在主要计算机或备用计算机上启动DB 2 HADR之前，正确设置所有HADR参数的值非常重要。
It is critical that all the HADR parameters be set with proper values prior to starting DB2 HADR on either the primary or standby machine.
给主和备用数据库的HADR配置参数设置适当的值。
Assign appropriate values to the HADR configuration parameters for both the primary and the standby database.
但与获取数据时不同的是，在备用存储不可用，或有些东西尚未保存时您必须提供缺省值。
One difference with getting, though, is that you must provide a default value in the event that the backing store is unavailable, or for when something hasn't been saved yet.
