oracle 查看临时表空间temp 的使用情况以及扩展表空间

SELECT D.TABLESPACE_NAME,SPACE "SUM_SPACE(M)",BLOCKS SUM_BLOCKS, 
USED_SPACE "USED_SPACE(M)",ROUND(NVL(USED_SPACE,0)/SPACE*100,2) "USED_RATE(%)",
NVL(FREE_SPACE,0) "FREE_SPACE(M)"
FROM 
(SELECT TABLESPACE_NAME,ROUND(SUM(BYTES)/(1024*1024),2) SPACE,SUM(BLOCKS) BLOCKS
FROM DBA_TEMP_FILES
GROUP BY TABLESPACE_NAME) D,
(SELECT TABLESPACE_NAME,ROUND(SUM(BYTES_USED)/(1024*1024),2) USED_SPACE,
ROUND(SUM(BYTES_FREE)/(1024*1024),2) FREE_SPACE
FROM V$TEMP_SPACE_HEADER
GROUP BY TABLESPACE_NAME) F
WHERE  D.TABLESPACE_NAME = F.TABLESPACE_NAME(+)

1 为空间不足的表空间增加数据文件
ALTER TABLESPACE &tablespace_name ADD DATAFILE '&datafile_name' SIZE 2G;
2 如果要为临时表空间扩容，使用下面的语句
ALTER TABLESPACE &tablespace_name ADD TEMPFILE '&datafile_name' SIZE 2G;
