When the connection to the primary DB2 server fails, DB2 will retrieve the alternate server information from memory and will use that alternate server information to connect to the right DB2 server.
如果到主要DB 2服务器的连接失败,DB 2将从内存中检索备用服务器信息,并将使用该备用服务器信息连接到正确的DB 2服务器。
This helps server applications to compute the memory requirements in advance and hence increased performance.
这有助于服务器应用程序预先计算内存需求并因此而提高性能。
