Error when attempting to create connection -- Discoverer

Question

Hi.
Application server 10g 10.1.2.0.2
Discoverer (business intelligence)
HP-UX
10g Database
We have a new installation of the application server with Discoverer. If we try to create a connection from the Discoverer connection page for plus or viewer, we get the following error:
Error
A connection error has occurred.
- oracle.discoiv.controller.DiscovererControllerException: Attempted to exceed 2 oracle.discoiv.state.LoginTransitions History: oracle.discoiv.state.LogoutTransition oracle.discoiv.state.LoginTransition oracle.discoiv.state.LogoutTransition oracle.discoiv.state.LoginTransition
- Attempted to exceed 2 oracle.discoiv.state.LoginTransitions History: oracle.discoiv.state.LogoutTransition oracle.discoiv.state.LoginTransition oracle.discoiv.state.LogoutTransition oracle.discoiv.state.LoginTransition
- Attempted to exceed 2 oracle.discoiv.state.LoginTransitions History: oracle.discoiv.state.LogoutTransition oracle.discoiv.state.LoginTransition oracle.discoiv.state.LogoutTransition oracle.discoiv.state.LoginTransition
We even created a user with no special characters/numbers. Simply text. It has not worked for any user. I can create a public connection without any issue. I do indeed have the checkbox selected for creating private connections.
Anyone else? Have you seen this? Resolved this (even better!)?
Thanks!

Hi everyone
There is a known issue when using AIX, HP-ux or Linux against a 10.1.x database. If this is your scenario, then you need to obtain and read the appropriate release notes. For your information, the necessary instructions are attached here:
When using Oracle Database 10g Release 1 (10.1.x) for the Metadata Repository or after upgrading the Metadata Repository to Oracle Database 10g Release 1, you might see the following error on the OracleBI Discoverer Plus Connection pages, the OracleBI Discoverer Viewer Connection pages, and the Public Connection definition page in Application Server Control:
The connection list is currently unavailable.
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "ORASSO.WWSSO_API_PRIVATE," line 258
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "ORASSO.WWSSO_UTL" line 728
ORA-28231: no data passed to obfuscation toolkit
ORA-06512: at line 1 Unable to retrieve connection list
To resolve this issue, make the following changes in the Metadata Repository database:
1. Edit the init%ORACLE_SID%.ora file in the following location:
DB_install_home/dbs
2. Add the following line to this file:
event="10946 trace name context forever, level 36"
3. If an spfile%ORACLE_SID%.ora exists in either the dbs folder or the database folder, rename the file to spfile%ORACLE_SID%.bak. Changes to init%ORACLE_SID%.ora are not loaded if the database server finds an spfile.
4. Log in as a sysadmin.
5. At the SQL prompt, shut down then start up the database server.
6. Restart the OracleBI Discoverer server using the command opmnctl restartall.
You can get the full AIX document by clicking here: http://download-east.oracle.com/docs/html/B25207_03/toc.htm
The Linux document by clicking here: http://download-east.oracle.com/docs/html/B25824_01/toc.htm
and the HP-ux document here: http://download-east.oracle.com/docs/html/B25199_03/toc.htm
and then searching for 06512.
Neither Windows nor Unix appear to be plagued this way, at least not so far. :-)
I hope this helps
Best wishes
