You need to have multiple z114s with and associated zBX. I think you'd do failover just like you would with any other "racked mounted" servers. If the rack fails, all the servers fail. So you need the same techniques with a zBX "rack". I'm not a PC person, but I think this involves TCP connections between a server and it's failover twin. > How do I convert Solaris to zLInux under z/VM?

Yes, you must recompile. z/Linux runs on the z/Architecture instruction set. Solaris runs on Intel or SPARC(?). You can't run Intel or SPARC instructions on a z. However there are two exceptions that I can think of which __may__ not need recompilation. The first is Java code. The .jar and .class files should run on any compatible JVM, regardless of the underlying hardware architecture. Another possibility is .NET applications. They __might__ run on a z/Linux using Mono. Again, because they don't run "native", but on an instruction emulator. Shell scripts may need some changing. Perl, Python, Ruby and other intepreted language may need some changing, depending on the levels of the intepreter on z/Linux versus the one on Solaris. > > > -- > George Henke > (C) 845 401 5614 I wish we were doing something like this. But we're z/OS only and IT management would like to go MS-Windows only. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
