Actually, logical standby database does have a hidden cost because you need Data Guard which is licensed
separately. The product that mimics SharePlex is called Oracle Streams and it is a redo log based replication
tool, sort of Logminer on steroids. By the way, logminer was published because of the Quest who reengineered
the format of redo logs and based recovery mechanism on reading the changes from the logs and applying
them to "replicated" database. Neither logminer, SharePlex nor Streams can handle DDL. One has to propagate
schema changes using Quest Schema Manager or the same thing from Embarcadero or, for masochists, OEM Change
Management Pack. I used every expletive in the book while I was testing OEM and I even invented a few of my own.
If you opt for any of those tools (and Data Streams is a pretty cool stuff, based on the demos, white papers from OTN, marketing brochures and spam about the database enlargement), you will also need a schema manager tool.
Quest Schema Manager is a very good tool which I tested extensively. I'f you decide to go cheap and use trigger/stored procedures based replication ("advanced replication"), you'll need a gun, preferrably 44-magnum. That is known as "go ahead, make my data" option. Do you feel lucky?

    SharePlex does the same basic thing that Oracle does for the logical
standby, as a matter of fact if your running 9i why not use that instead of
Quests's pricey tool?  I don't believe there is any additional cost to using
logical standby over the second server license that your going to have to
pay anyway.

Quest is trying to sell us a product named SharePlex.  It sounds very
attractive, but then sales people are supposed to be good at that.  We are a
mid sized company, about 2.2 billion per year, running Financials 11.5.7.
We are interested in this for HA and for reporting instance use.  

We use Cognos as our query tool and the owners of this product tells me that
we can't tune the SQL it emits.  It makes pretty poor choices, which is not
surprising for a gooey, sticky tool designed for end users.  It is sort of
pretty and if you can drool you too can generate cross products.  Anyway ,
I'd like to get them off the production box.


Does SharePlex allow you to stay close to the production instance in time?
Does the store and forward work well?  Do you love it?  Hate it?  Anything
you'd like to say about this product I'd like to hear

Thanks in advance
