The shell script uses the exit status from pgrep and throws its result away. (Alternatively you could capture the result in a variable and then test it for having a value: pid=`pgrep ...`; if test -n "$pid")
The -u oracle and -x options make the match even more precise.
See man pgrep.
Hi,

I tried to loop in the logic for all db_sid that are currently running and modified logic as below..but program running but wrong results even though database and listners are up when i checked manually
existing oracle instance running
Code:
[oracle@ip-xx-xx-xx-xxx~]$ ps -ef|grep smon
oracle   15093     1  0 Nov08 ?        00:00:30 ora_smon_orcl
oracle   15486     1  0 Nov08 ?        00:00:30 ora_smon_orcltest

Now trying to get each instance that is running ..i.e only db_sid name by omitting ora_smon_ and getting only name

for ora_smon_orcl ==> orcl
for ora_smon_orcltest ==> orcltest
Code:
for db_sid in `ps -ef | grep smon | grep -v grep | awk '{ print $8 }' | cut -d '_' -f3` ; do
echo $db_sid

db_sid_pro="ora_smon_$db_sid"
echo $db_sid_pro
source /home/oracle/$db_sid
ora_home=$ORACLE_HOME
echo $ORACLE_HOME

case "$db_sid" in
"$db_sid_pro")
echo "hi"
tag="true"
echo $tag
msg="$db_sid database instance is running"
echo "$db_sid_pro database process is running"
;;
*)
if [ -e $ora_home/dbs/spfile$db_sid.ora ];then
msg="database is down"
echo "database is down"
tag="false"
else
tag="false"
msg="Incorrect database SID - $db_sid. Please provide the correct database SID"
echo "Incorrect database SID - $db_sid. Please provide the correct database SID"
fi
;;
esac

the output shown on terminal is below: but manually i checked databse is up and listener also up..May be i am missing something in programming logic here not really database issue


Code:
orcl
ora_smon_orcl
/dbusr/app/oracle/product/12102
database is down
Oracle listener is down please make it up
database is down
Oracle listener is down please make it up
orcltest
ora_smon_orcltest
/dbusr/app/oracle/product/12102
database is down
Oracle listener is down please make it up
database is down
Oracle listener is down please make it up

However I find below is causing trouble..because when I put some debug echo its not displaying "hi"

Code:
case "$db_sid" in
"$db_sid_pro")
echo "hi"
tag="true"
echo $tag

and also i have manually checked for below line.. files are indeed exist as per below conditon

Code:
if [ -e $ora_home/dbs/spfile$db_sid.ora ];then

Any suggestion
