How Adaptive Server listens for client connections

Adaptive Server uses the interfaces file to determine the address at which it should listen for clients. When you start Adaptive Server, it performs the following steps:

  1. Determines its own name by checking the value of the DSLISTEN environment variable

  2. Looks in the interfaces file for an entry whose name matches the DSLISTEN name and finds the corresponding master line

  3. Uses the network information provided by the master line to listen for queries
