Hello All,
The mgmt_tablespace is showing as full. What options do i have for freeing up space i.e. Is there a command i can ran to purge raw data etc?:

SQL> select TABLESPACE_NAME,BYTES/1024/1024 SIZE_MB, MAXBYTES/1024/1024 MAX_MB FROM dba_data_files;

TABLESPACE_NAME SIZE_MB MAX_MB
------------------------------ ---------- ----------
SYSTEM 2048 0
SYSAUX 2048 0
UNDOTBS 4096 4096
USERS 32 0
SYSAUD 128 256
MGMT_TABLESPACE 32767.9844 32767.9844
MGMT_AD4J_TS 4050 32767.9844
MGMT_ECM_DEPOT_TS 1500 32767.9844
MGMT_TABLESPACE 3072 0

Thanks,

You have to first clearly know what's inside the tablespace.

Your query does not show that the tablespace is full. It shows only that the one datafile of which it consists is at its maximum size. You need to query dba_free_space to determine if the tablespace is full.

hi John,
the mgmt_tablespace isn't in dba_free_space:

SQL> select distinct(TABLESPACE_NAME) from dba_free_space;

TABLESPACE_NAME
------------------------------
SYSTEM
SYSAUD
MGMT_AD4J_TS
USERS
MGMT_ECM_DEPOT_TS
UNDOTBS
SYSAUX

7 rows selected.

Hi Michel - Can you point me to a doc? All I know is that the tablespace is used by the Management Repository. The tables seem to be small in size:

SQL> select * from (
2 select TABLE_NAME,(num_rows * avg_row_len)/1024/1024 SIZEMB from dba_tables where TABLESPACE_NAME='MGMT_TABLESPACE'
3 ORDER BY SIZEMB DESC
4 ) where rownum <= 50;

TABLE_NAME SIZEMB

MGMT_POLICY_ASSOC_CFG 31.7668095
EM_DISC_RAW_RESULTS 28.0714941

MGMT_LONG_TEXT 11.2504444

select owner, sum(bytes)/1024/1024 MB 
from dba_segments where TABLESPACE_NAME='MGMT_TABLESPACE' 
group by owner order by 1;

Thanks, Michel.
It seems the majority of space is taken up by partitions:

OWNER                                  MB 
------------------------------ ---------- 
SYSMAN                          35729.375 
SYSMAN_APM                            .75 
SYSMAN_MDS                         19.875 
SYSMAN_OPSS                         49.25 

SEGMENT_TYPE               MB 
------------------ ---------- 
INDEX                 847.875 
INDEX PARTITION      623.1875 
LOB PARTITION            2992 
LOBINDEX              17.0625 
LOBSEGMENT            289.625 
NESTED TABLE            1.375 
TABLE                 589.125 
TABLE PARTITION         30439


Each partition, on average, is 8MB in size. So, the question is; what's the best way of clearing up this tablespace so i can reclaim some of space?

Regards,
Zabair

It's not exactly poetry in motion, but I hope this is pretty enough for your high standards?:

SQL*Plus format the result for you.
See how is your first post this day now I modified it.

You have to first know which tables own these partitions to know what to purge.

Here's a list of the top storage consumers. What would be the best method of clearing these tables? Truncate?:

SQL> select SEGMENT_NAME, sum(BYTES)/1024/1024 SIZEMB,count(*) TOTAL_PARTITIONS 
  2  FROM DBA_SEGMENTS 
  3  WHERE SEGMENT_TYPE='TABLE PARTITION' 
  4  AND OWNER='SYSMAN' 
  5  GROUP BY SEGMENT_NAME 
  6  ORDER BY SIZEMB DESC;
