Are there any known TCP/IP problems with MQ 5.3 installtions ?
I cannot get my MQ 5.3 cluster to work due to TCP/IP channel problems.
MQ V5.2.1 was working just fine in same environment ....
Description
-----------
- Installed Websphere MQ 5.3 on Win2k machine.
- Defined Queue Manager 53A - NO PROBLEM
- Defined Queue manager 53B - NO PROBLEM
- Defined CLUSTER53 with Cluster sender/receiver channels between 53A and 53B
- But ... Cannot get cluster sender channels to run, they remain in "retrying" state with following errors (as reported in 53A logs):
<install dir>\Qmgrs\53A\errors\AMQERR01.LOG:
---------------------------------------------
AMQ9208: Error on receive from host M052825 (127.0.0.1).
EXPLANATION:
An error occurred receiving data from M052825 (127.0.0.1) over TCP/IP.
This may be due to a communications failure.
ACTION:
The return code from the TCP/IP (recv) call was 10053 (X'2745'). Record
these values and tell the systems administrator.
C:<install dir>\Errors\AMQERR01.LOG:
----------------------------------------
07/08/2002 16:52:29
AMQ9213: A communications error for TCP/IP occurred.
EXPLANATION:
An unexpected error occurred in communications.
ACTION:
The return code from the TCP/IP (ioctlsocket) call was 10038 (X'2736').
Record these values and tell the systems administrator. |

Yes it is ...
This is a test environment on my laptop, and I usually go with the loopback address to avoid DHCP issues when I'm plugged into a LAN somewhere. |

The problem is described by MS knowledge base article Q319952, and only applicable to 5.3.
Resolution:
Set the environment variable MQNOREMPOOL to the value
1 using the "System" section of the environment variables panel
in the "System" control panel app, then reboot and retry the
test. |

gflaifel,
That's a pretty neat solution. Do we know what MQNOREMPOOL does? Is it documented somewhere? |

The environment variable controls the channel process pooling function according to the WMQ Change Team at Hursley ...

Got the same error on Win XP. Setting MQNOREMPOOL works. Didn't have to restart. Recycled TCP and MQ in the services. |

Posted here to notify those on this thread too...
Yes, Funnily enough I started seeing this recently. I think I have narrowed down a piece of software I installed which is causing the problem.
Can you, on your server, get process explorer (www.sysinternals.com), run it, select the listener (runmqlsr) in it, Change lower pane view to DLLS, and View->Select Columns->Dll tick the box 'Path'.
Then pm me the list of dlls please (file -> save as). I'd appreciate the same from anyone who hits the 10038 error without MQNOREMPOOL set.
Setting MQNOREMPOOL in the system portion of the env vars and rebooting will work around the problem for now. I'd like to identify the cause and start getting it addressed! |

Can you tell us what CSD you are running in your W2K environment?
