I'm wondering if anyone who has used these features or suspect they will use them in the future has a preference. In some cases, if page count allows, 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 really relegated OEM to the background, but now I'm thinking of moving in the other direction.
I had the same question when I wrote my chapters, and ended up showing both. Reviews showed that the readers like this approach. I followed up the book with a COLLAB paper that went under the hood so I can show more in-depth stuff. On a practical side, as a working DBA that needs to manage scores of databases, I *cannot* afford to login to multiple DB Control (or multiple links from Grid Control) instances to check. To enable alerts, one needs descriptions/pointers to the right set of WR views/tables and SQL that can extract this information and massage/summarize it for you... And I believe that providing this part via a book is the author's responsibility.... In other words, you need to cover what Oracle's marketing material and WPs cannot do in their glossies, and show some of the down-and-dirty that Oracle will NOT show you via the documentation....
