Write system error

Post by marko_kruz »

Hi,

We are testing cozsftp in batch mode. Getting a file from the UNIX server we get the following error:

I don't know why 5552865279 bytes are recieved when the real file size is 2038518423 bytes. Running the same JCL but using a smaller file to get, it completes OK, and in this case the file size match. It doesn't seem to be a space problem because there is enough disk space.

I found the problem, the undefined (U) record format used is not efficient to allocate the dataset. So, I changed the record format by Variable Blocks (VB). The problem was solved.

Thanks anyway.

I'm glad you solved it.
You are correct - you were running out of space probably because there was no DCB specified on the DOWNLOAD DD.
