RAC is most certainly a significant upgrade to and renaming of OPS. There
is absolutely no doubt about it. At Oracle Open World 2000, all the Oracle
OPS people doing presentations found out about the name change only a few
weeks before the conference and
I attended the Oracle 9i opening yesterday at Oracle HQ in the UK, and one
of the main points they discussed about 9i, was the use of Real Application
Clusters (RAC). Of course you have to be running on Compaq hardware at the
moment, but it takes the need for a standby away, as you essentially

Mark -
I saw the same presentation @ IOUG. Do you recall if they were running on the
Compaq Alphas? A few days ago I recall someone saying that they would be wary
of Oracle continuing support for Oracle on the Alpha chip, since Compaq has
pretty much written it off.

Mark, isn't RAC just the upgrade for OPS? Then that would
make it a 'standby' for the instance, but not a standby for the

Am I misunderstanding something?

No it is not the upgrade of OPS as I understand. They even put OPS down
themselves saying that it was sparsely used, and far to complicated to set
up.
What RAC does, is essentially link every machine together in to a cluster,
then each physical machine can touch the same database concurrently
Brian,
They didn't actually say what hardware they ran on other than Compaq.
There was a little discussion about this after the actual presentation with
other attendees also, but I shouldn't get too worried about de-support of
this solution at all. The actual day was an Oracle/Compaq release day

Anyone know if the standby in 9i can be in readonly mode while the logs are
being applied? I've heard about this as being the case and also that this isn't
the case.
Thanks, Dave Turner

says the standby can be in one of 2 states, open for read-only
or in managed recovery mode. if its open in read only, it can't have logs
applied. I've not gotten around to testing that 9i concept yet.
although it looks like it will be kewl to
Thanks. If anyone else knows of anything out there for really high volume replication
over
a WAN it would be appreciated. I was under the impression that banks, credit card
companies, and
telephone companies were replicating there data using Oracle but it doesn't look like
it.
Anyone know
Most of the high-volume replicated sites that I have heard of over the past few years
use Quest's Shareplex. I've had no experience with Clustra.

Hmmm. Banks are two different worlds,
Can you tell us please what are specifics in configuring database for such
load.
