Hi, I am trying to set a queue parameter using PCF under JMS.
| Code: |
agent = new PCFMessageAgent ( "localhost", 2415, "MY.SVRCONN" ) ;
System.out.println ( "+++ Connected" ) ;
// Build the request
(1) request = new PCFMessage ( MQConstants.MQCMD_CHANGE_Q ) ;
(2) request.addParameter ( MQConstants.MQCA_Q_NAME, "QL.IN" ) ;
(3) request.addParameter ( MQConstants.MQIA_Q_TYPE, MQConstants.MQQT_LOCAL ) ;
(4) request.addParameter ( MQConstants.MQIA_INHIBIT_GET, MQConstants.MQQA_GET_INHIBITED ) ; // set GET(DISABLED)
(5) request.addParameter ( MQConstants.MQIA_CLWL_Q_PRIORITY, 3 ) ; // set priority
// request.addParameter ( MQConstants.MQCA_Q_DESC, "New Descr" ) ; // set description
|
If I have only (1) and (2), I get rc=3019, ok
With (1) + (2) + (3), I get rc=3015, STRING Parameter Error
What String is wrong ???
(1)+(2)+(4) = 3014 = INTEGER parameter error
(1)+(2)+(5) = 3014 = INTEGER parameter error
(1)+(2)+(6) = 3015 = STRING parameter error
What tools shall I use to read the parameters received to determine why they are invalid ?
A MQ Trace ?
===
Parameters must be :
http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=%2Fcom.ibm.mq.csqzac.doc%2Fpc11160_.htm
// required :
// QNAME (MQCFST)
// QTYPE (MQCFIN) := MQTT_LOCAL ;
So, what STRING is not valid ? The queue name ?? |

PCF does not really work well under JMS. It follows a kind of stand alone / java pojo model.
Can you please elaborate what you are doing with the request when trying to send it?
Have fun

There doesn't appear to be any JMS used at all.
The PCFMessageAgent handles all of the connections, and handles the sending and receiving of messages.
The only string that could be wrong in the combo of 1,2,3 is the queue name. It's the only string there is...
An MQ client trace should probably show you the message data you're building, or you can look at just writing the message directly to a queue (other than the Command Server queue). |

What I am trying to do is to change (MQCMD_CHANGE_Q) any parameter of the queue, as
*) PUT(DISABLED/ENABLED)
*) CLWLPRTY(0 lowest .. 9 highest)
*) Description(text)
I have PCF samples from
1) MQ - \\MQ\tools\pcf\samples
2) MS0B - º\ms0b\com.ibm.mq.pcf
Right now the PCF is running in an Eclipse environment
(import com.ibm.mq.pcf.*  ,
but it shall end up in a MB flow Java node.
The connection is done using a SVRCONN channel.
I agree in (1)+(2)+(3) there is only one string, this is, the queue name.
I have changed the string literal to "QLIN" and now get mqrc 2085, object does not exist, which is fine. Maybe the dot (".") was the problem. Now I create a queue "QLIN" and get mqrc 3015 again.
Lets run a MQ trace ...
Tx. Sebastian. |

If you think the "." was a problem have you tried escaping it?

Hi -> tgif, uf
1) I dont know how to escape the dot, sorry, but ...
2) I tried using QLIN as queue name and got 3015 again (already written in my previous post).
As T Rob says in
>>> http://stackoverflow.com/questions/4688919/error-creating-queue-with-websphere-mq-api
... the order of the sentences is important when using PCF.
So, I think there is a sentence missing before providing the queue name ... I am just guessing. I am using AMQSCLMA.C as source, and dont see it.
Thanks. Sebastian. |

AMQSCLMA.C resum :
| Code: |
.
PCFMsgLen = buildChangeQPCF(pAdminMsg,
AdminMsgLen,
DefnLQ.QName,
TargetCLWLPRTY,
TargetCLWLUSEQ);
.
pPCFHeader->Command = MQCMD_CHANGE_Q; /* "Change Queue" */
pPCFString->Parameter = MQCA_Q_NAME;
strncpy( pPCFString->String, QName, MQ_Q_NAME_LENGTH); /* Specify queue */
pPCFInteger->Parameter = MQIA_Q_TYPE ;
pPCFInteger->Value = MQQT_LOCAL;
pPCFInteger->Parameter = MQIA_CLWL_Q_PRIORITY;
pPCFInteger->Value = TargetCLWLPRTY;
pPCFInteger->Parameter = MQIA_CLWL_USEQ;
pPCFInteger->Value = TargetCLWLUSEQ;

So I am still in darkness .. |

Hi again. I did run MQ trace.
In 3 seconds, I got

25 File(s) 3.356.426 bytes |
Of course I will try ro read it as simple text .... but maybe my clever coleagues have a better way to read a MQ trace ...
Is there any tool analyzing the 25 files at once and resuming the errors it finds ?
Sebastian. |

PCF stuff is a PITA to get right.
In the past I try it out outside of broker until I:-
1) Get the sending message right
2) Am able to get a non error reply.
Then I set some very unique values in the data I need to retrieve using PCF. Then I can analyze it by looking at the data on the specified reply queue.
When that is correct, I can then get broker to send the correctly formatted request and because I have a sample reply message I can code and test the code that handles it.
So for a Queue Depth problem I'd put a load of messages on the queue, say 1077 (Or a hex data pattern that is easy to find in a message dump).
When it seems to work, read a message and see if you get back the updated QD value.

In fact, I did try to find "3015" in *.TRC and failed.
Then, I remembered few months ago I discovered those traces had the RC's in HEX, so I searched for 0xBC7, with no success.
Need more clues.
Or a weekend to rest.
Enjoy.
Sebastian. |

did you look at the java pcf samples provided with the product in \tools\pcf ? I saw you were using the C sample...

Hi, Michael and Jeff.
Yes, I've been thru PCF samples, but they are "inquiry" only. There is no one to "change" the queue values :
| Code: |
Directory of c:\MQ\tools\pcf\samples
5.979 PCF_ChannelStatus.java
11.363 PCF_ClearQueue.java
10.891 PCF_CommonMethods.java
6.112 PCF_CreateChannel.java
5.904 PCF_CreateQueue.java
4.612 PCF_DeleteChannel.java
4.415 PCF_DeleteQueue.java
9.705 PCF_DisplayActiveLocalChannels.java
7.730 PCF_DisplayActiveLocalQueues.java
16.640 PCF_DisplayConnections.java
7.568 PCF_ListQueueNames.java
4.524 PCF_StartChannel.java
4.515 PCF_StopChannel.java
9.076 PCF_WalkThroughQueueManagerAttributes.java |
No "MQCMD_CHANGE_Q" in any *.java ...
The most "similar" is PCF_CreateQueue.java :
| Code: |
pcfCM.CreateAgent(args.length);
int queueType = MQConstants.MQQT_LOCAL;
// Create the PCF message type for the create queue.
// NB: The parameters must be added in a specific order or an exception (3015) will be thrown <<< interesting comment !
PCFMessage pcfCmd = new PCFMessage(MQConstants.MQCMD_CREATE_Q);
// Queue name - Mandatory.
pcfCmd.addParameter(MQConstants.MQCA_Q_NAME, PCF_CommonMethods.pcfQueue);
// Queue Type - Optional.
pcfCmd.addParameter(MQConstants.MQIA_Q_TYPE, queueType);
// Add description.
pcfCmd.addParameter(MQConstants.MQCA_Q_DESC, "MyQueue");
|
Shall play with it this weekend ...
Sebastian. |

Yes, this one does it (CHANGE_Q) :
| Code: |
| MQMessage[] pcfResponses = agent.send(CMQCFC.MQCMD_CHANGE_Q, parameters); |
Obviously you are better with Google than me, or have more patience !
Thanks, Michael. I'll try it this weekend.
