}I don't know if this works for Online 5, but creating a clustered index

The problem with the cluster index approach is: you have to have a lot of
free space in your dbspace in order to accomplish that.
Why don't Informix provide us DBAs an utility to reorganize tables (or
dbspaces) ? I've got to deal with this stuff often in volatile tables.
