Changing the value of LTAPEDEV (from onmonitor--Archive, Tape) to
/dev/null and re-initializing (if possible) will throw a "backup" of the
log to /dev/null which prevents the necessity of backing up to tape. [I
do not know if you actually change the logging status of the database,
effectively disallowing transactions (I doubt this is what you mean), or
if you just stop backing up the transaction logs.] If you can not
afford to re-initialize, then a "nohup ontape -c &" will do it. You can
use ontape all you want with onarchive as long as you don't plan to use
the tapes/lack of tapes together.
The previous response should be thought about: Buy a big, fast tape
drive and don't use onarchive, but ontape/onbar. Look at the Exabyte
Mammoth. 20 GB native (I get 60) in about 2-3 hours for an ontape.
Hope this helps,
