Sample scripts to start, stop, and monitor a generic application


Sample scripts to start, stop, and monitor a generic application
Prev	Appendix B. Sample scripts for generic application	Next

You can write your own scripts for the VCS Application agent to bring a generic application online, take the application offline, and monitor the status of the application.

You can also modify the following sample scripts and use them to start, stop, and monitor the application.

Sample script to start a generic application:
```
#!/bin/sh 
touch /tmp/sampleapp          # add any steps, if required
exit 0
```
You can modify the sample start script to suit the application requirements. If you save the start script with the name startsampleapp, then to bring the application online, the agent function runs the following command:

su - user -c startsampleapp
Sample script to stop a generic application:
```
#!/bin/sh 
rm -f /tmp/sampleapp          # add any steps, if required 
exit 0
```
You can modify the sample stop script to suit the application requirements. If you save the stop script with the name stopsampleapp, then to bring down the application, the agent function runs the following command:

su - user -c stopsampleapp

Note:

The value of the return code for the start and stop scripts must be 0. No other return codes are supported.

Sample script to monitor a generic application:
```
#!/bin/sh
APPLICATION_IS_ONLINE=110
APPLICATION_IS_OFFLINE=100
if [ -f /tmp/sampleapp ] ; then        # add any steps, if required
exit $APPLICATION_IS_ONLINE
else
exit $APPLICATION_IS_OFFLINE
fi
```
If you save the monitor script with the name monitorsampleapp, then to monitor the application, the agent function runs the following command:

su - user -c monitorsampleapp
