Starting with 12.1 the setEndToEndMetrics is deprecated, you may use setClientInfo see the documentation for 12.2 here

Here a snippet of the usage

// "conn" is an instance of java.sql.Connection:
conn.setClientInfo("OCSID.CLIENTID", "clientID");
conn.setClientInfo("OCSID.MODULE", "myModule");
conn.setClientInfo("OCSID.ACTION", "myAction");

You may see the setting in V$SESSION with this query of the relevant session

 select MODULE, ACTION, CLIENT_IDENTIFIER from v$session where ...

but only after a next statement is executed with this connection. The call of setClientInfo triggers no extra roundtrip this information is passed whit the next call.

Note also that you must use the Oracle (unwrapped) conenction - Check this for reference.
