What's the purpose of the standby, and indeed of the streams implementation. You might consider making it a logical standby - or having one physical one logical - to meet your requirements.

I'm familiar with the standby database approach...at least an 8i version. Data Guard doesn't look that much different as far as the way to set things up. Oracle Streams looks like it does something similar to a logical standby, using a different process. I'm wondering if anyone is using Data Guard with their primary database also using Oracle Streams to send data to a different database. If so, are there any details to be aware of...like in the case of a disaster when the primary goes down and the standby comes up as the primary...should the standby somehow be configured to use Oracle Streams to pass the data to the database that was receiving it from the primary before the disaster? I have read through some of the documentation, but not all of it, so my questions may be answered in what I haven't read. I'm just curious if anyone else is doing something similar and is interested in sharing their insights/experiences. - Maureen -- //www.freelists.org/webpage/oracle-l
