APEXblog.nl - Tips and Tricks

About This Blog:
I (Richard Weug) started this blog primary for myself to save all kinds of Apex tips and tricks in one place. To use it as a place to write down how I used some coding in my own projects, but also to copy and paste all kinds of articles I find on the Internet. (So I never have to wonder on what website did I read about??? When I see something interesting I collect the content so I have my own archive/knowlegde base.

Upgrading to APEX 4.1 on Oracle 10.2.0.3

Written by Richard Weug on Wednesday, 25 January 2012 09:03. Posted in Installation

I have been upgrading a lot (and I mean a lot) of APEX environments to 4.1 and never had any issues until ...
well until I encontered the infamous error : "ORA-06502: PL/SQL: numeric or value error: associative array shape is not consistent with session parameters".

Upgrading APEX is very simple. You just have to run the apexins.sql script and voila.
So the question is , what to you do if this script fails.
