This may be because you are using single quotes in the here document. Try double quotes.

What do you see it doing if you add a set -x on the second line? The trace should show the commands being executed and some of the values being used.

I also noticed the command substitution around the message declaration (message=$(...)), but it's SH and the OS isn't mentioned, so I don't know if that's significant.

It is significant.

The subshell call message=$("this is my message $var whatever $othervar") will fail with command not found error.

There is also an issue with subshell call, which will not work in such form in legacy shells, so `command` is to be used in those.
Subshell expects a valid command not $("arbitrary text") or `"arbitrary text"`

For instance :
$ cat mess.sh 
message=$("This is my $(date +%s)")
echo $message
./mess.sh: line 1: This is my 1515156364: command not found

Try :
message="Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)"
echo "$message"
.. further code processing / inserting $message
cat <<EOF

Notice that no subshells are required and your program should produce results.

Have you considered writing an sql file and passing message as a parameter ?

Something in the lines of :
sqlplus user/passs @insertscript.sql "$message"
# where in your insertscript.sql you have :
INSERT INTO ALERT_EMAIL(PUID, ID, TxnID, Recipients,Subject,Body,IsNew,CreationDate,LastModifiedBy,IsSMS)
VALUES(ALERT_EMAIL_PUID_SEQ.NEXTVAL, '111111','','','&1,'body',1, SYSDATE, 'axienta',1);

Hope that clears things out
