Very early this morning:
Error message from the application users: They run a specific application against database1 via job and job failed.
Application users sent this following error message to DBAs:
DM-DBM-0400 UDA driver reported the following on connection database1:
UDA-SQL-0403 There are active transactions associated with the specified database.
How to troubleshoot? I checked: database and server both online. From activity monitor, no process on database1 at this moment.
