Hi Andreas,
thanx a lot.But I didn't get it.If you are creating a cluster, does the cluster always need a special software for clustering? Or is Oracle without a special software able to create and handle a cluster? I think that is no possibility creating a cluster without soecial software like HACMP or Veritus....isn't it?
