Apps password is not available in the application files in R12. We can still recover the lost password by creating a decrypt function.

Steps to retreive apps password in R12:

1.Create function Using below syntax

SQL> create or replace FUNCTION apps.decrypt_pin_func(in_chr_key IN VARCHAR2,in_chr_encrypted_pin IN VARCHAR2) RETURN VARCHAR2
AS
LANGUAGE JAVA NAME ‘oracle.apps.fnd.security.WebSessionManagerProc.decrypt(java.lang.String,java.lang.String) return java.lang.String’;

3.Run the below query to decrypt the password


SQL> SELECT apps.decrypt_pin_func(‘GUEST/ORACLE’,’JH89E045BEA551FD01A8D71029ACA879F209U8BD898F451EBDB987C818E7608CE0CC0167BDCAF9D1D04D9C9CEE418CFE615A') from dual;

APPS.DECRYPT_PIN_FUNC(‘GUEST/ORACLE’,’ZG761B2FB6A2C49BC802F57E55AC26637388B4EA99

PASSWORD


4. Verify Database Connection using the password retreived
