The srvctl export gns command exports Grid Naming Service (GNS) instance data to a file that you can use when you are either moving GNS from one server cluster to another or when you are creating a client cluster
SRVCTL extracts the data from OCR. Exported data includes:
The credentials used to authorize users, which includes the VIP address on which the server listens
The names and DNS records kept in GNS
Note:
This command is only available with Oracle Clusterware.
Use the srvctl export gns command with the following syntax:
srvctl export gns {-instance path_to_file | -clientdata path_to_file}
