This is because the way that the large files are supported in Solaris 2.6 involves totally different system calls to the standard set... e.g.: open() is used for files under the 2G limit, and open64() for files that may be larger than 2G; ditto fstat() and fstat64(), lockf() and lockf64(), and so on. Parameters passed to those calls are also different. As a result, software like Oracle will have to be *extensively* rewritten to support large files, especially if they are also required to work under Solaris 2.5.1, which doesn't support the new calls.
