Hello,
I am not that familiar with how MQ client work but I know the information for the svrcn channel get stored in the channel table. I can't start one of the svrcn channels and when I look in the *.TAB file on the client side , I noticed an issue there . My question is , how does this file get generated and Is it possible to modify it manually? thanks

| Entries are added to AMQCLCHL.TAB when you define CLNTCONN channels on the queue manager. You can copy the file to the client. For SVRCONN channels, set the MQSERVER environment variable. |

Entries are added to the client channel table when a CLNTCONN channel definition is created on a queue manager. NB. the file is associated with the queue manager, and is in its directory structure. You can take a copy of this file and place it on a client machine. The client code can then read this table. Details are documented fully in the MQ Clients manual. Check the 'documentation' link at the top of this page.
EDIT: Sorry it appears I repeated KramJ's basic information  I just tried to delete this post but couldn't.

if by that, you mean "using something like notepad or emac", the answer is "no!". The file is a linked list of channel definitions and if you edit it, you'll probably mess up the linkage.....

There is a perl program somewhere which deconstructs the client chanel table into a readable form, and builds it again.

sounds dangerous, where is the program?
I wrote a short "c" program to dump the key fields of the channel table, cause i was always wondering which definitions my mq client was picking up....
