Hi,
We have just installed MQ V6 on our Mainframe. I tried my monitoring programs since I have read that MQ on z/OS is now also able to handle PCF command. Processing the command seems to work, but there is a Problem with converting the the reply MQMessage into a PCFMessage.
| Code: |
// Wait for answer
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.options = MQC.MQGMO_WAIT | MQC.MQGMO_CONVERT;
gmo.waitInterval = _maxReplyDelay;
Vector answers = new Vector();
MQMessage replyMsg = new MQMessage();
inQ.get(replyMsg, gmo);
answers.add(new PCFMessage(replyMsg));
....
|
The "new PCFCommand(replyMsg)" does throw the following Exception:
| Code: |
com.ibm.mq.MQException: MQJE001: Beendigungscode 2, Ursache 3001
at com.ibm.mq.pcf.MQCFH.initialize(MQCFH.java:138)
at com.ibm.mq.pcf.MQCFH.<init>(MQCFH.java:113)
at ...
|
I browsed the reply message and decompiled the class com.ibm.mq.pcf.MQCFH and have seen that the first number [first getInt() returns 17 (see below)] seems to be the problem:

Where are you sending these PCF messages from (what platform)?

Sending from Windows 2000 to z/OS MQ V6.0 Queue Manager to the SYSTEM.COMMAND.INPUT queue and reading the reply from a dynamic queue.
Actually it seems that sending PCFMessage request, processing and receiving PCFMessage reply worked  |

No the conversion of the MQMessage which I receive as reply into a PCFMessage does not work. The exception mentionend in my first post gets thrown! So may something with the format of the message is wrong. |

Thanks, that must be the problem, because yes I am using MS0B.
But how can I call PCF commands from my Java program? Is there no Java API available for PCF to z/OS? |

| Actually I thought that I could use the same PCF Java programs to send requests to our Solaris QMs and to our z/OS QMs. Isn't that the case? |

What exactly do you mean? If MS0B supported the required zOS PCF command, then YES.... why not?
For example, saveqmgr can inquire on unix, windows, os/400 and zOS qmgrs and its one program..... (but its a contact admin old "c" program)
Of course... the "contact admin" other option is to send a "MQSC" command to the zOS command queue (ie: DISPLAY Q(xxx)....). There are other supportpacs that work this way....
