在设置 sec_case_sensitive_logon = true之后，怎么为database中的user启用大小写混合的密码

解决方案：

The supplied password verify function in the file $ORACLE_HOME/rdbms/admin/utlpwdmg.sql  does not  enforce that the password has both upper and lower case characters. To achieve this, it is possible to modify the function as follows:

cp utlpwdmg.sql utlpwdmg_modif.sql

vi utlpwdmg_modif.sql

Add the following code:

-- Check the password uses mixed case

if upper(password) = password or lower(password) = password then

raise_application_error(-20012, 'Password is not mixed case');

end if;

Then run the script utlpwdmg_modif.sql as user SYS and to test:

create profile test_profile limit password_verify_function verify_function_11g;
 create user test identified by test profile test_profile;

 connect test/test

 SQL> alter user test identified by "kachel1#" replace test;
 alter user test identified by "kachel1#" replace test
 *
 ERROR at line 1:
 ORA-28003: password verification for the specified password failed
 ORA-20012: Password is not mixed case

 SQL> alter user test identified by "KACHEL1#" replace test;
 alter user test identified by "KACHEL1#" replace test
 *
 ERROR at line 1:
 ORA-28003: password verification for the specified password failed
 ORA-20012: Password is not mixed case

 SQL> alter user test identified by "Kachel1#" replace test;

 User altered.
