Steps to Register Shell Script as a concurrent program

step 1:
Place the .prog script under the bin directory for your
applications top directory.

For example, call the script ERPS_DEMO.prog and place it under

step 2:
Make a symbolic link from your script to $FND_TOP/bin/fndcpesr
For example, if the script is called ERPS_DEMO.prog use this:

ln -s $FND_TOP/bin/fndcpesr ERPS_DEMO

This link should be named the same as your script without the
.prog extension.

Put the link for your script in the same directory where the
script is located.

step 3:
Register the concurrent program, using an execution method of
'Host'. Use the name of your script without the .prog extension
as the name of the executable.

For the example above:

step 4:
Your script will be passed at least 4 parameters, from $1 to $4.

$1 = orauser/pwd
$2 = userid(apps)
$3 = username,
$4 = request_id

Any other parameters you define will be passed in as $5 and higher.
Make sure your script returns an exit status also.
