Oracle:没有dba privs时如何检查表空间使用的空间 [英] Oracle: how to check space used by a tablespace when no dba privs

问题描述

我需要检查表空间使用的空间，但是我没有dba privs.有办法吗?

I need to check space used by a tablespace but I have no dba privs. Is there a way to do this?

推荐答案

不幸的是，没有对dba_free_space或dba_segments视图的显式权限，您将无法使用用户的默认表空间:

Unfortunately without explicit permissions to the dba_free_space or dba_segments views you are stuck with your users default tablespace:

SELECT
  ts.tablespace_name,
  TO_CHAR(SUM(NVL(fs.bytes,0))/1024/1024, '99,999,990.99') AS MB_FREE
FROM
  user_free_space fs,
  user_tablespaces ts,
  user_users us
WHERE
  fs.tablespace_name(+)   = ts.tablespace_name
AND ts.tablespace_name(+) = us.default_tablespace
GROUP BY
  ts.tablespace_name;

如果您需要检查没有用户的表空间的大小，将其作为默认表空间，则必须回到DBA.
使用系统表空间作为默认值进行测试:

使用应用程序表空间作为默认表空间进行测试:

此架构在dba视图上没有查询:

If you need to check the size of a tablespace for which you don't have a user with that as their default tablespace you're stuck with going back to your DBA.
Test with the system tablespace as default:

Test with an app tablespace as the default tablespace:

This schema does not have query on the dba views:

select * from dba_free_space;
ORA-00942: table or view does not exist
00942. 00000 -  "table or view does not exist"
*Cause:    
*Action:
Error at Line: 13 Column: 15
