How to extend 2 GB file size limitation

UNIX Solaris
1

Hello All,

I am using a SunOS machine. My application creates output files for the downstream systems. However output files are restricted to 2GB of file size in SunOS due to which I am forced to create multiple files which is not supported by the downstream due to some limitations.

Is there a way to over come the file size limitation from 2 GB to 3 GB or beyond that?

I would be thankful for suggesting me some solution to extend the file size limitation.

Thanks,
Raghu

which os version and what filesystem type do you use?

Ours is a SunOS 5.8 version and about filesystem I am not sure how to identify that,
can you please guide me in identifying the filesystem?

Regards..

How about setting the ulimit to unlimited ?

look at the output of "df -n".

I guess it's pcfs, aka FAT.
If not, it might be the application that isn't large file aware.

man largefile

for details.
