steps to bounce apache in r12

Automate Apache server restart (bounce) through script.

In this post we will know how to automate Apache server restart through shell script.

If  you are thinking to automating Apache server restart which can be done through a crontab entry.

Pls check carefully below steps:-

Here is Details :

Create the below entry in crontab (Please modify the timing in the cronjob as per your Apache restart requirement):

10 8  * * * su -c applmgr "sh /oracle/prodappl/11.5.0/bin/ApacheBounce.sh"

Note:  ApacheBounce is the script to be created which will do the Apache restart. Mineserver is the servername where Apache services are running. 

This example is for the services running on a single node and same concept can be followed while implementing on multiple servers.

Location of the bounce script:  /oracle/prodappl/11.5.0/bin/ApacheBounce.sh

The below mentioned are the contents of the Apache restart script (ApacheBounce.sh) :

#################################################################################

#Source the ENV file

. /oracle/prodappl/APPSPROD_XXX.env           

Sleep 5

# Notify all users before the restart.

cat $MINE_TOP/bin/ Apachedown.txt |  mailx -s "PRODUCTION  - Apache Bounce will happen  in 3 mins " -c “oracledba@gmail.com”

sleep 180

#Stops the Apache services

sh $ADMIN_SCRIPTS_HOME/adapcctl.sh stop     

sleep 10

# Kill leftover Apache processes

kill_processes=`ps -ef | grep "/iAS/Apache/Apache/bin/" | awk '{print $2}'`

echo $kill_processes

kill -9 $kill_processes

sleep 5

sh $ADMIN_SCRIPTS_HOME/adapcctl.sh start     # starts the Apache services

sleep 5

# Notify all users after restart

cat $CUST_TOP/bin/Apacheup.txt | mailx -s "PRODUCTION  Apache Bounce Complete" -c “oracledba@gmail.com”
