A comparação de esquema SSDT falha ao comparar meu projeto de banco de dados com o servidor do Azure

12

Eu tenho um projeto de banco de dados SQL no qual construí nosso banco de dados corporativo. Ele foi implantado várias vezes em servidores SQL internos e hospedados pela AWS, usando a ferramenta Comparação de Esquema do SSDT.

O problema ao postar no Azure Hosted Win 2012 Server executando o SQL Ent 2012 sp2. Ele volta com "Comparação concluída. Nenhuma diferença detectada".

Eu sei que isso está errado, porque eu posso abrir o Enterprise Manager e comparar o esquema com o Projeto SQL e ver que há uma diferença.

Encontrei vários artigos falando sobre como o lançamento de 2014 quebrou a ferramenta, mas esses apresentavam diferenças de versão.

[Sim, eu fiz isso no Google. Afirmando que sou notório por esquecer de fazê-lo. ] https://www.google.com/webhp?ie=utf-8&oe=utf-8#q=ssdt+data+compare+fail+to+detect+difference&start=10

Outras coisas que verifiquei incluem garantir que minha conta do banco de dados tenha acesso ilimitado. Eu posso me conectar ao console de gerenciamento. Eu posso me conectar com programas locais.

Última confirmação de que houve um problema:

  1. Eu criei um SP que possui um único retorno do número 1.
    1. Poderia ter um retorno de nada por causa dos testes.
  2. Depois de criar o SP, executei a comparação de esquemas em todas as minhas instâncias e todas, exceto o servidor do Azure, mostraram a variação.

Atualizar

Eu verifiquei que isso é explicitamente com o servidor, pois agora dois usuários diferentes em dois computadores diferentes estão tendo o mesmo problema exato.

TL; DR

A consulta que o Visual Studio está executando está sendo bloqueada e a consulta atinge o tempo limite.


Acontece que eu consegui resolver isso para a nossa situação: tempo limite devido ao bloqueio!

Executei um rastreamento de criador de perfil com um filtro no nome do aplicativo do Microsoft SQL Server Data Tools, Comparação de esquemas para capturar os eventos de comparação de esquema do Visual Studio.

Atingiria uma determinada consulta e depois pararia, quando o VS alegaria que a comparação estava concluída.

Aqui está o lote de consultas em questão:

A execução da consulta no SSMS nunca terminaria a execução no servidor incorreto, mas levaria menos de um segundo em todos os outros ambientes.

Então comecei a separá-lo e descobri que as consultas que estavam lendo das três visualizações do sistema a seguir eram o problema:

  • sys.server_event_session_actions
  • sys.server_event_session_events
  • sys.server_event_session_fields

A primeira dessas exibições de sistema continha apenas 28 registros (encontrados ao executar a Count(*)), mas não retornaria os dados a menos que eu usasse a (NOLOCK)dica ... [b] problema de bloqueio !

Descobrir a cabeça da cadeia de bloqueio foi fácil, mas não era passível de matança, pois era uma sessão de Eventos Estendidos. Há uma correção para esse problema aqui: https://support.microsoft.com/en-gb/kb/2511963

Mas espero que, no seu caso, você possa simplesmente matar a cabeça da corrente e retornar as coisas ao normal!


EDIT: Tendo agora uma janela de manutenção viável para o SQL Server afetado, uma reinicialização limpou o SPID e agora as comparações estão funcionando mais uma vez!

Além disso, aqui está um script rápido que escrevi para encontrar o chefe da (s) cadeia (s) de bloqueio que pode ser útil para futuros leitores: http://gvee.co.uk/files/sql/admin.blocking_chains.sql
