I have the scenario:

1 Zabbix Server with 1600 Hosts around 270k items and 300k  triggers, i tryed using the infrastructure with database Oracle RAC but for some reason the the templates on the zabbix-frontend doubled because that i made the rollback with a backup and this time using the oracle with a single node.
I wanna a recommendation to use the Oracle RAC with both nodes or case you have one manual with best-praticts to installing zabbix with Oracle RAC AMS.
