Hi,
I have tried connecting to queue manager using MQConfigManagerConnectionParameters and MQPropertyFileConfigManagerConnectionParameters. But, in both cases, I get MQRC 2012 which is an environment error. This is for Queue Manager and Broker on z/OS. I admit, I do not quite follow the reasons for the error and so have sent an email to the SysProgs. But, I do not follow, as to why the connection proceeds when the IP address is omitted from the MQConfigManagerConnectionParameters constructor. Although, with this approach, the ConfigManagerProxy.getInstance fails.
I am trying to get ESQL work with UDP...

Is the CMP app running on zOS or somewhere else?
I know that for some purposes, with the CMP API you don't technically need the CAF to use it, but not all, if I recall correctly.
Does the same code work fine when talking to a non-zOS broker (Or configMgr if you're at v6.1) |

Unless this is WMBv7 (which you've not seen fit to mention) you should be connecting to the ConfigMgr not the broker.

Why? How? I don't see how these would intersect unless you mean something else than what I understand by UDP.
And what does the purpose of your ESQL have to do with CMP?

Yeah, it's a little confusing.
Cogito-Ergo-Sum is using the methods that connect to a ConfigMgr, but talking about connecting to the Broker.
Hopefully this is v6.1. |

Well if it is v7, and my understanding is correct, those CMP calls remain for backward compatibility even though there's no Config Mgr in v7.
a) I could be mistaken about that
b) They could do something different in v7
c) You might be able to do some of the calls (like the deploy) but the enquiry calls don't work
All this could also be utterly unrelated to the 2012.

They exist, but do not function. You need to use MQBrokerConnectionParameters and etc. rather than MQConfigMgrConnectionParameters...
And yes, it may have nothing to do with the 2012. |

Ah. That's worth knowing.
I love it when I learn something. Even if what I learn is "I still don't have enough time to really look into WMBv7"

Yes, this is on 6.1.
I am following the sample from here. I have extended the sample as :
| Code: |
ConfigManagerConnectionParameters cmcp = new MQConfigManagerConnectionParameters("hostname", 1414, "QMGR");
ConfigManagerProxy cmp = ConfigManagerProxy.getInstance(cmcp);
TopologyProxy t = cmp.getTopology();
BrokerProxy b = t.getBrokerByName("BRK1");
ExecutionGroupProxy e = b.getExecutionGroupByName("EG01");
MessageFlowProxy m = e.getMessageFlowByName("cmp01.CMP01");
String[] udps = m.getUserDefinedPropertyNames();
|
The CMP app runs on z/OS.

I would change
| Code: |
ConfigManagerConnectionParameters cmcp = new MQConfigManagerConnectionParameters("hostname", 1414, "QMGR"); |
to
| Code: |
ConfigManagerConnectionParameters cmcp = new MQConfigManagerConnectionParameters( "QMGR"); |
or whatever the correct version to indicate a local qmgr is.
And, again, make sure that it is the ConfigMgr that is using QMGR instead of or as well as the Broker. |

The permissible syntax seems to be the following:
| Code: |
ConfigManagerConnectionParameters cmcp = new MQConfigManagerConnectionParameters("",1414,"QMGR");
|
That results in:
| Code: |
com.ibm.broker.config.proxy.ConfigManagerProxyPropertyNotInitializedException: Information on the Topology has not yet been supplied by the Configuration Manager; consequently the broker information could not be determined. |

Well, it's not an MQRC 2012! 
Have you registered a Broker with the ConfigMgr and deployed the topology? |

Well, there is a broker running by name BRK1 connected to QMGR queue manager and a ConfigMgr named as QMGRCMGR. And, BRK1 does have and execution group EG01 with message flow as cmp01.CMP01.
I hope, that is what you asked ...

Odd name. Are you trying to run the CMP from inside the EG?

Mostly, but you still have not clarified where this 2012 is coming out & when.

The CMP runs from a JavaCompute node in a message flow cmp01.CMP01. )Sorry....I should have told this before probably.) The 2012 comes from this JCN when the constructor has all arguments passed.

Why? Why not a standalone Java app?

And you believe the JCN has the correct environment for WMQ set up because.....?
