Re: Hostnames or IP addresses for channel connection names

[Bullock, Rebecca (CSC)]

Kulbir - I'd vote for Hostnames because it allows you to change the IP address without needing to go in and change potentially a host (no pun intended) of definitions. Also, I think it's more descriptive (sort of like they used to say that Cobol was self-documenting). That said, be aware that this can (and has!) caused problems if the hostname propagation hasn't gotten to where it needs to get to before you try to connect.     Rebecca Bullock Computer Sciences Corporation MFCoE   Princeton, NJ  08541 email: [EMAIL PROTECTED] / [EMAIL PROTECTED]   -----Original Message----- From: Kulbir S. Thind [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 10, 2003 6:07 AM To: [EMAIL PROTECTED] Subject: Hostnames or IP addresses for channel connection names   Hi there, We have a very large network of MQSeries installations (> 300 installations) that are currently using a mixture of Hostnames and IP addresses for the channel connection names.  We are in the process of reviewing our configurations and will be looking to standardise the use of the conname attribute, either go with Hostnames or IP addresses.   Our gut feeling is to go with Hostnames as they are more descriptive of what the channel is connected to and also gives us the flexibility of being able to change IP addresses of machines without effecting channel definitions.  However, there are people in our team that seem to suggest that using an IP address rather than a hostname would significantly improve performance, is this true?  I can believe that there may be a difference in channel startup times but after that there should be no difference, is this correct? Which do people tend to use and why?
