Why is this in backticks?
Code:
`$ESAHOMEINSTALL/ESA/bin/reportEvent raise APP 1 .1.1.1.3 "Messaging Server Down"`

What is it, anyway? It may be the thing that's demanding a terminal, since I don't see much else that would.

There's some worryingly long pipe chains in there. You can reduce that in lots of ways.

1) You don't need wc -l to check if grep found anything. grep returns a code like any other program.

2) If you have grep | sed | grep | kitchen | sink, you can reduce that by putting them all in one awk call.

3) You're using functions in /bin/sh. /bin/sh is not guaranteed to have functions. Use ksh or bash if you really need functions.

4) You're not using functions in a way that really organizes your program anyway.

5) You're not using if/elif/else properly, nesting more if's inside instead of using elif.

Code:
if ps -ef | awk '/java/ && /[mM][sS]1@[iI][pP][xX][.][cC][oO][mM]/ { exit 0 } END { exit 1 }'
then
        echo "MS is down, please check"
        # What application is this?  Is it supposed to be interactive?
        $ESAHOMEINSTALL/ESA/bin/reportEvent raise APP 1 .1.1.1.3 "Messaging Server Down"
elif $ESAHOMEINSTALL/ESA/bin/printActiveAlarms | grep "Messaging Server Down" >/dev/null
then
	$ESAHOMEINSTALL/ESA/bin/reportEvent clear APP 1 .1.1.1.3 "Messaging Server Down"
else
        # Why?
        echo " "
fi


if ps -ef | awk '/java/ && /[nN][aA][mM][eE]=[tT][rR][aA][fF]_[sS][vV][rR]/ { exit 0 } END { exit 1 }'
then
        echo "TS is down.. Please check "

      $ESAHOMEINSTALL/ESA/bin/reportEvent raise APP 2 .1.1.1.3 "Traffic Server Down"

elif $ESAHOMEINSTALL/ESA/bin/printActiveAlarms | grep "Traffic Server Down" >/dev/null
then
        $ESAHOMEINSTALL/ESA/bin/reportEvent clear APP 2 .1.1.1.3 "Traffic Server Down"
else
        # why?
        echo " "
fi

endusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

	 /bin/bash		    /bin/csh
	 /bin/jsh		    /bin/ksh
	 /bin/ksh93		    /bin/pfcsh
	 /bin/pfksh		    /bin/pfsh
	 /bin/sh		    /bin/tcsh
	 /bin/zsh		    /sbin/jsh
	 /sbin/pfsh		    /sbin/sh
	 /usr/bin/bash		    /usr/bin/csh
	 /usr/bin/jsh		    /usr/bin/ksh
	 /usr/bin/ksh93 	    /usr/bin/pfcsh
	 /usr/bin/pfksh 	    /usr/bin/pfsh
	 /usr/bin/sh		    /usr/bin/tcsh
	 /usr/bin/zsh		    /usr/sfw/bin/zsh
	 /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.

NOTES

       Restricted shells should not be listed in /etc/shells.
