ISR Provisioning API Startup Commands

To verify ISR Provisioning API service status, use the following command:
```
#service provapi status 
```
In the case where you need to disable provapi service permanently, use the following command:
```
#sudo systemctl disable provapi
```
Then verify that the provapi service is disabled as follows:
```
#systemctl list-unit-files --type service provapi.service
```
Once you've disabled the provapi service this way, the service will not start up automatically after a FACE server reboot.
To enable and start the provapi service, use the following commands:
```
#sudo systemctl enable provapi
#service provapi restart
```

Note:

During application startup, tomcat attempts to connect to each database 3 times. If both databases are down, the application does not come up and it is in a failed state. The provapi service should be manually restarted once you have proper Database connectivity.

When the application is running, if either database goes down, the application attempts to connect to the other database. In a case where both databases are down, the application fails.
