Dear Experts
I am Installing the SAP ECC6 EHP4 Clustering in the Windows 2003 Enterprise Edition. I have completed the windows Clustering MSCS and Database Clustering SQLSERVER 2005 in the NODE A and NODE B. I also aware that i need to install the Replication Server in NODE A and NODE B. My Doubt is whether ASCS in NODE B is Mandatory? and Dialog Instance is also Mandatory ?
