查看临时表分区

SELECT *
  FROM (SELECT USERNAME,
               SESSION_ADDR,
               SQL_ID,
               CONTENTS,
               SEGTYPE,

          FROM V$SORT_USAGE
         ORDER BY BLOCKS DESC)
 WHERE ROWNUM <= 200;

查看表空间使用率

SELECT a.tablespace_name "表空间名称", 

total / (1024 * 1024) "表空间大小(M)", 

free / (1024 * 1024) "表空间剩余大小(M)", 

(total - free) / (1024 * 1024 ) "表空间使用大小(M)", 

total / (1024 * 1024 * 1024) "表空间大小(G)", 

free / (1024 * 1024 * 1024) "表空间剩余大小(G)", 

(total - free) / (1024 * 1024 * 1024) "表空间使用大小(G)", 

round((total - free) / total, 4) * 100 "使用率 %" 

FROM (SELECT tablespace_name, SUM(bytes) free 

FROM dba_free_space 

GROUP BY tablespace_name) a, 

(SELECT tablespace_name, SUM(bytes) total 

FROM dba_data_files 

GROUP BY tablespace_name) b 

WHERE a.tablespace_name = b.tablespace_name

1.查看临时表空间的数据文件及存放路径
select tablespace_name,
file_name,
user_bytes/bytes,
bytes / 1024 / 1024 "file_size(M)",
autoextensible
from dba_temp_files t
where t.TABLESPACE_NAME = 'TEMP';

 

 2.

登录数据库服务器，执行扩容语句，如下

SQL> alter database tempfile '/u01/app/oracle/oradata/orcl/temp01.dbf' resize 4G;
