When SSH Tectia Client is used to rename or transfer files or mainframe datasets to/from z/OS hosts, and direct MVS dataset access on the server side is needed, you need to define the following environment variables on the client:
SSH_SFTP_STREAMING_MODE=ext
to activate extended streamingSSH_SFTP_CHECKSUM_MODE=no
to deactivate the checksum modeThe checksums cannot be used with streaming, because checksum calculation requires staging, but staging and streaming are mutually exclusive.
Use the extended streaming only in connections to z/OS hosts, as it can slow down the transfer of small files in other environments.
For information on the --streaming=ext
command-line option, see scpg3(1) and sftpg3(1).
For information on the --rename
command-line option, see sftpg3(1).
