Hi All
Thanks for your help in this issue. I just wanted to let you know that I've fixed the problem in the following way:
After installing the AS Java instance on the first node, and the SAPDB software on the other three nodes of the cluster, I was able to restart the Instance after copying the files Databases.ini and Installations.ini in /sapdb/data/config from the original cluster node, out to the other nodes. It was just a question of synching the config info around the cluster, as I suspected.
Thanks again for your help. Much appreciated.
