计算机术语“chained block”的中英文意思、释义、翻译及用法-计算机英汉双解词典

术语	chained block
释义	chained block 链接块 A second or subsequent ORACLE block designated to store table data, when the originally allocated block has run out of space and rows in that block expand due to updates. More often used for table data, but index data can also be chained. More chained blocks will have impact on performance, so if they occur, the PCTFREE space definition parameter may be set too low. 当原先分配的块已用完而在该块中的行要扩大进行修改时,为存储列表数据而设计的第二或后续的ORACLE块。常用于列表数据,但索引数据也可以被链接。过多的链接块会影响性能,所以如果出现这种情况,则可能是PCTFREE空间的定义参数设置得过低了。
