaSQL*Plus: Release 11.2.0.2.0 Production on Tue Aug 26 16:04:46 2014Copyright （c） 1982, 2010, Oracle.
