Hi Guys
hearbeat package also provides an OCF resource for
Oracle(/usr/lib/ocf/resource.d/heartbeat/oracle).
I want to create a cluster of oracle.
# cat /etc/hosts
dbnode1 192.168.0.236 ## hostname and physical IP of server1
dbnode2 192.168.0.238 ## hostname and physical IP of server2
dbserver
:
you must change your listener address in the /etc/hosts and in listener.ora
for use with HA so that it listen also on the common HA-IP-address , e.g.:
( address = ( protocol = tcp ) ( host = HA-VIP ) ( port = 1526)
