Info on OnLine Dynamic server

In one of the Informix Product list I came accross a version of OnLine called "Informix OnLine Dynamic server". It was described as a "multi-threaded OnLine engine capable of doing SMP and Uniprocessor". Can I get some more Information on this? Like what version of Informix is this (5.x or 6.x)? How different is it from OnLine for SS1000 and Solaris 2.3 (Which is a multi-threaded, SMP architecture)? availabilit? I'm in the middle of porting our clinet's application on SS1000 and Informix OnLine 5.01, but it looks like I should be probably using "OnLine dynamic server". Any info on this appreciated. Thanks. ----- Yogen ICon Inc. (212)972-4266 yogen@IConNet.COM
