I have just received a copy of the “Oracle SOA Suite 11g Administrator's Handbook” so as soon as I have read it I will let you know what I think. In the meantime the first thing that struck me was the author credentials, although I have never met either of them as I remember, I have read Admeds blog postings and they are a great community resource, so immediately I am well disposed towards the book. Similarly Arun is an employee of my friend and co-author Matt Wright, and I have heard good things about him from Rubicon Red people.
A first glance at the table of contents looks encouraging, I particularly like their approach to performance tuning where they give a clear concise explanation of the knobs they are using.
More when I have read more.
