Oracle R12 Installing Error Part-I

Oracle R12 Installing Error
Error:

$./rapidwiz

I found this error " Exception in thread "main" java.lang.UnsatisfiedLinkError:

/app03/StageR12/startCD/Disk1/rapidwiz/jre/Linux_x64/1.5.0/lib/i386/xawt/libmawt.so: libXext.so.6: cannot open shared object file: No such file or directory".

Workaround:

Run ldd libmawt.so
