Peter!

I'm glad to read your response. If I may I would like to explain my situation.

I'm a newbie to SQL; I'm currently researching Oracle 7.x & Oracle 8.x since the front end s/w we're buying needs a Oracle box (v7.x they say).

Since this will be a 24x7 app I need to have a *disaster recovery* plan. Also there's this nagging issue about *what* platform ... actually NT or NW (unfortunately not UNIX).

First the platform issue. I have NW boxes here running redundant (standby/failover). I have *a* NT box but my plan is to get rid. Mainly unstability, high h/w requirement, resource hog, etc. etc. (this is a server class box too).

Front end app developer says Oracle on NT is easiest. I'm assuming that Oracle on any platform, theoretically, should be the same? The API(?) set the front end uses to access Oracle should be same across platforms, right?

I want to go Oracle on NW; I've heard that Oracle on NW scales better although Oracle can't officially push any particular platform.

As far as redundancy goes I would like to figure out what options we have for a *failover* (hot spare/standby setup) in the main site & if I can setup a hot spare in my remote office. Both of these hot spare/standby should have the up-to-date DB. This way if our man site is bombed then the service can be up in theremote office. For the latter what kind of dedicated bandwidth is necessary (T1, T3, etc. etc) or if there are any other technologies from Oracle or someone else?

The clustering technology by people like Compaq & MS for the NT platform looks okay but I'm not really gunho about NT platform.

I know for a newbie this is a lot of question.

TIA.
