Installing and administering Tungsten Replicator - Part 2 : advanced

Switching roles

To get a taste of the power of Tungsten Replicator, we will show how to switch roles. This is a controlled operation (as opposed to fail-over), where we can decide when to switch and which nodes are involved.

In our topology, host1 is the master, and we have three slaves. We can either ask for a switch and let the script select the first available slave, or tell the script which slave should be promoted. The script will show us the steps needed to perform the operation.

IMPORTANT! Please note that this operation is not risk free. Tungsten replicator is a simple replication system, not a complete management tool like Continuent Tungsten. WIth the replicator, you must make sure that the applications have stopped writing to the master before starting the switch, and then you should address the application to the new master when the …

Joining the PHP BBQ in Hamburg and Kiel

There must be something that gets coders and barbecue together. In Australia, I was invited to a hackers barbecue, while at FrOSCon, the Saturday evening meal is a grill fest.
It seems just right that the PHP coders in Germany are getting together with a BBQ Tour, starting on Monday, June 15, and touching seven German towns in one week.


I will join the happy campers on Saturday, June 20, in Hamburg, and finish off the tour in Kiel the next day.
The event is open. However, for …

MySQL Campus tour at USC - Slow start, brilliant ending

The Southern California branch of the MySQL Campus Tour is almost over.
At the USC, attendance was very good, and even better was the enthusiasm and the participation we met. The meeting didn't start well. Our hotel is 11 miles away from the USC campus, and we figured out that heading to the campus 1 hour before the planned time ought to be enough. After 65 minutes, we had done exactly 7 miles, in one of the worst traffic jams that I have ever seen, but the locals tell me that it's pretty standard stuff down here. Anyway, we started 20 minutes later than expected, and we were pleasantly surprised that nobody had left, and a faithful audience had been waiting …

Quiet excitement at UCLA

The second leg of the Southern California MySQL Campus Tour was at UCLA.
There was less attendance than Cal Poly. Only 22 brave souls who endured a lengthy session with a long tail of Q&A.
The excitement came on my way back to my hotel, 25 miles from the campus. Distances have a different meaning here. A few dozen miles is just a tiny portion of the town, and so I found myself once more driving the endless highways of Los Angeles.

When I was almost home, I saw all the cars in front of me stopping, for what I …

Cal Poly - A success

The MySQL Campus Tour 2009 started very well at Cal Poly, San Luis Obispo, CA.
Despite the warm day, which would have tempted many attendees to desert the conference and go to the nearby beaches, there was a full room, with 82 people, many of them standing.
The presentation was appreciated (and so was the pizza that Sun had delivered to the classroom). I did the main part, while Sheeri was actively contributing with witty and informational remarks.


Most notable, after the session, we continued the cultural exchange to a local restaurant that bears my name (correctly spelled!), where this heap of bread caught my eye. Thanks to …
