Oracle表空间查看及扩展

• 根据表空间名称，查看表空间大小等情况

select tablespace_name, file_id, file_name, round(bytes/(1024*1024), 0) total_space from dba_data_files where tablespace_name = 'SYSAUX';

SELECT t.tablespace_name, round(sum(bytes/(1024*1024)), 0) ts_size from dba_tablespaces t, dba_data_files d where t.tablespace_name = d.tablespace_name and t.tablespace_name = 'SYSAUX' group by t.tablespace_name;

查看剩余空间

select sum(bytes) / (1024*1024) as free_space,tablespace_name from dba_free_space where tablespace_name ='SYSAUX' group by tablespace_name;

查看使用 和 剩余量

select a.tablespace_name, a.bytes total, b.bytes used, c.bytes free, round((b.bytes*100)/a.bytes, 2) "% used",
round((c.bytes * 100) / a.bytes, 2) "% free" 
 from sys.sm$ts_avail a, sys.sm$ts_used b, sys.sm$ts_free c where a.tablespace_name = b.tablespace_name and a.tablespace_name = c.tablespace_name and a.tablespace_name = 'SYSAUX';

• 为SYSAUX表空间增加数据文件

alter tablespace SYSAUX add datafile 'D:\APP\ZSDORACLE\ORADATA\ORCL\SYSAUX_20180502.DBF' SIZE 1G AUTOEXTEND ON NEXT 200M MAXSIZE UNLIMITED;

其中：表空间名称、路径地址、初始文件大小等参数根据自身情况去定义。

检查结果

select tablespace_name,file_name,autoextensible from dba_data_files where tablespace_name = 'SYSAUX';
