PL SQL create tablespace
create tablespace KInfoData
datafile 'f:\KSSData\KInfoData01.ora' size 100M REUSE,'f:\KSSData\KInfoData02.ora' size 100M REUSE
DEFAULT STORAGE(INITIAL 500K NEXT 500K PCTINCREASE 20);
想问其中的size 100M 是tablespace kInfoData 的空间大小吗,如果以后随着表的增多,100M可以改变吗,REUSE和 PCTINCREASE 20是什么意思.
-----------------------------------------
可以改，也可以再增加一个100M的数据文件。
下一个next值的百分比率。
-----------------------------------------------
一个表空间可以包含多个数据文件并且数据文件可以分别在不同的物理磁盘上,这样做是为了平衡I/O.
以后还是可以说表空间的大小,不用说数据文件大小.因为表空间是数据文件在逻辑上的集合.
