RMOUG, Day 2, ++1

The second day of the RMOUG Training Days event was just as good if not better than the first. I took some notes for some sessions, so before my head explodes from all the information overload, here’s my brain dump of the day’s events.

RMOUG, Day 1, +1

RMOUG Day 2 has started, but there was so much great content yesterday, I don’t know if I’ll remember it all unless I write a few notes here on my learning. My first session of the day was Graham Wood’s session on adaptive thresholds for monitoring in 11g. I didn’t know very much about these … Continue reading “RMOUG, Day 1, +1”

RMOUG Day 2 has started, but there was so much great content yesterday, I don’t know if I’ll remember it all unless I write a few notes here on my learning.

My first session of the day was Graham Wood’s session on adaptive thresholds for monitoring in 11g. I didn’t know very much about these new methods for setting alerts, but they are certain to be useful. Some of the methods for adaptive thresholds were available in 10g, but many enhancements were made in 11g. Most importantly, the cyclic nature of workload has periods that can be automatically determined in 11g whereas in 10g, they had to be specified manually. Graham talked briefly about using DB Time and Average Active Sessions as important metrics for tuning, but for alerting, adaptive thresholds make the most sense. Setting a hard limit means that you will likely miss many issues. If your system is normally 10% utilized overnight, but spends all night at 60% utilization, you would like to know about it. However, during the daytime, if the system normally operates at 75% utilization, a hard alert limit at 80% would have miss the 6x utilization increase from the overnight hours. Adaptive thresholds wouldn’t miss the aberration and would alert you of the 60% utilization in the overnight period. That would allow you time to attempt to resolve the problem before daytime hours start.

RMOUG: You should be here

I arrived in Denver yesterday afternoon for the RMOUG Training Days event. As I’ve written before, this is the first conference I’ve attended (and paid for!) as an attendee in at least 6 years, maybe the only one ever. The coolest part was that the small amount I paid for an attendee registration ($285) has … Continue reading “RMOUG: You should be here”

I arrived in Denver yesterday afternoon for the RMOUG Training Days event. As I’ve written before, this is the first conference I’ve attended (and paid for!) as an attendee in at least 6 years, maybe the only one ever. The coolest part was that the small amount I paid for an attendee registration ($285) has already been totally worth it, and the sessions haven’t even started yet. Many people would pay that amount just for an opportunity to visit with some of the people I got to talk with last evening.

After all, I know of no other conference where you can have meaningful, interesting conversations with all of these fine individuals in a single evening: Mogens Nørgaard, Debra Lilley, Graham Wood, Kevin Closson, Daniel Liu, Gaja Krishna Vaidyanatha, Jeff Needham, Christo Kutrovsky, Mike Ault, John King, Joze Senegacnik, Tim Gorman, Duncan Mills, Lynn Munsinger, and Peggy King. And those are just the people I got to talk to (there were many other well-respected technicians and sharers of knowledge around that I didn’t have time to speak with. I haven’t even gotten to see Cary Millsap, Robert Freeman, Craig Shallahamer, Riyaj Shamsudeen, Tanel Poder, Jeremiah Wilton, Tom Kyte, Iggy Fernandez, or Daniel Fink yet.

This is my first time to RMOUG and you may be thinking that this is some sort of fluke to have all these great researchers and presenters at one event, especially a relatively small event where there are ample opportunities to network with them directly. I’ve reviewed the RMOUG agenda for the last 3 years and this agenda is representative of the quality that they’ve managed to schedule for the event every year. Plus, unlike other conferences, the RMOUG attendee tuition is priced to help them break even, not make a large bankroll. My biggest regret is that I couldn’t manage to get here before this year!
