Hi everyone,
is this possible. Anyone examples for me?
How do I tell the PCFAgent that he should connect to QM_2 but get information from QM_1?

Use QM_2 to redirect the PCF message to QM_1. Standard request/reply/remote queue stuff.

So you want to tell me that this is not possibla with the Admin API and I have to use MQ API instead? That is just great ...

I want to tell you nothing of the kind! 
Unless there's something weird about the PCFAgent I'm unaware of that locks it to a specific location. Possible, given my level of Java knowledge.
But in concept it should be straightforward enough.

 I think I understand the concept but I have no idea how to tell the PCFAgent to forward my request to QM_1. I am creating new PCF Agent via
| Code: |
new PCFAgent(host, port, channel);
|
so it connects directly to the queue manager runing under host X and with port Y. Now I found nothing about a method or constant which allows me to forward my request. However MO71 has the option to do this. So I think it is possible. But ... how?!

Ah - so it is some weird Java thing I'm unaware of!
Clearly the PCFAgent is directly attaching to the queue manager in question rather than simply generating a PCF message. So you're right, it's not possible with PCFAgent.
Time to RYO PCF messages methinks.....

| You don't tell the Agent to connect to the remote queue manager. You construct PCFMessages that are destined for the remote queue manager. |

Now I thought that, until all these connection details started getting bandied about.....

Jeff I am constructing a PCFMessage as follows.
| Code: |
PCFMessage request = new PCFMessage (CMQCFC.MQCMD_INQUIRE_Q);
request.addParameter (CMQC.MQCA_Q_NAME, "*");
|
How do I construct this message for a remote queue manager? Can you provide code examples?
I was trying the following
| Code: |
request.addParameter(CMQC.MQCA_Q_MGR_NAME, qMgr);
|
but then I am getting MQRC 3016 which is MQRCCF_MSG_LENGTH_ERROR.

| I'd suggest you use a different constructor from the PCFMessage class. |

Search for one that allows you to set the destination qmgr and queue on the MQMD. Have fun

I was trying it as follows.
| Code: |
MQEnvironment.hostname = "XXX";
MQEnvironment.port = 1414;
MQEnvironment.channel = "XXX";
MQEnvironment.userID = "xxx";
try {
// connecting
MQQueueManager qmgr = new MQQueueManager("XXX");
// connected
// open pcf request and reply queue
String replyQueueName = "PCF.REPLY";
MQQueue adminQueue = qmgr.accessQueue(
qmgr.getCommandInputQueueName(),
MQC.MQOO_INPUT_EXCLUSIVE, "", "", "mqm");
MQQueue replyQueue = qmgr.accessQueue (
"SYSTEM.DEFAULT.MODEL.QUEUE",
MQC.MQOO_INPUT_EXCLUSIVE, "", replyQueueName, "mqm");
// generate request
MQMessage message = new MQMessage();
message.messageType = MQC.MQMT_REQUEST;
message.expiry = 100;
message.feedback = MQC.MQFB_NONE;
message.format = MQC.MQFMT_ADMIN;
message.replyToQueueManagerName = "XXX";
message.replyToQueueName = replyQueueName;
PCFMessage request = new PCFMessage(CMQCFC.MQCMD_INQUIRE_Q);
request.addParameter (CMQC.MQCA_Q_NAME, "*");
request.addParameter (CMQC.MQIA_Q_TYPE, CMQC.MQQT_LOCAL);
request.addParameter (CMQCFC.MQIACF_Q_ATTRS,
new int [] { CMQC.MQCA_Q_NAME, CMQC.MQIA_CURRENT_Q_DEPTH });
request.write(message);
MQPutMessageOptions pmo = new MQPutMessageOptions ();
// sending request
adminQueue.put(message, pmo);
// send
} catch (MQException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
|
But there is simply no option where I can set the destination queue manager YYY  MQMessage does not provide s.th. like destination queue manager. Nobody was trying this?

Sorry,I was not thinking it through clearly.
You need to use a different connect method. |

Thanks for this hint Jeff. Using this method
| Code: |
connect(com.ibm.mq.MQQueueManager qmanager, java.lang.String targetQueue, java.lang.String targetQmanager)
|
helped
