how startSQLRepository connects to database

The startSQLRepository tool cannot access the datasource that is inside the Application server. So we layer the JTDataSource and make it point to FakeXADataSource which is a datasource setup at the Nucleus level.

When StartSQLRepository tool starts, it creates an instance of Nucleus in a separate JVM that it is starting from the command window and in that Nucleus will create the JTdataSource and the FakeXADataSource components to point to the appropriate schema which we are configuring.

Whenever the startSQLRepository tool is run without giving the –s server_name option, the last layer in the config path will be the home/localconfig. But if we pass on the server name, then the last layer will be the home/servers/server_name/localconfig.
