How to reduce sysaux tablespace size with Audit Trail Unified enabled I have Oracle 12c Standard instance with dev database with enabled Audit Trail Unified.

And now SYSAUX tablespace has size 32Gb, but all data is only 9Gb.
When I tried to reduce size of SYSAUX I received an error message:

ORA-03297: file contains used data beyond requested RESIZE value

Then I saw that some big sized objects in this tablespace:


I've executed the following scripts:

BEGIN
DBMS_AUDIT_MGMT.SET_LAST_ARCHIVE_TIMESTAMP(
   audit_trail_type =&gt; DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED,
   last_archive_time =&gt; SYSDATE-1,
   rac_instance_number =&gt; 1 /* single instance database */),
   container            =&gt; DBMS_AUDIT_MGMT.container_current;
END;
/      


BEGIN
DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
audit_trail_type =&gt; DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED,
use_last_arch_timestamp =&gt; TRUE);
END;   
/


After this in AUDSYS."CLI_SWPXXXXXXX" table I don't see any rows.
But it still have the same size .

Also any attempts to shrink this table or move it to another tablespace give me an error message: 
ORA-55941: DML and DDL operations are not allowed on table "AUDSYS"."CLI_SWPXXXXXXX"

So, my question is: can I make size of SYSAUX tablespace smaller or move this audit tables to another tablespace?

Update: by this link: click I've found info that "Moving CLI.SWP possible only for Enterprise edition, for standard impossible due partitioning." Is that true? It seems like my instance is Standard...
SQL&gt; select owner||'."'||table_name||'"' t from dba_tables where table_name like 'CLI_SWP$%';
