System could not dynamically load the shared library #390

Closed Seeker911 closed 4 years ago

Seeker911 commented 4 years ago

I have setup the MQ container on my windows 10 machine using Linux containers. I can access the web interface using this uri "https://localhost:9443/ibmmq/console/" and everything seems to work. However I cannot connect to the MQ instance I get an error saying host could not be reached. I can telnet to the port. Looking at the logs however I get this error message.

2020-03-25T20:29:02.613Z AMQ6255E: The system could not dynamically load the shared library '/opt/mqm/lib64/libedit.so'. 2020-03-25T20:29:02.614Z AMQ6175E: The system could not dynamically load the shared library '/opt/mqm/lib64/libedit.so'. The system returned error message 'libncurses.so.5: cannot open shared object file: No such file or directory'.

if i run "ldd libedit.so" using bash I get: libncurses.so.5 => not found libtinfo.so.5 => not found

The libedit error is a known bug in MQ, and is nothing to worry about.

How are you trying to connect? What configuration are you using for MQ? It's worth noting that MQ is not typically configured out of the box — it will be listening on TCP, but won't allow any connections — you need to configure it yourself. The exception is our MQ Advanced for Developers image, which is pre-configured.

Hi Arthur

I have a .net client app that currently connects to our production IBM MQ's I used that initially but could not connect. I did change the config.

I then tried this image and got the same issue : docker run --rm --name mydemoibmmqclient --network mq-dev-network -ti mq-demo

the output is shown below:

Assuming you're using the pre-configured developer image for the server, then the issue I can see in the above example is that the client's connecting to localhost. You'd need to make sure you specify the IP address or host name of the queue manager, on the mq-dev-network network.

Yes. You are correct. By specifying the actual IP of my machine it works fine.

Much appreciated for your time and help.
