[cisco-voip] using "utils dbreplication setrepltimeout" as part of jump upgrade

[Brian Meade (brmeade)]

Lelio,

You want to always have that set.  It really only matters on the publisher.  It’s a timer for how long it gives to define nodes before it does the broadcast to those nodes.  If your timer is too short, you may end up doing multiple broadcasts to subsets of nodes.  It really just makes replication more efficient.

Thanks Brian and Adam. This is great.

I didn't read anything specific about upgrades in that document, so I re-read the upgrade guide. When I read it the first time, it sounded like it was more geared towards the upgrade activity, not the size of the cluster. But after re-reading it, it makes a bit more sense now.

We have 6 servers in our cluster, so the math works out to  [ (5*1)+(1*2) ] * 60 = 420 sec.

The question is, should this be the setting during normal operation as well? It certainly sounds like it.

Use the guidelines here to set the repltimeout:

The jump upgrade documentation <https://supportforums.cisco.com/servlet/JiveServlet/download/35163-6-15369435/Drive_to_Nine_Jump_upgrade_versions_4.1.3-7.1.5_to_9.1.2-3%5B1%5D.pdf> refers to using "utils dbreplication setrepltimeout", however it doesn't give a recommendation as to how much to increase this by. It also doesn't mention how to find out what the current setting is, only what the default is.

Just wondering what the recommended number to increase this by is. Also, any way to find out what the current value is?

Thanks!
