Neil, We are using aix 5.2 with MQ 5.3.......I apologize as I do not know the minor levels at this time (I can get them in the morning).......we originally migrated of the wintel platform altogether due to the instability of the 5.2 multi-threaded listener......inetd has been awesome for stability but a recent problem where a MPE based operating system MQ client application has experienced a significant cpu increase once it was redirected from the Wintel MQ 5.3 platform to an AIX based qmgr running inetd......... Were still not sure if its due to the type listener that is being used or the platform swap in general.......we went with AIX over Wintel for availabilty but we certainly don't want to increase client cpu utilization.........

Exactly what problems have you seen and on what platforms? My site found the 5.2 threaded implementation to be less than completely reliable, but we have been extremely happy with the 5.3 implementation. The one exception to this is some exits which are used by one application to journalise the messages as they flow through the channels. The exit does not behave correctly in the threaded environment, and tends to cause failures. Because it works with the inetd based channels, the users refuse to rewrite it, so I am stuck with it. (No time or budget for me to enhance it). IBM will push the threaded listener because its performance is significantly better than the inetd implementation. This is because of process instantiation overheads which the threaded listener avoids by using a pooling process to hold the threads for multiple channels.

We have situations in which multiple channels fail when the threaded listener has problems.....never a globally impacting problem when using inetd though......to me, IBM should continue pushimng the inetd as the preferable listener for the UNIX platform........ -------------------------- Sent from my BlackBerry Wireless Handheld ----- Original Message ----- From: KEITH PARMER Sent: 07/20/2005 06:42 PM To: "MQSeries List" <[email protected]> Subject: Re: Listener; runmqlsr vs amqcrsta within the inetd.conf file Question.....is it possible to configure two different ports as listeners, one utilizing inetd and one utilizing the threaded listener? -------------------------- Sent from my BlackBerry Wireless Handheld ----- Original Message ----- From: MQSeries List [EMAIL PROTECTED] Sent: 07/20/2005 06:38 PM To: [email protected] Subject: Re: Listener; runmqlsr vs amqcrsta within the inetd.conf file Yes, the inetd.conf entry must be removed, and inetd must be refreshed. If you try to start runmqlsr without doing this, you'll get a 'port not available' error of some sort. [EMAIL PROTECTED] Sent by: MQSeries List <[email protected]> 07/20/2005 05:30 PM Please respond to MQSeries List <[email protected]> To [email protected] cc Subject Listener; runmqlsr vs amqcrsta within the inetd.conf file I have a quick question. And I don't mean to spawn any preference issues but, we have always configures our AIX boxes to start channels via inetd.conf setting. I believe that that is being replaced as a recommendation to use runmqlsr. A third party vendor is trying to deliver code to us using JBOSS and running into problems. They are asking me to start the listener via runmqlsr. I am willing to try anything but do I need to remove the entry in the inetd.conf file first? I don't have root authority and I will have to get a sys admin to do that which is a longer process.
