Well,

To answer Q2:

Given the fact that the sparc chips run very slow (Slowaris) and that the IBM chips run fast, the following will happen to your system. The DB server (IBM processors), will be idle a lot. The Application Server machin (SUN Sparc) will have a high utilization and bottleneck the whole system. This is a rule of thumb assuming that most of the work is done in the Application and less work is done on the DB server.

Anjo.
