一、查询表空间常规语句

1.查询表空间使用情况

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、查询表空间的free space

select tablespace_name, count(*) AS extends,round(sum(bytes) / 1024 / 1024, 2) AS MB,sum(blocks) AS blocks from dba_free_space group BY tablespace_name;

3、查询表空间的总容量

select tablespace_name, sum(bytes) / 1024 / 1024 as MB from dba_data_files group by tablespace_name;

--查询表空间使用率

SELECT total.tablespace_name,

Round(total.MB, 2) AS Total_MB,

Round(total.MB - free.MB, 2) AS Used_MB,

Round(( 1 - free.MB / total.MB ) * 100, 2)

|| '%' AS Used_Pct

FROM (SELECT tablespace_name,

Sum(bytes) / 1024 / 1024 AS MB

FROM dba_free_space

GROUP BY tablespace_name) free,

(SELECT tablespace_name,

Sum(bytes) / 1024 / 1024 AS MB

FROM dba_data_files

GROUP BY tablespace_name) total

WHERE free.tablespace_name = total.tablespace_name;

二、解决表空间满实例

1、20160613处理ydjc表空间满，处理情况

1）查询表空间使用效率

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）查询文件：

SELECT * FROM dba_data_files d WHERE d.TABLESPACE_NAME='TBS_MASTER'

3）执行增加数据文件

ALTER TABLESPACE TBS_MASTER ADD DATAFILE '+DATA_ASM/ipsd/tbs_master16.dbf' SIZE 1G AUTOEXTEND ON NEXT 10M MAXSIZE unlimited

2、20160921处理临时表空间不足问题：

--新增临时表空间

SELECT * FROM dba_TEMP_files d WHERE d.TABLESPACE_NAME='TEMP';

--新增临时表空间

ALTER TABLESPACE TEMP ADD TEMPFILE '/data/devgbk/devgbk/temp02.dbf' SIZE 1G AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;

SELECT D.*,D.USER_BYTES/D.BYTES FROM dba_TEMP_files d WHERE d.TABLESPACE_NAME='TEMP';

--修改已经临时表空间大小

ALTER DATABASE TEMPFIle '+DATA_ASM/ipsd/temp03.dbf' RESIZE 20G;
