Recently, I have upgraded my laptop to windows 7. also, I installed mq7.1. While verifying installation, I tried to run amqsputc with setting mqserver variable which I have done hundreds of times. But this is failing this time. I tried to read and figure out but am unable.

I used to get 2538/39 and eventually 2035.

The other things, IBM doc suggest to set dcomcnfg and I did not find ibm mqseries under DCONG node.

I tried setting mcauser
tried with giving channel authority

nothing works.
I am getting the following error

C:\Windows\system32>set MQSERVER=SYSTEM.DEF.SVRCONN/TCP/localhost(2414)

C:\Windows\system32>amqsputc Q1 MB7QMGR
Sample AMQSPUT0 start
MQCONN ended with reason code 2035

C:\Windows\system32>amqsputc Q1 MB7QMGR




Have any one of you have encountered similar issue with mq7.1/windows 7 ?

Thanks

channel security is different in 7.1
Think of an inbuilt ipsec2 exit that will refuse the usual all powerfull group unless told specifically to accept it...

read up on the channel authorization records and I don't mean setmqaut...

Have fun

I have some suspicion but was not sure. this does the magic
alter qmgr chlauth(disabled)'

Yes, this is a workaround.

No, do not use it. It's terrible. It unlocks your entire queue manager.

Even in Dev, it's much better to just create a new chlauth record for a specific channel that allows access to mqm. It's even better to just delete the predefined rule, than to disable chlauth entirely.

DO NOT DISABLE CHLAUTH.

Yes that is next thing I have to do.

I have another issue.

After upgrading my laptop ( not the production systems) to mq7.1, when I tried to use rfhutil/MQ71 to connect to remote systems, it is giving me 2059. But I can add the queue manager successfully in explorer. Not sure what is going on ? will this chlauth cause in this case? the channel I am using for remote system is of the existing system, but the client is the 7.1. would the client also cause the issue?

MQExplorer (java) and RFHUtilc just like MO71 have a different authentication mechanism / model.
I'd say working as designed... and yes it is most likely due to the user you are trying to connect with...

I understand that, but as I am connecting to b7.01.*, how the chlauth feature of of mq71. would affect the connection? also error code is not 2035 but 2059 .

in order to get a 2035 the user name has to be flowed through and the attempt to start the channel needs to be made. If on the other side the program shuts down the channel before even flowing the user through because it is not one of the allowed user, you may well get a 2059...

How can we create a new chlauth to allow access to an administrator user in Windows?? Will the below work??

SET CHLAUTH('*.SVRCONN') USERSRC(MAP) MCAUSER(<userid>)[/quote]

That does not work. The admin users are blocked by blockuser rule, so you have to create another blockuser rule as follows for your particular channel:

set chlauth(yourserverconn) TYPE(BLOCKUSER) USERLIST('nobody') ACTION(ADD)

Google 'linux-nobody' - learn to use Google, it can be your friend.
