Hi,

I am using the below code to put a PCF Command on the Client. I am not able to see the message on any Q's on mainframe. The error log on mainframe shows the follwing lines:

Code:

17.42.28 STC00700 +CSQX208E &MQO1 CSQXRESP Error receiving data, 683
683 channel SYSTEM.DEF.SVRCONN,
683 connection 104.154.69.132
683 (queue manager ????)
683 TRPTYPE=TCP RC=00000461
17.42.28 STC00700 +CSQX599E &MQO1 CSQXRESP Channel SYSTEM.DEF.SVRCONN ended ab

Can somebody pls help me with this? Do I need set the Msg Charachter set so that the system Q understands the command and sends appropriate reply to the reply Q.

Thanks Jigs

Code:

public class PCFClient_Trial {
public static void main (String [] args) {
   System.out.println("*** In PCFClient_Trial ***");
   MQQueueManager qmgr;
   MQQueue sendQ, replyQ;
   MQPutMessageOptions pmo = new MQPutMessageOptions ();
   MQGetMessageOptions gmo = new MQGetMessageOptions ();
   MQMessage sendM, recvM;
   String name = null;
   Integer depth = null;
   String replyQueueName = "MQO1LV5.QL.ICRS_TO_XRM";

int [] attrs = { CMQC.MQCA_Q_NAME, CMQC.MQIA_CURRENT_Q_DEPTH };
   MQCFH cfh;
   PCFParameter p;

   System.out.print ("Connecting to queue manager at " +
      args [0] + ":" + args [1] + " over channel " +
   args [2] + "... ");
   MQEnvironment.hostname = args [0];
MQEnvironment.port = Integer.parseInt (args [1]);
   MQEnvironment.channel = args [2];

   MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY,
                     MQC.TRANSPORT_MQSERIES);

   try {
      qmgr = new MQQueueManager ("MQO1");
   System.out.println ("Connected to: " + qmgr.name);

      String a = qmgr.getCommandInputQueueName();
      System.out.println("Command Q for MQO1 is : " + a);

      // MQC.MQOO_OUTPUT
      // MQC.MQOO_INPUT_AS_Q_DEF
   // MQC.MQOO_INPUT_SHARED
   // MQC.MQOO_INPUT_EXCLUSIVE

int openOptions = MQC.MQOO_OUTPUT ;

// SYSTEM.CLUSTER.COMMAND.QUEUE
// SYSTEM.DEFAULT.LOCAL.QUEUE
// SYSTEM.COMMAND.INPUT
   sendQ = qmgr.accessQueue(
         "SYSTEM.COMMAND.INPUT",openOptions,null,null,"");

   sendM = new MQMessage();
   // message.writeUTF("Hello World!");

      sendM.messageType = MQC.MQMT_REQUEST;
      sendM.characterSet = 37;
      // sendM.
      sendM.expiry = 100;
      sendM.feedback = MQC.MQFB_NONE;
      sendM.format = MQC.MQFMT_ADMIN;
      sendM.replyToQueueManagerName = "MQO1";
      sendM.replyToQueueName = replyQueueName;

      MQCFH.write (sendM, CMQCFC.MQCMD_INQUIRE_Q, 3); // 3 parameters follow
   MQCFST.write (sendM, CMQC.MQCA_Q_NAME, "*");
   MQCFIN.write (sendM, CMQC.MQIA_Q_TYPE, CMQC.MQQT_ALL);
   MQCFIL.write (sendM, CMQCFC.MQIACF_Q_ATTRS, attrs);

   System.out.print ("Sending PCF request... ");
   sendQ.put(sendM, pmo);
   System.out.println ("Sent.");

Based on the error part, that's z/OS you're trying to connect to. Guess what, z/OS doesn't support PCF messages.

Take a look at the PCF manual for how you "talk" to z/OS remotely. You send in "clear text" commands, and parse out "clear text" replies. Fun.

But, that's not you're problem. I'm not sure what is though. Do you have the CAF installed.

Cheers,

Yes, again, you can't use PCF messages against a Z/OS queue manager.

You have to put MQSC commands onto the command queue.

There's nothing to investigate.

You put the MQSC command into the body of the message, and put it on the queue.

Hi,

Does the below code look correct? I am more of a java programmer then a MS Series guy and so am having difficulty in MQ stuff ..

Thanks

Jigs

Code:

public class MQSCClient {
public static void main (String [] args) {
   MQQueueManager qmgr;
   MQQueue sendQ, replyQ;
   MQPutMessageOptions pmo = new MQPutMessageOptions ();
   MQGetMessageOptions gmo = new MQGetMessageOptions ();
   MQMessage sendM, recvM;
   String replyQueueName = "MQO1LV5.QL.ICRS_TO_XRM";

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

   MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);

   try {
      qmgr = new MQQueueManager ("MQO1");
   int openOptions = MQC.MQOO_OUTPUT ;

sendQ = qmgr.accessQueue("SYSTEM.COMMAND.INPUT",openOptions,null,null,"");

   sendM = new MQMessage();
   sendM.writeUTF("DISPLAY QMGR");

   sendM.messageType = MQC.MQMT_REQUEST;
   sendM.expiry = 100;
   sendM.feedback = MQC.MQFB_NONE;
   sendM.format = MQC.MQFMT_ADMIN;
   sendM.replyToQueueManagerName = "MQO1";
   sendM.replyToQueueName = replyQueueName;

   System.out.print ("Sending PCF request... ");
   sendQ.put(sendM, pmo);
   System.out.println ("Sent.");

   replyQ = qmgr.accessQueue (replyQueueName, MQC.MQOO_INPUT_EXCLUSIVE, "", "", "");

   gmo.options = MQC.MQGMO_WAIT | MQC.MQGMO_CONVERT ;
   gmo.waitInterval = 1000;
   recvM = new MQMessage();
   recvM.messageId = sendM.messageId;

   replyQ.get(recvM, gmo);
   String msgText = recvM.readUTF();
   System.out.println("The message is : "+msgText);
   sendQ.close();
   replyQ.close();
   qmgr.disconnect();
   }
   catch (MQException mqe) {
   if (mqe.reasonCode != MQException.MQRC_NO_MSG_AVAILABLE) {
         System.err.println (mqe);
   }
   }
   catch (IOException ioe) {
   System.err.println (ioe);
   }
}
}

From one of the different posts in the forum:
WriteUTF method puts additional stuff on the queue.
Check the other methods for writing text. Try using one of those.

Good luck

F.J.
