You can choose to use an interfaces file or a Directory Service to provide information about the servers in your installation.
The interfaces file contains network and security information for servers. If you plan to use security services, the interfaces file must include a “secmech” line, which gives the global identifier or identifiers of the security services you plan to use.
Instead of using the interfaces file, Adaptive Server supports Directory Services to keep track of information about servers. A Directory Service manages the creation, modification, and retrieval of information about network servers. The advantage of using a Directory Service is that you do not need to update multiple interfaces files when a new server is added to your network or when a server moves to a new address. If you plan to use security services with a Directory Service, the secmech security attribute must be defined. It must point to one or more global identifiers of the security services you plan to use.
