Connecting to Catalog Databases When No Global Service Managers Are Running

Maintain access to the GDS catalog database for administration when all Global Service Managers are down.

In the event that all Global Service Managers (GSM) go down, and you need access for a database administration or maintenance activity on the catalog database, you can connect directly by using the catalog database's local listener (or Oracle RAC SCAN listener). To do this, use a client connect descriptor/tnsnames entry that includes local listener addresses as the final failover option. This method bypasses GSM and allows DB maintenance even if no GSM processes are running.
