One way that could work would be using virtualization, perhaps installing the Oracle solution on the host servers (SPARC) to have virtual machines running on x64.
It would be necessary to confirm with Oracle or a provider for Solaris + SPARC to get a best working solution.
We have long evaluated the possibility of making a version for SPARC, however, the dependencies and libraries that we need to achieve have too many limitations and complications.
