Oracle wiki

I've thought for a while about creating an article about the resources available in Oracle problem solving process. Meanwhile Oracle wiki was born and already exists for about two months. As it is supposed to be shared and editable resource by everyone in Oracle community I thought that it would be a perfect place for my eventual article for two reasons:
1) more people hopefully will read it and probably get some help;
2) more people can add their suggestions how they solve Oracle related problems.
So my first contribution to Oracle wiki is How to solve Oracle Database related problems. Everyone is invited to correct it and/or add some other resources. As well as for other Oracle wiki pages of course.
