After studying the questions of data allocation and tile declustering in heterogeneous disk systems, a same-rate virtual disk dividing method and a virtual disk sorting method are proposed.
着重讨论了异构磁盘系统的数据分配和瓦片分布问题,提出了一种速率均匀虚拟磁盘划分方法和一种虚拟磁盘排序方法。
For example, if there were an excessive amount of sorting such that the sort heap spilled to disk, performance would suffer.
比如说,如果出现大量排序操作,导致排序堆被溢出到磁盘上,那么性能就会受到影响。
Oracle automatically allocates this disk space called a temporary segment. Typically, Oracle requires a temporary segment as a database area for sorting.
临时表空间中的默认存储参数决定了临时段中区的分配原则。
