OTN Tour of Latin America 2015 : The Journey Begins – CDG Airport

ace-directorI’ve been in Charles de Gaulle airport for about three hours now. Only another four to go… :)

I tried to record another technical video, but you can hear kids in the background. Now the timings are sorted, it should be pretty quick to re-record when I get to a hotel, so that’s good I guess. I’m not sure I can face doing another one today.

My YouTube channel is on 199 subscribers. About to ding to the magic 200. :)

Hopefully I will get power in Paris, so I can do some stuff on my laptop…

Cheers

LogXptMode=SYNC

LogXptMode=SYNC

The point is that we need to wait for two acknowledgements by RFS (got it & wrote it) before we can write the redo entry locally and get the transaction committed. This may slow down the speed of transactions on the Primary, especially with long distances. Now to the new feature:
