Oracle修改表空间大小的方法
本文讲述了Oracle修改表空间大小的方法。分享给大家供大家参考，具体如下：1）查看各表空间分配情况
SQL> select tablespace_name, sum(bytes) / 1024 / 1024 from dba_data_files group by tablespace_name;
TABLESPACE_NAME SUM(BYTES)/1024/1024
------------------------------ --------------------
UNDOTBS1 100
SYSAUX 530
USERS 5
SYSTEM 700
EXAMPLE 100
5 rows selected
2）查看各表空间空闲情况
SQL> select tablespace_name, sum(bytes) / 1024 / 1024 from dba_free_space group by tablespace_name;
TABLESPACE_NAME SUM(BYTES)/1024/1024
------------------------------ --------------------
SYSAUX 26.125
UNDOTBS1 69.6875
USERS 0.9375
SYSTEM 1.1875
EXAMPLE 21.25

3）更改数据表大小(10G)
alter database datafile '/ora/oradata/radius/testNS.dbf' resize 10240m;
