Oracle 中检查临时表空间的方法（oracle查看临时表空间剩余大小）不要告诉别人

目录一、什么是临时表空间二、oracle创建临时表空间的方法三、如何在 Oracle 中检查临时表空间3.1 如何检查 Temp 表空间的大小3.2 oracle如何查看临时表空间的可用空间3.3 如何在实例级别检查临时表空间使用情况3.4 如何查看 Temp 表空间的使用百分比3.5 如何找到正在使用临时表空间的会话3.5 如何通过会话检查临时使用情况3.6 如果我们还想看到正在运行的 sql3.7 如何使用大量 TEMP 查找会话四、oracle如何增加临时表空间4.1 如何调整临时文件的大小4.2 如何删除临时文件

–单个临时文件
CREATE TEMPORARY TABLESPACE TEMP TEMPFILE ‘/u01/oracle/TEST/oradata/temp_1.dbf’ SIZE 1000M;
–多个临时文件
CREATE TABLESPACE TEMP TEMPFILE
‘/u01/oracle/TEST/oradata/temp_1.dbf’ SIZE 1000M
‘/u01/oracle/TEST/oradata/temp_2.dbf’ SIZE 1000M
;
–使用 ASM
CREATE TEMPORARY TABLESPACE TEMP TEMPFILE ‘+DATA’ SIZE 1000M;

select tablespace_name,status,contents from dba_tablespaces where contents=’TEMPORARY’;

select file_name, tablespace_name, bytes from dba_temp_files
或
select a.name,b.name, a.bytes from v$tempfile a, v$tablespace b where a.ts#=b.ts#

select tablespace_name,sum(bytes)/1024/1024/1024 temp_gb
from dba_temp_files group by tablespace_name;
or
select b.name, sum(a.bytes)/1024/1024/1024 from v$tempfile a, v$tablespace b where a.ts#=b.ts# group by b.name;

select tsh.tablespace_name,
dtf.bytes/1024/1024/1024 total_GB,
sum(nvl(tsh.bytes_used,0))/1024/1024/1024 used_GB,
sum(nvl(tsh.bytes_free,0))/1024/1024/1024 free_GB,
(1-sum(nvl(tsh.bytes_free,0))/dtf.bytes)*100 pct,
from v$temp_space_header tsh,
(select tablespace_name, sum(bytes) bytes
from dba_temp_files
group by tablespace_name) dtf
where dtf.tablespace_name=tsh.tablespace_name(+)
group by tsh.tablespace_name, dtf.bytes/1024, dtf.bytes
order by 1
