Global Events Demo

This project is designed for testing the CUBA Global Events add-on.

System Requirements

Linux or macOS
Locally installed PostgreSQL 9.5+
16GB RAM and a modern multi-core CPU
Free port ranges: 7770..7776, 7801, 7802, 8050..8056, 8080..8086, 8090..8096, 8780..8786

First, create local PostgreSQL database which will be used by all configurations below:

    ./gradlew createDb

Start Tomcat with core, web and portal blocks:
```
  ./gradlew setupTomcat deploy start
```
Open http://localhost:8080/app in two different browsers.
Open Application > Screen1 in both browsers. Click Send test event in one browser and see how the number of received events is increased in both.
Open app-core.glevtdemo:type=CoreTester JMX bean in one browser. Invoke sendUiNotificationEvent operation and see how the number of received events is increased in both browsers.
Invoke sendBeanNotificationEvent operation, then open Entity Inspector for the Event Registration entity and make sure there are three instances with Receiver fields indicating that the event was received by beans of all three blocks: core, web and portal.

Start cluster of six Tomcat servers and wait for all servers to load:
```
  ./gradlew setupClusterEnv startClusterEnv
```
In this setup, web3 and portal6 are connected to core1, web4 and web5 are connected to core2.
Open http://localhost:8083/app (web3), http://localhost:8084/app (web4), http://localhost:8085/app (web5) in different browsers and send UI events using the screen.
Open JMX console and select localhost:7771 or localhost:7772 JMX connections (core1 and core2 respectively). Send UI events and watch the number of received events in all browsers.
Invoke the sendBeanNotificationEvent JMX operation and ensure Event Registration contains a record with the Receiver field showing a bean from the portal block.
Stop cluster:
```
   ./gradlew stopClusterEnv
```

Open terminal in the project root and execute:

  ./run-system-test.sh /some_path/chromedriver
