oracle 增加表空间

1、表空间使用情况

  SELECT UPPER(F.TABLESPACE_NAME) "表空间名",
  D.TOT_GROOTTE_MB "表空间大小(M)",
  D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(M)",
  TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) / D.TOT_GROOTTE_MB * 100,2),'990.99') || '%' "使用比",
  F.TOTAL_BYTES "空闲空间(M)",
  F.MAX_BYTES "最大块(M)"
  FROM (SELECT TABLESPACE_NAME,
  ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,
  ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES
  FROM SYS.DBA_FREE_SPACE
  GROUP BY TABLESPACE_NAME) F,
  (SELECT DD.TABLESPACE_NAME,
   ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB
  FROM SYS.DBA_DATA_FILES DD
  GROUP BY DD.TABLESPACE_NAME) D
  WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME
  ORDER BY 1;

2、表空间地址

select * from dba_data_files where tablespace_name='JSDT_DATA';

3、

增加表空间文件

alter tablespace JSDT_DATA add datafile '/home/oracle/app/product/11.2/db/dbs/homeoracleapporadatadtposJSDT_DATA4.dbg' size 20480M autoextend off;

4、查看表空间表格使用情况

select segment_name,bytes/1024/1024 from dba_segments where tablespace_name
='JSDT_DATA' and segment_type='TABLE';
