Database:, 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] [ecid: 1268209318:,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

ORA-03114 / 03113 while running dbms_java package

Got errors (ora-03114 / ora-03113) while running any dbms_java script on a 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.

Using http://localhost:8080 at APEX(11gr1), horrible performance

I had to install a 11g release 1 on Windows for demonstration purpose of APEX. APEX comes standard with 11g, so that's nice. When using Embedded PLSQL you don't even need Apache... But when I'm using http://localhost:8080/apex/apex_admin, the login-page popped up after a minute or two.And every page I use has the same horrible performance. Using the loopback by the way like on the server gives the same result.

Determining compression-factor 11g release 1

Working on 11g, release 1 (, managers wanted to know what kind of compression factor we achieved in the datawarehouse. Amount of (compressed) data: just about 1,5 TB. In all my naivity I thought Oracle delivered the package 'DBMS_COMPRESSION' which will show me the rate of achieved compression per table. But first of all, in 11gr1 there was no package like 'DBMS_COMPRESSION', this is only delivered with release 2.
