Whenever the ChangeMan ZMF installer is executed, it will build a set of batch commands that will execute the FTP transmission of the files to the mainframe environment. For a variety of reasons some customers are unable to run either the installer or the generated batch script FTP commands. This can raise questions related to the dataset attributes that are required when uploading the new files to the mainframe.

The vast majority of uploaded datasets will be in TSO XMIT-format, hence require transmission to DSORG=PS, RECFM=FB, LRECL=80, BLKSIZE=3200 (or any appropriate multiple of 80) datasets. However, some, such as the *.WAR files, need to be uploaded to DSORG=PS, RECFM=U, LRECL=0, BLKSIZE=3060 datasets.

Reviewing the FTP commands generated in the FTP.input file can help here. Each set of transmitted files are preceded by the relevant commands and literals that define the transmission type (i.e. binary or ascii) and the target dataset attributes.
