Hi, Have have install Oracle 10g on RHEL4 64 bits on 2 serveurs 1 PE2850 and 1 PE2900 ? We have more performance with the PE2850 than the PE2900 §§§§ As PE2850 processors are quicker than the PE2900 processors but are not Dual Caore and not really 64 bits !!! Do anybody have this problem ? Remy NOLLET
