Problem z powiadomieniami o zdarzeniach. Na komputerze / dysku / bazie danych, do których wysyłane są wiadomości (odbiornik), dysk zapełnił się, gdy nikt go nie szukał, więc kopia zapasowa jest tworzona przez cały dzień.
Teraz, gdy zwolniliśmy miejsce na dysku, przyjmuje on wiadomości do kolejki, ale wydaje się, że nie przetwarza ich - nie wstawiono żadnych nowych rekordów, mimo że kolejka ma teraz 22 miliony wiadomości i rośnie (!). Kolejka jest włączona:
is_activation_enabled = 1
is_receive_enabled = 1
is_enqueue_enabled = 1Widzę aktywowany SP activation_procedure, ale kiedy zaglądam SP_WHOISACTIVE, nie widzę aktywnych czytników.
Zanim ponownie wysadzę dysk - co robię źle? Jak mogę go przetworzyć lub opróżnić wiadomości? Z góry dziękuję.
Aktualizacja
Jedna myśl - skoro mam is_enqueue_enabled, może przechowuje wszystkie wiadomości, dopóki nie przetworzy ich wszystkich? Jeśli tak, czy mogę to bezpiecznie wyłączyć?

-- With apologies and thanks to Remus Rusanu, Jonathon Kehayias, Mladen Prajdic, and Jasper Smith for writing
-- about EN, answering questions, and getting the word out about this awesome feature of SQL Server 2005+.
-- Also thanks to Mikael Eriksson for a faster parse with the XML filter.
-- Their code modified, combined, and used below. Any errors herein are mine, not theirs.
-- Part of the code came from MVP Deep Dives Vol 1 Chapter 28 (Mladen), PASS Presentations by Jasper and Jonathon,

--History: 1.00 2012/08/27 first release
-- 1.01 2012/09/05 added server-based exclusions and eventsubclass = 0
-- 1.1 2012/09/17 added exclusion_sets which allow multi-condition filtering and improved performance
-- 1.11 2012/10/05 removing the 1=1 as per suggestion by Rusanu;
-- this could cause it to spin forever, blowing out the error_log..and the drive.
-- 1.12 2012/11/14 adding a RETURN in the @@ROWCOUNT. It fails to exit and then hits a COMMIT, causing records
-- in enaudit_error. That was due to the 1.11 change where I no longer use a 1=1.
-- 1.13 2014/01/16 changing ERRORLOG to write the first 500 chars to the CommandText field, as tested in Canada.

W przypadku punktów końcowych TCP, obie strony, rozważ użyty acct usługi i połącz uprawnienia - spróbuj ponownie przyznać, a następnie nowy start w punktach końcowych -> nawet jeśli GUI lub DMV mówi, że zostało uruchomione.
