There are a couple of books on the market already which cover 11g features.
As always many of them do not really cover a lot of the new features because everything is so new and the books were written under preasure. So the have the “COVERS 11g” on the cover but inside it is mostly 10g stuff.
Here is one which is a MUST READ for everybody who is interested how Automatic Storage Management (ASM) really works:
Oracle Automatic Storage Management
What makes this book especially interesting is the fact that the authors are the Oracle developers of ASM themselves, Nitin Vengurlekar and Richard Long, and Murali Vallath., the president of the RAC SIG, plus the architect of the technology Bill Bridge who wrote the foreword for the book .
This book keeps its promises and covers the 10g and 11g features of ASM in detail.
And it is an easy reader with a sence of humor:
“The ACD is a log that allows ASM to make atomic changes to multiple data structures. It is similar to the redo logs used by the Oracle RDBMS. Each instance gests a 42 MB chunk of the ACD. (As Douglas Adams explained in Hitchiker’s Guide to the Galary, “42″ is the answer to the ultimate question of life, the Univese and Everything.) …
This is the way of reading I like!!
Thank you guys, I love it
