Hello!

Does anybody have experience at Linux to connect WAS to queue managers using CCDT file. I tried to do test connection in WAS connection factory and I received RC 2278. In CCDT file is only one queue manager.
The same CCDT file is used at my PC. I tested CCDT file using amqsputc and runmqsc -c commands. Without any problem I was succesfully connected to the qmgr with runmqsc -c and amqsputc.

Does anybody have idea what to do here to connect WAS to qmgr using CCDT?

Regards

Remember the CCDT is a BINARY file
Make sure your path to the CCDT file is absolute.
What does your WAS error log show for the connection attempt?
What is your current setup for the CCDT:

Code:

runmqsc -n <CCDTfile>
dis chl(*) all
end

Yes, the CCDT file is download binary to WAS Linux server.
Yes, the path for CCDT file is specified absolute at WAS.
In connection factory after connection attempt RC=2278 is showed.
Is there any WAS log where more messages can be found for connection attempt?

My current setup for CCDT is as follows:

D:\>runmqsc -n
5724-H72 (C) Copyright IBM Corp. 1994, 2022.

How are you defining the connection factory to WAS?
Did you check that you could connect correctly using amqscnx and the CCDT?

I configured a connection factory for the WebSphere MQ messaging provider.
I had to select the connection method. The options are to use a client channel
definition table or to enter all the connection information via the wizard.
I selected CCDT. I was asked to provide the client channel definition table URL
and queue manager name.

The URL for the CCDT is:
file:///absolute_path/AMQCLCHL.TAB
After this I performed a test connection which failed.

I tested connection from my PC using these commands to test CCDT is it correct:

SET MQCHLLIB=CCDT_directory_path
SET MQCHLTAB=AMQCLCHL.TAB

amqsputc QUEUE_NAME QMGR_NAME
runmqsc -c QMGR_NAME

All works fine and I was connected.

I have never used amqscnx to check connectivity. I cannot find amqscnx.

I found in samp directory this:

amqscnxc [-x ConnName [-c SvrconnChlName]] [-u User] [QMgrName]

Do you suggest to use this command to check that I could connect correctly using amqscnxc and the CCDT?

Yes set the CCDT variables. Make sure there is not MQServer variable defined and use

Code:

amqscnxc [-u user] QMgrName

If you can connect this would mean the CCDT is right and you have to review how to define it to WAS. (You might have to go to the custom dialog).

I tried with amqscnxc and connecting to the queue manager was successful.

SET MQCHLLIB=CCDT_directory_path
SET MQCHLTAB=AMQCLCHL.TAB

D:\>amqscnxc QMGR_NAME
Sample AMQSCNXC start
Connecting to queue manager QMGR_NAME
with no client connection information specified.
Connection established to queue manager QMGR_NAME
Sample AMQSCNXC end

After I checked CCDT file, I specified in WAS panel:

file:///CCDT_directory_path/AMQCLCHL.TAB

queue manager: QMGR_NAME

I made connection test in WAS connection factory but I received RC 2538.
Does anybody have idea what to do here?
