Can't work with queue manager on z/OS

Hi there,

I don't have access to z/OS but I'm wondering if it's now because
PING_Q_MGR isn't supported on MF?

http://pic.dhe.ibm.com/infocenter/wmqv7/v7r5/topic/com.ibm.mq.doc/pc13630_.htm

Are you sure the commands that fail are not of that lot?

Thank you for answer!

Yes, PING_Q_MGR isn't support on z/OS
But other command (CREATE_CHANNEL, CREATE_Q, START_CHANNEL, STOP_CHANNEL, etc.) also raise exception MQRC_SELECTOR_NOT_FOR_TYPE

But I now observed that MQ version on the z/OS system is 7.1, while on the Linux - 7.5
PyMQI supports now only command levels 7.0 and 7.5
I think it's reason of exception)

I'm really sorry to hear!

Did you perhaps have a chance to have a look at this blog post of mine?
Can your company do anything about it? This could possibly help in your
case.

Unfortunately, I have not a company. I'm student writing tool for my routine job of tech support. I just want to have one-click gui for some tasks.
But I can donate few dollars :)
I tryed to adapt 7.5 support patch for version 7.1, but I get same error.

Thanks for the offer but you know, I've just given it a second thought
and I'm wondering if it is really to do with there not being a proper
support for 7.1/7.5

Can you please post the very exact PyMQI program that doesn't work on
z/OS but does work on Linux along with an MQSC script needed to create
the objects?

My script is here: http://pastebin.com/TDSexMMj

OK, cool, so here are two other things:

- I understand you're connecting from a Linux box to z/OS. Can you make
sure MQ version on both is the same? This would mean installing 7.1 on
Linux and recompiling PyMQI.

- Are you all of the attributes you use set for MQ object in your
program are actually supported on z/OS, MQ 7.1? Isn't anything new in
7.5 or not supported on z/OS?

Yes, I connecting from Linux box.
I tried install versions 7.0, 7.1 and 7.5. And recompiled PyMQI for every version of MQ.
But every time I got exception MQRC_SELECTOR_NOT_FOR_TYPE, when I send any command to z/OS MQ.

I tried to set only required attributes (for example: MQCA_Q_NAME and MQIA_Q_TYPE for creating new queue). But I got exception again.
I got exception when even I send simple commands: MQCMD_STOP_CHANNEL and MQCMD_START_CHANNEL

But when I connection to Linux MQ, all works fine)

OK, but is it the very same MQRC_SELECTOR_NOT_FOR_TYPE exception?
Because the more I read about it the less I understand if for each
command you see the same error.

Can you please post the exact output of running this program? The exact
traceback?

Yes, for each command I get same MQRC_SELECTOR_NOT_FOR_TYPE exception

For example:

# test_mq.py

import pymqi
import CMQC

queue_manager = "LDT3"
channel = "SYSTEM.ADMIN.SVRCONN"
host = "13.99.120.170"
port = "1511"
conn_info = "%s(%s)" % (host, port)

queue_name = "MYQUEUE.1"
queue_type = CMQC.MQQT_LOCAL
max_depth = 123456

args = {CMQC.MQCA_Q_NAME: queue_name,
        CMQC.MQIA_Q_TYPE: queue_type,
        CMQC.MQIA_MAX_Q_DEPTH: max_depth}

qmgr = pymqi.connect(queue_manager, channel, conn_info)

pcf = pymqi.PCFExecute(qmgr)
pcf.MQCMD_CREATE_Q(args)

qmgr.disconnect()

> python test_mq.py
Traceback (most recent call last):

    raise MQMIError(rv[-2], rv[-1])

Hmm... I think I have a bad news for you.

See, PyMQI uses MAQI to implement PCF commands. MQAI is a wrapper for
PCF which really simplifies MQ programmer's life. The trouble is, the
documentation explicitly says MQAI is not supported on z/OS

http://pic.dhe.ibm.com/infocenter/wmqv7/v7r5/topic/com.ibm.mq.doc/pc15450_.htm

"""
The MQAI is a programming interface to WebSphere® MQ, using the C
language and also Visual Basic for Windows®. It is available on
platforms other than z/OS®.
"""

So I'm afraid MF is showing its age here.

Really sorry for all the commotion but I just don't have access to z/OS.
Otherwise I would've tested it myself earlier to save you all the troubles.

Thank You for answer!
Then I will search other way for my tasks :)

I've just released PyMQI 1.3 and the development effort has moved to GitHub - https://github.com/dsuch/pymqi
