I suggest using the same Network for Oracle VIP on both sides. You need to :
System A Home address 192.168.127.1 ETH0 Oracle VIP 192.168.128.1 ETH1 Oracle Priv 192.168.87.1 ETH2 System B Home address 192.168.127.2 ETH0 Oracle VIP 192.168.128.2 ETH1 Oracle Priv 192.168.87.2 ETH2 Jakub Szefler Administrator MainFrame Pion Operacji IT Grupy TP/Departament Infrastruktury Wydział Infrastruktury Informatycznej Dział Mainframe __________________________________________________________________ Treść tej wiadomości zawiera informacje przeznaczone tylko dla adresata.

This environment has two z9 systems running z/VM 5.3 with Vswitch on each and a linux (rhel 44). On each z/VM the Vswitch is setup to support a specific subnet. Vswitch on System A side supports 192.168.127.* Vswitch on System B side supports 192.168.87.* Oracle on linux on system A has Home address 192.168.127.1 ETH0 Oracle VIP 192.168.127.2 ETH0:1 Oracle Priv 192.168.127.3 ETH1 Oracle on linux on system B has Home address 192.168.87.1 ETH0 Oracle VIP 192.168.87.2 ETH0:1 Oracle Priv 192.168.87.3 ETH1 * The problem; If something happens on the system A side and access is lost (at any level) Oracle on the system B side brings up via ETH0:2 the VIP address of the lost system. So now system B linux looks like this; Home address 192.168.87.1 ETH0 Oracle VIP 192.168.87.2 ETH0:1 Oracle VIP 192.168.127.2 ETH0:2 Oracle Priv 192.168.87.3 ETH1 A Q VSWITCH DET shows the 192.168.127.2 address known in the Vswitch, but it can not be routed to. Is there anything that can be done in he Vswitch to help advertise just this address only, since all the other 192.168.127.* addresses are still on the other system...
