Problem to archive large files (> 2Gb) from Z/OS to Centera

Hello,

(First, please excuse me for my poor english, I'll try to be as clear as possible!)

We actually use SDK 3.2 on our Z/OS server.

I wrote a C store program to archive files from the Z/OS to the Centera using this SDK, and it works fine as long as the file to archive doesn't exceed 2Gb.

When I try to archive a larger file, I can see many I/Os operations for several minutes from the Z/OS to the Centera, the status returned from API functions of the SDK is 0, but the size of the file finally archived is 0 ! ! ! !

The Cclip has been created, nothing seems to be wrong, except that the file is not stored on the Centera.

Please, note that my store program also runs under UNIX, and that I have no problem to store large files from UNIX to Centera with this program.

Can somebody help me with my Z/OS problem?

Thanks
