HA_Switch

This sample demonstrates how to switch between master and replica eXtremeDB High Availability applications.

How to Run

See instructions here on how to build this and other samples on your development platform. Once built, the sample can be run from the \target\bin directory.

In a console window run:

 
    haswitch
     

The application attempts to connect to an existing master database. If the attempt fails, it switches to master mode, creates and populates the database, then enters a loop creating and deleting objects.

Then in a second console window run:

 
    haswitch
 

This instance connects to the first application instance. To exchange master and replica roles, press <Enter> in the first or second console window. To stop the application, type "q <Enter>".

But it is more instructive to run one instance in your development environment debugger, stepping through the code.
