I have scheduled tasks from Toad being fired by Windows but nothing is happening. For example, I scheduled my materialize views to refresh everyday at mid night. The next morning, I see that there was a "Last Run Time" record in the Scheduled Tasks window but when I checked the materialize view against the original table, the data is different. The materialize view was not sync with the original table.
If the Scheduled Tasks window does record the scheduled Toad task being launched, then it is likely that the option "Save passwords" is not checked in the Connection Manager of Toad. So, when Windows automatically launches Toad, it cannot login. Hence, it records a launch time but it did nothing. Check you Connection Manager to make sure the "Save passwords" option is checked.
