Each object store in your site requires its own JDBC data sources. You can configure the data sources by using the Configuration Manager graphical user interface or the command line.
You created the JDBC data source for the Global Configuration Data (GCD) earlier in the configuration process. You must add the data sources now for at least one object store that you want to upgrade. You can create additional object store data sources as needed either immediately after you create the initial object store data sources or after you have confirmed your Content Engine configuration.
