Oracle uses the OS to handle the routing. If your company is into DNS names then you should not have a problem. Just always specify "host=<hostname>" not "host=192.18.5.5".

We are adding a second nic card for redundancy purposes whereby if one NIC is down, the other NIC would pick up the load. Environment: Sun Solaris Oracle EE 8.1.7.2 The current game plan is documented below: ------------------------- Configure the interface on the sun server * ping from local machine to the new address * ping from other machine on the same subnet to new address Add a second ADDRESS= line to ADDRESS_LIST section in listener.ora file * manually tnsping on db server using: tnsping "(ADDRESS=(PROTOCOL=TCP)(HOST=new.ip.address)(PORT=1521))" * manually tnsping from other machine using same command Add second address to address tnsnames.ora service name (under ADDRESS_LIST section) * tnsping the service name to ensure that some form of it works (this will not check the new interface, necessarily) * use sqlplus to connect to service Add second address to clients' tnsnames.ora files * tnsping service name on each client * use sqlplus to connect to service on each client Physically remove ethernet cable from old NIC on DB server (could be simulated by simply bringing down the network interface in software, but this could cause other problems) * tnsping service name from db server * tnsping service name from clients * use sqlplus to connect to service on db server * use sqlplus to connect to service on each client Replace network cable and/or re-enable interface on db server * tnsping service name from db server * tnsping service name from clients * use sqlplus to connect to service on db server * use sqlplus to connect to service on each client Thanks in advance.
