The big differences between the two engines are: 1. online utilizes shared memory and bypasses the os to 'manage' the disk. 2. online can utilize either cooked or raw devices. se can only use system disks. 3. online is for high volume oltp applications and requires more 'baby sitting'. se, although i have seen some 'large' applications, is for smaller applications but requires far less attention to maintain. 4. price - online is more expensive than se. > Informix NET/Informix STAR > --------------------------------- > > My understanding is that Informix STAR is what allows simultaneous access > to multiple OnLine Servers.
