Avoir un problème avec les notifications d'événements. Sur la machine / le lecteur / la base de données à laquelle les messages sont envoyés (récepteur), le lecteur s'est rempli lorsque personne ne regardait, il a donc été sauvegardé toute la journée.
Maintenant que nous avons libéré de l'espace sur le lecteur, il accepte les messages dans la file d'attente, mais il ne semble pas les traiter - aucun nouvel enregistrement inséré, même si la file d'attente compte maintenant 22 millions de messages et augmente (!). La file d'attente EST activée:
is_activation_enabled = 1
is_receive_enabled = 1
is_enqueue_enabled = 1Je vois le SP activé activation_procedure, mais quand je regarde dedans SP_WHOISACTIVE, je ne vois aucun lecteur actif.
Avant de souffler à nouveau sur le lecteur - que fais-je de mal? Comment puis-je le faire traiter ou vider les messages? Merci d'avance.
Mise à jour
Une pensée - depuis que je l'ai is_enqueue_enabled, peut-être qu'il stocke tous les messages jusqu'à ce qu'il puisse les traiter tous? Si oui, puis-je désactiver cela en toute sécurité?

-- 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.

Pour les points de terminaison tcp, des deux côtés, considérez le service acct utilisé et la permission de connexion - ré-octroi, puis nouveau démarrage sur les points de terminaison -> même si gui ou dmv dit démarré.
