William,
I am puzzled by your comment that on Windows " you are required to
install an additional
layer of software on your server." I have just configured DataGuard "out
of the box" on a 64-bit Windows 2003, Oracle 10gR2 EE and it is working.
Perhaps the admin who did the windows installation did something I am
unaware of. I'm not sure if I am misunderstanding your note or if there
is something I am missing.
Thanks.

I would just like to throw in a personal observation on 64 bit Windows
2003, Oracle 10g release 2 Enterprise Edition. DataGuard is clutter.
In order to utilize DataGuard you are required to install an additional
layer of software on your server. File based replication using
something like dfs to ship your archive redo logs works much better in
my personal opinion and doesn't tie your hands with a gui. I guess I am
hard core and prefer to do things by command line. BTW - what happens
when you have gui problems with DataGuard? This is yet another layer of
software waiting to cause you headaches. I guess I am old school...

That's correct. In fact the Oracle 7 docs were the chief resource that
went into building the standby that became the presentation and
scripts Jeremy referenced earlier. Things that are worth considering.
Are you expecting to do switchover or failover? You need to license
the standby. Do your dbas understand standby databases or do they just
know dataguard? What should be your method for detecting and resolving
gaps? How are you going to make the app resilient? Some of these
obviously apply to dataguard as well. I guess in summary I'm saying
that manual standby works just fine technically but there are a bunch
of management and other 'costs' some of which dataguard handles
directly for you. Incidentally I can say that should you ever give a
'you probably don't need ' presentation, having Tom Kyte, the product
manager (Larry Carpenter) and an industry expert (Carel-Jan Engel)
sitting right at the front concentrates the mind wonderfully.
