Kind of neat how as soon as product a has a new feature its apologists declare it the essential and distinguishing feature in the marketplace..

Now, if it works as smoothly as you describe - that's great, and I'll look forward to using it. On the other hand, in my experience with MPP databases (primarily Informix on AIX using SP2), I could go a year without having to reboot any nodes. And when I did, it was often due to a configuration change to the frame - so I had to take all of them down anyway.

So, nice feature, but hardly essential for most applications. Received on Thu Feb 05 2004 - 08:32:25 CST
