The phrase "throw more hardware at the project to keep up the speed" is heard all too often among IT professionals. Moore's Law states that computing power will double every eighteen months. However, there comes a time when additional hardware doesn't solve performance problems. This issue is particularly relevant for XML documents. When dealing with…

There are many code debugging tools available to Oracle developers. Some require more effort than others. The author will walk the audience through a debugging session using SQL Developer and how it's used with XML Documents.
