SYSAUX usage is growing

I check that the condition SYSAUX growing cause this condition:

- SM/ADVISOR

- SM/OPTSTAT

- SM/AWR

This occupant size always growing.

I try to running this script to reduce ADVISOR and it works.

BEGIN  
  DBMS_SQLTUNE.SET_TUNING_TASK_PARAMETER (  
  task_name => 'AUTO_STATS_ADVISOR_TASK'  
  , parameter => 'EXECUTION_DAYS_TO_EXPIRE'  
  , value => 31  
  );  
  END;  
  /

The status of SM/ADVISOR is stable "not growing".

But I have different condition for another occupant:

1. SM/AWR -> still growing

2. SM/OPTSTAT -> still growing

With this condition, our SYSAUX tablespace still growing. Could you give us the advice to do reduce this occupant?
