Apply not working in down stream environment after upgrading databases from 10.2.0.4 to 11.2.0.3

Hi,

I recently upgraded 2 databases from 10.2.0.4 to 11.2.0.3 on Windows 64-bit platform. The databases were running a downstream  environment with schema replication from source to target, with capture/apply processes running on target.

What I did was disabling capture/apply first, upgrading the databases (target first) using DBUA and enable capture/apply after successfull upgrade. No errors are thrown, but it seems that changes in source are not applied on target.

Are there any other steps required when upgrading from 10.2 to 11.2 ?  I see that Streams is running 'combined capture and apply' after upgrade...?

Thanks

Rolf
