I am using WMQ 701 on Windows

I previously placed the same user name and pw on my clients to get authorization. I can no longer do that

I placed my client user name into the MCA of the svrconn channel of my server qmgr. That allowed me access from the MQExplorer

However, I can not access from my java client. I get the following error:

Code:

I put the user ID into the MCA of the channel, is that all I need to accomplish or is there something else

Do I need to define the pw ?

Thanks

Did you create the MCAUSER you supplied in the system the queue manager is running? The user you supplied at MCAUSER should exist in the system in order a client to be able to make a conneciton and the user should have limited ( desired) permission.

As far as I know, MQ does not authenticate and so it does not use password.

hope helps

Thanks, I read that , but forgot about it once I started testing.

Does that rule (creating the user on the server as well as the client) also apply to the z/OS system as well ?

It applies on every system. How else will the system be able to check the user? (LDAP etc. notwithstanding).

I just got this configuration to work with the MCAUSER:

Code:

Server Machine:

User: broker1
Member of: Administrators
mqbrkrs
mqm
Note: (This is the ID under which MQ and WMB were installed)

User: test01
Member of: Administrators
mqbrkrs
mqm

SVRCONNN Channel has MCA of test01

Client Machine:

User: test01
Member of: Administrators
Remote Desktop Users
Users
Note: (No MQ installation is on this machine, only client DLL's)

But it did not work until I made test01 a member of "Administrators" on BOTH the server and client machines.

Why would this work only with Administratotr access ?

Because Administrator usually has mqm authority & this bypasses security.

Did you do a dspmqaut to determine that the MCAUser has the correct authorizations on the target queue manager? Including connect, which many people overlook?

You could also remove the MCAUser from the Administrator group then enable security events to see what it's failing against.

Could it be that you need administrator access on the client machine to go TCP over the MQ port/protocol to the server? Firewall access etc...?
And by the way install the full MQ client on the client machine. It is much cleaner when doing upgrades...
