All Implemented Interfaces:

FunctionInterface, VersionInfoInterface

public class zOSTSOCommandLine
extends Function

The zOSTSOCommandLine Function Component executes specified commands in zOS TSO command line. It uses APPC protocol to communicate with the zOS environment.

In order for the zOS TSO Command Line Function Component to successfully connect and execute commands the APPC should be started and running on the zOS machine. Also this function component can execute commands only on the same machine on which the IBM Tivoli Directory Integrator is running.

The connection to the MVS is maintained by four native methods implemented on the program language 'C' which on the other hand use REXX script to execute commands on behalf of the IBM Tivoli Directory Integrator.
