Manish, >Has any one of you configured a workable solution using >Hitachi shadow image and 9205 for duplicate database creation?

Regardless of whether you use Hitachi ShadowImage or EMC SnapCopy (or similar), you _will_ need to place the whole Database in Hot Backup mode prior to splitting the mirror. There is a definite time period between start to finish of the various behind-the-scenes operations and any DB level changes that occur during this period would otherwise result in a fuzzy backup that can be avoided only by a Hot backup. In any case, the whole point of using a ShadowImage is to reduce the time taken to backup an online database while the tablespaces are in hot backup mode (which otherwise would lead to a large amount of redo generation). Sorry buddy - needs to be done! [And we have been using this for a 300Gb Apps database for the past 4 years with no issues - one of my fellow DBAs did try a non-hotbackup recovery test and ended up with fuzzy files].
