Steve talked about an undocumented page on his site
Steve's blog entry was called Updated Dynamic JDBC Credentials Example and it told about Steve updating his example 14 for dynamic JDBC credentials for Model 1 and Model 2. Steves undocumented examples page is a great collection of snippets and examples and information.
What has this to do with Oracle security? - Nothing specifically. For me hard to find undocumented or internals knowledge is always worth reading for anyone interested in security. To be knowledgeable about security also means that you need to understand the products and the technology that you are trying to secure - how else can you secure them? Hard to find or undocumented information just gives that extra level of knowledge so itís always worth collecting and reading it. For me itís a learning thing.
