RPC Error : Can't encode arguments

devnux · 06-17-2008, 05:12 PM

Hi,
I am making a software in which I have to transfer files from a computer to another. I am using RPC to do this. I have problem with large files (not too large actually).
On my xdr I've declared the file content as an opaque type with variable length. I'v also tried with fixed length and for both I have encoding issues when the data transfered is too big (larger than 9000 octets).

Code:

struct import_args {
  opaque file<>;
};

Is there a limit for arguments length with RPC ? Is it configurable ?
Or do I have to call the RPC many times with each time a small part of the file till transfering all the file's data?

Thanks.

I think the existence of a limit depends on the implementation (at least according to RFC 1831). I would guess that if there were a limit it would be 8192 rather than 9000 bytes. If these are linux machines perhaps you can change the limit through sysctl.
