hi,
Could someone please tell me what should be the value for archive destination, if i want it to be a tape drive. will something like /dev/rmt/0 will work? first of all, can we archive directly to a tape drive? what are the issues involved? I would appreciate very much the help.
Thanks in advance
sure, you can easily archive on a tape using cpio or others (for example cpio -oxcvB > /dev/rmt/0mn)
and you should use /dev/rmt/0mn since :
0m => auto rewind between volumes
0mn => no rewind
Can you? Sure. Personally, I would archive to disk and periodically copy to tape. Most likely, your archiver will not be able to keep up with LGWR. LGWR will then hang the instance until he can continue.Quote:

it works fine, I've been using that on HP servers for a long time, for hot and cold backups, and it works fine ;)
note : on HP-UX, you can use ftio instead of cpio, it is much faster !!! I don't know for other platforms ...
