Re: Ontape to Disk - HP_UX

The PATROL DB-Basics Utilities for Informix (formerly ztools) from BMC have facilities to do backup to multiple files or devices using ontape/tbtape. Check out: http://www.bmc.com/products/pat/dm/zutpp.html for mor information. I partisipated in the betatesting of ztools some time ago, but never got arround to test this function. Judging from the quality of the other tools there is however every reason to believe this should work excelently.

Any ideas on :"faking out" ontape to write to "multiple" 2 GB files, or change TAPEDEV :during the archive would be greatly appreciated. : :Melissa Schornheuser :Farmland Industries, Kansas City, MO :mgschornheuser@farmland.com Nils.Myklebust@idg.no NM Data AS, P.O.Box 9090 Gronland, N-0133 Oslo, Norway My opinions are those of my company The Informix FAQ is at http://www.iiug.org
