This is untested, but should do what I think you're asking for:
Code:
#!/bin/ksh

SERVER=$(hostname)
MAILTO=abc@company.com
DATE=$(date)
ps -ef | grep '[j]ava' | mailx -s "JVM status before start" $MAILTO


if ! /was/abc/bin/startManager.sh > /tmp/start.log
then    mailx -s "ALERT: dmgr started $SERVER at $DATE" $MAILTO < /tmp/start.log
        exit 1
fi
sleep 30

if ! /was/abc/bin/startnode.sh > /tmp/start.log
then    mailx -s "ALERT: node started $SERVER at $DATE" $MAILTO < /tmp/start.log
        exit 2
fi
sleep 30

if ! /was/abc/bin/startServer.sh > /tmp/start.log
then    mailx -s "ALERT: server started $SERVER at $DATE" $MAILTO < /tmp/start.log
        exit 3
fi
ps -ef | grep "[j]ava" | mailx -s " node1 got started" $MAILTO

######### node 2 #############
date >> /tmp/b4strtnd2.log

ssh noide2 exec /tmp/script/mystrtscpt.sh

exit

Did you really intend ssh noide2, or should it have been ssh node2?

Note that this will only work correctly if /was/abc/bin/startManager.sh, /was/abc/bin/startnode.sh, and /was/abc/bin/startServer.sh all return exit status 0 if they complete successfully and return a non-zero exit status if they fail. Assuming that is true this script will return exit status 1, 2, or 3, respectively if one of those scripts fails; otherwise it will return with the exit status from /tmp/script/mystrtscpt.sh on noide2.

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
