It’s not my fault really. When running an installation, presented with the option of (a) do a bunch of stuff and wait to continue the install later or (b) tick a box and continue now it’s a better man that I who would opt for option (a). When I recently installed OBIEE 11g, I was prompted to get a script run as root to set up the inventory, or tick “Continue Installation with local inventory” to continue with the install.
