Simplify FTP with z/OS Data Sets

To transfer a data set from one z/OS system to another via FTP, the target system needs to have compatible attributes set or else you encounter errors such as

EZA2590E send error from send_data - EDC5140I Broken pipe. (errno2=0x76697242)

EZA2603E Error sending the file

451-Error: Name=BSMRBF RC=-13

451-System completion code and reason: B37-04

451-Data set is out of space.

451-Error (1013) closing the data set.

451 Transfer aborted due to file error.

Those errors suggest several possibilities, including the need for more DASD. In our situation, though, we needed to use the FTP LOCSITE command to set attributes based on the source data set. For example:

LOCSITE TR PRI=13733 SEC=1500 REC=FB LRECL=4160 BLKSIZE=24960

This idea is to have the FTP command detect that the source is a z/OS data set and the target system is a z/OS system and then suggest a LOCSITE/SITE command (depending on whether a get/put was used) with attributes that might help the transfer succeed.

For example:

EZA2590E send error from send_data - EDC5140I Broken pipe. (errno2=0x76697242)

EZA2603E Error sending the file

451-Error: Name=BSMRBF RC=-13

451-System completion code and reason: B37-04

451-Data set is out of space.

451-Error (1013) closing the data set.

451-Possible to succeed with LOCSITE TR PRI=13733 SEC=1500 REC=FB LRECL=4160 BLKSIZE=24960

451 Transfer aborted due to file error.
