12.5 SU3 is Out - Important change (IMO)
Some may have heard of the work to help make performance better and here's a neat little caveat for the new HAProxy for Tomcat:

"Restart of the Cisco TFTP service will temporarily result in the unavailability of the web services up to 10 seconds on that node where HAProxy undergoes restart."

I know at least in my environments I restart TFTP during business hours when necessary. Need to think about that more in smaller environments since now you could be turning off AXL and such briefly.

And the 911 Route Pattern annoyer...err.. I mean reminder. I have yet to
experience it, but it reads like you simply check a box to acknowledge that
you know what you are doing, just in case your 911 pattern is a DN for CER
or an XLATE to avoid secondary dial-tone issues.

It's just there, you don't need to do anything with it. The link Matt
posted has a description and a graphic.

"HAProxy is a fast and reliable solution that offers high availability,
load balancing, and proxy capabilities for HTTP-based applications. With
this release, HAProxy frontends all the incoming web traffic into Unified
Communication Manager and IM and Presence Service."

Re: 12.5 SU3 is Out - Important change (IMO) [ In reply to ]
The latter it’s software inside each server. You can’t do anything with it it’s just there.

You may need to follow different commands to restart Tomcat now? Not sure and didn’t see anything about that.

UCCX introduced something like this too, just not the brand HAProxy, and I
think it's only front-ending Finesse, and not AppAdmin.

The latter it’s software inside each server. You can’t do anything with it it’s just there.

You may need to follow different commands to restart Tomcat now? Not sure and didn’t see anything about that.

I can’t find any feature documentation. Is this a new thing that we can take advantage of by configuring multiple servers or something? OR is it just backend stuff that I don’t have to worry about nor can I configure?

Some may have heard of the work to help make performance better and here’s a neat little caveat for the new HAProxy for Tomcat:

“Restart of the Cisco TFTP service will temporarily result in the unavailability of the web services up to 10 seconds on that node where HAProxy undergoes restart.”

I know at least in my environments I restart TFTP during business hours when necessary. Need to think about that more in smaller environments since now you could be turning off AXL and such briefly.
