One of our Informatica developers is getting the following error while running a workflow.
First Error Code: 36401
Session Task instance: "s_test_output_cubes": Execution terminated unexpectedly.
This is a session that was working until yesterday. What may have caused the problem. Please help.
It sounds like it was caused by something that was happening on the Server box itself while the session was running. Check the PC Server logs if it happens again. If the error had happened relative to the mapping or the session specs, you would have received a more specific message.
Disconnect and reconnect the repository.check all your sesssion DB connections and integration services connection ,still your facing any issue ,contact your informatica server admin team .
