Recover databases synchronized with CDC

Question

Hi,
I need to define a mechanism with RMAN to backup two databases where information is copied from one to another by using Oracle Data Integrator CDC.
How can I backup and recover both databases and it still sync?
Thanks
Homero

HI Doug,
I think I figured out what causes the error here.
You are using a parallel medium for backup and restore.
When you start the recovery e.g. via db_activate recover <MEDIUM NAME> you get a reply from the dbm server as soon as the first data stream has been completely  read.
And since (obviously) not all of the parallel data streams (could be files, could be pipes) can be finished at the exact same point in time, there will always be pages left to be read when the first stream is done.
That's exactly what the -8020 message tells you here.
It says "Hey, the first data stream is done and there is still more to be read".
But - you already started the other streams since they are part of the parallel medium.
So there is no need at all to manually add them with recover_replace.
Instead all you've to do is to wait until the rest of the data is processed.
To tell the dbm server this the command [recover_ignore|http://maxdb.sap.com/doc/7_6/30/f7c7e35be311d4aa1500a0c9430730/content.htm] is used.
Even more comfortable would be to use the AUTOIGNORE flag when starting the recovery.
Finally, the best option would be not to perform the recovery via DBMCLI at all.
Use the GUI tools. They have all the knowledge build in. They are simple and easy to use and give you all the options that you have with DBMCLI.
