在执行一个业务数据库迁移的时候发现导入报告如下错误，常识几次都不能正常执行导入操作。
数据在其他库中导出时使用默认导出dmp包，但在导入到本机时提示如下问题。

通过提示信息发现导入时报告ora-01659报错。
oracle官网解释如下
ORA-01659: unable to allocate MINEXTENTS beyond string in tablespace string
Cause: Failed to find sufficient contiguous space to allocate MINEXTENTS for the segment being created.
Action: Use ALTER TABLESPACE ADD DATAFILE to add additional space to the tablespace or retry with smaller value for MINEXTENTS, NEXT or PCTINCREASE

在exp时，如果不加compress=no，那么那些个建表语句就会将他的initial空间指定为现有所有数据空间之和，这也是为了导入的时候空间连续，减少碎片的。加上那个参数再次导出，ini空间不会那么大。这个时候导入不再报上面的错误信息，问题解决！
