FailOver or Hot site setup

I would like to set up a failover or hot site with hardware and software to host an Oracle 9 database run on a Windows 2003, an Oracle 8 database on a Sun Solaris 9 platform......Is it necessary to have the identical platform at the hot site? Can an Intel box running Linux be used to host both at the hot site?

If you get a more knowledgeable solution, pass me by; I haven't tried this.  My expert opinion, however, is that you have a decent shot at making this work.  So no, the identical platform is advisable but not necessary; and yes, Linux should be able to handle the instances.  The issue as I see it is to configure your init values to allow cross-platform path equivalents, i.e., C:/oracle/datafiles would map to /ora01/oradata/$ORACLE_SID.

These days, the professional providers like Iron Mountain might give you a virtual OS environment on a blade server.  You can look into database virtualization when you get up to 10g.
