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?
