2、DBMS_SPACE
这是另一个Oracle古老支持包，它的SPACE_USAGE存储过程提供关于BasicFile和SecureFile LOB的空间利用率，我在TRBTKT.PKG_SECUREFILES包中引入了两个存储过程：CALC_SPACE_BASICFILES和CALC_SPACE_SECUREFILES。但遗憾的是，这个功能只能在启用了自动段空间管理(ASSM)的表空间上使用，而且，它也不会考虑任何BasicFile LOB块的空间利用率，在清单5中，我对表TRBTKT.TICKETS和TRBTKT.SECURE_TICKETS分别调用了这些存储过程，并返回了相应的输出。
清单5 确定BasicFile和SecureFile LOB的空间利用率

许多公司都与Oracle有无限制授权协议，他们害怕离开这个协议，所以就证明他们在使用Oracle的软件，即使因为需求单独购买部分授权许可也可能总体是省钱的。
