Hi,
What System Q and Channel should be used when trying to execute PCF Commands using MQ Client connection. Currently I am using the Channel SYSTEM.DEF.SVRCONN and Q SYSTEM.DEFAULT.LOCAL.QUEUE to send a PCF Command.
I see the Command on the Q but its not executed. I send the reply to a local Q on the same Q manager that I connect to for the SYSTEM.DEFAULT.LOCAL.QUEUE.
I am under the assumption that I can send the reply back to any Local Q on any Q mgr on the MQ Series by specifying that in the sent message header. is that true?
Are there any other parameter such as persistence, time wait, message id ... etc that need to be taken care of ?
Thanks

From the manual
| Quote: |
The queue to which the PCF commands are sent is always called the SYSTEM.ADMIN.COMMAND.QUEUE. The command server servicing this queue sends the replies to the queue defined by the ReplyToQ and ReplyToQMgr fields in the message descriptor of the command message.
|
So, you shouldn't be sending them to SYSTEM.DEFAULT.LOCAL.QUEUE but to SYSTEM.ADMIN.COMMAND.QUEUE |

Hi,
This is the code I use to put the Command on the System Admin Queue. It gives me a n error code of 2085. Can Somebody help on this?
Does it require any settings to be done on MQ Series Server side ?
In future i wud like to be connected to any Qmgr on the system.
Thanks
Jigs

int [] attrs = { CMQC.MQCA_Q_NAME, CMQC.MQIA_CURRENT_Q_DEPTH };

String name = null;
String depth = null;
// MQEnvironment.disableTracing();

MQEnvironment.hostname = args [0];
MQEnvironment.port = Integer.parseInt (args [1]);
MQEnvironment.channel = args [2]; //SYSTEM.DEF.SVRCONN

message.replyToQueueManagerName = "MQ02";
message.replyToQueueName = "BRIDGE.TEST.IMS.REPLYTO.QUEUE";
MQCFH.write (message, CMQCFC.MQCMD_INQUIRE_Q, 3); // 3 parameters follow

MQCFIN.write (message, CMQC.MQIA_Q_TYPE, CMQC.MQQT_ALL);
MQCFIL.write (message, CMQCFC.MQIACF_Q_ATTRS, attrs);
System.out.print ("Sending PCF request... ");
sys_def_local_q.put(message, pmo);
System.out.println ("Sent.");
sys_def_local_q.close();
qmanager.disconnect();

| 2085 is unknown object. I'd guess that you forgot to define the queue that you want to use. If you're using runmqsc to define it, watch the case. runmqsc folds things to upper case if they aren't in quotes. |

Jigjim,
Have you looked at supportpac MS0B? It is a set of java classes for dealing with PCF commands. I think it could simplify your life.

the queue is already defined. I wanted to know if there are any specific settings (persistence, Time interval, message id etc) to be set.
I am using ms0b. I set the attributes and parameters (basically construct my command) and send it.
If I do the above code using MQ Series Client as opposed to MQ Client it works.
I therefore wanted to know if anything special has to be done for MQClient connections.
Thanks

How are you saying that.
If you have the queue then you will not get 2085.

Other than ensuring that the client connection is specified properly.

Hi,
You are correct. I was on the wrong system. I didnt have the Q defined.
I now have 3 questions:
1. Is it has to be SYSTEM.ADMIN.COMMAND.QUEUE always ? (How abt SYSTEM.CLUSTER.COMMAND.QUEUE which I already have defined)
2. I want to define a Q and a Q manager for my PCF Command. IS it possible it with some other name (rather than SYSTEM..) ?
Is there a place where I can find some more detailed documentation ?
Thanks

1.
Always SYSTEM.ADMIN.COMMAND.QUEUE
3. Look at the Programmable Command Formats and Administration Interface in the Manuals Link |

I should have been more specific to suggest that you use the PCFAgent or PCFAgentMessage class from ms0b to simplify things.
These classes do restrict you to the use of SYSTEM.ADMIN.COMMAND.QUEUE. If you want to handle your own send method, you can use a different queue. Change the "COMMANDQ" attribute of the queue manager definition to whatever queue you want, but it should be a new queue you define and not one of the other SYSTEM objects.
