What would a second edition focus on? It isn't hard to come up with a short list. The IT industry has been moving in some new directions. In particular there's a lot of excitement building around open source databases; our customers are increasingly asking about them and beginning to deploy them in earnest. Solaris 10 opens up a lot of new possibilities (Containers/Zones and DTrace just for starters), and Open Solaris introduces all of these topics to a wider audience. There's nothing significant in the first edition about Oracle RAC, an omission that should be corrected. And for most of the products covered in the first edition, there are later versions, feature updates, and new insights to be explored.
If you think there should be a second edition, please let me know. And feel free to suggest the topics you'd most like to see covered.
I'll let you know if and when there's more news...
