Good morning,
Running Oracle RAC and having a problem with supporting the way Oracle
does VIP address fail over.
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...
Thank you,
Paul...
