tablespace 只能在CDB中操作。PDB 的中defaulttablespace 和 default temporary tablespace有两种修改方法(1) 使用ALTER PLUGGABLE DATABASE命令推荐使用这种方法法语如下ALTER PLUGGABLE DATABASE DEFAULT TABLESPACEusers;ALTER PLUGGABLE DATABASE DEFAULT TEMPORARYTABLESPACE temp;(2)为了向后的兼容性也可以使用ALTERDATABASE 命令修改ALTER DATABASE DEFAULT TABLESPACE users;ALTER DATABASE DEFAULT TEMPORARY TABLESPACEtemp;注意不管使用哪种方法在修改之前主要要保证container是正确的。--------------------------------------------------------------------------------------------版权所有文章禁止转载否则追究法律责任!AboutDave:QQ: 251097186Dave
