LOG ERRORS in Oracle 10G R2

Question

Hi all,
I am learning this new feature. I am having two tables
CREATE TABLE source_tab (col1 number, col2 varchar2(5))
CREATE TABLE taget_tab(col1 number, col2 varchar2(4))
taget_tab.col2 length is one character less compared with source_tab.col2
INSERT INTO source_tab VALUES (1,'AAA');
INSERT INTO source_tab VALUES (2,'BBB');
INSERT INTO source_tab VALUES (3,'CCCCC');
INSERT INTO source_tab VALUES (4,'ddd');
Now, I want to insert data from source table to target table. As data shows, source_tab.col1 with col1=3 will throw error, as its col2
size is more than the target table, but i want to continue with the execution and log the this value(3) in log table(logtmp) by using LOG ERRORS
feature of 10Gr2.
I have created log table like this manually
create table logtmp
ORA_ERR_NUMBER$ NUMBER ,
ORA_ERR_MESG$ VARCHAR2(2000),
ORA_ERR_ROWID$ ROWID,
ORA_ERR_OPTYP$ VARCHAR2(2),
ORA_ERR_TAG$ VARCHAR2(2000),
col1 number
Is this possible, if so, please give me the idea.
Thanks in advance.
Thanks,
Pal

See the following example.
/* Table creation */
CREATE TABLE source_tab (col1 number, col2 varchar2(5));
CREATE TABLE target_tab(col1 number, col2 varchar2(4));
execute DBMS_ERRLOG.create_error_log (dml_table_name => 'TARGET_TAB', err_log_table_name => 'LOGTMP');
desc logtmp;
INSERT INTO source_tab VALUES (1,'AAA');
INSERT INTO source_tab VALUES (2,'BBB');
INSERT INTO source_tab VALUES (3,'CCCCC');
INSERT INTO source_tab VALUES (4,'ddd');
commit;
/* Insert that runs into errors */
insert into target_tab
select * from source_tab
log errors into LOGTMP reject limit unlimited;
select * from logtmp;
/* cleanup */
drop table source_tab;
drop table target_tab;
drop table logtmp;Consider to run this step by step.
And here is the relevant output from it.
desc logtmp

COL2                 VARCHAR2(4000)
ORA_ERR_NUMBER$ ORA_ERR_MESG$ COL1 COL2
