Home -> Community -> Mailing Lists -> Oracle-L -> Re: ops vs standby
part 1:
unless your application is designed for ops, you may (please note MAY) have problems with pinging. This has been alleviated in 8.1.6 I believe, but I haven't dealt with it firsthand.
OPS is NOT redundant, at least the database isn't. Standby is a copy of the database on another machine, OPS is another instance on a different machine. An instance is NOT the physical files of the database, but rather the processes associated with running the database.
Backup -- irrelevant either way, you do a hot backup. OPS you'll have to back up additional archived logs I believe.
With OPS you will also have to deal with raw partitions. If you have a really good SA (and a good relationship with this person), then you have no problem.
Part 2:
sorry -- dunno. But I do know that a database link only goes in one direction, so if you set one up from the secure db to the one outside the firewall, no one should be able to get into the secure db using it.
