Hi,
I Encountered the issue during installation of replication server on windows cluster node.
My environment is
Primary SAP HA on windows cluster and
Standby SAP Standalone on standby side.
i got the error
Assertion failed: Replication Server and Database server on same host is not supported in OS cluster environment
So my solution was install replication services alone with DR agent on saprate HOST, out side the cluster on primary side and install replication service on same host at standby side.
Working Solution is
Primary
SAP HA on windows cluster
NEW HOST/SERVER with Sybase replication server
Standby SAP Standalone on standby side + Sybase replication on same host.
And it work for me successfully, I asked SAP support to validate this solution but i didn't get any acknowledgement yet, But its working for me since 4 months.
