Comentários

Quando um Publicador é configurado com um Distribuidor remoto, os valores fornecidos para todas as propriedades, inclusive SnapshotGenerationAgentProcessSecurity, são enviados ao Distribuidor como texto sem-formatação. É necessário criptografar a conexão entre o Publicador e o respectivo Distribuidor remoto antes de chamar o método Create. Para obter mais informações, consulte Encrypting Connections to SQL Server.

O Create método só pode ser chamado por membros da sysadmin função de servidor fixa no Publicador ou por membros da db_owner função de banco de dados fixa no banco de dados de publicação.

Chamar o Create método é equivalente à execução de sp_addpublication (Transact-SQL) ou sp_addmergepublication (Transact-SQL).
