The server received an RETR command to retrieve a fixed format tape data set when the server was configured with TAPEREADSTREAM=TRUE and TRAILINGBLANKS=TRUE.
The RETR command is rejected.
If your client is a z/OS® Communications Server FTP client, issue a SITE NOTAPEREADSTREAM or SITE NOTRAILINGBLANKS subcommand to change the value for the current session. If your client is not a z/OS Communications Server FTP client, issue a QUOTE SITE NOTAPEREADSTREAM or QUOTE SITE NOTRAILINGBLANKS subcommand to change the value for the current session. Fore more information about the SIte subcommand, see z/OS Communications Server: IP User's Guide and Commands.
To change the TAPEREADSTREAM or NOTRAILINGBLANKS value permanently, change the TAPEREADSTREAM or TRAILINGBLANKS statement in FTP.DATA. For more information about the TAPEREADSTREAM or TRAILINGBLANKS statement, see z/OS Communications Server: IP Configuration Reference.
