[cisco-voip] CCM Failover PUB-SUB Process

[Jim McBurnett]

Hi folks,
Been a long time since I posted.
And I am looking at a failover that occurred / did not occur as expected and the aftermath with a PUB/SUB
The system did not failover as I would have liked, but I have yet to get the crash dump off the server.
The system has a PUB/SUB- IPCC, and Presence and Unity (all Version 7).
It looks, to me, that the end user started a process that took 74% of the system with 24% of the system running calls etc..
And the handshakes between pub and sub got intermittent, the phones just were confused and the PUB crash dumped...

I would like to look at this a little closer......
To that end, does anyone have a DOC on what happens with failover in a step by step?
I found this:
http://www.cisco.com/en/US/docs/voice_ip_comm/uc_system/UC5.0.2/ipt_system_arch/UC05_FFR.html
But would like more...

SDL LINK out of service- then xxxx.
Phones register....
What tests prompt the failover?
What won't?
What are the time lines?


I will be opening a TAC case, but just don't see the sense for a TAC engineer to hold an open case right now until I can get him/her the crash dump file.....


Thanks,
Jim
