Hi, I'm using Websphere MQ 5.3 (base product) on SunOS 5.8.
I'm trying to start a channel to itself, but it gets stuck in "Retrying" mode. I am using "127.0.0.1" for the Connection Name. I have done this exact same setup before and it worked, but there I was using MQSeries 5.2.1 CSD05 on Windows 2000.
In the AMQERR01.LOG, I see that it is trying to connect to "127.0.0.1(1414). This is not the port of my QM. Before when this worked on the Windows machines, those QM's were not on port 1414 and I had no problem.
Are there any problems with the use of the loopback address in 5.3 for Solaris, or is there some setting I can tweak, or...??? Thanks for any help. |

Your conname should be hostname(port)
like
127.0.0.1(1420) assuming your receiver QMGR's listener is running on 1420. If you do not specify anything in the port it will default to 1414. |

MQRR. That problem, and 'workaround' is for Windows boxes only. It's a known problem with Microsoft's TCP/IP stack that they refuse to fix.
Cheers,

MQRR...thanks for the ultra-fast reply! But, alas, Eddie seems to be correct. I exported MQNOREMPOOL=1 in the user's .bash_profile that starts the QM, re-executed it and restarted the QM. I got the exact same results.
Since there is no QM on this machine with port 1414 anyway, I tried manually running a listener (runmqlsr) for the QM using TCP/IP and port 1414, but it died shorly thereafter with

| AMQ9502: Type of channel not suitable for action requested. |
Eddie...IBM knows about this and hasn't put the fix in any 5.3 CSD? :-? |

The problem is a Microsoft TCP/IP problem, so IBM can't fix it in an WMQ CSD.
One of your comments has me confused:

Are you saying there is no queue manager on the machine that you want to loopback to? If so, this won't work. If you are saying that you are using a different port, you have to specify this on your MQSERVER environment variable.
The final error leads me to believe that you have your program attempting to use a channel of the wrong type. What is the name and type of channel that you are using? I would have expected you to be using a server connection or client connection channel. |

Maybe he is trying to create a SDR and RCVR on the same QMGR

| Right. The QM is on this box, and I'm creating a Sender and Receiver channel pair and XMITQ. I was just trying to copy a setup that was done on 5.2.1 on Windows. So I was surprised today when I tried the exact same thing on 5.3 on Solaris but ran into trouble. Since MQ is an IBM product, and Solaris is a Sun product, where does Microsoft come into play? |

Microsoft came into the discussion because of the MQNOREMPOOL. It is an MQ work-around to the listener pool that takes care of the Microsoft tcp/ip problem.
Also, if you are having trouble with loopback, have you tried specifying the actual hostname/ipaddress of the machine? |

Please post the channel definitions; that will enable more targeted help.
