------解决方案--------------------
从Oracle的Reference文档里面摘录的，基本上就是标识一些系统资源的使用、设置情况的。
current_utilization - Number of (resources, locks, or processes) currently
being used
max_utization - Maximum consumption of the resource since the last
instance start up
initial_allocation - Initial allocation. This will be equal to the value
specified for the resource in the initialization parameter
file (UNLIMITED for infinite allocation)
limit_value - Unlimited for resources and locks. This can be greater
than the initial allocation value (UNLIMITED for infinite
limit).
