As of Oracle RDBMS 9i, time is expressed in microseconds, rather then seconds, years or lifetimes. BTW, you left out the infamous "dog years". Backing up and restoring a single 128TB file would be an interesting exercise. Please, do it and then post the result, appropriately expressed in microseconds, using, of course, the binary notation. That way, we will be able to know the exact answer to your question. Everybody will enjoy screen upon screen of zeroes and ones. -- Mladen Gogala Ext. 121 -----Original Message----- From: Jared Still [mailto:jkstill@xxxxxxxxx] Sent: Thursday, December 09, 2004 6:43 PM To: MGogala@xxxxxxxxxxxxxxxxxxxx Cc: greg.loughmiller@xxxxxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: Re: Oracle9i data file size limitations on HPUX 11.11 How long does it take to restore a a 128 TB file? a) 42 minutes b) 42 hours c) 42 days d) 42 months e) 42 years f ) 42 lifetimes g) all of the above Jared -- //www.freelists.org/webpage/oracle-l
