HI
1) Step create table:
CREATE TABLE SYS.DDL_LOG
  DBNAME         VARCHAR2(50 BYTE),
  USERNAME       VARCHAR2(30 BYTE),
  OBJECTNAME     VARCHAR2(200 BYTE),
  OBJECTTYPE     VARCHAR2(30 BYTE),
  OPERATIONTYPE  VARCHAR2(50 BYTE),
  DDLDATE        DATE,
  SQLTEXT        CLOB,
  MACHINE        VARCHAR2(50 BYTE),
  APPLYFLAG      VARCHAR2(1 BYTE),
  OBJECTOWNER    VARCHAR2(30 BYTE),
  ACTION         VARCHAR2(40 BYTE),
  CLIENTINFO     VARCHAR2(40 BYTE)
2) Step create TRIGGER SYS.DDL_TRIGGER
CREATE OR REPLACE TRIGGER SYS.DDL_TRIGGER
AFTER DDL
ON DATABASE
declare
sql_text ora_name_list_t;
stmt clob;
n number;
v_terminal varchar2(30);
v_action varchar2(40);
v_applyflag  varchar2(1);
v_client_info varchar2(40);
begin
SELECT action into v_action   FROM v$session where sid= ( select distinct sid from v$mystat ) ;
if v_action = 'NOLOG' then   v_applyflag := 'X'; else  v_applyflag := '0'; end if;
SELECT SYS_CONTEXT('USERENV','TERMINAL') into v_terminal FROM DUAL;
SELECT SYS_CONTEXT('USERENV','ACTION') into v_action FROM DUAL;
v_client_info:=substr(SYS_CONTEXT('USERENV','ENTERPRISE_IDENTITY'),1,40);
if ora_dict_obj_type   in ( 'FUNCTION','PROCEDURE','PACKAGE','PACKAGE BODY','TRIGGER',
                            'JAVA CLASS','JAVA DATA','JAVA RESOURCE','JAVA SOURCE',
       'LIBRARY')
                                   and ora_sysevent in ( 'CREATE','ALTER' )
       then
   stmt := NULL;
else
   n := ora_sql_txt(sql_text);
   if n > 1000 then n:= 1000; end if ;
         FOR i IN 1..n LOOP
          stmt := stmt || sql_text(i);
        END LOOP;
end if;
     insert into ddl_log values
     ora_database_name,
     ora_login_user,
     ora_dict_obj_name,
     ora_dict_obj_type,
     ora_sysevent,
     sysdate,
     stmt,
     v_terminal,
     v_applyflag ,
  ora_dict_obj_owner,
      v_action,
      v_client_info
end;
Thank you
