>> look for a mix with an attempt to think
I think this is the direction we are going with this book. Arup Nanda who
did a lot of 10g NF coverage for is doing a lot of commentary in
the book (much like Jonathan Lewis did in the 10NF book which I think was
priceless - Thanks JL). The added commentary I've seen thus far is such
added value. Also I'm trying to add value by adding some of my personal
experiences with things. Like I've said before though, page count is always
limited and that is *so* frustrating and often requires that you cut stuff
you wish you didn't have to.

For everyone who has left comments about OEM vs. PL/SQL, the theme seems to
be the same as that noted in the post below from Niall, do both and augment
with some additional information and experience. I'll do what I can. Keep in
mind that this is a brand new release, and this is an early adopter kind of
book. So it's difficult to give a lot of real "production" experience in it
(For example something like this takes ten hours to run if you have a
database > 1TB), though I am running in several different environments, in
fact I'm using more environments for this book than I have for either of the
previous new features books. I can tell you that the entire book will be
checked against the production code before it goes to print.

Finally, I have had questions in the past about why I stopped blogging at my
blog site There were a number of
reasons for this, but I've decided to start up again, so I've added a new
entry. I'll be adding Oracle related stuff in the near future so I hope you
will check out the site once in a while.

Thanks for all your feedback. It is my desire to give the Oracle community a
book that will do everyone some good.

  Hi Robert

  I like seeing both. What I really don't like is a book (or course or
presentation) that is full of how to do x in OEM, now how to do X in pl/sql;
how to do Y in OEM now how to do Y in PL/SQL it looks like a lazy author
regurgitating docs. So I guess in a wish list that likely doesn't fit with
publishing deadlines I'd look for a mix with an attempt to think, which
interface makes more sense for most of my audience for this task. So for
example when dealing with RMAN I wouldn't dream of covering the EM
interface, when using ASH I'd be drilling down through the EM graphs, in
both cases because I think those routes make the most sense for most people.

  cheers and good luck

    Folks... I'm writing the 11g New Features book right now (It's up on
    for pre-sales, so I'm told I can mention the book, but I can't talk
    11g, so please don't ask). As I'm writing I find that I'm in a bit of a
    quandary, so I thought I'd ask you what your preference is.

    If you have used some of the Advisor features in 10g, for example, you
    that there are pretty easy to use OEM interfaces into the advisors, and
    there is the rather long, involved use of various supplied packages
    available that allow you to run the advisors.

    In this new book, I'm considering biasing my coverage to OEM for a few

    1. OEM is less complex to use.
    2. Adding coverage for both will take up many more pages. When you are
    writing a book you are limited to a page count range, so depth is
    based on this too.
    3. The Code route, in and of itself, can be complex. I'm not sure if
    worth the extra time to add the code in some cases just because of this

    I'm wondering if anyone who has used these features or suspect they will
    them in the future has a preference. In some cases, if page count
    I'll do both. In some cases I need to select either/or due to page count
    considerations. In the past, I've been very heavily code oriented and
    relegated OEM to the background, but now I'm thinking of moving in the
