Managing hostname for SAP Disaster recovery scenario

[former_member246738]

Dear Experts,

We are in the process of setting up DR for SAP systems installed on SAP ASE. We have decided to Sybase Replication server to achieve DR for the database layer but we still have some open questions w.r.t application layer namely:

1. How can we install the application layer in a way (I guess virtual hostname) so that the end user does not need to adjust anything in their logon pad or browser after a takeover by the standby site? In our case, the SAP system on the primary site is installed on a cluster with ASCS and DB installed on the virtual host and PAS and AAS on each of two different hosts with the physical hostname.

2. How can we minimize the need for adjusting any RFCs or interfaces after a takevover by the standy site? CNAME/A-record?

The DR will be setup on Microsoft Azure.

Thanks and Regards

Joyee

Dear Goran,

Going through the document I realized that ASR is really useful if we have a 3 tier installation but this is not true for our case. The on-premise systems are 2-tier installations with ASCS and DB installed on the virtual host and 2 application servers installed on each of the 2 physical hosts. The installation is not distributed, i.e there is no separate DB server.

Thanks
