Windows 3494 Enterprise Tape Library Driver Windows The software consists of a tape library service that communicates directly with the Library Manager of the 3494 Enterprise Tape Library through LAN, a utility program that provides a command-line interface to the service, and a static library and DLL that can be used to provide a communication interface with the service. A typical environment for the Windows Automated Tape Library Service is a workstation running Microsoft Windows operating system that acts as a data server on a network with SCSI tape devices providing backup or restore and data server functions. The IBM Automated Tape Library service is provided in the installation package. This service is installed with STARTUP=AUTOMATIC, which means that it is started when the Microsoft Windows operating system is started. An application program may access those functions through API calls. The interface is described in the IBM Tape Device Drivers: Programming Reference. The subroutines in this module communicate with the Enterprise Library Manager to perform the various library operations. The service communicates with the Library Manager through TCP/IP. The c:\winnt\ibmatl.conf configuration file is used to define the type of attachment for each library. Refer to "Defining the Symbolic Name to the Service" on page 244 for more information. Data Flow The software described in this chapter covers the library driver. The interface between the application and the library driver is described in the IBM Tape Device Drivers: Programming Reference. Figure 64 on page 241 illustrates the data flow. 240 IBM Tape Device Drivers Installation and User's Guide
