RE: Streams capture from an active DG standby

Ghassan,  

I am still experimenting with downstream log capture (archived_log) but have not got it to work yet. There seems to be a shortage of information around it, especially on getting the apply process to work. However that is a separate issue to this.  

In theory I cannot see why you cannot read the redo logs from a standby database (especially if you are using Active DG) and apply those changes to another database, I just cannot see any information anywhere about if it is possible or not.

John
from your last sentence
"

We are looking at shipping redo logs over to the remote site and then capturing transactions on that end to keep other databases in sync, all at the remote site.

"

it seems that you're looking after downstream capture. did you look into it?

In 11G (OEL5 Linux) using Active dataguard does anybody know if it is possible to capture transactions at a schema level using Streams from the STANDBY database.  

I have searched the docs but I cannot find anything to prove or disprove it.  

Even if not using active DG is it possible to do the same from the standby database.
