Hi I'm kinda new here in message broker I have these problem when I have to test my messageflow, whenever I test the flow, One of its commons with the System.Admin.Command.Queue name
It says.
Cannot access "System Admin command queue" . This usually occurs when queue does not exist. Create the queue and retry the operation.
thanks for the help.

Why exactly do you have a flow using a SYSTEM object?
What possible value do you see in a flow that either adds or intercepts command messages? Unless you're compounding your folly with a flow that adminsiters the queue manager, which isn't a task to be attempted lightly or by someone "kinda new here in message broker"

sorry wrong post! My bad. My messageFlow has this certain commons and whenever I run my message flow the common connected to it with the System.admin.command.queue name provides an Error like the post above!
Shall we say I've taken this kind of training on WMB but I never encountered it on the training. Ive done some research on net and it always takes me on the requesting admin or granting access something. |

What "certain commons"? No flow except the kind of specialised one I alude to above should access the command queue, and I can think of no use case where common code (i.e. code included in multiple flows) would need to do this. Describe exactly what this code is doing and why it's accessing this queue.

So you're kind of new and you've taken some kind of training. Was it training or wasn't it?
Your research is correct. That object is the command queue for the queue manager through which it's administered; because of this access is typically restricted to those people who administer the queue manager to prevent unauthorised changes.
Applications using the queue and other objects on the queue manager (and a broker flow is a particular kind of that application) do not need to access this queue for any reason. Hence my question about what this code is doing.

What is the type of message being sent? Maybe a pcf message? And if yes why is the broker sending a pcf message???

fjb, you seem to have forgotten that this comes up from time to time. People want to do things like 'get queue depth' from a message flow.
It is true that we try to discourage this but does not stop at least one so called Broker Consultant from spending lots of customers money trying to implement something using PCF calls.
We really don't know what these 'commons' do. It might be something like that.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

I've not, and if it is that then my comments to the OP will be:
- your research is correct; you need more authority for the user id that runs your flow
- whoever controls your design standards and whoever wrote this common code (which may be the same or two different people) need to hang their heads in shame

Well in fact I was more thinking along the lines of a get inhibit on the input queue of the flow because a message was out of sequence ... with a roll back to send the current message back to the queue...
Agreed all stuff that should be covered by a different design...
