How to change (NT)Domain Name after installed ERP?

[Former Member]

Hello,

We are planning to change (NT) Domain Name on environment of already installed ERP/BW(WAS 6.40)/SRM/SolMan(NW 7.0).

We know SAP recommend that customer should be Re-install or System-copy SAP-System if the Domain name is changed after installed systems.

However, we do not have enough time and budget for doing that.

Questions:

1). If the (NT) Domain name will be changed, we only need to change the

OS users of service for SAP-System?

(I think that it is needed to change only OS-users of SAP-service. Is there other setting for that?)

2). The method of only changing users of SAP-service is not supported in this case?

(The customer will be not taken the SAP-Official support after doing that?)

Thanks very helpful advice.

I'll explain that risk of the after supporting and proceed system-copy to the customer.

Dear

Changing domain name is not supported by SAP if done in a productive environment (after systems have gone live).

You will probably not get support by SAP after you change the domain name once system is live.

There are a bunch of changes you will need to perform as well.

The domain name is probably existing in the RFC's and you cannot change all of those through SM59.

You will need to update those entries at Oracle level.

SAP parameters containing domain name

Java environment where domain name is contained

Reset hostname buffer

Service marketplace

SAP Logon

STMS

Monitoring perhaps, non SAP job scheduling

Please reward points accordingly

Hello Tom-san,

Thank you for your important information.

I have not known that the RFC has included Domain name.

That will be a problem if we could not take a support from SAP by changing it manually.

So, I think that we should recommend that System-copy or re-install to the customer.

You need to proceed with an Homogeneous system copy in order to avoid issues...

Thats my recommendation

Hello

Field rfcoptions (table rfcdes) can have the domain name in it, for example an RFC that has a SAP gateway defined in it.

Kind regards
