Agent Builder 将创建以下扩展属性，这些属性对于大多数数据服务来说都有用。

Confdir_list

指定应用程序配置目录的路径，这对于很多应用程序是有用的信息。当群集管理员对数据服务进行配置时，可以提供该目录的位置。

Monitor_retry_count、Monitor_retry_interval 和 Probe_timeout

控制故障监视器本身的重新启动操作，而非服务器守护进程。

Child_mon_level

设置 PMF 要执行的监视级别。有关更多信息，请参见 pmfadm(1M) 手册页。

您可以在由 User added code 注释分界的区域内创建其他扩展属性。
