Hi Lalu,
How do you end to create your Oracle connections (both, primary and replicate), using "profile" option?
This latest error seems to be reported from your "Primary" connection, for your source Oracle server.
You may have to create this primary connection using "with [log transfer on,] dsi_suspended" option(s) or suspend the DSI using "suspend connection to SOURCEORA.SOURCEORA" now.
For Primary "Oracle" connection, the DSI must be (usually) kept "suspended".
Regards
Yvan
