When failing a sign-in (bad password) from Tableau Server to an Oracle data source, the failed sign-in counts towards the total tries for that user on the Oracle side, and at the same time seems to be incrementing the number of VizQL processes in the Tableau Server environment. This issue results in users getting locked out of the database after fewer tries than expected.

Refreshes for extracts based on multiple databases intermittently failed with the error "Internal Error - an unexpected error occurred and the operation could not be completed".
