Special thanks to Buddy Lumpkin who send a piece of code to test with. if any body interesting in this code please contact Buddy at : [Buddy.Lumpkin@nordstrom.com] My original post is below. Summary: - Solaris 2.6 sure can handle files > 2 GB but applications may have to be compiled against the appropriate system/interface calls in order for it to work. - Try to use largefiles mount option to mount file system where large files reside and reuse the application. mount -o largfiles /dev/dsk/c0t0d0s0 /mnt - Solaris 2.6 _cannot_ use SWAP partitions > 2GB. You can have bigger ones, but it will only use 2GB of the partition. - Read more about largefiles at: <http://www.sun.com/software/solaris/2.6/faqs/faq-largefiles.html> http://www.sun.com/software/solaris/2.6/faqs/faq-largefiles.html man largefiles,man lfcompile,man interface64,man lfcompile64, man mount_ufs - The problem was seen before with Oracle, Quote Marc Alvidrez [ <mailto:cram@greenavenger.com> cram@greenavenger.com] : I had this problem with Oracle. I was exporting a db that was much larger than 2GB, and by default Oracle attempts to create a single file to hold the entire export. It could not do so; it kept failing at the 2GB mark. To make sure that largefile support was active, we successfully tried making files >2GB with dd. In the end we had to use a work-around suggested by Oracle. It was not the underlying OS that was to blame for the problem with 2GB files, it was Oracle. Unquote Marc Alvidrez Thanks again.

I can issue the command "mkfile 3g test.dat " successfully , On the other hand an application can not read/write files > 2GB. Can anyone of the Gurus out there please explain this ? Sorry if this question sounds primitive. Appreciate any input.
