Manage the platform

With Bonita Engine API, you can create and initialize the platform, start and stop the Bonita Engine.

Log on the platform

Before you can create the platform, you need to log in and get the platformAPI:

// Get platform login API using the PlatformAPIAccessor
PlatformLoginAPI platformLoginAPI = PlatformAPIAccessor.getPlatformLoginAPI();

// Log on the platform
PlatformSession platformSession = platformLoginAPI.login("platformAdmin", "platform");

// Get the platform API
PlatformAPI platformAPI = PlatformAPIAccessor.getPlatformAPI(platformSession);

Create the platform

This will create the database structure and put the platform state into persistent storage.
```
// Create the platform
platformAPI.createPlatform();
```
Initialize the platform

This will create the default tenant and initialize Bonita Engine environment. After this step, the technical user will be able to connect to the engine and create new users or import the organization.
```
// Initialize the platform
platformAPI.initializePlatform();
```
No business users are created by default and the default username/password for the technical user to connect to Bonita Engine can be retrieved in the file setup/platform_conf/current/tenants/[tenant_id]/tenant_engine/bonita-tenant-community-custom.properties using the platform setup tool ([tenant_id] being the default tenant ID, that is to say 1 when using the default configuration on a fresh installation).

Once you retrieved the default configuration using the platform setup tool, you can change this username/password by editing the file bonita-tenant-community-custom.properties and use the tool again to push the configuration to database.
Start Bonita engine

Starting the engine on a node starts the Scheduler service and restarts elements that were not finished by the Work service on the previous shutdown. Bonita Engine environment is marked as activated.
```
// Start the execution engine
platformAPI.startNode();
```
Stop Bonita engine

Stopping the node stops the Scheduler service. Bonita Engine environment is marked as deactivated.
```
// Stop the execution engine
platformAPI.stopNode();
```
