We have a SQL Job agent which consists of several SSIS packages and in each package, it contains multiple sequences running concurrently.
The problem we have is the Job Agent would fail but at different step each time. However, if we run the failed package on its own, it would execute successfully.
The error message we get is "Login failed for user". In all these SSIS packages, we are using the same account credentials. It is weird that we run all SSIS packages in visual studio without any issue, however, some would fail once we execute them by a SQL job agent.
Does anyone know of any resolution to this problem?
Your idea would be appreciated. Thanks.
