Oracle unexpire password

Interroga

Per vedere se ci sono utenti con password scaduta o in scadenza.

select username from dba_users where account_status in ('EXPIRED','EXPIRED(GRACE)');

Per account bloccati:

select username from dba_users where account_status='LOCKED';

Normalmente gli account di sistema sono in stato 'EXPIRED & LOCKED':

da SQLPLUS bisogna disattivare l'opzione define per consentire valori con &

set define off
select username from dba_users where account_status='EXPIRED & LOCKED';

Imposta per evitare la scadenza

create profile nopasswdexpire_profile limit PASSWORD_LIFE_TIME unlimited FAILED_LOGIN_ATTEMPTS unlimited PASSWORD_VERIFY_FUNCTION null;

set define off

begin
for c1 in (select username from dba_users where profile='DEFAULT' and account_status!='EXPIRED & LOCKED')
loop
  begin
   execute immediate 'alter user ' || c1.username || ' profile nopasswdexpire_profile';
   exception
    when others then
	  null;
  end;
end loop;
end;
/

Per CDB:

create profile c##nopasswdexpire_profile limit PASSWORD_LIFE_TIME unlimited FAILED_LOGIN_ATTEMPTS unlimited PASSWORD_VERIFY_FUNCTION null;

begin
for c1 in (select username from dba_users where profile='DEFAULT' and account_status!='EXPIRED & LOCKED')
loop
  begin
   execute immediate 'alter user ' || c1.username || ' profile c##nopasswdexpire_profile';
   exception
    when others then
	  null;
  end;
end loop;
