Sybase replication server on HA / DR

Hi Experts,

We are in the process of setting up DR environment for Sybase ASE using replication server. The primary site has an HA configured.

My doubt is when we need to install replication server at standby site, what host needs to be specified as the "primary system hostname" - The hostname of CI or the DB server.

Additionally, do we need to install replication server on both nodes of HA cluster? and how would the DR agent configuration work in case of DB failover to the CI node?

Unfortunately, there is very little documentation available online on how to setup the DR environment, apart from SAP note 1891560

Would appreciate your invaluable inputs on this.

Thanks in anticipation.

Regards,

Varun
