Como desabilitar a publicação e a distribuição (Programação RMO)
Você pode desabilitar a publicação e a distribuição de forma programada, usando o RMO (Replication Management Objects).
Para desabilitar a publicação e a distribuição
Remova todas as assinaturas das publicações que usam o Distribuidor. Para obter mais informações, consulte Como excluir uma assinatura pull (Programação RMO) e Como excluir uma assinatura push (Programação RMO).
Se o Publicador e o Distribuidor estiverem no mesmo servidor, remova todas as publicações que usam o Distribuidor e desabilite a publicação em todos os bancos de dados. Para obter mais informações, consulte Como excluir uma publicação (Programação RMO).
Crie uma conexão com o Distribuidor usando a classe Serverconnection.
Crie uma instância da classe DistributionPublisher. Especifique a propriedade name()()()() e passe o objeto ServerConnection da etapa 3.
(Opcional) Chame o método LoadProperties para obter as propriedades do objeto e para verificar se o Publicador existe. Se esse método retornar false, o nome do Publicador definido na etapa 4 estava incorreto ou o Publicador não está sendo usado pelo Distribuidor.
Chame o método Remove(Boolean). Passe um valor de true para force caso o Publicador e o Distribuidor estejam em servidores diferentes, e quando o Publicador tiver de ser desinstalado no Distribuidor, sem verificar primeiro se não há publicações no Publicador.
Crie uma instância da classe ReplicationServer. Passe o objeto ServerConnection da etapa 3.
Chame o método UninstallDistributor. Passe um valor de true para a force para remover todos os objetos de replicação no Distribuidor sem verificar primeiro se todos os bancos de dados de publicação locais foram desabilitados e os bancos de dados de distribuição desinstalados.
Exemplo
Esse exemplo remove o registro do Publicador no Distribuidor, descarta o banco de dados de distribuição e desinstala o Distribuidor.
