oracle 密码文件文件
密码文件作用:
密码文件用于dba用户的登录认证。
dba用户:具备sysdba和sysoper权限的用户,即oracle的sys和system用户。
本地登录:
1)操作系统认证:
[oracle@localhost ~]$ sqlplus "/as sysdba"
[oracle@localhost ~]$ sqlplus / as sysdba
[oracle@localhost ~]$ sqlplus sys/tiger as sysdba
2)密码文件认证:
[oracle@localhost ~]$ sqlplus sys/tiger@rezin as sysdba
远程密码文件登录:
[oracle@localhost ~]$ sqlplus sys/tiger@192.168.96.141:1521/orcl as sysdba
密码文件位置:
linux/unix:[oracle@localhost ~]$ ls $ORACLE_HOME/dbs/orapw$ORACLE_SID
/u01/oracle/10g/dbs/orapworcl
/u01/oracle/10g/dbs/orapwrezin
windows:$ORACLE_HOME/oradate/orapw$ORACLE_SID
密码文件查找顺序:
1)opapw<sid>
2)orapw
以上两个都查找不到,验证失败。
密码文件认证还是OS认证:
1)参数文件:remote_login_passwordfile=none|exclusive|shared
none:不使用密码文件认证
exclusive:使用密码文件认证,自己独占使用(默认)
shared:使用密码文件认证,不同实例dba用户可以共享密码文件(asm下必须使用)
2)$ORACLE_HOME/network/admin/sqlnet.ora文件下:
SQLNET.AUTHENTICATION_SERVICES =none|all|nts(linux下默认没有设置)
none:关闭OS认证,只能密码文件认证
all:linux平台关闭本机密码文件认证,采用操作系统认证,但是远程(异机)可以密码文件认证
nts:windows下使用(桶linux下all)
练习:
1)配置:remote_login_passwordfile=exclusive
SQLNET.AUTHENTICATION_SERVICES =none
结果:可以密码文件认证(本地/远超),不可以操作系统认证
[oracle@localhost ~]$ sqlplus sys/tiger as sysdba(本地密码文件登录)
[oracle@localhost ~]$ sqlplus sys/tiger@rezin as sysdba(本地密码文件登录)

密码文件管理:
密码文件建立:orapwd命令用法(不建议使用)
[oracle@localhost ~]$ orapwd
Usage: orapwd file=<fname> password=<password> entries=<users> force=<y/n>
where
file - name of password file (mand), -->创建密码文件名字:orapw<sid>
password - password for SYS (mand), -->sys用户密码
entries - maximum number of distinct DBA and -->可以有多少个sysdba和sysoper用户可以放到密码文件里边去(采用二进制方式,即输入1表示最少存放4个,去除重复的)
force - whether to overwrite existing file (opt), -->oracle 10g后新加的参数,用法:force=n或force=y,表示密码文件存在是否覆盖,10g之前只能删除原有的密码文件,再创建。
OPERs (opt),
There are no spaces around the equal-to (=) character.
例如:[oracle@localhost ~]$orapwd file=orapworcl password=rezin entries=1 force=y
密码文件修改:例如 修改sys用户密码或授予sysdba、sysoper权限
orapwd重建密码文件:不建议使用,可能会让其他sys用户不能登录
alter user sys identified by <new password>
grant sysdba|sysoper to <user>;
revoke sysdba|sysoper from <user>
查看密码文件内容:strings指令查看二进制文件内容。
[oracle@localhost dbs]$ strings orapworcl
]\[Z
ORACLE Remote Password file
INTERNAL
9D9FF9FDAFB17385
E6BAA2164C375C09
sysdba和sysoper具体区别:查看官方文档
通过system_privilege_map视图查看系统权限:
SQL> select * from system_privilege_map
2 where name like '%SYS%';
PRIVILEGE NAME PROPERTY
---------- ---------------------------------------- ----------------------------------------------------------
-3 ALTER SYSTEM 0
-4 AUDIT SYSTEM 0
-83 SYSDBA 0
-84 SYSOPER 0
查看用户系统权限通过密码文件视图v$pwfile_user查看:
SQL> select * from v$pwfile_users;
USERNAME SYSDB SYSOP
------------------------------ ----- -----
SYS TRUE TRUE
通过以上查询可以知道,sys用户登录方式既可以通过as sysdba登录schema显示‘SYS’,也可以通过as sysoper登录schema显示‘PUBLIC’。
LAST验证:需要配合参数文件知识练习
1、按照组合:
1)remote_login_passwordfile=none sqlnet.authentication_services=none
2)remote_login_passwordfile=exclusive sqlnet.authentication_services=none
3)remote_login_passwordfile=none sqlnet.authentication_services=all
如果是win,请你把all改为nts
4)remote_login_passwordfile=exclusive sqlnet.authentication_services=all
分别测试:
本机:sqlplus / as sysdba
sqlplus sys/<pswd> as sysdba
sqlplus sys/<pswd>@<sid> as sysdba
远程:sqlplus sys/<pswd>@<sid> as sysdba
sqlplus sys/<pswd>@ip:port/<sid> as sysdba
测试哪些组合可以登录成功,哪些不能登录成功。
总结出如果关闭OS验证;如何关闭密码文件验证;如何关闭本地密码文件验证;如何关闭远程密码文件验证。
2、修改remote_login_passwordfile=shated然后使用alter user sys identified by <pswd>;修改密码,测试能否修改成功。
不允许修改
3、如果sys密码丢失或不对,你如何做?
alter user sys identified by tiger;修改密码
4、sysdba、sysoper区别在哪,普通用户如何使用密码文件已sysdba或sysoper登录。
答案:
1)remote_login_passwordfile=none sqlnet.authentication_services=none
关闭密码文件认证,关闭OS认证。
