We've tried approach 1 with two servers.

We registered two node names, Na and Nb, for the client and associated
one with schedule A of server A and the other with schedule B
of server B. Our two dsm.opt-files are in separate directories.
Each of the dsm.opt-files contains the nodename option.

Before starting schedule X we set the environment variable
DSM_LOG to the directory where the dsm.opt-file with nodename Nx is in
and the environment variable DSM_CONFIG
to the dsm.opt-file with nodename Nx.

It works.
