Deployed data rules have lost data source connection

[infodfs]

Hi,
I have deployed two projects from development to testing environment. All the data rules deployed in testing environment have lost data source connection. When I run the rules, they stopped right way, without showing in Infosphere Director. To resolve this issue, I have to drop the data source and add them back to the project properties manually. We have used replacing commands to deploy, but still getting this data source disconnection issue. Data source configuration is consistent between these two environments. Is there anyone could help to resolve this issue? Thanks in advance.

Search (e.g. Fix Central) or ask your support provider whether this is a known issue for your exact version. I'm not aware of any such behaviour, but I'm not currently using Data Rules.
