工作总结30 ORACLE表空间无法扩展后处理

 --查看表空间使用情况

select  t1 "表空间" , 

        z/(1024*1024*1024) "总表空间",
z-s/(1024*1024*1024) "已用表空间",
s/(1024*1024*1024) "剩余表空间",

        ROUND((z-s)/z*100,2)  "使用率%"

from (select tablespace_name t1, sum(bytes) s

      from dba_free_space group by tablespace_name),

     (select tablespace_name t2, sum(bytes) z

      from dba_data_files 

      group by tablespace_name) where t1 = t2

--查询表空间的数据文件

select  file_name,tablespace_name,bytes,autoextensible,maxbytes from

dba_data_files where tablespace_name='USERS'

--初始化表空间大小

alter tablespace USERS add datafile 'D:\ORACLE\PRODUCT\10.2.0\DB_1\ORADATA\ORCL\USERS02.DBF'

size 1024m autoextend on next 200m maxsize unlimited;

--可以调整表空间扩展大小

alter database datafile 'D:\ORACLE\PRODUCT\10.2.0\DB_1\ORADATA\ORCL\USERS02.DBF' autoextend on next 200m maxsize unlimited;
