RE: Re[2]: Datafile Migration Tool

[JOE TESTA]

Last i checked there was no direct=y on imp only on exp (ok and sqlldr) :)   joe >>> [EMAIL PROTECTED] 08/16/01 09:18AM >>> Alex, It's tough to guess how long an import will take.  It all depends on how many indexes and constraints you have - these are what take the most time at import time.  The data gets sucked in real fast.  Using Direct Load really speeds the import up but, again, rebuilding the indexes takes forever. Gene is correct in that export is extremely fast.

How long do you think import will take for 200G database? - about 60 hours?

If I am reading this correctly, he is proposing to provide a tool that copies datafiles directly from one OS to another. While this is an interesting trick, I'm not sure there's a large market for it. >From: Scott Shafer <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> >Subject: Re: Datafile Migration Tool >Date: Tue, 14 Aug 2001 12:00:53 -0800 > >Not to be a smartass, but don't most OS's already have ftp built in? >What kind of value-added are you proposing?  Just curious... > >Scott Shafer >San Antonio, TX > > >K Gopalakrishnan wrote: > > > > Hi , > > > > Will there be a market if I give a tool which migrates Oracle database > > from One OS to another OS.
