Eric is correct. Unfortunately this confusion may trace back to IBM's usage of Hot/Warm/Cold (HWC) for designating secondaries. It works for other IBM products except for Informix. So you know, we are working to clarify when a license is required and when it isn't in the licensing document. It will say something similar to this when it finally comes out: "For H/A clusters, as long as the secondary node is only functioning as a backup/failover secondary, it can be deployed without an additional IBM Informix license charge. However, if any H/A cluster secondary node is used for SQL or NoSQL operations (read, write or delete), the secondary node must be fully licensed. Shared Disk Secondary (SDS) environments always require a license using the same charge metric as the primary server. Backup operations performed on a secondary is not a licensable activity."

I hope that helps

Hello Carlton.

The customer has tried to get something official about this from IBM (in Denmark and Finland) but they always refer to this document that  "works for other IBM products except for Informix." 

They do not want this to be debated in the next software license compliance audit.

Can we consider your statement in this discussion thread as an "Official IBM Statement"? 
Do you have any timeframe for the updated licensing doc?

Best regards,
-Snorri
