ORA-01653:表空间扩展失败的问题

----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 4 DESC;

表空间名                       表空间大小(M) 已使用空间(M) 使用比 空闲空间(M) 最大块(M)
------------------------------ ------------- ------------- ------- ----------- ----------
SYSTEM 560 555.37   99.17 4.63 3.94
SYSAUX 660 639.81   96.94 20.19 4.94
NEWBIL 16000 15196.62   94.98 803.38 261.94
UTAN 1600 1518.94   94.93 81.06 80.94

发现表空间只有4.63M的空闲,猜测可能是表空间自动扩展失败的问题(表空间的增长量太高,,Oracle默认是50%),修改表空间文件扩展方式:

---查看表空间是否具有自动扩展的能力---
------------------------------------------------------------------------------------------
SELECT T.TABLESPACE_NAME,D.FILE_NAME,  
D.AUTOEXTENSIBLE,D.BYTES/1024/1024/1024,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; 

---解决办法---
------------------------------------------------------------------------------------------
alter tablespace USERS
add datafile '/oracle/oradata/tianyi/users07.dbf'
size 10240M;
