This chapter introduces the XAPI client interface to ACSLS and describes the XCMD interface that enables you to enter commands targeting an ACSLS server with XAPI.
The XML API (XAPI) is Oracle's StorageTek API that enables StorageTek clients and servers to communicate using a common protocol over TCP/IP.
With the introduction of this XAPI, clients who were previously required to use an MVS based server (Oracle's StorageTek Host software Component) for real tape processing can now use ACSLS (with XAPI support enabled) as follows:
An SMC client on MVS can now request real tape requests from an ACSLS server with XAPI support enabled (without requiring MVS/CSC).
For more information, refer to the ELS publication Configuring and Managing SMC.
A VM Client can now request real tape services from an ACSLS server with XAPI support enabled.
For more information, refer to the ELS publication VM Client Installation, Configuration, and Administration Guide.
The XAPI service is supported for ACSLS 8.4 and later releases. Refer to the StorageTek ACSLS 8.4 Installation Guide for more information about installing and configuring the ACSLS XAPI service.
The ACSLS cmd_proc component is a command-line interface for ACSLS that enables customers to manage an ACSLS system and the libraries that ACSLS controls.
Refer to the Overview chapter in the StorageTek Automated Cartridge System Library Software Administrator's Guide for more detailed information on using cmd_proc.The XCMD command is an extension of the ACSLS cmd_proc that enables users of the ACSLS XAPI server component to enter a limited number of XAPI server user and administrator requests from the existing ACSLS cmd_proc component when the ACSLS XAPI server component is installed and active.
See Chapter 3, "XCMD XAPI Configuration and Administration Commands" for information about XAPI server commands you may enter from the ACSLS cmd_proc using the XCMD command.
See Chapter 4, "XCMD XAPI Server Operator Commands" for information about XAPI operator commands you may enter from the ACSLS cmd_proc using the XCMD command.
Additionally, you can use the SMC/MVS Route command or the VM/Client Route command to issue XAPI server operator commands, XCMD configuration and administration commands, and HSC/VTCS XAPI commands from an MVS or VM host. However, certain parameter restrictions apply.
See Chapter 5, "XCMD Support for XAPI User Requests and HSC/VTCS Commands" for information about supported HSC/VTCS commands and other XAPI requests, and parameter restrictions.
