Batch script to monitor ORDS service and send mail notification it goes down

 

Hi Everyone,

 

Recently I came across an issue where ords service on windows was getting stopped due to some reason. It was hard to monitor as they had no mechanism to monitor this.

 

To mitigate the problem, I wrote a batch script which will monitor ords service’s uptime on windows . The script will send a mail once notifying service has gone down.

 

Save the following script in .bat format and schedule it as per your requirement in task scheduler.

 

@echo off setlocal enabledelayedexpansion set my_date=%date% set my_time=%TIME% set my_hours=%my_time:~0,2% set my_minutes=%my_time:~3,2% set my_seconds=%my_time:~6,2%   REM Define variables set APEX_URL=http://server1.example.com:7799/ords set MAIL_RECIPIENT='soumya.das@testmail.com' set SMTP_SERVER=smtp.office365.com set SMTP_PORT=587 set MAIL_SENDER=notification@example.com set MAIL_SUBJECT="Oracle APEX URL Status" set SMTP_USER=emr-notification@example.com set SMTP_PASSWORD=xyz123# set SUBJECT="Apex down Alert" set HOSTNAME=%COMPUTERNAME%   REM Check if the URL is accessible curl -s -o NUL -w "%%{http_code}" %APEX_URL% > D:\response.txt   REM Check if D:\response.txt exists if not exist D:\response.txt (     REM If D:\response.txt is not present, send email notification                powershell.exe -command "Send-MailMessage -From '%MAIL_SENDER%' -To %MAIL_RECIPIENT% -Subject '%SUBJECT%' -Body 'Oracle APEX URL is not accessible at %HOSTNAME% .Apex Service is down.' -SmtpServer '%SMTP_SERVER%' -Port %SMTP_PORT% -UseSsl -Credential (New-Object PSCredential('%SMTP_USER%', (ConvertTo-SecureString '%SMTP_PASSWORD%' -AsPlainText -Force)))" )   REM Read the HTTP status code set /p HTTP_STATUS=<D:\response.txt   REM Check if HTTP status code is 000, indicating a failure if "%HTTP_STATUS%" equ "503" (     powershell.exe -command "Send-MailMessage -From '%MAIL_SENDER%' -To %MAIL_RECIPIENT% -Subject '%SUBJECT%' -Body 'Oracle APEX URL is not accessible at %HOSTNAME%.Apex Service is down.' -SmtpServer '%SMTP_SERVER%' -Port %SMTP_PORT% -UseSsl -Credential (New-Object PSCredential('%SMTP_USER%', (ConvertTo-SecureString '%SMTP_PASSWORD%' -AsPlainText -Force)))" ) else if "%HTTP_STATUS%" equ "000" (               powershell.exe -command "Send-MailMessage -From '%MAIL_SENDER%' -To %MAIL_RECIPIENT% -Subject '%SUBJECT%' -Body 'Oracle APEX URL is not accessible at %HOSTNAME%.Apex Service is down.' -SmtpServer '%SMTP_SERVER%' -Port %SMTP_PORT% -UseSsl -Credential (New-Object PSCredential('%SMTP_USER%', (ConvertTo-SecureString '%SMTP_PASSWORD%' -AsPlainText -Force)))" )   REM Cleanup temporary files del D:\response.txt   endlocal
