Connecting to SAP ASE

SAP ASE can communicate with other SAP ASEs, Open Server applications, and client software on the network.

Clients can talk to one or more servers, and servers can communicate with other servers using remote procedure calls. For products to interact with one another, each must know where the others reside on the network. This network service information is stored in the interfaces file.

• The interfaces File
  The interfaces file, which lists the name and address of every known server, is usually named interfaces, interface, or sql.ini, depending on the operating system.
• Directory Services
  A directory service manages the creation, modification, and retrieval of network service information. Directory services are provided by platform or third-party vendors and must be purchased and installed separately from SAP ASE. Two examples of directory services are Registry, and Distributed Computing Environment (DCE).
• LDAP as a Directory Service
  Lightweight Directory Access Protocol (LDAP) is an industry standard for accessing directory services. Directory services allow components to look up information by a distinguished name (DN) from an LDAP server that stores and manages server, user, and software information that is used throughout the enterprise or over a network.
