But there is a Workaround for this, you can disable the “auto space advisor” feature which is the cause for triggering shrink space for large tables.

Steps to disable the “auto space advisor”

1. Check the status of the “auto space advisor”.

SQL> SELECT client_name, status FROM dba_autotask_client;
set lines 180 pages 1000
col client_name for a40
col attributes for a60
select client_name, status,attributes,service_name from dba_autotask_client;

2. Execute the below to disable the “auto space advisor”.

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

3. Check if the “auto space advisor” is disabled.

set lines 180 pages 1000
col client_name for a40
col attributes for a60
select client_name, status,attributes,service_name from dba_autotask_client;

Restart the Extract process after disabling the “auto space advisor”.

Note: Please check with your Oracle Core DBA before disabling this “auto space advisor”..
