Jmeter RTE Plugin Connection timed out: connect

Question

I'm trying to use Jmeter RTE Plugin to make mainframe tests. Using a pconn or wc3270, it`s connects good but trying to record or using an existent JMX file, i'm getting a connection exception.

There is any other configuration that I need to do?

I already tried; reinstall jmeter, java, get a jmeter working installation and script but nothing fixed that issue.

Configs of wc3270 and rte plugin

Answer 1

Coming back on this thread to share the solution and add an information. My jmeter test it`s connecting through VPN connection and the problem it was Java trying to use IPv4 over IPv6 for IPv4 connections. resolution: setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true

Answer 2

Unfortunately we're not able to help without seeing your wc3270 and RTE Config (or RTE Recorder) configuration details.

The exception means that JMeter cannot connect to the host 192.168.2.2 on the given port so I would recommend double checking that you can reach that host using telnet or equivalent.

You can also enable debug logging and see whether jmeter.log file contains any clues.

And finally you can check out Testing Mainframe Environments Using Open Source Tools and cross check it with your setup, maybe you're missing something obvious.
