Title: Cold Stand By Concept
Post by: Shooter on September 10, 2015, 11:27:48 AM

What is "Cold Stand By" concept in genesys and which application supports this stand by mode? I am unable to find any defination in genesys doc.

Cold Standby is a collection of Server components which remain non-operational until started and configured, to act as a manual back-up for Primary or Secondary Servers.  It's generally used as a method of manual Disaster Recovery, with Hot Standby deployed as a first line of defense, for automated Business Continuity.

AFAIK, any Genesys Server component can be deployed as Cold Standby - but it has to be licensed too!

There are, I am sure, documents available on this type of deployment - perhaps you should look a little harder?

I disagree.
Where in theory you can deploy as many as 'standalone' components as you want, there are other limitations that won't allow you to have a cold standby configuration (e.g. think about associating two different T-Server to a single switch). Off the top of my head, only those application types that *don't* support warm/hot standby can be deployed in a cold standby configuration.
Secondly, I believe there is no licensing involved for cold standby, neither commercially, nor technically.

Agree with Fra
The cold mode is the most basic one, no Genesys layer is involved

I am happy to be corrected... :)

Multiple TServers can be configured on certain types of Switches that have the capacity for more than 1 CTI Link.  The generic TServer config also allows for more than one set of "tcpip-link" settings, for multiple Switches, in different modes.

I will go away and do some homework, because my recollection of a Cold Standby was to allow for a Disaster Recovery site to be implemented and, if utilized, the components that need licences would need to be allocated.  On reflection, if it is Cold Standby, then the Primary (hot/warm) needs to have failed, for you to use it - and that would not incur extra licences.

I'm going to find some literature and amend my post... :)

Seems as thought I opened a can of worms, doing my homework....

So, not everything is available as Cold Standby - and not everything is available as Hot or Warm Standby.

Is there are definitive list of these items, anywhere - showing what modes they actually do support?  Would be very useful to know!

Thanks,

Hot/Warm is based on each product, described on each deployment guide.
About Cold, no reference as is more an OS/manual task rather than Genesys one.
