ABSTRACT:
A host data processing system which includes a plurality of input/output devices operates under the control of an enhanced version of the UNIX operating system. The host system includes an emulator which runs as an application process for executing user emulated system (ES) application programs. The emulator includes a number of emulated system executive service components operating in shared memory and an interpreter, an emulator monitor call unit (EMCU) and a number of server facilities operating in the host memory. The ES executive service command handler and file management components are extended to accommodate dual decor copy command which invokes the file management component to copy files in either direction between the host system and emulated system. The server facilities include mechanisms for performing a trusted user level validation when the dual decor copy command is invoked and access control checking at file access which ensures security relative to preventing both unauthorized user access and compromises in user data through improper use of the copy command.
