You can attach more than one host simultaneously to the Teradata Database. The hosts are identified in the configuration by:
- A host number
- A logical host ID
- An associated host type designator
You assign the host a number between 1 and 1023.
The host type designator specifies the host data format.
The system generates the16-bit logical host ID based on the assigned host number and the host type. The value is equal to the host number + the host type value.
