An instance ID may have a maximum length of 64 characters and may be comprised of alphanumeric characters and the special characters. You are advised only to use the special characters “.”, “-”, “:” or “%”. The first character must be alphanumeric or the special character “%”. The “%” character may only be used as a first character. An alphanumeric character must follow a “.” character.
In order to ensure the network-wide uniqueness of instance IDs, you should proceed as follows when assigning them:
If the openFT instance has a network address with a DNS name, you should use this as the ID. You can create an “artificial” DNS name for an openFT instance, by placing part of a name, separated by a period, in front of an existing “neighboring” DNS name.
If the openFT instance does not have a DNS name, but is connected to a TCP/IP network, you should use the ID %ipn.n.n.n (n.n.n.n is the IP address of the local openFT instance, minus the leading zeros in the address components).
If the openFT instance is connected to an ISDN network rather than a TCP/IP network, you should use the ID %isdnmmmmmmmm (mmmmmmmm is the ISDN call number, including country and local prefixes).
If the openFT instance is connected to an X.25 network (but not to TCP/IP or ISDN), the ID should begin with %x25 and the X.25 number should contain the NSAP, where necessary (e.g. %x25mmmmmmmmmmNSAP).
The form of instance ID used internally by openFT for partners using a version earlier than V8.1, (i.e. %.<processor>.<entity>), should not be used for your own openFT instance.
