Hey all, I am a JMS newbie and I'm trying to get the Multi-instance connection string to work. It works fine until it gets to the last host in the list. For some reason, it doesn't recognize that I'm using a different port and adds (1414) to the connection string...

Of Course, it bears mentioning, if I move the Multi-Instance queue manager to one of the other servers, OR, move the Hostname4(64308) to another position, it connects right up and sends the messages.

My connection string from the XML file looks like this...
<property name="hostName" value="Hostname1(64308),Hostname2(64308),Hostname3(64308),Hostname4(64308)"></property>


Please see Errors and where I highlighted the problem below...

Please provide further detail on this.

The original issue suggests that you just need to remove the port # from the hostname list and put it in the port number directly.

But the fact that "the same" configuration works on other machines or with partial hostnames in different places, means that the problem is something else entirely.

Right, I can get it to work... The problem is that the JMS code seems to recognize the port for all the hosts in the list, but Adds the default port at the end of the string for the last host in the string.


Hostname4.subdom.com(64308)(1414)

If it can connect on any of the previous hosts, it obviously wouldn't continue down the list.

Right, okay.

That suggests that it's not treating this list of names as a list of names that includes a port #, and is always including the port# at the end. I.e. it's not treating it as a list of names, but merely a single hostname.

Try adding multiple
Code:
<property name="hostName" value="hostname1"></property>
tags, and then set the portNo property to 64308.
