Re: RE: Error: dbspace chunk

Nah, he's just following Joe's advise - which was to touch a file called rootdbs in a newly created /chunks directory. So /chunks/rootdbs will have a size of zero. Which is less than 20000. :-) >>> "Obnoxio The Clown" <obnoxio@hotmail.com> 06/09/00 10:35am >>> Uh. /chunks/rootdbs isn't what's in his "extract from onconfig". So he must be using a different onconfig..... >From: Watson Paul <Paul.Watson@fefc.ac.uk> > >Can you dd in from /chunks/rootdbs as informix??
