Hi List, I am using RMAN to duplicate our live DB to another identical machine. Full On-line backups are taken 5 days a week (file is 25Gb on disk), each one includes *all* archive logs. I have been asked to see if we can use a different nights backup for the duplication process, other than the last backup taken. I can't find anything on MetaLink and Rob Freemans book only mentions that Duplicate uses the last good backup. Is this possible?? If so how? *Specs:* *Oracle: 9.2.0.4 64-bit* *O/S: Solaris 2.8* Many thanks -- ~~~~~~~~~~~~~~~~~~~~~~~ David Cheyne BA(hons.) Oracle Database Administrator
