| Is there a way to get the IP addresses of the readers and writers connected to a particular queue? |

Do a Queue Status command from runmqsc on the queue in question.

Is this information available in the java MQ API? |

Hi,
Use the Java MQ PCF classes - SupportPac MS0B.
Regards,
Roger Lacroix |
Thanks Roger. I downloaded SupportPac MS0B and tried one of the examples. I got an error- Reason code 3001, but can't find this error code in IBM's manual. Is there a seperate manual for PCF specific error codes?
thanks,
Paul |

Use mqrc to get quick info:
mqrc 3001
3001 0x00000bb9 MQRCCF_CFH_TYPE_ERROR
More details are in the WMQ Programmable Command Formats and Administration Interface manual:
3001 (X'0BB9') MQRCCF_CFH_TYPE_ERROR
Explanation: Type not valid.
The MQCFH Type field value was not valid.
Programmer Response: Specify a valid type. |

Hi,
Are you sending PCF commands to the mainframe (OS/390 or z/OS) ??
MQ on the mainframe does NOT support PCF commands (at least not until v6  ). You must send plain text commands.
Regards,
Roger Lacroix

Roger -
Unfortunately, the information he is trying to get is exactly the information that you and I have been discussing, that seems not to work from MS0B.
That is, right now, Roger and I are working with the developer of MS0B to resolve a bug with using MQIACF_Q_HANDLE. All you get back is an empty response, because the code doesn't actually allow you to set MQIACF_Q_HANDLE.

Roger,
Yes, I sending to the mainframe, so I guess I'll have to wait for v6.

Roger,
Are you saying that it doesn't work on the mainframe? Or doesn't work for all platforms? I would also be interested in getting this info from Solaris based systems also.
thanks,
Paul |

Z/OS queue managers do not support PCF messages. They only support messages that contain MQSC commands in plain text.
MS0B only supports PCF messages, so you can not use it with z/OS queue managers.

Hi paulic,
As per Jeff's comments, this is what I was referring to.

Jeff,
I got the DISPLAY QSTATUS to work with PCF on a Solaris system running MQ 5.3, but I couldn't get it to work on a mainframe by sending plain text MQSC commands from a java program. I couldn't get any plain text command to work. I tried sending plain text MQSC commands to a mainframe (MQ 5.3) COMMAND_INPUT_QUEUE but could not read the reply messages from the reply queue. If I step through the program in debugger, I see 3 messages on the reply queue right after sending the DISPLAY command, but the get command times out with reason code 2033(no message available). Any Idea why I cant read the replies? |

Hi,
Did you forget to clear the MsgID & CorrelID fields BEFORE doing the get. Or are you sure you are reading the right queue?
3 messages - sounds like you got an error from the z/OS queue manager's command server. Because, it always sends a header and trailer messages - minimum of 2 messages.
Regards,
Roger Lacroix

Hi Roger,
Thanks Roger. I had a typo in specifying the queue on the open.
thanks,
