I have installed HRMS 9.1 and PT 8.52 on Windows 2008 R2.

when i try to open app designer, I am getting error

"File: SQL Access ManagerSQL error. Stmt #: 2 Error Position: 0 Return: 404 - ORA-01017: invalid username/password; logon denied File: SQL Access ManagerSQL error. Stmt #: 2 Error Position: 0 Return: 404 - ORA-01017: invalid username/password; logon denied "

then i again ran below script

set log c:\temp\test1.log;

UPDATE PSSTATUS SET OWNERID = 'SYSADM';
UPDATE PSOPRDEFN SET SYMBOLICID = 'SYSADM1', OPERPSWD = 'ps', ENCRYPTED = 0 WHERE OPRID = 'PS';
UPDATE PSACCESSPRFL SET ACCESSID = 'SYSADM', SYMBOLICID = 'SYSADM1', ACCESSPSWD = 'sysadm', VERSION = 0, ENCRYPTED = 0;


GRANT SELECT ON PSSTATUS TO people;
GRANT SELECT ON PSOPRDEFN TO people;
GRANT SELECT ON PSACCESSPRFL TO people;

REM - ENCRYPT PASSWORD
/
SET LOG c:\temp\encrypt.log;
