The customer is using Firefox, 3.5 in this case, and Internet Explorer (6!). Suddenly the application does not work anymore for a lot of clients, as a matter of fact, the firefox-users. They had upgraded their Firefox to 3.6., and got the message that an add-on must me installed ( appears to be the JRE ) . After installing this, it still does not work.
Database: 10.2.0.2, Apex 3.2.1. Application works fine, until there's a bit of load of users logging in. They get the following message (derived from error-logging of Apache): [Wed Mar 10 09:21:58 2010] [error] [client 127.0.0.1] [ecid: 1268209318:188.8.131.52:1543:0:26453,0] mod_plsql: /pls/apex_app/wwv_flow.accept HTTP-404 ORA-06550: line 22, column 3:PLS-00306: wrong number or types of arguments in call to 'ACCEPT' ORA-06550: line 22, column 3:PLS-00306: wrong number or types of arguments in call to 'ACCEPT' ORA-06550: line 22, column 3:PL/SQL: Statement ignored
Got errors (ora-03114 / ora-03113) while running any dbms_java script on a 10.2.0.2 database. Took a while, but then I found out it only happens when I'm connected through sql*net. Directly on the server gave no problem at all. And... it only occurs on my Test-environment, not in development, and not in production.
