We recently upgraded our LAN network from 1G to 10G but the Oracle OVS servers network cards showed only 1G link even though the advertised link was 10G. [root@ovs1 ~]# ethtool em1 Settings for em1: Supported ports: [ FIBRE ]…
Although we have quite wide Oracle Linux stack I had not come across with pam_tally2 before we got Exadata. If you haven’t read about it it’s module which takes care of failed logins and locks account after certain number of…
