The instance ID must be unique throughout the network irrespective of case.
Local instance identification
During installation, the name of the computer in the local network is defined by default as the instance ID.
If it cannot be guaranteed that this name is unique in the network then you must change the instance ID using the -id option of the ftmodo command. In the openFT Explorer, use the Administration menu, Operating Parameters command, General tab, Identification parameter.
Partner instance IDs
Instance IDs of partner systems should, from your local system’s point of view, correspond to the partner address, by which the partner system is known in the openFT. Instance IDs of partner systems should, from your local system’s perspective, correspond to the partner address by which the partner system is known to openFT. If this is not the case, you must enter the partner in the partner list and explicitly specify its instance ID.
Note the following:
If you do not specify the instance ID when entering the partner in the partner list, the partner address is set as the default with openFT and ADM partners (without port number and/or transport selector if these were specified with the partner address). This means that the instance ID of the partner must then match the specified partner address (without port number/T selector).
If your partner system is still a version of openFT equal to or older than V8.0, authentication is not supported. In this event, you should specify %.<processor>.<entity> (with the processor name and station name of the partner) as a dummy ID when entering the partner in the partner list, so that incoming requests from this partner can be assigned to this entry.
Alternatively, it is possible to resolve the name using a DNS or to make an entry in the hosts file (/etc/hosts on Unix systems) or in the TNS. When TNS is used the global name must correspond to the instance ID of the partner.
