Error when analysing schema

Question

Hi,
I want to analyse our main schema every week so that Oracle Discoverer can give us better query predictions. Every sunday, I run this :
EXEC dbms_stats.gather_schema_stats(ownname => 'ACAIQ',options => 'GATHER AUTO', cascade => TRUE);
But after a couple of seconds, I get :
ERROR at line 1:
ORA-01652: unable to extend temp segment by 64 in tablespace TEMP
ORA-06512: at "SYS.DBMS_STATS", line 9339
ORA-06512: at "SYS.DBMS_STATS", line 9810
ORA-06512: at "SYS.DBMS_STATS", line 9982
ORA-06512: at "SYS.DBMS_STATS", line 10059
ORA-06512: at "SYS.DBMS_STATS", line 10036
ORA-06512: at line 1
TEMP is a TEMPORARY tablespace, so I don't understand why I get this error :-/

Answer 1

DBMS_STATS uses temporary segments and it cannot extend temporary tablespace. Resize your tempfile or add another one to the tablespace. For example :
SQL> select file_name, bytes from dba_temp_files;
FILE_NAME                                     BYTES
/u01/app/oracle/oradata/orcl/temp02.dbf    52428800
SQL> alter database tempfile '/u01/app/oracle/oradata/orcl/temp02.dbf' resize 100M;
Database altered.
SQL> select file_name, bytes from dba_temp_files;
FILE_NAME                                     BYTES
/u01/app/oracle/oradata/orcl/temp02.dbf   104857600
