i found triger, maybe this is problem?
CREATE OR REPLACE TRIGGER CLIENT_AIU
AFTER INSERT
OR UPDATE
ON CLIENT
FOR EACH ROW
DECLARE
vl_operation varchar2(6);
BEGIN
IF INSERTING THEN
vl_operation := 'INSERT';
ELSIF UPDATING THEN
vl_operation := 'UPDATE';
END IF;
mis.newbclient('C:\WINDOWS
:new.id_cli, :new.id_cas_ori,
:new.nom, :new.prenom,
:new.cod_typcli, :new.id_titre,
:new.nom_jf, :new.pseudonyme,
:new.boo_interd,
:new.dat_nai,
:new.boo_fideli);
END;
Check mis.newbclient. It's seems that it is procedure in schema mis.
If it linked to another external database than there where can be performance problems.
As solution, you can create additional table, and put in it new values 'C:\WINDOWS\system32\',vl_
:new.id_cli, :new.id_cas_ori,
:new.nom, :new.prenom,
:new.cod_typcli, :new.id_titre,
:new.nom_jf, :new.pseudonyme,
:new.boo_interd,
:new.dat_nai,
:new.boo_fideli
Remove mis.newbclient(..) from trigger, then create job, which periodically executes mis.newbclient(..) with data from this intermediate table and delete, or mark data in this table after execution.

Make field "visits" not nullable with default value 0.
Gather database statistics.
