Zabbix 3.0 with Oracle 11 database with DRCP

[knightrider]

Currently, we have Zabbix 3.0 running with the Oracle 11 database. We are moving the database to a new server. Our DBA has recommended we use DRCP in Oracle. Has anyone implemented Oracle DRCP with Zabbix?.
What are the configuration changes required to successfully implement DRCP in Zabbix?

Usually using DRCP does not make to much sense with zabbix.
Why?
Because almost each zabbix server/proxy process opens single connection to DB backend and each of those processes keeps opened such connection as long each of these processes is running. On top of those fixed set of processes is added another pool of connections from web frontend and here as well each http session opens single DB backend session.
Usually even pool of web connections is quite constant.
