清理核心SYSAUX表空间

一、检查SYSAUX表空间使用情况；如下：

1.当前空间总大小大约180G左右，日增大约350M左右；

TABLESPACE_NAME SIZE_USED_MB DATA_SIZE_MB FREE_RATE MAX_SIZE_MB

FREE_MB MAX_FREE_RATE AVG_USED_PER_DAY_MB TBS_EXHAUST_DAYS

------------------------------ ------------ ------------ ---------- -----------

---------- ------------- ------------------- ----------------

SYSAUX 186005 217087 14 217087

31082 14 343.3 91

2.检查SYSAUX中个部分大小，发现SM/AWR这一部分占了95%以上的空间；如下：

set lines 9999 pages 999

col Item for a30

col schema for a20

col Move_Procedure for a30

SELECT occupant_name "Item",

space_usage_kbytes / 1048576 "Space Used (GB)",

schema_name "Schema",

move_procedure "Move Procedure"

FROM v$sysaux_occupants

ORDER BY 1;

Item Space Used (GB) Schema Move
