1.更改sysadmin密码
1.1 如果有shell密码，可通过CPASS工具进行更改：
FNDCPASS apps/appspwd 0 Y system/manager USER SYSADMIN newspassword

演示：
-bash-3.2$ FNDCPASS apps/apps 0 Y system/manager USER SYSADMIN welcome1
Log filename : L5818900.log

Report filename : O5818900.out

1.2 如果有apps密码，可通过fnd_user_pkg存储过程进行更改：
declare
l_flag boolean;
begin
l_flag = fnd_user_pkg.change_password('sysadmin','newpassword');
end;

演示：
SQL> set serveroutput on
SQL> DECLARE
2 l_flag BOOLEAN;
3 BEGIN
4 l_flag := fnd_user_pkg.changepassword ('sysadmin', 'welcome2');
5 DBMS_OUTPUT.put_line ( 'l_flag = '
6 || CASE l_flag
7 WHEN TRUE
8 THEN 'true'
9 ELSE 'false'
10 END
11 );
12 END;
13 /
l_flag = true

PL/SQL procedure successfully completed.

SQL> commit; --不要忘了提交，不然不生效

Commit complete.

2.验证登录密码是否正确
2.1 通过fnd_user_pkg.validatelogin进行验证：
演示：
SQL> DECLARE
2 l_flag BOOLEAN;
3 BEGIN
4 l_flag := fnd_user_pkg.validatelogin ('sysadmin', 'welcome2');
5 DBMS_OUTPUT.put_line ( 'l_flag = '
6 || CASE l_flag
7 WHEN TRUE
8 THEN 'true'
9 ELSE 'false'
10 END
11 );
12 END;
13 /
l_flag = true

PL/SQL procedure successfully completed.

2.2 通过fnd_web_sec.validate_login过程进行验证：
演示：
SQL> SELECT fnd_web_sec.validate_login ('sysadmin', 'welcome2') FROM DUAL;

FND_WEB_SEC.VALIDATE_LOGIN('SYSADMIN','WELCOME2')
