Last updated on FEBRUARY 15, 2019

Applies to:

Portal - Version 9.0.4 to [Release 10g to 10gR2]
Information in this document applies to any platform.


Oracle Application Server 10g Release 2 (10.1.2) Support Status and Alerts Doc ID 329361.1
ALERT: Premier Support Ends Dec 31 2011 for Oracle Fusion Middleware 10g 10.1.2 & 10.1.4 Doc ID 1290974.1


When the SSO HTTP Server and the middle tier WebCache (or HTTP Server if the WebCache is not used) are running on a single machine and using the same ServerName, you cannot log into OracleAS Portal when using the Microsoft Internet Explorer (MSIE) browser. For example, this problem will occur if an Infrastructure installation and an OracleAS Portal and Wireless Application Server middle-tier installation are both installed on a single machine.

After submitting the login information, the browser is redirected to the Portal home page and the following error is raised:

Error: Unexpected error encountered in wwsec_app_priv.process_signon (ORA-06502: PL/SQL: numeric or value error: character string buffer too small) (WWC-41417)


Error: The decryption of the authentication information was unsuccessful.
This may be caused by data inconsistency, an incorrect encryption key in this application's configuration, or an illegal access attempt. Please notify your administrator. (WWC-41454)



The Portal middle tier and the Infrastructure have been configured to be accessed using HTTPS protocol.
