DMVs do SQL Server disponíveis no pool de SQL dedicado (antigo SQL DW)

O pool de SQL dedicado (antigo SQL DW) expõe muitas das exibições de gerenciamento dinâmico do SQL Server (DMVs). Essas exibições, quando consultadas no pool de SQL dedicado (antigo SQL DW), estão reportando o estado dos Bancos de Dados SQL em execução nas distribuições.

O pool de SQL dedicado (antigo SQL DW) e o Parallel Data Warehouse (PDW) usam as mesmas exibições do sistema. Cada DMV tem uma coluna chamada pdw_node_id, que é o identificador do nó de Computação.

Observação

Para usar essas exibições, insira “pdw_nodes_” no nome, conforme mostrado na seguinte tabela:
