the problem is the underlying sys.aud$ table has CLOB columns
yes sdstuber, i am seeing clob objects in aud$, but i am not clob objects in dba_audit_trail, can u help me how to do this..
dba_audit_trail selects from aud$,  so you are pulling the CLOB

but,  dba_audit_trail cuts the CLOB's off at 2000 characters.

you want Oracle to resolve the substr calls before trying to send the data across the link, so you'll have varchar2  results instead of clob results

sometimes you can do that simply by sticking in rownum, because rownum doesn't exist until the results are generated.

this will mean adding an extra column to your testing table though

insert into bginfo.testing@cdb1(select 'db1',rownum, a.* from dba_audit_trail a where timestamp < sysdate or timestamp is null);
you could also try ordering the data, for the same reason.
ordering doesn't happen until the results are done
this way might be slower but it won't require modifying your table structure


insert into bginfo.testing@cdb1(select 'db1', a.* from dba_audit_trail a where timestamp < sysdate or timestamp is null order by timestamp);

oh sorry, the order by isn't allowed on the insert,  did you try the rownum method?
no..what will rownum does..? can u explain me once..
SYS@db1> insert into info.testing@cdb1(select 'UTOLHO01',rownum,a.* from dba_audit_trail a where timestamp < sysdate or timestamp is null);
insert into bginfo.testing@uapxho1(select 'UTOLHO01',rownum,a.* from dba_audit_trail a where timestamp < sysdate or timestamp is null)
                   *
ERROR at line 1:
ORA-00913: too many values
did you add the extra column ?
no dude..
that would do it.


if you include rownum in the select output, you must have a corresponding numeric column in the same position of the table.

or, specify the column order (better option, more robust)  in both the insert and the select

you've changed the query by adding additional table
ajaybelde,

are you sure you got your answer?

http:#36473589 answers the question as to why the error occured but it wasn't selected.

Of the other 3 that were selected, none of the suggestions to address the clob issue were followed.

You did switch to named columns vs '*', but that was a peripheral issue, it had nothing to do with the clob problem you asked about.
