UNIX sftp from mainframe
I have the following UNIX script which copies a file from a UNIX server in Canada to a UNIX server in the UK.
LOG=/data/proj/sftp/canada.log
DAT=`date "+%d/%m/%y %H:%M"`
HOMEDIR=/data/proj/sftp
TGTFILE=P_DATA.csv
cd $HOMEDIR
echo "\nStarting retrieval of Canadian Data at $DAT" >> $LOG
# move old copy of file
if [ -f $TGTFILE ]
then
mv $TGTFILE $TGTFILE.prev
echo "Existing $TGTFILE renamed with .prev suffix" >> $LOG
fi
# get new file using sftp
echo "Using sftp to connect to
ftppora1@sxmq1014.pftg.ca" >> $LOG
sftp -b $HOMEDIR/ftpcmd -oPort=32
ftppora1@sxmq1014.pftg.ca 2>>$LOG 1>>$LOG
# check file retrived successfully
if [ -f $TGTFILE ]
then
echo "$TGTFILE retrieved successfully" >> $LOG
else
echo "*** Error retriving data ***" >> $LOG
exit 1
fi
exit 0
At present, I can run this script by logging onto the server as user xxxxx with password zzzzzz.
I want to automate this process - and wish to kick off the above script from JCL on the mainframe. I've been advised that an OPC job using TWS can be used, as this enables a remote ID and password to be specified on the appropriate job step. Anyone have any example JCL to do this?

sftp-server
SFTP-SERVER(8) BSD System Manager's Manual SFTP-SERVER(8)
NAME
sftp-server -- SFTP server subsystem
SYNOPSIS
sftp-server [-ehR] [-f log_facility] [-l log_level] [-u umask]
DESCRIPTION
sftp-server is a program that speaks the server side of SFTP protocol to stdout and expects client requests from stdin. sftp-server is not
intended to be called directly, but from sshd(8) using the Subsystem option.
Command-line flags to sftp-server should be specified in the Subsystem declaration. See sshd_config(5) for more information.
Valid options are:
-e Causes sftp-server to print logging information to stderr instead of syslog for debugging.
-f log_facility
Specifies the facility code that is used when logging messages from sftp-server. The possible values are: DAEMON, USER, AUTH,
LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH.
-h Displays sftp-server usage information.
-l log_level
Specifies which messages will be logged by sftp-server. The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that sftp-server performs on behalf of the client. DEBUG and DEBUG1 are
equivalent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR.
-R Places this instance of sftp-server into a read-only mode. Attempts to open files for writing, as well as other operations that
change the state of the filesystem, will be denied.
-u umask
Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask.
For logging to work, sftp-server must be able to access /dev/log. Use of sftp-server in a chroot configuration therefore requires that
syslogd(8) establish a logging socket inside the chroot directory.
