Hi all

I have a quick question about amqsputc in /opt/mqm/samp/bin

I run it with amqsputc <QUEUENAME> <QMGR>. How does it figure out which client connection channel to use? I have 3 client connection channels and it looks like it tries to use at least 2 of them??

Thanks

I believe there is a discussion in the clients manual on how things are found in the table.

The easiest way to get this to work is to set up an environment variable
called MQSERVER. Set it to something like this:

SET MQSERVER=SYSTEM.DEF.SVRCONN/TCP/hostname (port)

the first part if the name of a 'svrconn' channel, the second is
the protocol used, and the third is the 'connection name'
consisting of either an ip address or hostname or dsn name,
followed by the port number. By default, MQ uses 1414.


Hope, this will help

Hi,

It uses whatever you have set for MQSERVER. (or MQCHLTAB & MQCHLLIB).

All true, but it's not a good idea to use the SYSTEM objects or the default ports.

Also not compatable if the poster has already got 3 possible channels to use, especially if they're on 3 different boxes!

Thanks for all the replies. I am not using MQSERVER. I am using MQCHLTAB and MQCHLLIB. The process itself works fine (well I am getting an SSL problem and thats what I am trying to figure out but it works fine for non-SSL). I was just curious as to how it figures out which client connection channel it uses. Looks like it uses 2 channels out of 3 in there...one custom channel I created and also SYSTEM.DEF.SVRCONN(CLNTCONN)

Thanks

If you use CONNX, that will override everything.

If you set MQSERVER, that will override everything else for client.

If you don't set MQCHLLIB or MQCHLTAB, it will look for the AMQCHCHL.TAB in the top installation directory. If you set either of those, then it will look for what and where you told it.

If it finds a valid CCDT, it will always use the first channel (for the specified QMGR) lexically in order what works (likely the first one).

Here's the link to this and more:

Hmmm, SSL. Be sure to only create/modify the CCDT with the runmqsc command and not MO72 (mqsc -n). Well, you can use the MQ Explorer too.

WebSphere MQ searches the client channel definition table, in alphabetic channel name order, looking in the queue manager name (QMNAME) field for an entry corresponding to the one given in the MQCONN call.

Peter,

It does say Alphabetical, but the channel name is not composed only of the letters of the alphabet so that makes it lexical.

Quote:
Lexical order refers to how string values are compared, which is basically alphabetical order (or dictionary order) with a slight twist. Whitespace comes first in the alphabet, then symbols . Next are digits , then capital letters , and then lower-case letters .


If I were a bet'n man, I would say it is the lexical order of your code page.
