Sometime it happens like Informatica session got failed but Workflow will show as succeeded. If you are running mappings though DAC , DAC will not stop execution as Workflow got succeeded. So in that case it is very difficult to find out the failed mappings. So to control the DAC and to get the actual status of mapping we need to enable a option , "Fail parent if this task failed" in session level.
Open session and enable the below showed options.
