This onmode command must be Informix-specific, i.e. not part of a typical Unix distro.

Isn't this like double checkpointing, or did I miss something? Why not just checkpoint more often than every 10 minutes?

Not in any of my databases. I don't force any writes to disk that the RDBMS doesn't do for me automatically. I don't know very many DBAs who do....
