Uploading the user certificate to z/OS

After you download the certificate file to your workstation, you must upload it to your z/OS® system. There are many ways to transfer files from your workstation to your z/OS system. For example, you can upload the certificate file with Personal Communications 3270 or you can use TCP/IP FTP. The important things to remember are the certificate file must be uploaded to z/OS as binary data, the certificate file must be stored in a sequential data set, and the sequential data set must have RECFM=VB and LRECL=256 or greater.
