Hi Prasad, Thanks for the reply. I have added one more datasource with <xa-datasource>. But there is a problem. When i add the data to the database through my application, the data is added/updated only in first datasource. The second database is not updated. I mean the distributed insertion / update is not happening. Can you suggest me if i need to do any other settings?
