AMQ9213 2009 MQRC_CONNECTION_BROKEN on IBM MQ clients - Middleware News


You have WebSphere MQ clients which connect to several different MQ servers. The MQ clients are quite frequently disconnected with rc=2009, MQRC_CONNECTION_BROKEN. The clients are able to reconnect immediately. The queue managers are running well. You see no problems when issuing 'runmqsc' commands on the server.

Symptom

On the MQ server side you see the following message in the queue manager's error log, AMQERR01.LOG:

AMQ9213: A communications error for TCP/IP occurred.
EXPLANATION: An unexpected error occurred in communications.
ACTION: The return code from the TCP/IP(select) [TIMEOUT] 660 seconds call was 11 (X'B'). Record these values and tell the systems administrator.

Cause

There was a parameter recently added in your qm.ini file called ClientIdle that was set to 600 secs. This caused the client connections to end after they were idle for the specified period of time + 60 seconds. After the connection is terminated at the server, the next attempt to send a request from the client side results in rc=2009.

Resolving the problem

You can either remove the ClientIdle parameter from the Channels stanza of your qm.ini files or you can set it to a value, which is higher than you expect your clients will be idle between calls. 
The default path for the qm.ini file is /var/mqm/QMGRs//

IBM WebSphere MQ – Common install/uninstall issues for MQ Version on Windows - Middleware News

Creating a log file when you install or uninstall WebSphere MQ WebSphere MQ for Windows is installed using the Microsoft Installer (MSI). If you install the MQ server or client through launchpad , MQPARMS or setup.exe , then a log file is automatically generated in %temp% during installation. Alternatively you can supply parameters on the installation MSI command msiexec to generate a log file, or enable MSI logging system-wide (which generates MSI logs for all install and uninstall operations). If you uninstall through the Windows Add/Remove programs option, no log file is generated. You should either uninstall from the MSI command line and supply parameters to generate a log file, or enable MSI logging system-wide (which generates MSI logs for all install and uninstall operations). For details on how to enable MSI logging, see the following article in the WebSphere MQ product documentation: Advanced installation using msiexec For details on how to enable system-w
