Well Jim, first of all, thank you for the fast and detailled reply.

I am going to use Oracle without OPS/RAC.

One further question: Am I correct that the second server is running but hasn't start the oracle-instance until ServiceGuard tells him to do that?

Can you give an example for that "package-thing"? Do you mean that I after I connected to an oracle-instance I always have to call the package within each statement? Can't believe that!
