4、扩展临时表空间：

--方法一、增大临时文件大小：
SQL> alter database tempfile ‘/u01/app/oracle/oradata/orcl/temp01.dbf’ resize 100m;
--方法二、将临时数据文件设为自动扩展：
SQL> alter database tempfile ‘/u01/app/oracle/oradata/orcl/temp01.dbf’ autoextend on next 5m maxsize unlimited;
--方法三、向临时表空间中添加数据文件：
SQL> alter tablespace temp add tempfile ‘/u01/app/oracle/oradata/orcl/temp02.dbf’ size 100m AUTOEXTEND ON NEXT 1G MAXSIZE 10g; 

alter tablespace temp add tempfile ‘/u01/app/oracle/oradata/orcl/temp02.dbf’ size 100m AUTOEXTEND ON NEXT 1G MAXSIZE 32g;

alter tablespace <tablespace_name> add datafile ‘/u01/app/oracle/oradata/orcl/temp02.dbf’ size 4096m AUTOEXTEND ON NEXT 1G;

//FOR RAC

alter tablespace temp add tempfile '+NEW_DATA' size 5m AUTOEXTEND OFF;

alter database tempfile '+NEW_DATA/FULLPATH' resize 200m;

 查看文件可扩展性

select file_name,autoextensible from dba_data_files where tablespace_name = 'UNDOTBS1';

select df.tablespace_name,df.autoextensible from dba_temp_files df where df.autoextensible='NO';

3.拼接成一句话查询表空间的方法，这里考虑到 表空间可以扩展到的最大空间（maxbytes）,而不是当前大小(current bytes)

SELECT TRIM(DBMS_LOB.SUBSTR(WM_CONCAT(DATAVAL))) VALUE
FROM (SELECT 'CNT=' || MAX(FLAG) AS DATAVAL
FROM (SELECT '0' FLAG
FROM (SELECT a.tablespace_name
FROM (SELECT tablespace_name, SUM(bytes) free
FROM dba_free_space
GROUP BY tablespace_name) a,
(SELECT tablespace_name,
SUM(CASE autoextensible
WHEN 'YES' THEN
maxbytes
ELSE
bytes
END) maxbytes,
SUM(bytes) total
FROM dba_data_files
GROUP BY tablespace_name) b
WHERE a.tablespace_name = b.tablespace_name
and b.tablespace_name NOT IN
('UNDOTBS1', 'UNDOTBS2')
and round((total - free) / b.maxbytes, 4) * 100 < 90)
UNION ALL
SELECT '1' FLAG
FROM (SELECT a.tablespace_name
FROM (SELECT tablespace_name, SUM(bytes) free
FROM dba_free_space
GROUP BY tablespace_name) a,
(SELECT tablespace_name,
SUM(CASE autoextensible
WHEN 'YES' THEN
maxbytes
ELSE
bytes
END) maxbytes,
SUM(bytes) total
FROM dba_data_files
GROUP BY tablespace_name) b
WHERE a.tablespace_name = b.tablespace_name
and b.tablespace_name NOT IN
('UNDOTBS1', 'UNDOTBS2')
and round((total - free) / b.maxbytes, 4) * 100 >= 90)
UNION ALL
SELECT '2' FLAG
FROM (SELECT a.tablespace_name
FROM (SELECT tablespace_name, SUM(bytes) free
FROM dba_free_space
GROUP BY tablespace_name) a,
(SELECT tablespace_name,
SUM(CASE autoextensible
WHEN 'YES' THEN
maxbytes
ELSE
bytes
END) maxbytes,
SUM(bytes) total
FROM dba_data_files
GROUP BY tablespace_name) b
WHERE a.tablespace_name = b.tablespace_name
and b.tablespace_name NOT IN
('UNDOTBS1', 'UNDOTBS2')
and round((total - free) / b.maxbytes, 4) * 100 >= 95))
UNION ALL
SELECT TRIM(DBMS_LOB.SUBSTR(WM_CONCAT(ABC))) DATAVAL
FROM (SELECT 'NAME=' || TABLESPACE_NAME || ':SUM=' || SUM_SPACE ||
':USED=' || USED_SPACE AS ABC
FROM (SELECT D.TABLESPACE_NAME,
SPACE SUM_SPACE,
BLOCKS SUM_BLOCKS,
SPACE - NVL(FREE_SPACE, 0) USED_SPACE
FROM (SELECT TABLESPACE_NAME,
ROUND(SUM(BYTES) / (1024 * 1024), 2) SPACE,
SUM(BLOCKS) BLOCKS
FROM DBA_DATA_FILES
GROUP BY TABLESPACE_NAME) D,
(SELECT TABLESPACE_NAME,
ROUND(SUM(BYTES) / (1024 * 1024), 2) FREE_SPACE
FROM DBA_FREE_SPACE
GROUP BY TABLESPACE_NAME) F
WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME(+)) A));

这个sql 文件如果执行的结果是cnt=0的话，应该表空间会小于90%。

 只有出现CNT=1,或者CNT=2的时候，才会出现这个报警。那就是表空间大于90%，或者大于95%。
