Hi all,

Today I see my system tablespace is 98%, 480 MB used. Why the system tablespace is so big? What should I do at this situation?

Thanks for helps.

Query DBA_SEGMENTS to know which take the space.

First check there is no user objects in it.
Then check SYS.AUD$ table maybe you have an audit activated and never purge the audit trail.

first see what objects (and what size) are there ....

SELECT   segment_name, segment_type, owner, BYTES
    FROM dba_segments
   WHERE tablespace_name = 'SYSTEM'
ORDER BY BYTES DESC;

sorry for duplicate answer. my link is slow.

I think you should increase your system tablespace size .
and
just make sure that non sys or system user objects are not here.

You have many procedure/package codes.
The only thing you can do is increased the size of your SYSTEM tablespace (which seems very low, it should be at least 500M for a test database).
