Did you check the other notes about this subject?
Such as;
Registering a New Integrated Extract Hangs In INITIALIZING State (Doc ID 2414184.1)
Oracle Capture in state "WAITING FOR TRANSACTION", excessive time spent in LOGMNR_DICT_CACHE.SAVE_OBJ() (Doc ID 2030973.1)
AS for your downstream related question;
When we talk about downstream replication; we actually have the following;
The source database ships its redo logs to a downstream database, and Extract uses the logmining server at the downstream database to mine the redo logs.
So, actually you use dataguard redo transport sevices to ship the redo from primary to downstream.
If you want to replace that shipment method, then we are talking about a complete picture.
I understand you right, right?
That is we will put a tool to make that redo shipment. That tool may be a custom log shipping script or a sophisticated tool that use log miner and get the changes from redo or archives of the primary and then transforms them (if necessary) and lastly apply them to the target.(downstream) .. A tool like Striim can do that.. But the complexity of the flow will increase so it may not be feasible to do that.
