Disable Auto Space Advisor

On our production database Segment Space Advisor jobs were running very frequently with different names “SYS.ORA$AT_SA_SPC_SY_***”.  That was causing 100% of IO activity when was creating advise on the table containing XML files . LOB segment space for this table is 565G.

In my opinion, it is fare to disable this auto task and run manually whenever you want.

BEGIN
DBMS_AUTO_TASK_ADMIN.disable(
client_name => ‘auto space advisor’,
operation => NULL,
window_name => NULL);
END;
/

Check the status:

SQL> select client_name, status
2 from dba_autotask_client;

CLIENT_NAME STATUS
———————————————-
auto optimizer stats collection ENABLED
auto space advisor DISABLED
sql tuning advisor DISABLED

Thanks to Fikria for this case 🙂
