Hello Everyone,
The below script will help us to find number of processes runs in the background and send us alerts based on warning and critical thresholds.
Script :
# ]$ cat /home/oracle/DBA/bin/running_process.sh
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
#!/bin/bash # Syntax to run this script # ./running_process.sh oracle 100 170 # ./running_process.sh PROCESS_NAME WARNING CRITICAL export MAILIST='ajaykumar@ktexperts.com, process_name=$1 _limit1=$2 _limit2=$3 _proc=`ps -ef | grep $process_name | wc -l` if [ "$_proc" -ge "$_limit2" ] then echo "Current Running $process_name Proccess is running too high $_proc " > /tmp/proc.log cat /tmp/proc.log cat /tmp/proc.log | mailx -s "${TODAY} - Current Running $process_name Proccess is running too high/Critical $_proc " ${MAILIST} else if [ "$_proc" -ge "$_limit1" ] then echo "Current Running $process_name Proccess is running more than expected $_proc " > /tmp/proc.log cat /tmp/proc.log cat /tmp/proc.log | mailx -s "${TODAY} - Current Running $process_name Proccess is running more than expected $_proc " ${MAILIST} fi fi |
Script execution :
Syntax : ./running_process.sh <PROCESS_NAME> <WARNING> <CRITICAL>
Here I have executed by specifying java process with warning threshold 8 and critical 15

[oracle@oracl12 ~]$ sh -x /home/oracle/DBA/bin/running_process.sh java 8 15 + export MAILIST=ajaykumar@ktexperts.com + MAILIST=ajaykumar@ktexperts.com, + process_name=java + _limit1=8 + _limit2=15 ++ ps -ef ++ grep java ++ wc -l + _proc=10 + '[' 10 -ge 15 ']' + '[' 10 -ge 8 ']' + echo 'Current Running java Proccess is running more than expected 10 ' + cat /tmp/proc.log Current Running java Proccess is running more than expected 10 + cat /tmp/proc.log + mailx -s ' - Current Running java Proccess is running more than expected 10 ' ajaykumar.@ktexperts.com |
In above script output total 10 java processes are running and it sends us warning alerts. It will help us preventing DB crash.
