oracle资料库还原段和TEMP表空间满了各对业务会有什么影响？ 1、Oracle如果UNDO（撤销）表空间满了，直接导致DML操作等待UNDO释放空间。2、Oracle如果TEMP满了会出现两种情况：a. 出现ORA-1652 unable to extend temp segment by 256 in tablespace错误，回滚事务。b. ORACLE会提早重用temp空间，可能对...

Oracle的算法应该更加科学点,不过可以先这么理解,总之排序分页环境下temp消耗是有限的,大家可以手动创建一个非常小的temp tablespace关闭自动扩展,构造一个亿数量级的大表来排序,但是只取其中的前10行数据,看是否temp报出空间不足,也可以用gather_plan_statistics来查看SQL实际的运行的temp资源消耗等方法都可以验证。
