TT-17013
The default hostname cannot be set to host_name because a local host of host_name is currently in use.
Additional Information
Using the built-in procedure ttHostNameSet you have specified a host name for a replication subscribe to a value that differs from the default host name already in use by a replication scheme. The host name is not changed. To view the current host name specified in the scheme, use the procedure ttHostNameGet.
