PS:oracle可管理的最大数据块为2的22次方个，而根据单个数据块大小大小的不同，其最大容量也是不同的。对于OLTP应用，数据块的大小通常为8K，这样，算下来，单个数据文件的大小最大为(2^22)*8K=32G. 
既使指定“不限制”，其最大空间也是不能超过可管理最大空间的上限的。

修改表空间数据文件大小为不限制的语句为： 
alter database datafile ‘/oradata/orcl/demo01.dbf’ autoextend on maxsize unlimited;

创建表空间数据文件大小为不限制的语句为： 
create tablespace demo2 datafile ‘/oradata/orcl/demo201.dbf’ size 10M autoextend on maxsize unlimited;

所以只能 
增加表空间 
新增文件

SQL> alter tablespace SYSTEM add datafile '/data/app/oracle/oradata/orcl11g/system02.dbf' size 30000M autoextend on next 50M maxsize unlimited;

SQL> alter tablespace USERS add datafile '/data/app/oracle/oradata/orcl11g/users02.dbf' size 30000M autoextend on next 50M maxsize unlimited;

注意路径正确 有权限写入

再查表空间 已经新增了

SQL>  SELECT tablespace_name 表空间,sum(blocks*8192/1000000) 剩余空间M FROM dba_free_space GROUP BY tablespace_name;

表空间                                                        剩余空间M
