Does anyone know any history on the DEF LISTENER command?

I remember working with MQ on UNIX platforms and adding a line on /etc/services if I needed an additional listener port - I now see this DEF LISTENER object.

Noticed it is documented first on V6 - does anyone know why this command was created?

Is it necessary to use it - I see the listeners now have a name - or can the listeners be defined as done before?

Thx.

Yes this was if you wanted to use inetd - it's still mentioned here http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/topic/com.ibm.mq.csqzae.doc/ic13330_.htm

The runmqlsr way of doing things is more manageable and extendable than this, and so has been the preferred way of doing MQ listening for a few releases now.

You can define a listener. Before, you had to do this manually using inetd or runmqlsr, and deal with the lifetimes of these things via OS knowledge. Now MQ will manage the lifetime of listeners for you, via START LISTENER and STOP LISTENER commands.

Isn't this in the manual?

You can manage everything as before, using runmqlsr commands directly. I think you can even continue to use inetd/amqcrsta, though I don't suppose anyone would advocate that.

Thank you - yes it does look much easier this way!
