Both

Is
there any interest in sharing that kind of sales information? For, say, a Sun
6500, 12 processors, 8GB RAM,
<FONT face=Arial color=#0000ff

Just a

I usually don't do these kind of posts... but I've seen a lot
of activity on this topic lately.
What is really the problem we are trying to solve here?
Maybe we are using the wrong tool.
If you are looking for data protection in the event of a
failure, or disaster... Or if you are trying to create a real time reporting
instance. And you are using standby databases... there is a better
solution.
We provide a product called SharePlex for Oracle... it
continually scans the online redo logs for any transactions on the tables that
are critical to your environment. It takes these transactions, and sends
them to a target machine over TCP communication, and posts them via standard
Oracle SQL. The target system is completely open and available, while we
are posting to it, for reporting and/or verifying that the data is there and
available for use in case of a failure or disaster at the primary site.
It can even be used in a peer to peer replication scheme as
well.

Sorry about the 'sales announcement' but this list is
for helping people, and trying to solve their problems... I see this as a
solution.

Quick question. Is it a fair statement to say that using
Oracle's hot standby database allows you
recoverability up to the last archive log, but would
NOT recover to the latest redo log (prior to a log switch). In
other words, the potential to lose transactions is
very high if you depend on this for failover (not good
for e-commerce type databases). Would it be possible <FONT
size=2>to somehow mirror redo logs across to the failover server and apply
them when activating the standby database, or is the
only real solution clustering or something like
DoubleTake?
Am I making sense?
Thanks,
Ed
