I installed MQ v.8 on AIX.v.7, then,
I created and started a queue manager called QM1
On QM1 I Defined a local queue called QUEUE1
I then installed MQexplorer v.9.1 on my Linux laptop. In MQE I tried to add the remote QM1 I created. But I get this MQE error: "Could not establish a connection to the queue manager - reason 2538. (AMQ4059)"
How do I configure my QM1 to allow a connection from MQE. What if I want to allow a READ only access or FULL-CONTROL access? |

Google is you friend.
What research have you done?
What does r/c 2538 tell you?
What does AMQ4059 tell you?
What actions do these tell you?

Hi Bruce
Thank you for your help Bruce, I did try to google How+to+configure+IBM+MQ+to+allow+MQ+explorer+connections but every thing seems to point to that MQE is already conected to MQ. So I am sort of stuck.
What does r/c 2538 tell you? An MQCONN call was issued from a client to connect to a queue manager but the attempt to allocate a conversation to the remote system failed. Common causes of this reason code are:
The listener has not been started on the remote system.
The connection name in the client channel definition is incorrect.
The network is currently unavailable.
A firewall blocking the port, or protocol-specific traffic.
The security call initializing the IBM® WebSphere® MQ client is blocked by a security exit on the SVRCONN channel at the server.
What does AMQ4059 tell you? AMQ4059 = Could not establish a connection to the queue manager.
What actions do these tell you? That I need to somehow configure MQ to allow MQE to connect ? |

Somehow?
Did you search for 'how to connect MQExplorer to server' or something similar?
I searched with this exact wording (above) and found this as the first search result:https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_9.0.0/com.ibm.mq.ins.doc/q009345_.htm
Setting up the server and client using IBM MQ Explorer on Windows

THIS should give you a starting point but I also advise you to search out Morag Hughson's articles on CHLAUTH etc., especially if you intend to map any users to a privileged user.

Hi Bruce I did find that article, but as I said it and many others assume that MQE is already able to connect to MQ. |

Q1) do you have a listener on the remote system?
Q2) Is the connection name correct, using the port that the listener is listening on?
Q3) Is the network available? Can you ping the machine the queue manager is on?
Etc
Once you fix the network connectivity problems, you will then come across a different return code, and then you're into allowing access from a security perspective and my posts on configuring CHLAUTH etc may be helpful to you.
Cheers,

P.S. Perhaps you'd like some MQ training? Our "First Steps with MQ" module is free, see link in my sig

Hi Morag, I will definitely take your "First Steps with MQ" module, thanks for sharing. As far as you question: Q1) do you have a listener on the remote system?
Well no I have not, I don't know how to do that. Can you provide an example? The only thing I have done so far are the steps I spelled out above. But I can't seem to find any info on how to set this up even tho it seems like it should be very simple |

Sorry. Not simple, but part of system admin basic training courses.
Get training. IBM offers MQ V9 System Administration training with lecture and hands-on lab exercises.
Also, search for MQ primer documentation. Download and read.

Hi Bruce, Thanks....I have down loaded the primer...no luck there.
You said it wont be simple to config MQ to allow MQE to connect to it, I guess you are correct because I can't find it anywhere and no one here seems to have the exact commands. Odd I would think this simple task would just take just two or so simple commands, but I guess that's not the case at this for me being a newb  |

It contains information not luck; it's a book not a 4 leaf clover.

No, we don't.

Guess again.

No, it's not the case because it's not just 2 or so simple commands. I've been working with MQ for a little over 2 decades and it's not 2 or so simple commands for me either.
Morag has offered you her free training and I cannot endorse her work (all of it) highly enough. Once you move past this and into production strength MQ, you'll find her insights into security invaluable.
Even in this thread, her decomposition of the error message is right on the money:

Q1) do you have a listener on the remote system?
Q2) Is the connection name correct, using the port that the listener is listening on?
Q3) Is the network available? Can you ping the machine the queue manager is on? |
So locate in the primer and the documentation how and where to define a listener, if you don't have one. That's 2 or so commands and are specific to your configuration - see below
Once you've defined that and got it running, establish a connection channel using the information in the primer and the link @Exerk provided. Again, this will be specific to your set up and 2 or so commands.
Then you fight it out with the network and this will be the most specific part of all as the connection channel, listener and other components must be set to values allowed by your network and where (for example) MQ traffic is allowed to flow to the port specified.
I wish you good fortune as you move from newb to expert.

Please consider...
Many come here as newbs. We enjoy helping, but we appreciate those who first help themselves.
Reading, training, basic research, trial and error, are the primary tools for acquiring and ultimately mastering a skill.
Asking us to look up error messages and ReasonCodes, or how to issue commands is NOT helping yourself.
We are volunteers here. Most/many of us are paid to do MQ work, either as an employee or as a consultant. I'm confident that you could engage one of us to come to your site in one capacity or the other to do the needful.

After installation, did you verify your installation? The instructions should have taken you to this page:-
Setting up the server using the command line on AIX
These are probably the instructions you are looking for.
