创建用户时的密码校验问题（r2第34天)

今天需要在测试环境中做一些性能测试，为了不影响原有的数据，准备创建一个临时的schema。但是创建的时候报了如下的错误。 SQL> create user mig_perf identified by mig_perf; create user mig_perf identified by mig_perf * ERROR at line 1: ORA-28003: password verification for the specified password failed ORA-20002: Password same as or similar to user 第一感觉就是开启了密码的校验，11g里面有一个新特性的关于密码的大小写敏感的，会不会有关联呢。似乎有些牵强，但是目前是false选项，表示不对大小写敏感。 SQL> show parameter sen NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ sec_case_sensitive_logon boolean FALSE 如果还有问题，就需要从profie的角度入手了，比如登录密码超过10次，账户就会锁定，这些都是在profile里面配置的。 来看看能得到什么信息。 select *from dba_profiles order by profile; SQL> / PROFILE RESOURCE_NAME RESOURCE LIMIT ------------------------------ -------------------------------- -------- ---------------------------------------- DBAMON_PF1 COMPOSITE_LIMIT KERNEL UNLIMITED DBAMON_PF1 SESSIONS_PER_USER KERNEL 10 DBAMON_PF1 CPU_PER_SESSION KERNEL UNLIMITED DBAMON_PF1 CPU_PER_CALL KERNEL UNLIMITED DBAMON_PF1 LOGICAL_READS_PER_SESSION KERNEL UNLIMITED DBAMON_PF1 LOGICAL_READS_PER_CALL KERNEL UNLIMITED DBAMON_PF1 IDLE_TIME KERNEL UNLIMITED DBAMON_PF1 CONNECT_TIME KERNEL UNLIMITED DBAMON_PF1 PRIVATE_SGA KERNEL DEFAULT DBAMON_PF1 FAILED_LOGIN_ATTEMPTS PASSWORD 10 DBAMON_PF1 PASSWORD_LIFE_TIME PASSWORD UNLIMITED DBAMON_PF1 PASSWORD_REUSE_TIME PASSWORD UNLIMITED DBAMON_PF1 PASSWORD_REUSE_MAX PASSWORD UNLIMITED DBAMON_PF1 PASSWORD_VERIFY_FUNCTION PASSWORD VERIFY_FUNCTION DBAMON_PF1 PASSWORD_LOCK_TIME PASSWORD .0106 DBAMON_PF1 PASSWORD_GRACE_TIME PASSWORD UNLIMITED DEFAULT COMPOSITE_LIMIT KERNEL UNLIMITED DEFAULT SESSIONS_PER_USER KERNEL UNLIMITED DEFAULT CPU_PER_SESSION KERNEL UNLIMITED DEFAULT CPU_PER_CALL KERNEL UNLIMITED DEFAULT LOGICAL_READS_PER_SESSION KERNEL UNLIMITED DEFAULT LOGICAL_READS_PER_CALL KERNEL UNLIMITED DEFAULT IDLE_TIME KERNEL UNLIMITED DEFAULT CONNECT_TIME KERNEL UNLIMITED DEFAULT PRIVATE_SGA KERNEL UNLIMITED DEFAULT FAILED_LOGIN_ATTEMPTS PASSWORD 10 DEFAULT PASSWORD_LIFE_TIME PASSWORD 180 DEFAULT PASSWORD_REUSE_TIME PASSWORD UNLIMITED DEFAULT PASSWORD_REUSE_MAX PASSWORD UNLIMITED DEFAULT PASSWORD_VERIFY_FUNCTION PASSWORD VERIFY_FUNCTION_11G DEFAULT PASSWORD_LOCK_TIME PASSWORD 1 DEFAULT PASSWORD_GRACE_TIME PASSWORD 7 我创建的新用户，没有指定profile，所以会是默认的default profile，对应的"PASSWORD_VERIFY_FUNCTION" 有一些差别。 看来是对于密码安全的加强，来看看相关的简单测试，看看密码验证还都做了那些校验。 SQL> create user mig_perf identified by mig_perf1; create user mig_perf identified by mig_perf1 * ERROR at line 1: ORA-28003: password verification for the specified password failed ORA-20005: Password same as or similar to user name SQL> create user mig_perf identified by abc; create user mig_perf identified by abc * ERROR at line 1: ORA-28003: password verification for the specified password failed ORA-20001: Password length less than 8 SQL> create user mig_perf identified by abcabc12; User created. SQL> drop user mig_perf; User dropped. 当然了“PASSWORD VERIFY_FUNCTION_11G”其实是一个function来实现的。具体的细节可以在$ORACLE_HOME/rdbms/admin/utlpwdmg.sql中查看。 > ls -lrt utlpwd* -rw-r--r-- 1 oraccbs1 dba 11555 Aug 13 2006 utlpwdmg.sql -- This script sets the default password resource parameters -- This script needs to be run to enable the password features. -- However the default resource parameters can be changed based -- on the need. -- A default password complexity function is also provided. -- This function makes the minimum complexity checks like -- the minimum length of the password, password not same as the -- username, etc. The user may enhance this function according to -- the need. -- This function must be created in SYS schema. -- connect sys/<password> as sysdba before running the script CREATE OR REPLACE FUNCTION verify_function_11G (username varchar2, password varchar2, old_password varchar2) RETURN boolean IS n boolean; m integer; differ integer; isdigit boolean; ischar boolean; ispunct boolean; db_name varchar2(40); digitarray varchar2(20); punctarray varchar2(25); chararray varchar2(52); i_char varchar2(10); simple_password varchar2(10); reverse_user varchar2(32); BEGIN digitarray:= '0123456789'; chararray:= 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; 。。。。 而且在11g的数据字典里也有所体现，可以看到如下的用户密码是10g,11g的 在dba_users中有一列 password_version ****************************************************************************************************** * General Details * ****************************************************************************************************** USERNAME Default Tablespace CREATED PROFILE PASSWORD_V ------------------------- -------------------- --------- ---------- ---------- MIG_PERF DATAS01 31-MAR-14 DEFAULT 10G 11G 一些相关的链接如下： How To Enforce Mixed Case Passwords When sec_case_sensitive_logon = true?
