• Reducing the Space Usage of the SQL Management Base in the SYSAUX Tablespace (Doc ID 1499542.1)
• How to Reduce SYSAUX Tablespace Occupancy Due to Fragmented TABLEs and INDEXes (Doc ID 1563921.1)

1、 First of all to see SYSAUX Usage of tablespace objects ：

  

   set lines 130set pages 10000col SgmntSize heading 'Sgmnt|Size|Mb'col SgmntSize format 99999col TSname heading 'TSpace|Name|'col TSname format a25col SgmntOwner heading 'Sgmnt|Owner|'col SgmntOwner format a15col SgmntName heading 'Sgmnt|Name|'col SgmntName format a35col SgmntType heading 'Sgmnt|Type|'col SgmntType format a5SELECT ROUND(SUM(ds.bytes)/1024/1024,0) as "SgmntSize", ds.TableSpace_name as "TSname", ds.owner as "SgmntOwner", ds.segment_name as "SgmntName", ds.segment_type as "SgmntType"FROM dba_segments dsWHERE ds.segment_type IN ('TABLE','INDEX')AND TableSpace_name = 'SYSAUX'GROUP BY ds.TableSpace_name, ds.owner, ds.segment_name, ds.segment_typeORDER BY "SgmntSize" DESC;
  

2、 adopt DBMS_SPM.DROP_SQL_PLAN_BASELINE Delete unwanted SQL The baseline .

3、shrink space
It is recommended to do this when the database load is light ：

  

   select space_usage_kbytes from v$sysaux_occupants where occupant_name = 'SQL_MANAGEMENT_BASE';alter table "SYS"."SQL$" enable row movement;alter table "SYS"."SQL$TEXT" enable row movement;alter table "SYS"."SQLOBJ$AUXDATA" enable row movement;alter table "SYS"."SQL$" shrink space cascade;alter table "SYS"."SQL$TEXT" shrink space cascade;alter table "SYS"."SQLOBJ$AUXDATA" shrink space cascade;alter table "SYS"."SQL$" disable row movement;alter table "SYS"."SQL$TEXT" disable row movement;alter table "SYS"."SQLOBJ$AUXDATA" disable row movement;alter table "SYS"."SQLOBJ$" shrink space cascade;alter table "SYS"."SQLOBJ$DATA" shrink space cascade;alter table "SYS"."SQL$" modify lob ("SPARE2") (shrink space cascade);alter table "SYS"."SQL$TEXT" modify lob ("SPARE2") (shrink space cascade);alter table "SYS"."SQL$TEXT" modify lob ("SQL_TEXT") (shrink space cascade);alter table "SYS"."SQLOBJ$" modify lob ("SPARE2") (shrink space cascade);alter table "SYS"."SQLOBJ$DATA" modify lob ("COMP_DATA") (shrink space cascade);alter table "SYS"."SQLOBJ$DATA" modify lob ("SPARE2") (shrink space cascade);alter table "SYS"."SQLOBJ$AUXDATA" modify lob ("SPARE2") (shrink space cascade);
