Database Switching Methods

Switching from one DataSource to another is a two-step process:

  1. Prepare the next DataSource, using the SwitchingDataSource.prepareNextDataSource(String pName) method. Pass this method the short name of the DataSource you want to switch to. This sets the nextDataSource property.

  2. Execute the switch, using the SwitchingDataSource.performSwitch() method.

The prepareNextDataSource and performSwitch methods send a SwitchingDataSourceEvent to each listener specified by the SwitchingDataSourceEventListener property of the SwitchingDataSource. This event can be of type PREPARE or SWITCH.

When you invoke the SwitchingDataSource.performSwitch() method, the SwitchingDataSource switches the value of the currentDataSource property to the DataSource specified by the nextDataSource property.
