Processamento de Descarregamento do CDC

Processamento de Descarregamento do CDC

O processamento de descarregamento do CDC transfere o processamento de dados alterados de nível de coluna do Ouvinte do PowerExchange no sistema de origem para o cliente PowerExchange na máquina do Serviço de Integração do PowerCenter.
Para fontes de dados para as quais o PowerExchange usa o UOW Cleanser (UOWC), o processamento de descarregamento também transfere o processamento UOWC para a máquina do Serviço de Integração do PowerCenter. Essas fontes de dados incluem fontes de dados z/OS e fontes do Db2 for i (i5/OS).
Use o processamento de descarregamento quando os recursos do sistema de origem estiverem limitados. Nessa situação, o processamento de descarregamento pode ajudar a aumentar o rendimento das sessões do CDC.
