hadr_remote_inst - HADR instance name of the remote server configuration parameter
This parameter specifies the instance name of the remote
server. High availability disaster recovery (HADR) also checks whether
a remote database requesting a connection belongs to the declared
remote instance.
1 Changes to this parameter take effect on database activation.
If the database is already online, you can have changes take effect
by stopping and restarting HADR on the primary database.
