Okay... I'll buy that.  

However...  

On the logical standby, can I create users that are not in the primary database? I'm trying to multi-purpose this database rather than "just" being a transformation database between solaris source and linux destination by keeping historical data and giving us an alternative place to run some batch reporting. But I don't want to rely on the fact that the data and structures are all representative of the up stream primary.  

*****The trick to guard only the tables that are coming from the primary database. That is done with the commandalter
 database guard standby;

Then you can create tablespaces, users,materialized views,indexes etc specific to the logical standby which are not on the primary.

Or am I stuck with "just" having the ability to structure the whole database as if it were the primary?

AFAIK
All it does is ship the logs from one db (target) to another (standby) You cant filter anything.

We are trying to create a logical standby database (solaris) using data guard so we can use downstream data capture to populate a reporting database (Linux) for historical reporting.  

Any chance anyone has done this and can give me some pointers on what I'm probably going to do wrong?  

Can I set rules up stream on the source database on what tables I don't want to have included in the data guard log apply or will it just apply everything? I'm trying to tough my way through the documentation, and am stuck at the "uniquely identify rows" part. It seems that EVERYONE on the source system has a plan table and that doesn't have a primary key. Do I care? Will it complain?  

Should I create a primary key rely disabled on ALL of those plan tables?  

Thanks for any advice
