IS-U one or two instance

[Former Member]

Hello

The electricity industry body requires the access between supplier (retail) side of the business kept separate from the network (metering) side of the business. The current debate is to either implement one instance of IS-U or to have 2 instances of IS-U to meet this requirement. Has anyone had any experience in implementing one instance of IS-U to manage both the supplier and network side of the business?

Could you please share with me the pros and cons of having 1 instance vs. 2 instances of IS-U?

Thank you

Hello

Thanks for your reply. How about the initial cost (2 config, 2 hardware etc) and the on-going costs of having 2 instances instead of 1 IS-U. Did your company compare costs?

Do you think having 2 instances gives to double the benefits to justify 2 instance instead of 1?

How do you manage keeping both instances synchronised at all times.

How about the applications/modules that talks to both instance of IS-U. How would this be separated? For example, if you have CRM or BW interfacing to both instance of IS-U, would this cause the same problem as having one instance?

Thank you

Hi,

if you use a 1-client solution (aka 2-contract model) you should take into account the following:

- this solution is possible only with the releases 4.64/IDEX (german addon for IS-U) and >= ERP 2005

- you have a more complex customizing and more complex data model.

Many german utilities use the 2-contract model, if they are supplier and distributor. For customers which have another supplier they use the IDE-functionality.

Best regards,

Alexander
