I was seeing this: -
AMQ7077: You are not authorized to perform the requested operation.
on Windows, whilst trying to stop a Queue Manager: -
endmqm IB9QMGR
having opened a command window ( CMD.EXE ) on a Windows 7 desktop, on which I've got MQ Client and Server v8 installed, along with IBM Integration Bus 9.
Guess what I was doing wrong ?
Yep, I wasn't starting the command window as Administrator.
I had to click [Start] [Run], enter cmd.exe and then right-click and choose Run as administrator.
Once done, I was able to happily stop my Queue Manager.
Then I found this IBM Technote: -
which said much the same thing.
