How SAP ASE Determines Which Directory Service Entry to Use

SAP ASE uses directory services to determine the address at which to listen for clients.

When you start SAP ASE, it:
  1. Looks for the server name supplied in the command line -s option. If the server name is not supplied in the command line, it determines its own name by checking the value of the DSLISTEN environment variable. If the DSLISTEN environment variable is not set, SAP ASE assumes that the server name is SYBASE.
  2. Looks in directory services for an entry that matches the name found in the steps above.
  3. Uses the network information provided by the directory services entry it has found to listen for client connections.
