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;
