查看系统空间表使用情况

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 4 DESC;

设置空间表自增

alter tablespace SYSTEM add datafile '/home/u01/app/oracle/oradata/kfybjk/system02.dbf' size 30000M autoextend on next 50M maxsize unlimited;

查看空间表大小

SELECT T.TABLESPACE_NAME,D.FILE_NAME,D.AUTOEXTENSIBLE,D.BYTES,D.MAXBYTES,D.STATUS FROM DBA_TABLESPACES T,DBA_DATA_FILES D WHERE T.TABLESPACE_NAME =D.TABLESPACE_NAME ORDER BY TABLESPACE_NAME,FILE_NAME;

给空间表添加新的文件

alter tablespace USERS add datafile '/home/u01/app/oracle/oradata/kfybjk/users02.dbf' size 30000M autoextend on next 50M maxsize unlimited;

alter tablespace SYSTEM add datafile '/home/u01/app/oracle/oradata/kfybjk/system02.dbf' size 30000M autoextend on next 50M maxsize unlimited;

查看空间表剩余空间

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