we currently testing Zabbix with an oracle database backend. Here we have an oracle 11g cluster (rac-1.domain.tld) with an oracle 11g standby cluster (rac-2.domain.tld.
So we use in other application (servers) a failoverstring like this:

(description_list=(load_balance=off)(failover=on)( description=(connect_timeout=3)(retry_count=2)(add ress_list=(load_balance=on)(address=(protocol=tcp) (host=rac-1.domain.tld)(port=1540)))(connect_data=(service_n ame= zbxserv)))(description=(connect_timeout=3)(retry_c ount=2)(address_list=(load_balance=on)(address=(pr otocol=tcp)(host=rac-2.domain.tld)(port=1540)))(connect_data=(service_n ame= zbxserv))))

How i can connect this way to an oracle system. An automatic connect after a database failover will be great.
