Explanation

https://docs.oracle.com/database/121/GSMUG/globser.htm#GSMUG649 This connect string contains three global service managers (sales-east1, sales-east2, and sales- east3) in the client's local region (east), and three global service managers (sales-west1, sales- west2, and sales-west3) in the client's buddy region (west). Client-side load balancing is enabled across the global service managers within each region by setting the LOAD_BALANCE parameter to ON in the address list for each region. Connect-time failover between regions is enabled by setting the FAILOVER parameter to ON. It is a best practice to have three global service managers in each region, for each region to have a buddy region, and for client-side load balancing and connect-time failover to be configured as shown in the example connect string. The REGION parameter is optional if only global service managers from the local region are specified in the connect string. This is the case when there is only one region in the GDS configuration, or could be the case when there are multiple regions, but it is not feasible to change the connect string of an existing client designed to work with a single database. If the REGION parameter is not specified, the client's region is assumed to be the region of the global service manager used to connect to the global service.
