Calling an expect script from another script (sh)

Question

How to call the EXPECT utility from SHELL script?
Our objective is - We have developed a shell script to connect the oracle database and generate the XML file and this XML file needs to be transfer to another windows machine using the SFTP servcies. We are planning to schedule this job using the CRONTAB.
Our first script 1:
# connecting to oracle database and generating the file
ORACLE_SID=TEST
ORACLE_HOME=/u01/oratest/db/tech_st/11.1.0
export ORACLE_SID ORACLE_HOME
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$ORACLE_HOME/bin:$PATH
output=`sqlplus -s /nolog <<EOT
set pages 0 feed off
whenever sqlerror exit failure;
connect xgbzprod/xgbzprod
exec XGBZ_GL_COA_XMLTAG_PROC;
EOT
`
cd /u01/oratest/gebiz_processed
for fn in GEBIZ_COA_RPO000*.*; do
# using the EXPECT utility to transfer the generated file to antoher machine
set timeout 10
spawn $env(SHELL)
match_max 100000
send -- "sftp username@IP Address\r"
expect -exact "[email protected]'s password:"
send -- "Password\r"
expect -exact "sftp>"
send -- "cd /<SFTP location>\r"
expect -exact "sftp>"
send -- "lcd /<Local locatoin>\r"
expect -exact "sftp>"
send -- "bin\r"
send -- "put $fn\r"
expect -exact "sftp>"
send -- "quit\r"
send -- "exit\r"
expect eof
-- When we run the above script it failes and the script is not recognizing the other variables.
-- We have split the procedure to keep the oracle connection in one script and another script for EXPECT utility. But we are lack of how to call the EXPECT utility in shell script.
Please help us

You might want to try to better understand shell script programming. It makes it otherwise difficult for a poster to recommend you a solution. I don't believe you can expect others to do all the development and testing work for you. Since this is a forum on a volunteer basis, you might also want to consider marking helpful replies and review received answers more carefully.
Perhaps the following will work for you:
#!/bin/bash
export ORACLE_SID=TEST
export ORACLE_HOME=/u01/oratest/db/tech_st/11.1.0
export ORACLE_SID ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
echo
output=`sqlplus -s /nolog <<EOT
   set pages 0 feed off
   whenever sqlerror exit failure;
   connect xgbzprod/xgbzprod
   exec XGBZ_GL_COA_XMLTAG_PROC;
EOT
`
echo "$output"
username="oratest"
hostname="11.10.11.159"
password="welcome1"
for fn in GEBIZ_COA_RPO000*.*; do
   echo "GL Chart of Accounts File Name : " $fn
/sftp.exp "$username" "$hostname" "$password" "$fn"
done
#!/usr/bin/expect -f
set username [lindex $argv 0]
set hostname [lindex $argv 1]
set password [lindex $argv 2]
set fn [lindex $argv 3]
spawn sftp $username@$hostname
expect -exact "[email protected]'s password:"
send -- "$password\r"
expect -exact "sftp>"
send -- "cd /sftp0002/uat/inbox\r"
expect -exact "sftp>"
send -- "lcd /u01/oratest/processed\r"
expect -exact "sftp>"
send -- "put $fn\r"
expect -exact "sftp>"
send -- "quit\r"
send -- "exit\r"
expect eofP.S. The above code is very simplistic and does not take error handling into account.
Using CURL, like I suggested in my first reply was an easier solution, since you don't need to to script Expect, but it turns out that you might need Enterprise Linux 6 or install at least CURL verison 7.19 to support sftp.
