ORA-01031: insufficient privileges 错误解决

今天用em的方式远程登入Linux AS3 上的Oracle 10G，始终无法用sys以sysdba，system以sysoper的身份登入，只能以normal的身份登入。

直接telnet到主机上检查，发现也无法以sysdba的身份登入。

[oracle@guohuias3 dbs]$ sqlplus sys/kelantas@orcl as sysdba

ERROR:
ORA-01031: insufficient privileges

Enter user-name:

以internal的方式登入

[oracle@guohuias3 oracle]$ sqlplus /nolog

SQL> connect /as sysdba
Connected.
SQL> show parameter password;

NAME TYPE VALUE

SQL> grant sysdba to sys;
grant sysdba to sys
*
ERROR at line 1:
ORA-01994: GRANT failed: password file missing or disabled

SQL> select * from v$pwfile_users;

no rows selected

发现没有password文件；

检查password文件是否正确

[oracle@guohuias3 dbs]$ cd $ORACLE_HOME/dbs
[oracle@guohuias3 dbs]$ ls -l orapw*
-rw-r----- 1 oracle oinstall 5120 Jul 9 2010 orapwAUXY.pwd
-rw-r----- 1 oracle oinstall 2560 Feb 18 20:26 orapworcl

检查当前 $ORACLE_SID=ORCL

发现password文件的orcl是小写的，把它改正过来

[oracle@guohuias3 dbs]$ mv orapworcl orapwORCL
并再次查询相关视图：
SQL> select * from v$pwfile_users;

USERNAME SYSDB SYSOP
------------------------------ ----- -----
SYS TRUE TRUE

可以看到有对应的password文件了。

现在再次登入

[oracle@guohuias3 dbs]$ sqlplus sys/kelantas@orcl as sysdba
