Script To Monitor Concurrent Managers

Pre-requisites to Run the script:

Make sure mailx and sendmail is installed on your OS, also check below environements/file is created prior to execute the scripts.

This script is tested on Linux Server.

This script needs to be deployed in database node/server.

#Base location for the DBA scripts
DBA_SCRIPTS_HOME=$HOME/DBA_MON

#OS User profile where database environment file is set
$HOME/.bash_profile

Create Custom .sysenv file for scripts

Download(.sysenv)

Download .sysenv file and save it under $HOME/DBA_MON
$ chmod 777 .sysenv

$ cat $HOME/DBA_MON/.sysenv

export DBA_SCRIPTS_HOME=$HOME/DBA_MON
export PATH=${PATH}:$DBA_SCRIPTS_HOME
export DBA_EMAIL_LIST=kiran.jadhav@domain.com,jadhav.kiran@domain.com
#Below parameter is used in script, whenever there is planned downtime you can set it to Y so there will be no false alert.
export DOWNTIME_MODE=N

Script to check Concurrent Manager status and to send alert notification if one or more concurrent managers are down. 



Download(CMStatusCheck.sh)

Download CMStatusCheck.sh and save it under $HOME/DBA_MON/bin/
$ chmod 755 CMStatusCheck.sh

Logs and Out files will be generated under $DBA_SCRIPTS_HOME/logs/$HOST_NAME
So make sure to create logs/$HOST_NAME directory under $DBA_SCRIPTS_HOME before executing the script.

Once the script is ready, then as per the requirement please schedule it in crontab/OEM.

Execute the Script as below:

Syntax :  sh <script_name> <ORACLE_SID>

$ cd $HOME/DBA_MON/bin
$ sh CMStatusCheck.sh ORCL

This script will send the notification with details if one or more concurrent managers are down.
