[INUG-Users] redundancy and availability on Netcool Omnibus v7.1

[Niket Mohey]

its called

"Event Service Framework (ESF) v1.3 Usage Guide""

 i think v1.3 is the latest version; you will have to request the same from
IBM. If you are a partner they should not have a problem distributing it to
you. I would say raise a PMR and request for the same. Alternatively you can
request it via your IBM account manager.

HTH.
