Shell Script for Checking whether SAP is Up or not

Wonder how would you check whether the SAP is up or not from Unix Shell Script. Here is a small shell script which uses the Enviornment variables and some files to check whether the SAP is runnig or not from the Operating System.

It can be automated and the output message can be used for sending as an Alert. It could be modified to suit any Landscape. In this case the command for running the script is "$/usr/bin/checksap.sh SID"

# UNIX Shell Script for Checking
# 1. Whether SAP Has Started or not
# is found by checking whether kill.sap file exists or not
# and if it exists, whether the PID recorded in the file is live or not
# 2. Whether DB has started or notA
# is found using the Command R3trans -d
# 3. Whether SAP is able to detect the Message Server or not
# (important for Applicateion Server Test
