The instance ID is a name up to 64 characters long, that must be unique throughout the network irrespective of case. It is particularly important when authentication is used.
During installation, the name of the local 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 the FT administrator must change the local instance ID via operation parameter settings.
Partner instance IDs
You store the instance identifications of partner systems in the properties of the partner system. Consequently, the partner system must be entered in the partner list, see section “Partner list”. With the aid of the partner systems’ instance IDs, openFT manages the resources assigned to those partners, such as request hold queues and cryptographic keys.
